Black Box
I've always wondered if my boat was "hot" or not...
I finaly bought one and hooked it up. I was surprised to find that I was way off the range that is desirable for attracting fish (.650)
There are so many variables with grounded equipment and just having a trolling motor in the water without grounding makes a difference.
I know that there are a lot of you out there that say "so what" because you are trolling 100' or more behind your weight. Obviously it doesn't make much difference back there, but I like to troll closer so I can make sharper turns.
Besides, if it helps, why not attract fish??
I've heard stories back and forth on the subject, and don't really know if they work or not, but I'm glad I got mine and I know instantly what I'm putting out and can adjust it accordingly.
