     TECHNICAL FIELD 
     The present invention generally relates to an apparatus, device for locating and separating objects from a medium in which such objects are disposed and for use in conjunction with a metal detector. In particular, the present invention relates to a device that allows a user to scoop and simultaneously sift a medium with one hand and forearm making it an ergonomic handle. Otherwise, the device may be hung from an article of clothing such as when not being used to sift through the medium. 
     BACKGROUND OF THE INVENTION 
     There is an increasing trend in the number of people becoming interested in amateur prospecting, treasuring hunting, metal detecting, amateur geology, and amateur archaeology. A metal detector may be used to pursue these various activities by identifying metallic objects arranged within the surface of the earth. In many instances, these activities may take place in beach sand. During these “beachcombing” operations, a user walks along a beach carrying a metal detector. A distal end of the metal detector includes a sensor coil. A proximal end includes a grip and/or arm support with control electronics, a power source and an indicator means. The indicator means alerts the user when the sensor coil passes across or in near proximity to a metallic object. 
     The inventor, Mr. Charles A. Boll, has attempted, through trial and error, to arrive at a suitable apparatus which could be used both for digging, scooping and for sifting metallic objects from sand and other dirt taken from the earth. Thus, the device is known as a digger sifter with ergonomic handle. The prior art fails to satisfy the inventor&#39;s needs and possesses numerous disadvantages over the present invention. Typically, the prior art devices cannot be easily carried or suspended in a hand-free manner on the user when not in use. Many prior art devices require two-handed operations when scooping and sifting for hidden or lost items. Moreover, many cannot be used when standing upright to dig and sift to prevent a user&#39;s back and/or knees from becoming sore from bending over excessively during metal detecting operations. Otherwise, they do not comprise an ergonomic handle as claimed in the present invention. Still others require a user to step on a rear of the device or the metal detector and scoop are included as a single heavy device requiring all its weight to be carried on a single arm of the user. For example, see U.S. Pat. No. 4,983,281 to Montelione. 
     Prior devices in the sifting field are exemplified by U.S. Pat. No. 3,976,564 to Holder; U.S. Pat. No. 645,956 to Hyrons; U.S. Pat. No. 657,508 to W. W. Brown; U.S. Pat. No. 681,608 to O. P. Baughman; U.S. Pat. No. 2,005,416 to J. H. Fisher; U.S. Pat. No. 4,983,281 to Montelione; U.S. Pat. No. 4,979,623 to Flanagan; U.S. Pat. No. 4,359,686 to Wherry; U.S. Des. Pat. No. 339,966 to Burnett; and. 
     SUMMARY OF THE INVENTION 
     The present invention provides an apparatus for manually scooping and separating objects from a medium in which such objects are disposed. The apparatus includes means for temporarily scooping a portion of said medium which may contain one or more of said objects, and means for sifting said medium so as to separate said objects from said medium while discarding the sifted medium. 
     In one instance, the present digger sifter with ergonomic handle is easy on the wrist of the operator by means of two locations of body contact. That is, a user passes his arm through a ring or arm sleeve part  5  while gripping a handle  8  arranged horizontal to the ground whereas the prior art does not. The use of two body contacts produces a multiplier effect of by allowing the user to use a larger group of muscles which are stronger than those in the wrist. This effect creates a mechanical advantage that requires minimal movement of the operator&#39;s arm to operate the scoop member  20 . A notch  9  is provided on arm  8  to keep the scoop sifter out of the magnetic field of the metal detector when carrying it or during detection operations. This allows the user to rest the arm muscles until it is used to scoop another object of interest. Two elongated arms provide a support structure for accepting a wide variety of scoops. The scoop  20  may comprise different materials and include various methods of attaching it to the elongated arm members. Bolts, rivets, various threaded shafts, nuts, washers, pins, or any other such fasteners may couple the scoop  20  to the elongated arms. Thus, the tool may be light in weight. 
     Moreover, usage of the tool is easier than prior art ones that require the weight of the user be applied to the rear of the tool. Such prior art devices require a balancing act during use in the ocean surf. The user must hold the metal detector in one hand and the prior art sifting device in the other while attempting to apply the user&#39;s weight onto the back of the tool. The user&#39;s movements are further hindered by ocean waves which continually shift the sand from underneath the user&#39;s feet. Thus, the present invention makes the sport of treasure hunting more attractive with both feet on the ground to opperate. 
     The novel arrangement of parts in the present invention may comprise 25 gauge galvanized hardware cloth having a cross sectional diameter of an individual wire being measured at 0.04″ or 18 gauge thick wire. These sizes are beneficial in passing a medium through the substantially rigid sifter basket  25 . In a preferred embodiment, the range of the aperture-to-total area ration of the mesh material is about 84% which is not found in the prior art. This ratio allows for easy use of the instant invention in both dry and wet sand as well as in shallow water or during scuba diving. 
     The pitched angle of the scoop relative to the parallel elongated arms may be varied by including adjustment openings  22  in the sides of the scoop near where the elongated arms attach. By increasing the pitch of the scoop relative to the horizontal, provides for more aggressive digging to allow more medium into the scoop. 
     In some embodiments of the invention, a longer basket  25  increases the surface area and makes it easier to pass medium through the basket  25 . The larger sized basket is useful in hard packed wet sand. Other embodiments include oval shaped or rectangular shaped scoops that are over sized and which facilitate the faster removal of medium through the larger basket. In one embodiment, a plastic oval shaped scoop and oval shaped scoop with V-bottom, 14 gauge galvanized steel that is 1¼ inch wide strap of sheet metal is mounted to the front of the scoop to create a blade which reduces wear and abrading of the forward edge of the scoop member. 
     The present tool is used by pulling the scoop from 2 to 8 o&#39;clock with the operator&#39;s feet arranged at 7 and 5 o&#39;clock. The scoop is pulled towards the operator to capture medium. Thereafter, the scoop is shaken back and forth to sift medium through the scoop  20  and basket  25 . By twisting the arm and wrist left and right, the rear tip speed of the basket is increased. 
     The present invention, as described herein, is particularly well suited for use, in conjunction with a portable metal detector, to locate and separate objects from sand, principally beach sand. It will be appreciated by those skilled in the art, however, that the present invention may be used for locating and separating other types of objects from various other media. Thus, the phraseology and terminology “objects” as used hereinafter in this context is intended to include and embrace anything which is perceptible by one or more of the senses, especially something that can be seen and felt, and is not limited or restricted to metallic items. Furthermore, the terminology and phraseology “medium” as used hereinafter in this context is intended to connote generally any surrounding or pervading substance in which bodies or objects exist or move, and includes, but is not limited to, sand, earth, water, dirt, mud, gravel, etc. 
     A digger sifter with ergonomic handle comprises an arm and hand supported elongated handle assembly including a pair of elongated arms. The elongated arm handle assembly includes a proximal end and a distal end. An arm ring attaches at the proximal end of the arm supported elongated handle assembly. The operator passes his hand and a portion of his arm through the arm ring such that the proximal end of the elongated handle assembly is constrained by a portion of the operator&#39;s arm. A scoop, having an opening that is arranged against a wire basket, has a cutting edge that cuts into the medium to be sifted. The opening is adapted to accept the medium having an object arranged therein. The scoop and wire basket attaches to the distal end of the arm supported elongated handle assembly. A cross brace attaches to the pair of parallel elongated arms intermediate the proximal and distal end of the arm and hand supported elongated handle assembly for providing a surface which may be gripped by the user of the digger sifter. One end of the cross brace extends outward from an elongated arm and includes a notch adapted to attach the sifter to an operator&#39;s belt or pants pocket when not in use, preferably on the back pocket out of the way when using a metal detector as shown in  FIGS. 3A-3B . A stirrup-shaped grip fastens to the cross member or the D-stirrup can be omitted and a filler piece can be added to the cross brace with appendages. 
     An arm and hand supported elongated ergonomic handle assembly comprises a pair of parallel elongated arms. Each parallel elongated arm includes a proximal end and a distal end. A circular arm ring attaches between the proximal ends of the pair of parallel elongated arms. A scoop, including a front edge with a cutting edge, is arranged between the distal ends of the pair of parallel elongated arms and having an opening. The cutting edge of the scoop is preferably arranged along a bottom front edge of the scoop such that it bites into a medium having an object of interest. A sifter is arranged against a rear or back side of the scoop opposite the cutting edge. The sifter accepts and sifts media that has been cut by the cutting member and passed into the scoop. The media preferably includes an object of interest which is filtered from the media during the scooping and sifting process. A b-shaped hand grip attaches to the pair of parallel elongated members intermediate the scoop sifter assembly and the circular arm ring. One end of the b-shaped hand grip extends past the exterior edge of one of the elongated members and includes a notch that is adapted to attach the digger sifter with ergonomic handle to an operator&#39;s belt, waistline or pants pocket. That is, the invention attaches to an operator&#39;s belt or pant&#39;s pocket when not in use, preferably on the back pocket out of the way when using a metal detector as shown in  FIGS. 3A-3B . 
     One of the principal objects of the present invention is to provide a lightweight and convenient apparatus for use in conjunction with a metal detector which will allow the user to scoop and sift simultaneously with one hand. Another object of the present invention is to provide an apparatus or device for locating and separating objects from a medium in which such objects are disposed and having an ergonomic handle. 
     It is an additional object of the invention to provide a device of the character described that can be operationally used to scoop and sift dry, as well as hard packed wet sand located at an edge of a body of water. The apparatus is also particularly useful underwater, in shallow water, and deep water during scuba diving operations. 
     It is a further object of the present invention to provide an embodiment of the present invention that can be readily supported from an operator&#39;s clothing when not in use. 
     It is another object to provide a sorting and sifting device in which lateral and rotational stability between the operator and the scooping mechanism is provided to the device by a pair of transversely spaced-apart elongated arm members. 
     It is another object to provide a device in which such laterally spaced apart elongated arms can be attached to scoop members constructed of varying materials and having varying sizes and geometries.

     DETAILED DESCRIPTION OF THE INVENTION 
     The embodiments of the invention and the various features and advantageous details thereof are more fully explained with reference to the non-limiting embodiments and examples that are described and/or illustrated in the accompanying drawings and set forth in the following description. It should be noted that the features illustrated in the drawings are not necessarily drawn to scale, and the features of one embodiment may be employed with the other embodiments as the skilled artisan recognizes, even if not explicitly stated herein. Descriptions of well-known components and techniques may be omitted to avoid obscuring the invention. The examples used herein are intended merely to facilitate an understanding of ways in which the invention may be practiced and to further enable those skilled in the art to practice the invention. Accordingly, the examples and embodiments set forth herein should not be construed as limiting the scope of the invention, which is defined by the appended claims. Moreover, it is noted that like reference numerals represent similar parts throughout the several views of the drawings. 
     Before explaining the present invention in detail, it should be understood that the present invention is not limited in its application or construction to the details of the arrangement of parts and construction illustrated in the accompanying drawings, because the present invention is capable of other embodiments and modifications and of being practiced or carried out in various ways. Furthermore, it should also be understood that phraseology or terminology employed herein is for the purpose of description and illustration only, and not of limitation or restriction. 
     With reference to the drawings, there is illustrated an apparatus  1  according to a preferred embodiment of the present invention. The novel apparatus  1  is especially useful for scooping and separating objects, such as metal coins, jewelry, mollusks, or other objects, from a medium, such as sand, in which such objects may be disposed. 
     The apparatus  1 , which is adapted to be supported from an operator&#39;s arm and hand during use, includes an elongate handle assembly  15  that extends between an arm ring  5  at the handle assembly&#39;s proximal end and a scoop member  20  at the handle assembly&#39;s distal end. The apparatus  1  may be formed from a group of materials consisting of aluminum, galvanized steel, copper, stainless steel, plastics, fiberglass, thermoplastic, polycarbonate, wood, steel, or a combination thereof. 
     The handle assembly  15  comprises a pair of elongated arms  15 A,  15 B. The elongated arms  15 A,  15 B are oriented parallel to each other, and together define “handle plane” (P). In order to provide a clear description of the present invention, the nominal orientation of the apparatus, and of various components of the invention, is described relative to a vertical plane (V) or a horizontal plane (H) which are respectively orientated with respect to the handle plane P. It should be understood, however, that such spatial descriptors should not be construed as restricting operational movement or orientation of the assembled apparatus  1 . 
     An arm ring  5  is provided at the proximal end of the handle assembly  15 , and is attached to the elongated arms at substantially diametrically opposite sides of the arm ring  5 . The arm ring  5  is preferably a closed, circular shape and has an inside diameter  6  that is large enough to allow an operator to insert his/her forearm through it. In a preferred embodiment of the invention, the arm ring is made of PVC plastic, is between 1 and 1-½ inches long when measured in the axial direction, has an inside diameter of 4 inches, and is approximately ¼ inch thick. The arm ring can be advantageously manufactured from 4-inch PVC pipe. In modified embodiments of the invention, the arm ring can have a smaller or larger diameter, so as to be wearable by children or larger persons, respectively. The edges of the arm ring are preferably curved, so as to minimize pressure against the operator&#39;s arm. The edges may be formed in a curved manner or created by turning them with a ⅛″ round router bit and in modified embodiments made of aluminum, galvanized steel, plastics, fiberglass, copper, stainless steel, polycarbonates, wood, steel or metal alloys. 
     The arm ring  5  includes openings and is attached to elongated members by fasteners  50 . In the preferred embodiment of the invention, the fasteners are rivets, but other conventional fasteners, including screws, bolts, welding, bonding or clips or the like can alternatively be used. Likewise, if the device is formed by metallic materials, welding, brazing or the like may be utilized to secure the various parts to implement the invention. 
     A substantially hollow scoop member  20  is provided at the distal end of the handle assembly  15 , and is located between, and attached to, the elongated arms. The scoop member  20  has a forward end and a rear end, a top and a bottom. As will be discussed in more detail below, the forward end of the scoop member includes an edge  21  that is designed to cut into and gather a bulk medium (such as sand) as the device is manually moved forwardly through the medium. In cross-section, the scoop member is a closed geometric shape. As shown in the figures, the cross-sectional shape of scoop member  20  is square as in  FIGS. 2A-2B , but may, in modified embodiments be circular as in  FIG. 2C , diamond as in  FIG. 2D , oval as in  FIG. 2F , or other closed geometric shape.  FIG. 2E  shows a scoop member  20  having an arcuate angled edge relative to the wire basket  25 . By way of example, in the preferred embodiment of the invention, the scoop member is constructed of 4-½ inch square schedule 20 PVC conduit or a fence post jacket. The centerline length of the scoop top (measured between the forward end and the rear end) is shorter than the centerline length of the scoop bottom (measured between the forward end and the rear end) such that the plane of the forward end of the scoop is at an acute angle (A) relative to vertical (V). It should be noted that the scoop member  20  may be formed in any shape with any type of bend. 
     In the preferred embodiment of the invention, each elongated arm  15 A,  15 B is attached to the scoop member  20  with a pair of fasteners, which hold the elongated members  15 A,  15 B in a fixed position relative to the scoop member  20 . Preferably, the first fastener is at a nominally higher elevation than the second fastener, and handle plane P is nominally at an acute angle (B) relative to vertical. In the preferred embodiment of the invention, one or more pairs of adjustment holes  22  is provided in scoop member for varying the nominal angle (B) between handle plane P and vertical V as can be understood when viewing  FIG. 2A . It will be understood that such a configuration (i.e., angled forward end of the scoop member and angled handle plane-to-scoop bottom orientation) facilitates operation of the device in front of an operator as the device is moved forward to scoop up sand (or like media). 
     A closed-ended, perforated basket  25  is attached to the rear end of the scoop member  20  across the opening  23  defined at the back end of the scoop. In the preferred embodiment of the invention, the basket  25  comprises a metallic wire mesh with ½″×½″ spacing such as 25 gauge hardware cloth, (approximately 0.04 inch 18 gauge wire including galvanized coating) having an aperture-to-total area of the mesh material used in constructing the sieve or basket of about 84%. That is, 16% of the basket comprises the cross wire that acts as a sieve to filter objects of interest from a medium. The basket is attached to the outside or inside of scoop member with fasteners through openings  26  arranged in the rear of the scoop  20  as shown in the various figures. In the preferred embodiment of the invention, the forward end of the basket overlaps the rear end of the scoop member by approximately 1 inch, and is attached to the scoop member with rivet fasteners. In the preferred embodiment of the invention, the cross-section of basket is substantially constant in size and shape, is the same size and shape as the cross-section of scoop member, and extends rearward from scoop member parallel to the sides of scoop member. However, in modified embodiments of the invention, the cross-sectional size of basket can increase or decrease as it extends beyond the rear of the scoop member. All seams on the wire basket is soldered or brazed to create a solid basket. 
     A hand grip member, collectively comprising stirrup  11  or filler piece  13 , brace  8  and grip  12  is attached, using pairs of longitudinally spaced-apart fasteners, to elongated arms intermediately between the arm ring and scoop member. In the preferred embodiment of the invention, the elongated arms are approximately 32 inches long for adults, or 24 inches long for children, and the outside distance from the arm ring at the center of the hand grip is approximately 10 inches for an adult, 8 inches for a child, such that the hand grip member can be grasped by a typical operator while the arm ring encircles the operator&#39;s forearm (just below the elbow). The hand grip member preferably comprises a brace member  8 , which may be constructed from a 1-inch long section of 4-inch diameter schedule 40 PVC, and is fastened axially perpendicular to the elongated arms. In the preferred embodiment of the invention, the hand grip member is in the shape of a “D” or stirrup-shape, with the flat side of the “D” being forward of the plane (P) of the elongate arms or filler piece  13 . It should be noted that the overall length of the elongated arms may be longer than that mentioned above. 
     A rigid arm or cross brace  8 , preferably made of ¼-inch thick PVC, is attached to the hand grip member by common fastening means (such as adhesive, plastic weld, screws or rivets), and preferably extends approximately 1-½ to 3½ inches outward of one of the elongated arms. A notch  9  is provided, approximately ¼ to ¾ inch from the end of rigid arm  8 . The notch  9  is preferably ⅛ to 3/16 inch wide by approximately ⅝ inch deep, and provides a means for securing the entire apparatus to, and carrying the apparatus by, an operator&#39;s belt or pants pocket when not in use, preferably on the back pocket out of the way when using a metal detector as shown in  FIGS. 3A-3B . 
     A grip comprising rubber, pipe insulation, foam, or similar padding is preferably provided around at least a portion of the brace  8  for comfortable gripping of the hand grip member by an operator. Openings  16  are provided in the stirrup  11  and brace  8  to couple them together via fasteners. Stirrup  11  includes an opening  14  for passing a portion of the user&#39;s hand through during operation of the apparatus  1  or brace  8  can have alternative filler piece  13  instead of the stirrup  11 . 
     In the preferred embodiment of the invention, the elongated arms  15 A,  15 B are constructed of ⅛″×¾″×¾″ aluminum angle. In a modified embodiment of the invention as shown in  FIG. 2B , the elongated arms  15 A,  15 B can be constructed of ½″ electrical metallic tubing (EMT), in which case it is advantageous to totally flatten short sections  151  of the tubing to facilitate attachment of the tubing with fasteners to an arm ring and a scoop member as shown in the  FIG. 2B . The tubing may be partially flattened near hand grip member. Drain openings  88  may be provided at the proximal end and distal end of the EMT to drain water and air there from when used in wet locations such as underwater or during scuba diving operations. 
     In operation, an operator inserts an arm through the arm ring and grasps the padded hand grip member with his hand, such that the forward end of the scoop member is facing forward of the operator. A metal detector may be arranged in the opposite hand and used to alert an operator to an area of media containing a metallic object of interest to be sifted from the media. 
     In a typical beachcombing operation, the (standing) operator draws the leading edge of the scoop member, through a medium that is to be sifted, in a forward and/or upward direction by moving his forearm forward and/or bending his elbow. The forward and/or upward motion of the leading edge of the scoop member causes the medium, that is to be sifted, to flow though the opening at the front of the scoop member and into the perforated basket. The apertures in the perforated basket are dimensional, located and shaped to facilitate and expedite the passage of the medium therethrough. During sifting operations, a portion of the medium is temporarily retained in scoop member and basket. An object of interest is simultaneously obstructed by the elements of the basket to impede passage of the object of interest therethrough. In this manner, the medium passes through the basket, while objects are located and separated from the medium. 
     It will be appreciated that the present invention is particularly useful when used in conjunction with a metal detector device. When the present invention is not in immediate use (e.g., when an operator is using a metal detector, but has not yet located a likely target portion of medium to be scooped and sifted), the apparatus can be conveniently hooked onto, and supported from, the operator&#39;s belt (or, alternatively, a pant&#39;s pocket when not in use, preferably on the back pocket out of the way when using a metal detector as shown in  FIGS. 3A-3B  to keep the device from interfering with a magnetic field generated by the metal detector for detecting metallic objects. 
     It will be appreciated from an understanding of the foregoing disclosure that the present invention provides a light-weight, ergonomic scooping and sifting device that can be operated by a person using only one arm and a hand. The interior surface of the arm ring provides a useful surface area against which the operator can apply a reactive force to counteract the coupling moment generated by the forward end of the scoop member as it passes through a granular medium. The closed geometry of the arm ring provides a useful means of generally restricting movement (and thereby facilitate easy handling) of the apparatus by the operator. The padded hand grip, being spaced apart from the arm ring provides mechanical advantage by which minimal movement of the operator&#39;s arm can cause multiplied movement of the apparatus scoop member. The apparatus is most useful when pulling the scoop towards the operator from a 2 o&#39;clock to 8 o&#39;clock position. 
     Since other modifications and changes varied to fit particular operating requirements and environments will be apparent to those skilled in the art, the invention is not considered limited to the example chosen for purposes of disclosure and covers all changes and modifications which do not constitute departures from the true spirit and scope of this invention. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed. 
     The length of the basket can be of different dimensions, with shorter dimensions generally being easier to move through media and longer dimensions facilitating rapid sifting of media. Preferably the basket will extend a minimum of 4 inches, but no more than 18 inches, beyond the rear end of the scoop member. 
     The cross brace appendages may be omitted, or it may alternatively extend to either side of the apparatus, or it may be constructed as an appendage of the brace. Various sizes, locations and shapes of the belt notch can be used, or, alternatively, the belt notch can be omitted. 
     A modified basket may be provided in which a rear portion of the basket angles (C) upwardly (relative to the forward portion of the basket and relative to the scoop bottom) within a range of substantially 0 to 45 degrees, in order to facilitate sifting when the forward apparatus is pulled forwardly and upwardly through a medium (i.e., sand). It has been found that increasing basket angle (C) and/or increasing handle plane angle (B) facilitates deeper scooping as opposed to shallow scooping of sand. 
     The forward edge of the scoop member may be beveled in order to facilitate ease of passage through the sifting medium. The bottom and sides of scoop member may be provided with perforations or apertures as shown in  FIG. 2E , preferably each no larger than the perforations or apertures in the basket, in order to facilitate passage of wet sand out of the device when used for underwater scooping and sifting operation. The basket shown in  FIG. 2E  includes a kicked up angle such that when the bottom of the scoop is arranged parallel to the medium to be sifted, the back end of the basket extends upward several inches. 
     Although at preferably 45 degrees, the angle (A) between the leading edge of the scoop member and vertical can vary from 0 degrees up to 60 degrees. 
     Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given. The weight of the device typically varies in a range of between substantially 2 pounds to in excess of 4 pounds. The various elongated arm supports or handles for the basket may include angle aluminum or tubing or shapes  4 A through  4 H. Openings may be provided in the tubing to drain air if the device is used in an underwater setting and to also drain water when used in a dryer environment. 
     The elongated support arms may comprise materials selected from a group consisting of aluminum, galvanized steel, plastic, fiberglass, copper, stainless steel, polycarbonates, wood, or steel.
