Hi folks, wasn't sure where to post this as I see there is no Musketeer section on the forum. I just got a new in the box Minelab Musketeer Colt. I have been detecting for many years swinging mainly Tesoro detectors, I normally like tot lot type hunting for jewelry & clad but thought that I would let the tot lots refill and try for a few older deeper coins, that's why I got the Colt. I am having good luck with the Colt, digging coins from the same places I have hunted many times. The Colt is deeper than the Tesoro's I have owned but think it isn't at its full potential. Here is where I need you folks help - most every Tesoro I have ever had (there's been alot of them) chirped when the sensitivity is turned to max which tells me that they are putting out full power. When I turn my Colt sensitivity to max it is completely quiet, not a chirp. Maybe they are suppose to be like this I don't know as Minelab is new to me. Another thing I am thinking is the Colt's ground balance is set alittle too positive for my ground, because when in all metal mode if I drop the coil towards the ground I get a pretty good beep. I know with the Tesoro's there is internal pots. to adjust the ground balance,etc. I have read that on the lower end Minelabs such as the Colt the pots. are labeled, I haven't opened up the control box as I don't want to screw anything up or void my warranty. I see two screws on the control box - one on each side of the coil connector jack. I was wondering if I took out the screws if the control panel would come out of the housing so I could find the pots. Do you think that I would get alittle better performance/depth if I figured out how to get the sens. so it chirps at full sens. and get the ground balance set for my area. Like I mentioned the Colt is working very well and am really happy with it but would like it at is full potential. Thanks all. Steve.
