This post is a good

I've only been here for roughly a week. Like many I always thought about MD as something to fill my time.
I live in South Florida and had thought about the Garrett's, since they are fully submersible. Well turns out
(yesterday) my boat became a sub. It's an inflatable (bottom too) the keel tore away from the tubes just
under the bow. Hopefully repairable.
Anyhow...What is the BEST detector under say $800 for the surf, beach and underwater of a max 10 feet.
I was sold on the Garrett. But I got to thinking I have a Garrett at my disposal whenever I need it.
So for SHALLOW surf, beach and the local parks. What is a good choice?
I've read so much I'm just overwhelmed now.
