Anyone ever slap a Bigfoot coil on a modified IDX Pro detector? I was wondering about compatibility first of all. I assume that the same frequency of my other 6.5 detectors is all that is needed. Secondly, I was wondering the procedure for ground balancing. And last I assume I would get better results in the wet sand. True or not? The reason I'm asking is that I just purchased a modified IDX Pro. When it arrives I was going to slap some coils on it and play around in my yard.
