Get a sand scoop or lightweight shovel. Consider (and potentially practice) the idea that when you find something in sand, you simply remove the sand from the location and re-sweep the whole to see if it's still there. If the beep is still in the hole, you missed the target. If not, you pulled out out in the shovel. Then dump the shovel and spread it out with your foot.
It's VERY fast to recover targets this way in sand. Hold you detector in your swing hand, and your shovel in your other. Swing, beep, dig, test the hole, swipe the sand, swing beep, repeat.
A sand scoop is nice, but ultimately the swipe it with your foot method works just fine, too.
Fill in your holes, and DRAG your shovel if you want a ready made trail to see where you've been!
With the ACE250 you'll need to stay in the dry sand, but you can definitely discriminate out iron. catch the edge of bottle caps to hear the "grunt" assosciated with them to rule them out, or just dig it all. It's fast enough it really doesn't pay to check objects from many angles, and try to determine what it is first. Just hit the beep, scoop it out, swipe your foot, find the object, use your foot to scoop the sand back in and keep on truckin!
Cheers!
