Nfd 90 Metal Detector

[Sven1]

Latest metal detector to try out. Experimental unit out of the Ukraine made by Alex. I mounted the control box on a White's s-handle, Fisher armrest and Fisher lower tall man's rod. Very light weight. My unit is set up a little hotter. Hopefully the weather will cooperate Saturday for a field test.

Frequency at 90kHz, nice.  What's it's intended purpose?    Sounds like its design is to pick good targets out of trash

I think these videos will give you an idea as to its potential.

My main use with the 9" coil is magnetic black sand mixed with dirt soils.

Looking for coins and jewelry within the first 7" of the surface. While ignoring iron trash.

Might just make for a great Competition Hunt machine.

Bench testing, proves to be a very interesting detector. Very respectable air test depth.

Single 10 turn tuning-threshold-sensitivity control. No-motion and motion toggle switch.

LED bar graph that helps with ground tuning.

Threshold super stable like the vintage Garrett Master Hunter 5khz in all metal mode.

You can hear the slightest target threshold change.

Loves all non-ferrous targets.

Think it could work well in iron nail trash areas picking out the good targets.

Like some detectors in all metal mode, no disc, might be a challenge in modern trash and foil littered areas.

Appears easy to size a target and to pinpoint. Audio volume of the  target found gives indication of depth and size.

The NFD90 shares roots with many vintage and modern machines, combining them into one  basic work horse machine.

If you have been hunting with detectors since the 1960's, it will give you a familar feeling. Just feels part VLF, TR, BFO, Pi wrapped into one. 

==========================================================

Carl Moreland is having one made for him, should be arriving in a few weeks.

Either the manufacturer or a manufacturer representative has already been on the forum promoting the product.

Yeah, high frequency detectors air test great. I used to do all these surface test tricks with the Gold Bug 2 also but things change fast when you add dirt, and especially moisture. Be sure and throw flat steel into the test, not just nails.

I'm not obligated in posting positive reviews. The unit was not free, four of us did have to pay for the units, the price was right and for a worthwhile cause. The NFD 90 will be probably be a niche detector and not suited for the masses. It's something a bit different for those who want to get back to basics. Will be interesting to see how it performs.

Love to see how it works in the real world. I wouldn't go head to head with an Orx with 9"hf as that coil is iron blind.

Would like to see how it handles coal/coke, iron rich grounds and black sand.

Does he have a USA distributor?

He is an independent electronics engineer who has been in the hobby a long time.

If you can cut Black Sand....I am interested!!  Not sure how 90khz will be able to do that? 

[Sven1]

On the bench, my vial of black magnetic sand will cause the detectors threshold to null and not pick up gold jewelry etc. that can't break the threshold null. If I tune to the vial of black sand and hold the vial under the coil, pass a gold ring coin etc. under the coil, the NFD 90 has no problem punching thru the black sand and getting a positive target response.

Note this is on the bench--testing. Not real world test.
