Bounty Hunter brand is generally considered to be the low-budget spectrum of detectors. Ie.: you won't see many, or any, Aces out there using them. But with that said, it's also true that in the past 10 or 15 yrs, electronics, and the price thereof, have come down so much, that nowadays, even the cheapie machines can do thing that the machines of 25+ yrs. ago couldn't do.
Not sure of the particular BH machine you have, but it would find coins and items. Will it do it as deeply and accurately as the higher-priced top-brand machines? Probably not.
