Patent ID: 7121038

Claim:
A tickle stick for locating marine life underwater, comprising (a) a shaft having a first and a second end and a central axis running through the center of the shaft between said first and second ends and, (b) an articulated arm having a first and second end, and a central axis running between said first and said second end, said arm being attached to said first end of said shaft by way of a rotatable joint, said joint includes: a first hole in said first end of said shaft, a second hole in said second end of said articulated arm, and a pin extending through said first and second holes, whereby said articulated arm may rotate with respect to said shaft about said pin, said articulated arm includes detent means for moving said articulated arm through a series of holding positions with respect to said shaft, (c) a water tight compartment, said compartment being attached to said articulated arm, said compartment including a first and second end and a central axis running between said first and second end, said central axis running generally parallel to the central axis of said articulated arm with the first end of said compartment being positioned away from the first end of said shaft and said compartment including a removable lens at its first end to provide access to said compartment and to permit light to pass through said lens from said compartment to outside said compartment said compartment contains a volume sufficient to provide said tickle stick with a positive buoyancy, causing said tickle stick to float when released under water, said compartment accepting weights to make said tickle stick to have a negative buoyancy causing said tickle stick to remain underwater when released, (d) a flashlight having a light emitting end, said flashlight and light emitting end positioned in said compartment to direct the light from said flashlight out of said compartment through said lens, and (e) a motion sensor, a timer, a flasher and means for connecting said motion sensor to said timer and to said flash light to cause said flash light to flash on and off after a predetermined time of no motion determined by said timer and motion sensor to indicate the position of a tickle stick with negative buoyancy after release underwater.
