Accidental Equinox sensitivity and update 2.0

[CarsonChris]

While doing update 2.0 I turned my sensitivity down to 8 since I was in the house. All excited to go test the Nox I drove to the closest beach. I forgot to readjust the sensitivity before I detected. So I’m thinking the new update lost depth. This beach gets pounded, by me, by other detectorists. Running with my sensitivity at 8 I found a clad quarter with a 1965 date down at 7”. I have gone over this area 20+ times but with that sensitivity at 8 I got a high tone squeak with a VDI at 40 and all depth bars illuminated. I’m thinking the quarter was on edge. I also found a 44 wheat penny that was just a whisper. With that sensitivity down I didn’t hear much noise below the coil. The coins would squeak and some would get an ID and some it was just the sound. Now I’m thinking I should use less sensitivity to see if I can hear the coins. Wondering if maxing out sensitivity highlights too much garbage and not enough coin?

I can see how it could possibly have that effect. However, I never "max" out the sensitivity, so I don't have that problem. If the junk is there, you're still gonna hear it.

I recommend lowering sensitivity all the time as another tool in the toolkit to help with unmasking (it is a tecnique that some call "sifting") in thick junk. But detectorists are obsessed with depth, so it runs counter to everything they have been taught regarding detecting. I like to go over a site at normal sensitivity 20 +/- 2) then hit it again at lower sensivity (12 - 15 or so) especially if there is a lot of iron. Single frequency at 10 khz (or 5 if EMI is not bad) seems to help with unmasking high conductors amongst thick non-ferrous trash such as aluminum.

I've done the same thing accidentally at 5 sensitivity and still found coins at 4-5 inches. Also had to rehunt that place when I figured out what I'd done. Found three more pennies around 8" at 22 sensitivity.

I am going to have to try this in the "pulltab patch" at one of the old parks I hunt. There has to be a pulltab in every square inch of a fairly small area(20x30'). I had written off the area, because it's been impossible to hunt. May have to give it another go...Thanks for the tip.
