I currently have a white's prizm II and want to upgrade to a better MD. I want to be able to pick up deeper signals, and my main use is relic hunting and coin hunting. I have been looking at a Garrett AT Pro and wondered if anyone has any suggestions on this MD or another MD similar or better for the money. I appreciate all the help I can get as this will probably be my last MD purchase for a while. Thanks for all of your help and suggestions.
