Nokta Makro Gain & Threshold Settings


Recommended Posts

On the Anfibio Multi (and I think Kruzer & others) there is a definite step in sensitivity between 39&40 Gain and again between 69&70 Gain. Is this a change in the Internal Threshold? In a way this would be the inverse of the way the F75 adjusts sensitivity according to Mike Hillis.  Regardless, it is a very good set up in difficult sites. Most NM users know about the difference in response speed between 89 & 90 Gain on 3DI. This is different. I had read about these steps in a forum post that quoted Alper of NM. I can't seem to find that post now that I want to re read it.

I noticed the big jump in gain settings with performance and think they did it in blocks of 10 with very subtle changes between. I almost never run the machine past 89 here even in Gen Mode when I used to run that flat out trying to squeeze out an ID off a faint target.

I think the big jumps might be more Tx boosting along with over all gain adjustment. That seems to be my guess.

It would be nice to understand some of the underlying function. I know it is kind of getting into the weeds and many don't care to. I would like to see NM give more in depth operational discussion. A supplemental guide beyond the basics in the owner's manual. The detectors are so capable. I want to know how to run it at it's best. Perhaps Dilek will see this and chime in.

I wish NM would give us an app we could tweak the machines and even save out different configs that we could load up on a thumb drive and install on the machine. Dogodog and I asked and it fell on deaf ears lol.

I would just like to have something in print. A thread on Advanced NM operation on this forum that NM actively participated in would be great.

      THIS !! All the people boo hooing will be in line to get one at that price point. It will also force the hand of ML with their price structure. ML raised their price on the 800 and NM absolutely crushed that price point. The Legend doesn't have to be better, just equal to turn the fortunes in their favor. ML and their arrogant "obsolete" charge is foolish. Obsolete by definition means no longer produced or used. Many detectorist and their single frequency machines are still out there making great finds and having fun. Furthermore, single frequency detectors are still being made and sold. NM build quality is far and away superior to the Nox detectors.

      I thought I was pretty damn good, but this technology has me beat.

      Might be time to invest?

      Metal detectors often seem to have a 'Depth Gauge'.  How is it calculated? Is it the strength (or inverse of it) of the amplitude of the return signal?  So, for instance, everything else being equal, the 'deep' target would mean either a stronger target at greater depth or a weaker shallow target?

      While we're all abuzz with the announcement and advertised feature and performance characteristics of the XP Deus II, I'm wondering about tests that distinguish between detectors' target separation abilities.  'Word on the street' is that in trashy iron sites, the original Deus is still the best available.  Presumably those reports are based upon in-field testing, which of course is the real proof.  But the downside is, (AFAIK) these are qualitative observations, not quantitative.  Subjectivity involved?  Unfortunately, yes.
      We do have Monte's Nail Board Test for a special case -- iron nails near a single coin, all in the same plane and typically all on the surface of the ground.  Add depth combined with some mineralization (burying the MNB) and you've included another real world dimension.  But in the field, multiple nearby targets are seldom in the same plane.
      So you hopefully see the purpose of this post.  Has anyone seen/tried other methods to better simulate actual in-field conditions to differentiate between competing detectors to best be able to handle trashy sites?

      I mostly hunt in lakes and the bottoms are mostly all sand. A test on a sandy beach with the Equinox 800 and Xp Orx, both hit hard on a 14k 3.7 gram gold ring buried at 14". For mild ground I don't see a need for multi frequency. I do like the multiple frequencies on the Orx.
      Is there an advantage to multi frequency in mild ground?
