Don't feel bad about the BH, I bought one and just upgraded to an AC250 and waiting for a Tesoro Vaquero to be shipped to me. It wasn't that the BH was bad because me and my son in law both had one; it's that I got the bug for more, but believe me, in the short time I had my BH we found a lot. I really wanted something to get a little closer to the surf and my BH would pick up a lot of false targets because of all the minerals. On the dry sand it did fine.
Use it , don't feel bad and when you are ready to upgrade, do it.
