If you were going to buy an inexpensive (not cheap...but inexpensive) metal detector, that you could use on the beach and in a backyard or park, what would you get? I have looked at a new ace 250 (but I heard they take a dump over wet sand) and I have my eye on a used minelab xterra 30, but I am open to ideas. I am still going to purchase a minelab excal 2 for my primary detector (can that be used in a backyard as well? and how bout freshwater?) but I thought it might be nice to have a secondary for a friend or if I wanted to break it up and learn another machine for other uses. Im grateful for any comments you guys might have for me. Thanks again!
