My nox 600 arrived 2 weeks ago and I have been putting it to work. For me it has some drawbacks but the good outweighs the bad. I still need a lot more time with this detector. My Nokta Fors Core and I were "in tune" with each other.
I run the Nox on park 2, multi, 20-21 sens, 8 disc, 1 iron bias, recovery speed 1 or 2. Anytime I see a vdi of 20-34, even if its super jumpy and bouncing out of that range I dig it. 35+ has been iron or oddly enough hot rocks so I Ignore those. 12-19 is where most of the targets sit, often jumpy as all get out. I have been digging all these targets but have yet to see a pattern of good target/bad target.
I have been avoiding 8 - 11 vdi. From those of you with nox experience, when do you dig?
Your decision to dig, maybe should be situational.
Virgin sites, dig the more solid, as targets get fewer and fewer lower your threshold for digging.
Detecting site history. What has been pulled out before. How old is site.
On solo sitting real deep nonferous high conducrive coins, Equinox can read lower, these signals usually real coil position sensitive, and you may not get tone on every sweep. Once alerted to begin with, better coil management sweep height and seeped, and location needed to gather better intel.
You can try and dig say targets that tend to read 19 plus on meter. Some fluctuation will generally be witnessed though id wise.
Speed setting. Speed 3 on your unit is a good speed to use to get accustomed to unit.
Sens between 20 and 24.
Don’t sweep too slow if area is more open. Nice brisk sweep.
You’ll gather intel on target’s size by using horseshoe button. Audio squeal on bigger items usually.
Signals reading in the mid teens can be looked at with single frequency 5 kHz, if these mid teen reading targets jump to high 20s to in the 30s, good clues pf bottle cap. Can be deeper too.
Repeatability of signal as well as repeatability of how ID is displayed, even if it windshield wipes a bit- good clues to determine how worthy a targrt. Iron likes to really vary when comparing sweeps, even after you really control your sweep, coil height and position.
Nickels can read 10-14, with biggest number reading 11-13. Deeper nickels can read lower than 10 too.
Gold, can come in really anywhere, good range 07- 19,with some bigger rings reading a bit higher like 20-22.
Equinox will jump on lower conductor and mid conductor signal,wise better than high conductor. Assuming similar size and depth.
Equinox can give signals with more coil height above ground on lower conductors vs higher.
Running 50 does give me more intel sometimes vs running 5 tones.
Spend time with your detector. It will come to you.
Try and learn to determine how challenged a nonferous targrt actually is, by using sweep speed variation, horseshoe button, coil height-especially in areas already hunted hard that contain modern trash.
