I'm going to test out a friends compadre tomorrow, see if I like it, and maybe get one for myself. I was wondering, what level of discrim I should set it on that would be best for coin shooting? Also, how deep can I expect to pick up coins with it? I'm used to a simple beep-beep machine, I have a cheaper Bounty Hunter, so I imagine it won't be too much different. But, I have been told that the tesoro's are a bit better in the depth department. Any help would be appreciated, thanks!
