Lower Number of Tones= More Depth?

No work today as we've received 22in of snow. So, by lunch I had a question. Does the number of tone choices affect the depth...does the new EQX get the same depth across the tone number choices within Park 1 and 2 (and all-metal)?


The sens was 21 and the recovery was 3.
I air tested a KG2, Rosie, 3 cm dandy button, and a 1909 IH. The average depth in inches of all these items is listed.


My findings-


Park1, 2 tones- 12.5(inch average)
Park1, 5 tones- 11.4




Park2, 2 tones- 12.3
Park2, 5 tones- 11.8


All Metal, 2 tones- 12.3
5 tones- 12.3

Seems the 2 tones gets more depth than 5 tones. Is this a thing? Does this happen across all detectors? I always used 2+ tones on the T2 as it gives the shape and size of the objects, but I didn't know it gave more depth.
 
By your testing, it would look like the less tones the more depth. I've noticed something similar on my CTX, though I never tested it. But from experience, I had tried getting to know the 50 tone setting and it just seemed like the deeper and iffy signals were much more pronounced with a 4 tone setting. My only way to explain it is that the processor takes more power to categorize the signal into many possible bins than only a couple, so has a possibility of missing weaker signals.
 
Well that seems kinda weird but maybe your tests are accurate. I prefer 50 tones so I hope that is not the case. I have had the Equinox for almost a week and have not used it yet except a few times in my test garden...weather has not be pretty here. But at least we do not have 2 feet of snow...feel sorry for those of you dealing with that mess!
 
I did a re-test, only this time I added 50 tones, and I performed it in a sterile, sound proof lab :lol: Well, next to my furnace in the basement. I averaged the same four targets.

Park1
2 tones- 12.4
5 tones- 11.9
50 tones-12.4

Park2
2 tones- 12.6
5 tones- 12.4
50 tones-12.6
 
Crunching the numbers Drew, I ran a standard deviation on the geometric mean of both sets of data. I then doubled the sum and derived the square root using the negative log function. The result is a median of 0.1758 inches. This is statistically negligible when you factor in the covariance using even-biased rounding with two significant figures. ;)

Yeah, what HE said! :shocked01:..... :rofl:
 
:lol:
So, I'm guessing the MDing community has already figured out there isn't much difference in depth between the number of tones???
 
The depth of the modes (park 1,2, farm 1,2, etc) are really related to the recovery presets for that mode. Higher recovery = less depth. If you adjust the recovery and sensitivity to the same settings, it's almost exactly the same depth for any mode.

Hope that helps!
 
I used recovery 3 in all modes... I guess there isn't differences when changing tone numbers within the same mode.

Of course my math is suspect. But I agree with Ken. Recovery speed probably has more impact on depth than any other setting. Next time you get a good faint deep target using a low recovery speed, raise the recovery speed and watch that faint target disappear.
 
I knew about recovery speed and regularly change it when the situation warrants...but my question was if the tone-numbers had anything to do with depth?...and the answer seems to be no. Thanks for your help guys!

I also have my "Testing lab" in the basement next to the furnace. I actually use one of those plastic folding tables that I used a sharpie to mark off inches on the end of for coil testing. My wife was hardly perturbed with me.:hystericallaugh:
