Sensitivity vs. Depth? deep quarter example

[Knipper]

Finally got out with the SE. I kept the sensitivity on 'auto' set at a level of 25...very smooth tone. Just for fun, I tried the manual setting at the same level. Noticed a bit more "clutter" in the threshold, but not distracting. I got a deep, repeatable consistent signal and recovered a very deep clad quarter (which should have been a barber at that depth!!). Don't know how it got that deep, but it was in the side of the hole with just the rim showing at a measured 10". Before I removed it, I switched back over to auto and didn't pick up the quarter. I could still get the signal in manual, however.

Does anyone know just how far the auto sensitivity puts the machine below the stated setting to achieve stability? This could make a big difference in how I hunt. If the machine is constantly stabilizing the signal, I can't see why I shouldn't keep it at a setting of 32 all the time in auto.

Comments and observations welcome!

my opion is set it to manual at the highest setting to achieve stability...screw auto sens. and screw fast....deep on is the way to go....again just my opinion!

I wouldn't discount auto sensitivity. I use both and both seem to have their place and time. I've dug IHs at 10 inches before using 18 semi-auto. I've also ran into several instances where the audio sounded better in semi-auto than it did in manual sensitivity.
