Description

  The present invention relates to a position information measurement lure for measuring a submersion depth, a distance, and the like, and a lure position measurement method using the same.

  In recent years, many anglers have come to use various lures properly in Japan due to the increasing sport fishing using lures.

  Dividing the type of lure by specific gravity, it is roughly divided into top, floating, suspend and sinking, the top is a lure that does not sink, the floating is a lure that floats when stopped with buoyancy, and the suspend does not float when stopped A lure that stops in water without sinking, and a lure that sinks when stopped.

  In addition, lures are generally divided into shallow, middle divers, deep divers, etc., depending on the submarine layer. Shallows are generally submerged from the surface to about 1.5 m, and middle divers are usually submerged from about 2 to about 3 m. Yes, deep divers are submerged about 3.5 to 4 meters or more.

  The lure submergence depth described above is usually set by the length of the lip projecting from the front end of the lure body (body).

  In order to obtain good fishing results, it is necessary to accurately submerge the lure against the deep range of fish shadows where there are many target fish. Judging by the length as a main criterion, it is determined that a lure with a short lip is submerged in the shallow range, and as the lip becomes longer, it is determined that the lure is submerged in a deeper range.

  However, although each lure has a submerged depth that varies depending on the length of the lip, the shape of the lip, the shape or material of the lure body, etc. Since the standard dive depth is not displayed, the angler cannot know in advance the exact dive depth for each lure used in actual fishing, and as a result, the angler's own dive depth estimation There was a problem that a big difference was caused. In addition, it is difficult to accurately grasp the horizontal distance from the angler to the lure as well as the lure's submergence depth, so it is necessary to have enough skill to pass the lure in the range that the angler wants to aim at. It was actually necessary. Furthermore, in recent years, lures have been used because the movement of lures in water (tilt, vibration, etc.) has not been adequately quantified even though the manufacturers have made detailed designs. There is also a disadvantage that the angler who does not grasp the movement and behavior of the lure objectively.
