Black sand or mineralized ground... opinions please.

[ncclaymaker]

I need some opinions. I realize that black sands and mineralized ground can be the bane of some, but to others, pure heaven. I'm a fairly successful dredger that needs to easily and rapidly find hematite or magnetite in a practical manner without getting down and digging to much.


Requirements -

The MD needs to be somewhat water proof or highly water resistant, small head that is able to work in water, have digital output and speaker/headset jack.

Why spend time dredging up worthless sand, while a larger deposit may be yards away. This will help all of us prospectors do more with less. Please reply in the positive and negative about all brands that you've used. But remember, I'm NOT looking for gold with the MD, black sand will do.

Best regards and luck to all

Do I have this right... you want to know about MD's that can detect black sand?

Most single frequency VLF's will start to squawk in wet black sand and sometimes in the dry also. In the water, it might be a little trickier. Fresh water might react about the same way, but, in salt water, it would be hard to tell black sand falsing from salt water falsing.

if youre looking for black sand - i'll trade you for gold

I'm looking for wet or dry magnetite, hematite or an iron rich plume. Sometimes you can see the stuff right in view... other times the stuff is washed into the water with little trace. With a qualified ,metal detector I should be able to locate and trace the mineralization plume or deposit.

Hoping for advice on which brand or model would be best.

Thanks

If you want real Black sand use a Magnet , because all Black sand is not magnetic Black sand.Black sand on most beaches is sand that is Black not magnetic.Only a magnet can tell the differents

Black sand, magnetite or hematite or streaks of highly mineralized sand usually are "disliked" by the MD pros. But, to those of us the suck the gravel sand and gold from high river banks, streams, rivers etc., get really excited over the presence of the black, magnetic stuff. The dredgers heaven, MD'ers hell. When it exists in plumes, it can be plotted and marked, then dredged. This is the reason that I seek the help of the MD practitioners.

You ought to come to my house. The black sand in the creek is legendary. A lot of it is rutile and is not magnetic. Ten minutes of sluicing will get you several gallons of it. There is tiny gold here too. Metal detectors? Most any vlf machine can be set to find it.

Whites gmt has a black sand meter or something like that my buddy looks for the black sand and then the gold

You might want to look at the Aqua Survey Magnetic Locator.......check ebay for one. It is a compass that will tell you where the black sand deposits are when they are magnetic. There should be more info on them here on TNET. I have one but haven't been to the gold fields yet to try it out.
