Just to satisfy my curiosity, I went out and bought a Garrett Ace 250. I know, it's blasphemy! I have read all the hype, and had to see for myself. It does seem to be a much more sensitive detector than my quickdraw II. I was digging everything, just to see. Kept digging tiny pieces of aluminum foil at 2-3" deep. I think it might be a deeper machine than my BH, and after getting used to it, I may like it more. For now, the BH isn't going on the auction block though. As redemption, I also purchased a discovery 2200, and it is supposed to be here today. The wife has started sticking quarters in the ground at the locations that she wants to plant flowers... oh well, it keeps me entertained!
