Patent Description:
Generally, when fishing deep-field fish, such as in the case of boat fishing, an electric fishing reel ("fishing reel") has been widely used.

Conventionally, this type of fishing reel is provided with a line-length measuring device that measures the length of a wound or unwound fishing line based on the rotation speed of a spool in order to improve the catch by accurately adjusting the fishing depth, and the values measured by the line-length measuring device appear on an indicator provided on the reel body.

As such a fishing reel, Patent Literature <NUM> discloses a fishing reel including a spool rotatably supported by the side plates of the reel body therebetween, a winding speed detection means that detects the winding speed during the winding operation of a fishing line wound on the spool, and an indicator that displays the values detected by the winding speed detection means.

<CIT> discloses an electric fishing information recording and storage device which may comprise a module adapted for recording the cumulative number of casts made with a rod and reel combination.

<CIT> discloses a fishing reel which includes a communication chip for establishing a communication connection with an external electronic terminal and exchanging information, in particular information related to casting posture, direction, speed and distance calculated on the basis of acceleration data and angular velocity data.

<CIT> discloses an angling apparatus configured to identify angling events such as cast events and to calculate an angler score.

However, in the fishing reel disclosed in Patent Literature <NUM>, detection values of winding speed are displayed on an indicator provided on the reel body, but are not intended to be transmitted to the outside of the reel. Further, even if the fishing reel information can be displayed, the fishing reel disclosed in Patent Literature <NUM> only displays specific information of the reel though there are a variety of fishing information, such as a lure, fishing images and a fishing environment. There was, therefore, a problem that the information is extremely limited compared with the information generally wanted by fishermen. On the other hand, there was also a problem that providing a variety of fishing information alone is not enough to further improve fishermen's satisfaction with fishing.

The present invention has been made in view of the above circumstances, and the objective thereof is to provide a fishing information management system including a fishing rod at which a fishing reel with a spool capable of winding a fishing line is attached, and that can calculate a level of fishing skill from a variety of fishing information. Other purposes of the present invention will become apparent with reference to this specification in its entirety.

A fishing information management system according to claim <NUM> is provided.

In a fishing information management system according to an embodiment of the present invention, the fishing tools are configured to include at least the fishing reel, the fishing rod, the fishing line, a hook, and a rig.

In a fishing information management system according to an embodiment of the present invention, the operation environment of the fishing tools is configured to include at least the start time of use, the end time of use, the weather condition during use, and the place of use, of the fishing tools.

In a fishing information management system according to an embodiment of the present invention, the operation/environment information detector further comprises a fishing rod operation information detector (fishing rod operation information detecting unit or fishing rod operation information detecting portion) that detects the operation information of the fishing rod.

In a fishing information management system according to an embodiment of the present invention, the operation information of a fishing reel is configured to include at least one of a pulled-out amount of a reel's drag, a pulling-out speed of the reel's drag, a spool rotation start point, a spool rotation end point, a spool diameter, a maximum rotation speed of a spool, a rotation speed history of the spool, a brake setting, a motion of a fishing rod.

In a fishing information management system according to an embodiment of the present invention, the operation information of a fishing rod is configured to include at least one of the speed, the acceleration, the deformation amount, the motion, and the casting method, of the fishing rod.

In a fishing information management system according to an embodiment of the present invention, the level of skill of casting is calculated from the backlash information and at least one of a flying distance of a reel, a maximum rotation speed of the reel, or a time required to retrieve a rig and cast out the rig again.

According to the above embodiment, it is possible to provide a fishing information management system that includes a fishing rod to which a fishing reel with a spool capable of winding a fishing line is attached, and that can calculate a level of fishing skill from a variety of fishing information.

Components common in the plurality of drawings are denoted by the same reference numerals through the plurality of drawings. It should be noted that each of the drawings is not necessarily scaled for convenience of explanation.

A catch in fishing is affected by factors both related and unrelated to a user himself/herself, that is, not only fishing skills, but also weather conditions and appetite of fish. Many fishermen are aiming to improve their skills to increase catch, but it may be inappropriate to use the number of fishes caught as an indicator of the fisherman's skills for the reasons described above.

In the present invention, an operation applied to a fishing rod or a fishing reel is detected and calculated, thereby making it possible to index the skills of a fisherman. The fisherman's skills can be subdivided into various items such as how to select fishing tools and a fishing spot. The present invention, however, covers fishing tool handling skills. The fishing tool handling skills can be further embodied and subdivided. In the present invention, the fishing tool handling skills are classified as follows.

Hereinafter, specific methods of calculating the above will be described.

First, a basic configuration of a fishing information management system <NUM> will be described with reference to <FIG>. <FIG> shows a configuration of the fishing information management system <NUM> according to an embodiment of the present invention. As illustrated, the fishing information management system <NUM> according to an embodiment of the present invention includes a fishing reel <NUM>, a fishing rod <NUM>, a rig <NUM> and an information processor <NUM>.

Like general fishing reels, the fishing reel <NUM> can be operated in the following manner.

A threshold of a tension, which is a set value, is set by winding a fishing line <NUM> on a spool <NUM>, switching between the states in which the fishing line <NUM> can be, and cannot be, reeled out from the spool <NUM>, and idling the spool <NUM> applying a tension equal to or greater than a set value to the fishing line <NUM> (drag function). In a double-bearing reel, braking force to prevent backlash upon casting is adjusted.

Further, the fishing reel <NUM> detects, and transmits to an information processor <NUM>, part or all of the above operations and states. The details will be described later. Like general fishing rods, the fishing rod <NUM> has the fishing reel <NUM>, and guides the fishing line <NUM>. A user can manipulate the fishing line <NUM> as necessary by operating the fishing rod <NUM>. The fishing rod <NUM> detects, and transmits to the information processor <NUM>, part or all of the operations and states of the fishing rod <NUM>. The details will be described later.

The rig <NUM> is attached to one end of a fishing line <NUM>, and has a hook to be bitten by a fish. In this embodiment, a hook is attached within a lure (artificial bait) <NUM>. Further, various types of rigs are used depending on the target fish or fishing method, and a float, a weight, a ground bait container, a balance, and the like are used as necessary. In an embodiment of the present invention, an operation detection means such as an acceleration sensor is provided in part of the rig, transmits the operation of the lure <NUM> to the information processor <NUM>. The operation detection means is waterproofed and sealed in part of the rig together with a power source, storage means and communication means. The reel <NUM>, the fishing rod <NUM> and the rig <NUM> are hereinafter collectively called the "tackle".

The information processor <NUM> accumulates detection results from the respective components constituting the tackle through a receiver (receiving unit or receiving portion) <NUM>, and creates an operation information list aggregating operation information upon each start of unwinding a fishing line, using a list creation portion (list creation unit) <NUM>. The information processor <NUM> may be, for example, a portable information terminal (smart phone). Further, a fishing information processor <NUM> may be incorporated in a fishing reel <NUM> or the fishing rod <NUM> to constitute part thereof. Alternatively, part of the fishing information processor <NUM> may be incorporated in the fishing reel <NUM> or the fishing rod <NUM>. Part or all of the information processor <NUM> may also be located in a server (cloud) on the Internet.

<FIG> is a diagram illustrating a mechanical component configuration of the reel <NUM>: (A) is a case when using a double-bearing-type reel as the reel <NUM>; and (B) is a case when using a spinning-type reel. First, a double bearing reel 10A will be described. A spool 11A can wind the fishing line <NUM>, and it is possible to wind up the fishing line <NUM> when the spool is rotated forward by an operation portion (operation unit) 14A.

A clutch <NUM> can select the connection/disconnection of the power transmission to the operating portion 14A. In the connected state, a winding can be made by the operation portion 14A, and in the disconnected state, the spool 11A can be freely rotated in the forward and backward directions, so that the fishing line <NUM> can be reeled out. A drag device <NUM> can idle the spool <NUM> when a load equal to or greater than the tension set for the fishing line <NUM> is applied. The operation portion 14A is configured, for example, as a handle, and transmits the rotation operation by a user to the spool 11A via a transmission mechanism such as a gear, so that the spool 11A can be rotated forward. The operation portion <NUM> may be a combination of an operation member such as a lever, and a power source such as a motor. A braking device <NUM> can also exert braking force on the spool. This suppresses the occurrence of backlash upon casting. Said braking force can be set by a braking force setting portion (braking force setting unit) <NUM>.

Next, a spinning reel 10B will be described. A spool 11B is fixed to the reel body via a drag device 13B. The drag device 13B can idle the spool 11B when a load equal to or greater than a tension set for the fishing line <NUM> is applied. The fishing line <NUM> is guided to a line guide 12B and is wound on the spool 11B when the line guide 12B rotates around the spool 11B. The line guide 12B is held at the end of a rotor rotatably supported with respect to the reel body, and guiding of the fishing line <NUM> is enabled and disabled by opening and closing a bale arm. When the bale arm is open, the fishing line <NUM> cannot be wound up but can be reeled out. When the bale arm is closed, the fishing line <NUM> can be wound up but cannot be reeled out. An operation portion 14B is configured, for example, as a handle, transmits the rotation operation by a user to a rotor via a transmission mechanism such as a gear, so that the line guide 12B can be rotated forward.

<FIG> is a diagram illustrating a basic configuration of the fishing reel <NUM>. The fishing reel <NUM> has a detector (detecting unit or detecting portion) <NUM> to detect various operations by a user and the state of the reel. The detection results are sent to a calculator (calculating unit or calculating portion) <NUM>, and are transmitted to the information processor <NUM> via a communication portion (communication unit) <NUM> after arithmetic processing or temporary storage in a storage <NUM> as necessary. The detector <NUM> includes the followings. Some may be omitted due to limitations of costs, sizes and the like. A tension detector (tension detecting unit or tension detecting portion) <NUM> detects a tension acting on the fishing line <NUM>. It can be realized by techniques known in the art, such as detecting by a strain sensor force acting on the rotation axis of the pulley that guides the fishing line <NUM>.

A spool rotation detector (spool rotation detecting unit or spool rotation detecting portion) <NUM> detects the rotation of the spool <NUM>. It can be realized by known means such as an incremental-type rotation sensor using a photo interrupter or magnetic sensor. A non-contact type rotation sensor is desirable to achieve smooth rotation of the spool <NUM>.

A winding operation detector (winding operation detecting unit or winding operation detecting portion) <NUM> detects the rotation of the operation portion <NUM>. It can be realized by attaching a rotation sensor to the operation portion <NUM>, or a gear or the like that rotates in conjunction with the operation portion <NUM>. It can be realized by known means such as an incremental-type rotation sensor using a photo interrupter or magnetic sensor. A non-contact type rotation sensor is desirable to achieve smooth rotation of the operation portion <NUM>. The amount of idling by the drag device <NUM> can be calculated by taking the difference between the winding operation detector <NUM> and the spool rotation detector <NUM>.

An unwindable state detector (unwindable state detecting unit or unwindable state detecting portion) <NUM> detects whether or not the fishing line <NUM> can be unwound from the fishing reel <NUM>. In the exemplary double-bearing reel 10A described above, it can be realized by detecting the connection status of the clutch <NUM>. A limit sensor or the like may be attached to part of the member on which the clutch operates. In the exemplary spinning reel 10B, a limit sensor or the like may be attached to part of the member on which a bale arm operates.

A set drag force detector <NUM> detects a set tension that is a threshold at which the spool <NUM> idles. It can be realized by detecting charging force acting on a friction member in a drag device by a pressure sensor or the like. A set braking force detector (set braking force detecting unit or set braking force detecting portion) <NUM> detects a set value of the braking force for backlash suppression. It can be realized by providing a volume resistance or the like to the braking force setting portion <NUM>. In a type of braking device that sets braking force by computer, the set braking force detector <NUM> can by realized by obtaining a command value to the braking device.

The state and the operation information of the reel <NUM> can be obtained or calculated by calculating by the calculator <NUM> the value obtained by the detector <NUM> as necessary. More specifically, a tension acting on the fishing line, winding amount of the fishing line, pulled-out amount of the drag device, set drag force, unwindable state, and set value of braking force can be obtained. Further, the winding speed and the amount of tension change, which are the time derivative values of the foregoing, can also be calculated.

Next, the components of the electric parts of the fishing rod <NUM> will be described in detail with reference to <FIG>. The fishing rod <NUM> has a detector <NUM> that detects various operations by a user and the state of the fishing rod <NUM>. The detection results are sent to the calculator <NUM>, and are transmitted to the information processor <NUM> via the communication portion <NUM> after arithmetic processing or temporary storage in the storage <NUM> as necessary. The calculator <NUM>, the communication portion <NUM>, and the storage <NUM> at this time may be shared with those of the fishing reel <NUM> by using a wired connection or the like, or may be dedicated to the fishing rod <NUM>, or may be disposed within the fishing reel <NUM> or on the fishing rod <NUM>.

The detector <NUM> includes the followings. Some may be omitted due to limitations of costs, sizes and the like. A deflection detector (deflection detecting unit or deflection detecting portion) <NUM> detects the deflection (bend) of the fishing rod <NUM>. It can be realized by providing a strain sensor at various portions of the fishing rod <NUM>. The direction detector (direction detecting unit or direction detecting portion) <NUM> can detect the direction in which the fishing rod <NUM> is oriented by detecting the geomagnetic direction. The acceleration detector (acceleration detecting unit or acceleration detecting portion) <NUM> detects the acceleration in the translation direction of the fishing rod <NUM>. It can be realized using an acceleration sensor known in the art, such as a piezoresistive method and a capacitance detection method.

Further, an angular velocity detector (angular velocity detecting unit or angular velocity detecting portion) <NUM> detects the angular velocity of the fishing rod <NUM> (speed in the rotation direction). It can be realized using a gyro sensor known in the art, such as a method for detecting a frequency change of the vibrated piezoelectric element. Incidentally, a sensor called a nine-axis motion sensor that detects the direction, acceleration and angular velocity of each of orthogonal three axes can be used as the direction detector <NUM>, the acceleration detector <NUM>, and the angular velocity detector <NUM>. Hereafter, these are called motion sensors. The attitude and the operation of the fishing rod <NUM> can be obtained by calculating the detection results described above. The motion sensor may be disposed in the reel <NUM>.

Next, a method of calculating the skill of handling fishing tools will be described. First, a casting skill will be described. A user with a high casting skill can realize the following when casting out a rig.

Therefore, it is evaluated that the longer the measured casting distance (flying distance) of a rig is, the higher the casting skill is, that the lower the detected occurrence of line entanglement is, the higher the casting skill is, and further, that the shorter the measured time required to retrieve a rig and cast out the rig again is, the higher the casting skill is. The casting skill may be calculated using part of said elements, or a weighted average calculated using weights determined according to the reliability of said elements.

Next, a method of measuring a flying distance will be described with reference to a case where the double-bearing fishing reel 10A is used. A user performs the following when casting out a rig.

Therefore, when the unwindable state detector <NUM> detects that the clutch is open, the fishing line is judged to be ready to be unwound, and the count value of the spool rotation is reset. Thereafter, when a spool rotation detector (spool rotation detecting unit or spool rotation detecting portion) detects that the spool rotates backward, the count value of the spool rotation is increased according to the detected rotation amount.

When the rotation of the spool stops, the unwinding of the fishing line is judged to be completed. A flying distance can be calculated from the count value of the spool rotation at this time. The unwound length of the fishing line is uniquely determined by the amount of rotation of the spool if the elongation or slack of the fishing line is negligible and therefore, can be calculated by a known conversion formula. Though the horizontal flying distance of the rig and the unwound length of the line may differ depending on the trajectory of the rig, no significant difference is seen in ordinary casting. Therefore, the unwound length of the line can be regarded as the flying distance of the rig.

If the flying distance of the rig obtained in this way is equal to or greater than a predetermined value, the casting skill is rated high. It should be noted that even highly skilled user often casts a rig at a short distance according to the situation of a fishing spot. It is therefore often inappropriate to rate the casting skill low even if the minimum or average flying distance is short.

Further, the higher the maximum rotation speed of the spool is upon casting, and the faster the angular velocity of the fishing rod is, the farther a rig can be cast out. Therefore, the casting skill may be rated high when these values are equal to or greater than predetermined values.

Incidentally, the level of difficulty of casting out a rig varies depending on weather conditions and types of tackles, and the flying distance tends to increase under the following conditions, for example.

Therefore, it is even better to input information on a rig and a fishing rod used for the tackle, weather conditions, and the like to the information processor <NUM>, and to evaluate the casting skill by correcting the influence thereof. For example, when a short fishing rod is used to cast a distance of <NUM>, a higher rating can be given than when a long fishing rod is used to cast the same distance.

Next, a method of detecting the occurrence of line entanglement will be described. If a spool rotates faster than the unwinding speed of the fishing line when casting using the double-bearing fishing reel 10A, a portion of the fishing line is not reeled out and stays in the reel, resulting in entanglement, which is called backlash.

In the event of the occurrence of line entanglement, if the line is badly entangled, the entangled line hinders the normal rotation of the spool, which makes it impossible to perform a winding operation. Even when the line is not so badly entangled, it is desirable to eliminate the slack of the line in order to avoid any trouble that may arise thereafter. Therefore, a user needs to disentangle the line before performing the winding operation. The user needs to follow the following steps to disentangle the line.

In the event of performing the above operations, the user repeats the operation of pinching the slack line and pulling out the same by stretching his/her arm as shown in <FIG>. The line wound on the spool is pulled out intermittently a plurality of times by approximately several tens of centimeters to <NUM>. This operation is required many times when the line is badly entangled, but it is done soon otherwise.

Next, a method of detecting line entanglement will be described in more detail. Among the methods of using fishing reels, pulling out the line as described above is specific to the operation of fixing the backlash. Therefore, detecting this operation and measuring the duration thereof make it possible to assume the occurrence of backlash and the severity of the line entanglement.

This specific calculation method will be described with reference to the flowchart in <FIG>. When detecting the completion of casting, the program starts. The completion of casting can be detected, for example, when the clutch is switched from off to on, or when the spool rotating at a high speed stops, or becomes a predetermined value or less.

After the program starts, the spool rotation speed is constantly monitored in (S1). Next, in (S2), the subsequent process is changed according to the result of the last judgement made on the backlash. Since the absence of backlash is set as a default value, the process moves from (S2) on to (S3) when it is executed first time.

In (S3), the number of times when a spool rotation speed ω exceeds the rising threshold which is the rotation speed ω1 (predetermined rotation speed) within the past T1 seconds is counted. That is, when ω1 is <NUM>, it is counted in the number of times when ω changes from <NUM> to <NUM>, but not when ω1 remains to be <NUM> or more.

When the count value is N or more, it is deemed that the backlash is now being fixed. It is possible to distinguish between the cases (B) and (C) referred to above by appropriately setting the values of N and T1. The larger N is, the more misjudgment of tug of fish as backlash can be avoided; however, time T1 required to judge the occurrence of backlash increases. In the present embodiment, for example, N and T1 are set to <NUM> and <NUM> seconds, respectively. Further, the value of ω1 may be set to a rotation speed equal to or less than the speed at which a user pulls the line when disentangling the line, and in the present embodiment, for example, it is set to <NUM> per second. This value varies with the diameter of the line wound on a spool.

Upon the completion of the judgement, the process returns to (S1). If the process is in (S2) after it is judged that backlash has occurred, the process moves on to (S4). When the spool is wound in the winding direction at a speed faster than the predetermined value ω2 (-<NUM> in this embodiment), it is judged that a user has fixed the backlash. Once it is judged that the backlash has occurred, it is considered to continue until the occurrence of a winding speed in absolute value larger than the ω2, and the judgement remains NO.

Next, when it is judged in (S4) that the backlash has been fixed, the process moves on to (S3) again the next time and thereafter, and the next backlash fixing operation is detected. When the above detection method detects the occurrence of line entanglement, the casting skill is devaluated. The casting skill is highly evaluated when repeatedly casting without causing line entanglement.

Next, a method of measuring the time required to retrieve a rig and cast out the rig again will be described. Here, the time required to retrieve a rig and cast out the rig again is defined as a time interval from (<NUM>) to the next (<NUM>) among the above-mentioned fishing operations (<NUM>) to (<NUM>). Generally, the shorter the time required to retrieve a rig and cast out the rig again is, the better the catch will be. Since fish may be caught between (<NUM>) and (<NUM>) above, the larger the ratio of time between (<NUM>) and (<NUM>) to the total time of fishing is, the better the catch will be. Since besides (<NUM>) to (<NUM>), the most time consuming is the section between (<NUM>) and (<NUM>), the likelihood of catching fish becomes higher when the operations to be performed during this section are promptly handed. Skilled persons require less time for the section from (<NUM>) to (<NUM>) and tend to catch more fish.

In the case of the double-bearing fishing reel 10A, (<NUM>) is recognized when the unwindable state detector <NUM> detects that the clutch is switched from on to off. Thereafter, (<NUM>) is recognized when the spool rotation detector <NUM> detects that the spool 11A starts rotating. Then, (<NUM>) is recognized when the unwindable state detector <NUM> detects that the clutch is switched from off to on. When the phenomena in (<NUM>) to (<NUM>) occur continuously, a fishing line is recognized to have been reeled out. That point of time of each said phenomena is recorded.

A method of detecting the completion of retrieval of a rig by a retrieval completion detector <NUM> will be described. In most cases, users do not perform winding operations during the period from the completion of collection of a fishing line in (<NUM>) to the next reeling out in (<NUM>). Therefore, when it is detected that the reeling out of the fishing line has started, the time of the immediately preceding last winding operation is the time of completion of collection. Recording this time makes it possible to detect the retrieval of the rig.

The time required to retrieve a rig and cast out the rig again is obtained by calculating the difference in time between the completion of retrieval of the rig and the start of the next reeling out. The casting skill is rated high when the time required to retrieve a rig and cast out the rig again that is measured by the detection method described above is shorter than a predetermined value, and is rated low when it is longer than the predetermined value.

The three evaluation methods described above are only examples of casting skill evaluation methods. There are also other elements that constitute the casting skill, some of which can be calculated by detecting operations on the tackle. They may be calculated by a method using machine learning. That is, a large number of operation data of highly skilled users and inexperienced users are prepared as teacher data. The casting skill may also be calculated by judging the teacher data by an evaluation method using a neural network or data mining.

Next, a method of calculating the reeling skill will be described. Methods of making a fish bite a hook vary with the target fish and fishing method. Among them are methods and situations in which the change in the speed of pulling a lure is small and the catch increases when the lure can be moved at a constant speed. However, because of the difference in operability according to the handle angle when rotating the handle by hand, it is not easy to rotate the handle at a constant speed, and persons with higher skills can rotate the handle at a more constant speed. In such a fishing method, if a change in the rotation speed of the handle is detected, the smaller the speed change is, the more highly the reeling skill can be rated.

The speed of rotating the handle can be detected by the winding operation detector <NUM>. The difference between the maximum value and the minimum value of said values monitored for a certain period of time is the change in speed of rotating the handle during said period. It is better to exclude the case where the handle is not moving from the evaluation target since the change in speed is also zero in this case.

The evaluation method described above is only an example of reeling skill evaluation methods. Further, there are many other elements that constitute the reeling skill depending on the target fish or fishing method, some of which can be calculated by detecting operations on the tackle. They may be calculated by a method using machine learning. That is, a large number of operation data of highly skilled users and inexperienced users are prepared as teacher data. The reeling skills may also be calculated by judging the teacher data by an evaluation method using machine learning such as a neural network.

Next, a method of calculating the fighting skill will be described. As this value is obtained by evaluating the moment when a fish bites at the rig <NUM>, it is necessary to first detect this moment. For example, a fish bite can be detected when the tension for the fishing line detected by the tension detector <NUM> becomes a predetermined value or more, when the deflection of the fishing rod detected by the deflection detector <NUM> becomes a predetermined value or more, or when the fishing rod vibrates at a specific frequency. One criterion for evaluating fighting skills is the change in tension from a bite by a fish to the landing of the fish. When the tension of the fishing line suddenly weakens, the fishing line easily slacks, which increases the risk of fish coming off the hook. When such a state is detected, the fighting skill is rated low. Further, if the tension acting on the fishing line rises to near the breaking tension due to inappropriate setting of a drag device, inappropriate operation of a rod or the like, the risk of breakage of the fishing line increases. When such a state is detected, the fighting skill is rated low.

If the length of the unwound fishing line becomes nearly zero with the tension of the fishing line maintained or with the deflection of the fishing rod kept at a predetermined value or more, it can be judged that the fish has been successfully landed. In such a case, the fighting skill is rated high. Further, the shorter the time required to catch and collect a fish is, the more highly the fighting skill may be rated.

In this manner, the fighting skill can be evaluated by calculating the detection results of the detectors <NUM> and <NUM>. A machine learning method such as a neural network is effective because judgement by a combination of multiple detection results works well.

In the above example, the overall skill of handling fishing tools is divided into three categories: the casting skill, the reeling skill and the fighting skill. The overall skill may be obtained by calculating a weighted average of these three skills. Since this makes it possible to indicate the skill with a single index, it will be more easily handled when plotted on a chart or the like.

The importance of each skill varies with the target fish and fishing method. For example, in the case of surf-fishing for sillaginoid, the casting skill is important because it is often more advantageous to cast farther, but the fighting skill is less important because the swimming power of the target fish is weak. On the other hand, when going for a big one in boat fishing in deep sea, the casting skill is less important because a rig is often just dropped on the sea floor, but the fighting skill is important because the swimming power of the target fish is strong. Therefore, the weights determined for each item may be changed when calculating a weighted average depending on the target fish or fishing method.

Further, the skill of handling fishing tools generally improves with greater experience. Therefore, the skill can be more highly rated with increase in the hours to handle the fishing tools and the frequency in reeling out a fishing line. That is, the skill value is increased every time the hours of use of the reel <NUM> and the fishing rod <NUM> exceed a predetermined time, monitoring said used hours. Alternatively, the skill value is increased every time the number of casting of a rig exceeds a predetermined value, monitoring the unwindable state detector <NUM>, the spool rotation detector <NUM>, and the winding operation detector <NUM> to count the number of castings of the rig. This value may be added to each element of the casting skill, the reeling skill, and the fighting skill according to the state and method of use of the tackle, or may be counted, separately defining skills of experience, as the value thereof.

The skill value calculated by the above method is stored in the storage <NUM> and displayed on an indicator <NUM> as necessary. <FIG> show examples indicating skill values.

First, in <FIG>, the items constituting the skill of handling fishing tools (overall skill, which is the sum of the elements in the present embodiment) are indicated. This helps a user understand his or her own skill. At this time, a visual presentation is preferable as shown in <FIG>, which includes plotting each item on a chart. Further, in the present embodiment, rankings are displayed in accordance with the overall skill. By doing so, it is possible to improve users' motivation.

Next, <FIG> shows an example indicating the catches and the skill values of users who participated in a fishing competition. In this manner, the skills of multiple users displayed and compared may be used as a ranking criterion.

Further, <FIG> shows the time change in each skill value for each month. On the other hand, <FIG> shows a display example based on the amount of change in the skill value for a day. In this manner, displaying time changes and commendations can give users a realization of an improvement in their skills of handling fishing tools, which makes it possible to improve users' motivation.

Further, <FIG> shows skill values for each type of the tackles. Further, <FIG> shows casting skills value corresponding to the braking force of the braking device <NUM>. The horizontal axis represents the types of operations that can be performed by a user, or tackles, and the vertical axis represents skill values, which can be used as a criterion to judge which tackle should be used, or can be used to optimize the set value of the tackle. For example, in the example in <FIG>, using the braking force of the brake <NUM> is found to be most advantageous upon casting.

Next, the fishing information management system <NUM> according to an example useful for understanding the disclosure, not within the scope of the claims, will be described. The fishing information management system <NUM> according to an embodiment of the present invention is configured to include the fishing reel, the fishing rod, and the fishing information processor.

More specifically, the fishing information management system <NUM> according to an example useful for understanding the disclosure, not within the scope of the claims, has the fishing rod to which the fishing reel with a spool capable of winding a fishing line is attached, and is configured to include the operation/environment information detector that detects information on the operation of the fishing tools and the operation environment when the fishing tools including the fishing reel and the fishing rod <NUM> are used, the calculator that calculates the skill levels in operating fishing tools from information on the operation of the fishing tools, a storage that stores the detection values and the skill levels, and the indicator <NUM> that displays at least either of the detection values or the skill levels.
