ABSTRACT:
An improved weigh scale and fish landing device wherein the spring scale can be adjusted or zeroed in a tamper-proof manner. In one embodiment the fish landing device is a fish landing net having an elongate handle. The weigh scale includes a cylinder axially journalled on the handle with the handle extending completely through said cylinder. There is an annular chamber within the cylinder exteriorly of said handle with the annular chamber being closed at one end of said cylinder by a bearing end fixed to said cylinder and fitting closely about said handle while allowing free axial movement of said handle. A coil compression spring is positioned in said chamber about said handle and bearing at one end against said bearing end. A transverse pin is disposed slidably in said chamber extending from said handle and protruding therefrom, the other end of said coil spring bearing against said pin. There are weight calibrations visible on the cylinder adjacent said pin to indicate the weight of the fish when the net is in a lowered position. In a preferred manner one or more spacing elements are placed between the spring and the bearing end to provide the adjustment of the spring.
