The fishing rod involves a line (17) running through reel 1 (7), which is fixed through a hole to a metal support (8), and reel 2 (13), which connects to an inside metal weight (5) moving in proportion to the weight of the fish.The weight is also connected to a metal spring (15) via a wire (14). Attached to the spring is a needle (1) indicating the weight in kilogrammes on a scale (2). These are fixed to a metal bar (10) with supports (3,11). There are also screw holes (4,8,9,12) to attach to the fishing rod.
