Bounty Hunter

[PapaBear13]

Hello all,
Recently I had a few extra sheckles and decided to get a metal detector. I used to have a Bounty Hunter Quick Draw 2 and was fairly familiar with its controls, so I opted to get that one again. I got a really good deal on Amazon on it and recently it arrived and I was happy about that.
My only problem is that after viewing a bunch of YouTube videos about metal detecting and reading some posts here on this site, I kinda feel like I should have gotten something better. I suppose any metal detector is better than using a diving rod in a field (lol), but I am suffering from buyers remorse for no real reason.
So I have decided to just be happy with what I have for now and if I ever find some nice gold on the beach here on the Gulf in Florida, I can upgrade......but what too?? Thats my question. Whats a good one for when I am a ready to upgrade? I see some that look as if they are totally water proof (as in the control box can be submerged). Also, can I get a larger coil for my detector and will that really help me at all? Fill me in as Im a newbie.
Thanks to all for your input
