Well finally getting back down to the beach this weekend. I'm looking for anyone that might have some advice about this area or beach searching in general, since I rarely get to go to the beach and take the MD. I'm trying to find a good way to waterproof my Ace 350, but not having too much luck. Not really interested in destroying my new MD, but I hear you can get pretty lucky in the water about chest deep. I was also thinking about putting my pin pointer in a bag, but that's not going to get me very deep. Any advice would be greatly appreciated.
I agree with @cudamark, if you're planning on going in the water and submerging your unit, make sure it's waterproof. Most everyone down here uses the Excal II or CZ-21 to give you an idea what works well. (Yes PI's like the Sand Shark and others work great too but you'll dig so many bobby pins that you'll lose a lot of time digging trash instead of searching). I think Myers Metal Detectors in Tampa rents units. There may be other places as well closer to the beach. You'll need a scoop too!
If you're going to work the dry sand, expect a ton of trash. Bobby pins, bottle caps, pull tabs, foil drink bags, etc. Yes, you may find clad and if lucky jewelry. Personally, I've had little luck in the dry sand along the towel line where people sit and hang out. Go early before everyone get there. It's easier to work and more respectful.
If you go in the water, shuffle your feet. It's still stingray season. Keep an eye out for the occasional jellyfish. You should not have other marine life to worry about if you're only going neck deep.
Personally, I don't worry about the tides. I go when I can. The height difference from low to high tide isn't that much in my opinion to worry about. I snorkel if I want to get deeper.
Other than that, work from ankle deep to neck deep. Try to dig everything that you're sure isn't iron. On great days you'll find a ring. On most days a little clad and costume jewelry. On all days strive to make it about the beautiful weather and environment rather than what you find.
Good luck and let us know how you do!
