I have a tesoro vaquero. I have a question about the sensitivity setting. When I change the setting in air testing, it doesn't seem to make a significant change in target distance. But the more important question is, why wouldn't you leave it on the highest setting all the time?

sensitivity setting

If everything is right, no reason why you can't.. In some places, I get problems from computers, TV sets, and other electrical devices where I have to cut the sensitivity back to hear hits.over the noise....Some ground conditions, salt sand may also require you tune it down to find items..If conditions are perfect, FULL BORE ,go with everything you can crank.Let the machine lie to you..You know it can't find THAT coin that deep, but it did.,Cordially NAD
The key here is "maximum allowable" meaning the highest setting I can operate at w/o noise or chatter, and retain stability.
With some models you might reduce the Sensitivity a little if you're hunting close to metal poles, but I usually make use of a smaller search coil and coil position/sweep technique instead of reducing the Sensitivity (on most detector models).
There are times when I have to reduce the Sensitivity when working a salt water beach, but the first control to ensure is set right is the Ground Balance and the second one is Discrimination. Often, the 'noise' isn't really extraneous RF interference but a response to the very low conductive salts, and that calls for a little rejection (discrimination). You just have to be careful that you don't over-adjust for it.
So, 98% of the time, or more, I run with all the Sensitivity I possibly can.

I use just enough to keep it stable without to much instability. Although I have had times where I ran it way down, almost minimum and at times at minimum with small coils to get close to poles, metal fence, re bar, pipes, conduit, culverts, metal sheds, bleachers, baseball backstops etc. In RF situations. Just have to remember to work it back up when getting back out in the open more - I forgot to do that a couple times also:veryangry:
