Completely new to metal detecting...... a friend of mine gave me his Bounty Hunter Pioneer 505 ..........I was just wondering if this is a capable metal detector for the beach?........ and how hard is it to use? it sounds off with a lot of Bells, whistles, buzzes & clicks when I turn it on........ it never seems to really settle down....., it's been sitting up in his garage for years unused......... Don't know how to tell if it's ok Many thanks for advice
