Black magnetic sand beach

[RelicMedic]

Just wondering if anyone knows which detector, if any, will work on a beach with magnetic black sand. The Nox goes nuts. We have a CTX, Etrac, Fisher Cz-21 and an excalibur II. Do you think any of those will work?

Probably not. The EQX is supposed to be better in heavy minerals than the other multi-freqs. Everything has its limits though. You probably have to go to a PI for a beach with heavy magnetic sands. Even that wont be a magic wand but it will be better if the pulse delay is correct (or adjustable).

You weren't able to get a stable run with lowering the sensitivity and using the Ground balance?

Not really. I dropped the sensitivity down to 15 and it helped a bit. Still alot of chatter and number going from the bottom to the top of the scale. Drove me nuts so I gave up. This beach, I know for certain has never been detected. It has got to be loaded!

Any chance it was EMI? Was the detector stable if you raised the coil?

Yes it stabilized once I lifted the coil from the sand.

[FONT=&quot][FONT=&quot]There is hope, but it isn’t in production (yet). The Fisher AQ can operate to full depth in black sand. Here’s a video I have linked to several places. It is about 5 years old and shows the at that time prototype of the Manta. This project was acquired and the staff hired by Fisher 2 years ago. A production version called the AQ is being worked on - but it’s not ready yet.[/FONT][/FONT]

you may probably try the EQX. that would be much better than others.

my PI Pro used to work great in black sand and my cz21 is not bad - dont know if is the same kind of "black sand" you are talkin bout though
these are some of my New england beaches

My Mirage Pi cuts thru the black sand without any problem.
Most VLF detectors I have tried on the beaches you and I have suffer from performance loss. Found using all metal mode helps but, drags all ID numbers downward and iron wraps around into the top silver ID numbers. Some targets that you would think were good were trash, targets thought to be trash were good.

The most confusing thing about "black sand" is that there are different types and each affects detectors differently. One can honestly say "my detector has no problem with black sand" but his beach is completely different from yours. If a multi-freq has trouble, everything will have trouble but the PI will be LESS affected.

HEY!!!! STOP THAT! I want at least a year without competition after its released, stop giving away my chickens before they've hatched.
