Default Guide to selecting a Salt-beach / Salt-water Detector

Having trouble using your detector at the beach? Read this...

Since the 1960's, enthusiasts have learned to make adjustments to single-frequency VLF detectors to find targets at salt water beaches. Newer machines may even have special software programs to help compensate for salt water, but often times these adjustments lose depth and/or sensitivity to small targets, give random erroneous signals, and eminate noisy chatter. For those of you plagued with these results, a great alternative is upgrading to a multi-frequency or pulse induction machine.

Multi-frequency detectors will compensate for the conductive salt and mineralization, and usually without losing depth and sensitivity. Further benefits of M/F detecdtors include typically running quiet and giving an honest signal, e.g., if it beeps, there is a real target. M/F detectors consequently cost more than most S/F detector and that price increases if you want them waterproof. Perhaps the key benefit of a M/F detector is it can discriminate unwanted targets like iron. This means you can cherry pick targets and make the most use of limited time.

PI or pulse induction detectors are the cost efficient alternative to MF detectors. They work great in salt water, but the caveat is they do not discriminate (well).

The following chart provides a list of the major manufactures of MF and PI detectors. You can use this list to narrow your selection of a competent salt-water detector. Also be sure to contact our forum sponsors (dealers) for the best price and availability!

Happy Hunting! -David

Original thread had replys to suggestions. They've been added and the post was replaced with Metal Detecting Memes. Enjoy!

David, for what it is worth, the CZ-20 does have led lights that glow when you are over a target that isn't discriminated out.

Nice chart

That's some really excellent info! Thanks for creating this! I ended up making something similar for my personal use when I was researching potential upgrades.

How about including DetectorPro's Underwater and Pirate/PiratePro detectors. I think they are the models DetectorPro is currently selling, and they are VLFs. I saw a couple detector comparison videos of the Underwater model being used it salt water conditions and it seemed quite good for it.

Also, perhaps adding a data field for price range would be good? Most of the time when one is looking for this sort of info one is interested in first-time-buying or upgrading and in either case price range is a pretty important factor.

Anyhow, thanks for posting this! I'd say once you've perfected it you should probably get it stickyed up at the top. That way when this section gets the inevitable- 'looking for a salt water machine- what should I get?' questions, they can refer to your chart easily.

Too many discontinued detectors on that list, but really good effort!

I agree! Manufactures have discontinued some really great salt water beach machines!!

Look at those rig prices! Huge financial 'Barrier of Entry' into Beach/Water Hunting! Add a scoop and other gear, and Man!...The ROI potential is miniscule! Add tanks and a compressor like Scubadee? Oh boy! He will be in debt for years to come!

Great chart there Dave! Hopefully others will take note of the financials and not even bother to attempt this!!!

It has been a while since my last update. Garrett, White's and Fisher (First Texas) are yet to release anything new for salt-water hunters. Meanwhile, many people continue to wait for their NOX to arrive...

So, time for some updated memes.

The earlier production models of the cz -21 did have lights, they leaked. You still see them occasionally.

This thread is averaging 1,000+ views a month!!!
.
May 2018 UPDATE:
Minelab is still struggling to satisfy orders and fulfill demand for their new machine. Meanwhile, Tesoro, Fisher, Garrett, and Whites continue with their cutting-edge, 10 and 20 year old technology. <-- Big "eyeroll" on that statement. Don't get me wrong, it works ...just like a Model-T, but you don't see Ford still making tin-lizzies either.

Nokta, XP and Makro seem to be responsive to customer suggestions and quickly making advancements. We are hopeful but none have yet produced a machine that operates with more than 1-frequency at a time.

Regardless of what you swing, it's time to enjoy some new funnies... H/H y'all!

UPDATES:
  • Minelab is finally catching up on their Equinox backorders. Seems like another competent beach machine
  • Minelab is now offering waterproof phones for the NOX series
  • Minelab hasn't shared a release date for aftermarket NOX coils, but they should be in the works.
  • Fisher Labs / First Texas is leaking rumors about a new PI machine aimed @ beachhunting.
  • Several eastern European based manufacturers are advertising MF-VLF bluetooth coil machines that utilize your personal smartphone. Keep an eye out for these to come to market.

These are not included because they are single frequency VLF detectors. As such, they work great on dry sand, but on wet sand or submergered they have excessive chatter, false, and require diminished sensitivity in order to cope with the conditions. FYI - these were first hand results from myself and two forum members that used a tuned-diver, stock wader, and (2) new PP w/ NEL coil machines.

.
Due to PMs about detectors not listed on the spreadsheet, here is a quick update about...
.
Why your metal detector is NOT on the list:

1.) Your detector is NEW and is now listed on an updated post with a revised spreadsheet. Check on a more recent post on a different page. Perhaps page 2, 3, 4, 5....

2.) Some detectors have boxes with beach pictures and lofty claims but it is simply fancy advertising. It doesn't change the fact that it is still a single-frequency machine.
Examples: AT-Pro, DP-Underwater, Racer 2, etc

3.) Some detectors have selectable frequencies; however, they can only use one of them at a time. This means in salt water they still function like SF-VLFs which typically chatter or require adjustments such as reduced sensitivity to stop falsing.
Examples: Deus and Multi-Kruzer
