Hi Keppy!
Well, I'm a slow mover for sure, but I like to work areas that have a high trash content. What I've noticed about the Ace, is that the sweep speed has to be super slow, or the belltone is still ringing when I cross another target and it tends to confuse the machine. In all honesty I am trying to get a 4.5" coil and that will probably help quite a bit. Never used a Minelab, but the Bounty Hunters have a slow responce time too. The Ace is quicker than those for sure. I'm just too used to using Fishers, and am basing my opinions on that. The Fishers have a crisp tone and like a faster sweep than other brands. Honestly, I'm still trying to learn the quirks of the Ace. I still can't get over the heavy feel of it. There is a member who made a great looking cuff extension for the Ace, and I'm trying to get ahold of one. It's suppose to help balance it out better.
