Being the proud owner of an ACE 250,I too, am amazed at it's great signal response is various settings. There is a state park close to my residence and is the hunting grounds for many detectorists in the area. Due to fine weather conditions I was able to go there the week of Christmas and New Years. I covered the same grounds that myself and others hunted many times, The last day out I used only the pinpointing segment and was still finding clad, gold, and silver. That would be my main setting for searching except for one thing. With arthritis in my hands, it's very difficult to keep the pinpointing button pressed for a length of time. If GARRETT comes out with a mod on this unit with a pinpoint trigger, that would be my next purchase. GET DIRTY
