I used mine for the first time last Sunday, my buddy uses a minelab explorer 2 so before I dug any targets I had him scan the target also just as a comparison, and I scanned his also just for comparison, and we found the mx5 to be more accurate than the explorer, I found a Morgan which rang up in the silver dollar range, his rang up it as a junk signal and he said he wouldn't have dug it, he found a walking liberty half which rang up on mine at 89 to 91 which is dead on and it rang up as a dime on his. The mx5 is a bit more chatty than I'm used to but dang I can used to that, I ran threshold around 5 and sensitivity two notches below max and the machine was happy to do it, a very easy machine to run hot, especially once you get the threshold right, I love this machine already, nickels rang up between 18 and 20 on all three of the ones I found. Awesome machine first time out, can't imagine how awesome it will be once I've learned it really well
