See page 35 of V4.1 manual.
Alright
I will start here with info.
I will keep posting here in this post.
So those who want to read can follow along if they wish as I post info.
I will date my info here so folks can realize what have and haven't read.
Metals detecting testing is fun.
Can be challenging too.
Look
Outside temp 16F.
All my testing will be done, even comparing test between V4 and V4.1.
9" LF coil
Hot program
Sens 93
Reactivty 2.5, 3 and if needed 4.
Silencer -1
Freq will use 18khz and 8khz.
Audio response 5
Disc 0 full tones,
No notch or ground notch.

Today using 18khz only using version 4.1 just sweeping.
The following noted.
Field cleaner site.
4 ticks in mineralization meter when bobbing coil over clean ground.
Tracking GB used exclusively.
Sweeping coil using default ground sensitive setting (level 6) no top number in phase meter ever. Bottom number stayed at 88.
Bobbing coil would yield a ground phase number matching actual ground in both top and bottom of phase meter.
But after bobbing coil, sweeping GB phase of actual ground drops off. And 88 displayed-bottom number.
Lowering to 4 on ground sense setting. Even bobbing coil no numbers in either meter corresponding to actual ground.
Level 5 setting bobbing coil yielded actual,ground phase numbers in both meters.
Raising ground sens to 7, and sweeping coil,,actual ground phase info would come into both top and bottom meters, but would quite often drop out of top meter, making it blank.
Bottom number would hold, but every now and then go to 88, and with more sweeping would lock back to ground.
Raising to level 8, behavior similar to level 7 but unit would hold actual ground phase more often. Fewer moments of 88 readings with bottom number.
Raising to level 9, again better actual ground phase tracking.
Raising to level 10, here V4.1 seems to emulate what I am more accustomed to seeing with versions 3.2 and 4.0.
Detector keeps actual ground phase in window never ever drops out. (This statement here applies to clean ground only)
Now next I did a comparison with just monitoring noise as coil was swept. Compared ground sens levels 4 and 10.
Level 4 definitely quieter.
Remember this not talking here about how potential depth may be affected.
Folks reading here.
When weather permits, I will be doing depth comparisons while varying ground sens setting as well as comparing V4.1 with ground sens set to 10 vs Deus V4.
For the test comparing v4.1 with the different ground sens settings I will intentionally dial detector sensitivity down to where I get a weak signal with higher ground sens setting and then will start lowering.
Will try on buried 9" and 10" coins. Clad dime.
I may indeed have to run a higher Reactivty setting to compare some what I think are buried masked nonferrous, and smaller nonferous targets.
I will also do comparisons using identical manual GB too.
You will also see some comparison data done in higher mineralized soil, like 6 ticks in the mineral strength meter.
More data.
Same field as above.
Disclaimer: in some spots in this field I do get 5 ticks in mineral strength meter.
Still exclusively using 9" LF coil version 4.1.
Did a straight up comparison using actual phase attained using pumping GB dialing this value in using manual ground balance (phase 77 btw)
Sweeping over the patch of ground standing in the same place. Compared ground sensitivity settings levles 1, default setting 6 and 10. Level 1 the quietest, noise when sweeping elevated going to level 6, with even more noise elevation going to max level 10.
Next took a look at achieving bobbing GB while in GB tracking using freqs of 4, 8 and 18khz.
As I said before ground sensitivity set to level 4 in 18khz, no GB phase displayed bobbing coil in tracking GB.
Uaing 4 kHz and 8khz bobbing coil in tracking, GB achievable with ground sensitivity at level 2, with 8khz taking longer (more bobs) vs 4 kHz.
Should also comment here. I could hear feedback as coil was lowered (based on ground sensitivity setting) meaning I saw a pattern where I had a pretty good idea if a bobbing GB while in tracking GB was achievable.
More testing tomorrow hopefully.

Using Deus V4.1 9" LF coil
Comparing ground sensitivity settings of 1 and 10, airtest on clad dime, I see no real differences.
Only used 18khz to test, Reactivty 2.5, GB set to 90..
Compared level 1 and 10 ground sensitivity settings while holding detector pointed up at light wires and transformer, to see if Deus chatter or noise affected. No real differences noted.
Take a look at this pic. A nail and small piece of lead.
Using disc setting 2.5 full tones 18khz Reactivty 3, swing across nail and small piece of lead.
Detector ground balanced to steps phase 78.
Comparing ground sensitivity settings.
The lead object tonal presentation is more corrupt at ground sensitivity level 10. Tone is blurtier sounding and shorter, compared to lower ground sens settings, Level 1 provides a more robust, and more actual nonferrous pitched signal.
I do realize this is on top of the steps (ground) test, but I do think it sheds light here on application of ground sensitivity setting.
Doing this test and seeing (hearing) results, the small piece of lead, more odds of detecting with lower than max setting of ground sensitivity setting. I did keep my sweep speed consistent when comparing. Faster sweep speed although extremely small gives better detection here with lower ground sensitivity settings. This was a 2d dimensional test.
Another test, this time 3D.
2 nails above clad dime.
On the same set of steps with detector manually GB to steps.
Reactivty 3 18khz silencer -1, full tones.
I dialed disc to 4, this gets rid of nails when swept solo.
Sweeping the setup in pic, ground sensitivity level 10, a shorter tone, more blunt sounding, more easily confused with iron signal. Lower ground sensitvty setting tone gets more full, robust, longer, cleaner sounding on the edges. Again lower ground sens settings IMO allows faster sweep speed, coil movement and be alerted to suspect target.
More data
Deus V4.1 with 9" round HF coil
I took the detector for a spin in the same field as yesterday.
As far as ground balance tracking goes, very similar behavior to the 9" LF coil when sweeping.
One thing I did notice different vs the 9" LF coil.
The round HF coil will actually get a ground balance with tracking GB selected when bobbing coil with lower ground sensitivity levels selected.. But 54 kHz and 28.8 kHz.
Here might be the biggie though.
So far when testing the round HF coil, doing even the same 3D test above using the 2 nails and clad dime and some other 2d separation test with nails,,so far it seems ground sensitivity setting has NO effect. I listened close. Definitely not like the 9" LF coil here.
If I see some thing to reverse what I have said here on this I'll admit and post.
More data
Took the HF elliptical coil for a spin in same field V4.1.
It behaves similar as far as tracking GB goes as the rest of coils.
Ground sensitivity level 8 and higher would hold a good tracking GB, level 7 hit and miss, anything lower default to 88.
It like the round HF seems will achieve a gb when tracking GB is selected while bobbing coil allowing a lower ground sensitivity setting vs 9" LF coil.
And I also did a few separation and unmasking tests. It too mimmicks round HF coil, meaning ground sensitivity setting doesn't affect tonal signature unlike the the 9"LF coil.
I will definitely be watching this in the field.
The ground sensitivity setting does affect the way Deus tracks using both HF coils.
More data.
An actual head to head comparison using 2 completely differnent Deus units one V4.0 the other V4.1, both wearing 9" LF coils
Take a look at this pic, clad dime and nail
I booby trapped this nail and dime and used V4.1 Deus (ground sensitivity setting at 10) to rig to get just a flash of hit on the dime.
Settings used here on both detectors
Sens 93
Disc 2.5 full tones
Silencer -1
Reactivty 4
Ground balance manual 78
Audio response 5
Now the 4.0 coil was running at 17603 hz
The 4.1 coil was running at 17730hz
No hanky panky here, a fair test.
It has been said a ground sensitivity setting level V4.1 = 10 when compared to Deus V4.0.
Down the barrel sweep.
Disclaimer here: backphones wore on both detecrors, winds light.
Based on comparing using both detectors with the V 4.1 Deus set to 10 ground sensitivity it for all practical purposes mirrored the 4.0 version setup.
But here were the differences noted with changing ground sensitivity setting sweeping the same exact scenario.
Between ground sensitivity levels 5-7 the signal provided on V4.1 Deus better, more repetitive fuller sounding.
Lower than 5 really no signal at all.
IMO even dialing 4.1version to a level 9 setting beat the V4.0 version setup( remember no ground sensitivity setting on it)
Maybe this is a hint here with this test why default level ground sensivity is level 6 Deus V4.1.
