I gust got a IDX pro A few mths ago for $350. I love the weight and real easy to use Ive been finding coins 8" deep. The most Ive found was using a whites 4900 (newer black box) . It is really sensitive it found the smallest ear rings. I regret selling it. Then i used the 6000 Di pro sl for about 5 years,just to heavy for long hunts. I plan to get a Mr Bills upgrade for this IDX pro unit. So far i ve been happy with it. I have not tried it a the beach yet.
