I am currently carrying out some experimental mods on a SD2100 and SD2200.
There are some common ground between these and the SD2000. One area that can be improved it the resistive losses in the input switching, this could also include the GP-X series of detectors but I am not 100% sure. Maybe we could bribe Zed to do a circuit of the GP3000?

One thing that I have found is that by changing the time constants in CH1 and CH2 against the ground balance channel makes for a much cleared signal. I still am of the opinion that the SD2000 is the best detector that M/L have released for serious Gold prospecting, the newer offerings do not match it for detecting deep Gold.]]>GPM - DAE ModSun, 06 Apr 2008 19:28:12 +0800Help with gpm diy mod on sd2100e - by: Sandstorm

I stripped the paint off all the resistors in the same area as on the 2000 and found the two 47k resistors, will soon perform the mod once the components arrive ☺]]>GPM - DAE ModMon, 03 Sep 2018 16:15:46 +0800Help with gpm diy mod on sd2100 - by: Sandstorm
