Out today and noticed when putting Pro in pinpoint it seemed that the sensitivity was dropping . whilst I was holding down the button - so that I had to let go and re-press the button. Did a quick check - held coil still pressed PP button and sound and signal readout was dropping as I watched. Carried on but later I noticed it was the other way - press PP button and singnal just got higher and higher !!
I'm think oh no the PP ciruits gone unstable - back to the repair shop!!!
Well justin case I cleaned the coiland all sorted

.
Couldnt see anything but just wiping with my trusty leather gloves sorted it.
Question - has anyone had this?
Also, just a hint if somebody gets this - here is how to sort it....
CTX 3030 and Garrett Pro-Pointer. Garrett ACE 250 and AT PRO as spare.
