Whites Prizm IV At The Beach Giving False Hits

[slider66]

I am new to metal detecting. I have been out to the Treasure Coast beaches 4 times now. I had success finding clad and that's about it so far. I will tell you I am already becoming addicted to it. Here is my question. My detector works fine in dry sand. That is where I have found the clad When I go near the water I seem to be getting false hits. Could it be that the water mixing with the sand is giving me the false hits. Do I need to make some setting changes to make it work better near the water? Thanks in advance.

The salt water over whelms a single freq. detector,not just the Prizm IV...very few will do good in wet salty sand or water.

Gary,
Thank you. I am here on the Treasure Coast. I am sitting here now looking for a better detector. What would you suggest for beach and water? I would not want to spend more that 900. Thanks

A nice used Minelab Xcal or a Fisher CZ21.... Tesoro make a great salt water machine too.
some say the Garrett AT-Pro does good in the salt water and some don`t

Did you want to buy NEW or USED?
Did you need it to be splash proof or water proof?

For our Atlantic beaches....
Minelab machines like the Excallibur, Safari, Explorer, and Sovereign are wonderful, pretty much self ground balancing and can be as simple as turn on and go. The excal is the only one that is waterproof through.

FISHER's CZ line of metal detectors are multiple frequency, and perfect for our Atlantic beaches. For around $800, the CZ-3d will work great and has an analog visual display, but it is not water or splash proof. The older model CZ-7, 7a, 7a pro, and 70 all have a digital visual display for target id, depth, and other controls; are splash proof and used models that are closet-queens can range from $250-425. The CZ 20 and 21 are the latest version of the CZ lineup and are waterproof to 200 or 250 feet, but no longer have the visual display. I just saw a CZ20 sell on ebay for $425, but typically they range from 700-1100.

Pulse Induction machines like the Sand Shark, Sea Hunter, and Surf PI are absolutely fantastic at avoiding false signals, however, the caveat is they are not effective at discrimination. Therefore, using them for anything but diving can be an exhausting chore of just digging trash.

I love my Sea Hunter in areas that are not trashy, and really enjoy my first generation CZ-7. If you're up near St. Augustine, you are welcome to give it a whirl. Meanwhile, I also know of a guy selling a pristine CZ-7a Pro for $350.
