Jeffhead,
I am not doubting your information on how far from the cable you can feel the induced voltage, just wondering where you get that from. I read about two of these studies that were conducted on positive ion attraction of fish, and one was conducted in a 10 by 10 tank the other in a 4 by 8 tank. That is why I came up with 10 feet. In fact one of the studies was actually conducted with catfish.

So this leads to an interesting question: Just how far from a downrigger cable can .6vdc be felt by a fish. Being that there is virtually no current involved here. Even if it were as much as 25 feet as DR suggests, you still basically need to find the fish first, and at that point nothing is more important (in my opinion) than presentation of your offering.

I don't disagree with anything posted here at all, just stating what I feel.
