Are some water detectors specifically tuned for underwater use?

[Right Brain]

I'll make the question a little clearer.

Are some water detectors specifically made for underwater use (wading), as opposed to some that might have the compromise of both wet sand and underwater use ?

I have had two, both Infinium and Excalibur are less efficient in salt water.

I would like to know if there is a detector that is specifically made for underwater in saltwater beaches , one which excels at that type of hunting more than on the wet sand/dry sand.

Being a newbie I am no expert but I will just say PI. I believe there are differences on some units and of course some are better but they are designed for salt water use and work.

The Whites Dual-Field definitely excels in the water.

Both the Infinium and the Excal are made for water hunting as are any that are waterproof... if you are looking for more depth then the Detector Pro Headhunter and Whites Dual Field are deeper than most water machines.

Yes, I'm looking for more depth, but under salt water only, as I couldn't give a stuff what's out on land (not for my next detector).

One of the most frustrating things in doing research on water detectors is that it's not often described how they perform in (noisy) salt water... depth wise. Just a few variables. Not surprised though, since it's hard to measure depth underwater.

Detector pro is out of the question.

So the Dual Field will go deeper than the Infinium in salt water? Won't surprise me if it does, from what I've been reading about it. At the moment it is likely my next detector, the Sea Hunter 2 is also in the running, but is slipping further behind.

Don't forget to look into the Tesoro Sand Shark, which punches just as deep as the Dual Field, and also has a lifetime warranty. It is rated to 200' in depth for SCUBA use.

Alot of people makes claims about the depths... in the water and its really not possible to tell for sure... but I have found some very old rings at incredible depths with my Dual Field... plus the DF pulse delay is set at 15uS which makes it very sensitive to small gold...

Becoming one with your machine and knowing where to hunt increases your chances over others...

How deep are you talking in the salt water and are you expecting disc? You will get great depth with the PI.... but its AM you get it all. VLF machines are difficult to tune to salt water... manual GB helps. If you are diving... you have the added problem of how deep is can the machine go. Fisher makes a pulse 8x for diving as well.... if you want to get off some big cash. Ive not heard much about it.... im assuming its because of the price. PIs are very reasonable as well price wise. I went with the Xcal.... BUT once its paid for its self ill be getting a PI as well. A lot will depend on how much digging you may have to do or WANT to do. Also what are you wanting to find? Im going to assume since you are talking salt water... jewelry and gold items..... make sure its tuned and will pick them up. Worst thing you can do is get a machine to do it all... just dont happen. There are trade offs on them all.

I want to go as deep as I can, but I know that if the detector doesn't solve certain salt water issues then it's no point talking about depth.

I have looked at the Sand Shark, it seems a neat little package but having such a fixed coil size doesn't do it for me, compared to having a 12" coil on the Dual Field, even though that's fixed as well, 12" is a size that I would want anyway. How do the manufacturers know that you don't want to go as deep as you can given the size of the target? Is a 10" coil going to get the most out of the detector, or is a 12" (8" inside) going to get the most out of the detector?

The targets that I'm after: Anything interesting, especially gold!

I like to detect in the water especially deep, it's peaceful, less people around you, calm and relaxing. Last time I went I forgot my waders (winter) and I had to hunt on the shore. It wasn't fun.

I have read that the true UW units (Like the JW Fisher Pulse units) are better suited to true UW use as opposed to wading. They use a different pulse delay and recovery. Works better for UW, but not as well for beach / surf hunting.

That's what I have read from those that know more than I.

[Right Brain]

The J W Fisher type diving units have a fairly high pulse delay and are more for treasure chest/car sized targets at ridiculous depths, according to what is said about them. Apparently for large coins it's ok but anything smaller, it's not. Though I haven't used them, just what research and hearsay says.

Exactly... they are looking for Cannons and things like that

Eric Foster was involved in the DF coil... its 12 inches overall with a 6 inch inner coil... its a excellent coil for small gold as well as deep heavier gold... I have been very successful with my DF as well as the PI PRO...


I don't do alot of hunting looking for fresh drops... most of my finds are older because I can pick up the deeper targets many of the other brands out there can't even hear... my hunting partner is the same with his Detector Pro Headhunter.. if you learn your machine you will be successful

[Right Brain]

Was Eric Foster only involved with the coil or the whole Dual Field?

I have looked into Eric's water machines, they seem to be very good and have a feature that I think would be very good for water PI's, and that's the Vsat adjustment type feature (can't remember what it's called on those machines). Unfortunately they're out of my price range

Anyone know if Eric has a website for his detectors? I remember seeing it a while ago, I can't find it.

Bill Crabtree used to be the seller of Erics machines but Bill retired.. I believe Eric has also stopped making his machines but you can find him over at Findmall here:
