Today I got a TRX from a fellow who bought it to replace his Garrett that died and decided he did not like it. I had already researched the TRX and decided it was the replacement for the F Pointer I got with my detector (free and worth every penny).

Here is my situation: When I turn it on the sensitivity is very high. It will detect a small key from over 5 inches. I finally figured out how to "ratchet" it down when it is indicating a target. I also found I can do it successive times to reduce the sensitivity.

Here is my question: Is there any way to turn down the sensitivity so it stays down, as I have to do a multiple "ratchet" every time I use it?
