Hi all......I'm looking for a very easy to use, foldupable[sp], light weight, affordable, detector, with discrimination. I formerly had an oldy but goody Garrett, which was too large and heavy for me to handle for more than 1/2 hour, even with a shoulder strap, as I'm a retired lady. I'm thinking the 40 or 60 would be about perfect for my needs. Fl beaches, stash it in the camper van, help with rock hounding on occasion. I'd love to hear thoughts, from customers, not sellers of the product, as to how well they seem to do. I'm not comfortable digging in the water anyways, so the fact that it only holds up to 2' water depth isn't an issue for me. I could care less about the app thing, but fine that it comes with it. Has anyone bought these, and used them..pm me if you wish. Thanks, Joy
