Nokta Legend V1.11 Depth


Recommended Posts


I was able to do a second quick hunt today. I was willing to dig absolutely anything with a decent repeatable signal and with stable target IDs. I was at an elementary school that has thick sod with sod staples about 4" below the surface that are in various states of rust. Makes for a very noisy, iron false filled hunt but at least the staples are spaced regularly so I basically know when I am over one. Some of these targets were in the sod thatch so around 3 to 4" from the bottom of the coil. Others were well below the sod in the original soil. The grass was about 4" long and very thick so some of these targets were detected about 8" deep. None had weak audio responses or unstable target IDs once I had the coil properly centered over them. Like I said, I was searching for low, mid and high conductors including gold jewerly (skunked) and silver jewerly (got one .925 ring) and silver coins (skunked but I did get a Wheat penny). I was running the same settings as in the previous post. The Legend's iron mineralization meter showed 7 or 10 bars filled. Ground balance stabilized at 5.

Thank you for the thorough and objective experiment Jeff. You're one of the very few hunters that I trust for such experiments. 

I don't want to derail your thread, but as a side note to depth, Dilek recently stated that their head engineer has been working on a "boost" mode for the Legend, and that it will be an enhancement update.

However, lots of posters from around the world are doing just fine with their Legends, even with the latest software V1.11

Yeah, no depth issues here with the Legend running v1.11. Granted, I'm dealing with a fairly low level of ground mineralization, which makes things much easier.

Thanks for the thorough test and post, Jeff!

I am aware of the announced version 2.0 software update which includes an M4 Beast or boost mode. Whether that has anything to do with some of these current complaints is doubtful. 
 

Several previous Nokta Makro detectors had “Boost” modes. In general they were effective in certain circumstances that were not hindered by high EMI or high mineralization. I did not get to use them much.

No depth issues for me either. I also have low level mineralization. I'm also getting a little more depth and better ID's with the appropriate SMF modes compared to the appropriate SF modes. My tests are always with a silver dime and gold ring.

Jeff,

I was wondering the same about the boost mode. More specifically, the Legend already has a very high sensitivity ceiling, so any more will be an issue in EMI. However, perhaps the boost mode will mitigate EMI by increasing the Tx power and utilizing some sort of digital signal processing. Well, it will be an interesting enhancement none-the-less.

I broke down and bought a Legend about a month or so ago. Watched lots of videos and read lots of forum posts before I ever went out in the field to hunt with it so I could understand the settings. I'm not seeing depth issues in my high mineralized soil or beach hunting. I don't think it's as deep as either the Deus 2 or Manticore, but it's no slouch either. I found targets over 12 inches deep at the beach and over 7 inches deep at park. No performance complaints here.

A good thorough performance report in real world conditions. Thank you for posting it to help clear the fog some people insist on remaining in.

Jeff,

Always love your write ups.  I'm curious about a couple of things:

  1.  Why don't you run any bottle cap rejection?  I will be honest, I have played with my Legend and the bottle cap rejection really doesn't do much so I keep it low.
  2. "When I switched to the F (ferrous rejected) discrimination pattern along with having the iron filter setting on default 8, the 3 flagged targets that were copper and silver basically disappeared. "  Do you think if you ran in F and lowered the iron filter to a lower value you would have hit those targets?

I only run the Legend bottle cap rejection when I have to.  Bottle caps are not a predominant target at the test location. 
 

Due to the high iron mineralization in the area, the Legend, Equinox 800 and Deus 2 all detect deeper non-ferrous targets with some intermittent ferrous responses. Running the Legend with the F discrimination pattern would cause broken up, sporadic responses on those nonferrous targets.
