METHOD AND DEVICE FOR CONTROLLING WEIGHT

摘要

A method and a device for controlling a weight capable of rapidly lowering the weight without producing problems with line slack and others. In the method of controlling the lowering speed of the weight when the weight attached to a fishline is lowered from a sea level to a specified depth, the weight comprises a deceleration means for decelerating the lowering speed of the weight according to the reduction in speed when the weight is positioned at a depth corresponding to a speed reducing area when a change in the speed of the weight when the weight is lowered by its own weight is classified into a speed increasing area where the weight is thrown into the sea level, accelerated, and reaches the maximum speed, the speed reducing area where the speed of the weight is changed to be reduced after the speed increasing area, and a constant speed area where the speed of the weight is converged to an approximately specified value after the speed reducing area.
