Thanks coinshooter and RCSnake for the input. I sometimes do the first method (oops forgot about that) and I can say NOT ONCE has my GB been off in that way. I admit I have to do it more often but I had been doing it 2 or more times or so a hunt up until a few hunts ago with perfect results. Guess with it always having a good GB I have been spacing it lately.
I'll start doing it more often!
Coinshooter - The strange thing with Martin's GB test is that he picked up the coin better at 8! That is why I thought he must have essentially had his GB + offset enough to make it more sensitive to the coin. I thought then comparing it to a regular offset would have proven this...
Thx,
