Anybody use a down-rigger (IntelliTroll) speed sensor for saltwater trolling? Depth Raider?
The last time I went trolling on somebody else's boat, we were fishing in heavy current off a point and even with large cannon balls we were running into trouble. It's amazing how far out the ball will swing in a heavy current considering the weight. The current on the surface of course was mild and the guy I was with was driving based on the surface currents while our bait was likely doing mach 9 down yonder as evidenced by the wire swung clear out. He wondered why we weren't having any luck. I did not wonder at all. Actually the only success we had was while turning around for obvious reasons (the bait finally slowed enough for the fish to do something about it).
I didn't know if there were "speed at depth" sensors for down-riggers then, but went home straightaway and looked them up. They're pricey, but I would wager worth the money.
Anyone on here use them and if so how has it changed your fishing, if at all?
