I ordered my MX 5 from KELLYCO. It was all about circumstances-my normal dealer for some reason didn't return my email and I had my account not go through on another detector brand. So, while waiting for clarification, I reread Monte's posts on the mx5 and since I didn't have a machine with adjustable g/b I just said to myself "Why not get the best I can afford without throwing my money away?" I'm not too crazy about EXTREME depth but do want the features.I was once a White's user and also used to order all my detectors from KELLYC0-so now I guess I'm back home!
