Do I have to bring a pulley to play with the gun shaft?

The length of (1) rod exceeds15m, which can be called gun rod. Choosing a rough fishing spot, first setting up the bracket, and then putting the gun pole on the shelf is also fishing. (2) Add a guide ring to the gun shaft of two or three sections, and add a reel at the position of two or three sections, which can hold at least 30-50 meters of fishing line, so that once there are big fish to feed, on the one hand, there is enough fishing line in the reel to release strength; On the other hand, once the big fish turn over and press down a lot by using the lever principle, it is easier to lift the big fish in the middle hook out of the water, and then collect them one by one until they can be copied into the net for protection;
