Hi,
I use a manual downrigger and I have the same idea of using the shuttle hawk to avoid raising and lowering the ball after every strike. The difficulty I experienced is that when the shuttle hawk is descending with the fishing line, the drag from water also pull the fishing line away from the downrigger cable. I cannot tell if the fishing line is being pulled out by the water or by the shuttle hawk. If I try tightening the line, it feels like I could be pulling up shuttle hawk as well. So at the end, I have no idea the depth of the shuttle hawk. I wonder if anyone has some insight as how to use it to have the confidence that the shuttle hawk is indeed at the depth you like it to stop. Thank you, Joe.
