I will tell you i just got an atpro and love it. It is waterproof up to ten feet, and seriously gets great depth and separates trash pretty well too. Now i only have experience with one other detector, but i love the atpro so far. Another one to look at would be the whites mxtpro, but is about 200 more, and not waterproof. I know the mxt has a gold prospecting mode, and i have read that it does pretty good for not being a full gold detector. The atpro is very light, and some people complain about the weight of whites detectors, but i guess that depends on your physical ability.
