Very nice work you could have a nice business of repairing metal detects

Umm did he ask you to do that? Reason is I am conflicted, my boys always "Moded" stuff of mine and made it useless....But I sure wish my kid would would mod the stuff I want them to......LOL
Seriously,
Great job, looks great.....start a part time business.

Really nice job!
Still getting PM's about this mod so I figured I would put the instructions I followed in here for everyone else. This is from another forum and was a thread started by MR. Bill.:
Seeing that I have got out of the metal detecting busness. I thought I would pass this on to you all.
Be very carefull unsoldering the componets. Distroying the circuit traces is very easy to do.
Remove VR1 Trimmer off the board. Replace with a 50k linear taper, single turn potentiometer.
Remove VR4 trimmer off the board replacing it with a 100k linear taper, single turn potentiometer.
Mount these potentiometer’s externally on the top of the case.
Replace resistor R24 with a 2.2 Meg. You could have either a 470k or a 1.5 Meg there depending on when the unit was manufactured.
Check resistor R7. If it’s not a 51 ohm resistor, replace it with one of that value. It’s most likely a 100 ohm from factory. Later manufactured units had 51 ohms.
For potentiometer wiring, I use flat multi wire such as type used in computers for component connection to the board. I cut a 2 wire, 7.5” piece for the 50k ground balance pot, and a 3 wire 7.5” one for the 100k threshold pot. I secure these wires with a wire tie to the head phone & speaker wire near the connectors. I used one other wire tie to secure the pot wires together up near the pots.
Caution. Be sure that the pot closest to the end of the case doesn’t short out against the installed board components.
S.A.T changes. R32 220k resistor can be changed out. Raising the value slows the SAT. I have been installing a 375k running it through a toggle switch with the 220k. Giving a high & low setting of the SAT. One could use a potentiometer for variable results.
If your detector uses a ID meter, open the meter case, and replace resistor R28 (3.9 meg) with a 10 meg resistor. This aids in increasing the meter response depth.
Would these mods work on a Coinmaster Classic II?? Just wondering...
jdavis did u ever get an answer to ur question on the classic ll I would like to modify mine send me some email [email protected]
thanks
Hello
These mods are they compatible with the Classic 3 SLX ?
Thanks
I just bought a Classic ID and after reading about the mods. I do have one question.
VR1 and VR4 are both variable resistors with three poles each. . Mr. Bill says he uses two wire for the 50k and 3 wire for the 100k. Since I have yet to find a schematic can someone explain exactly how to wire in the pots.
thanks

Thanks Coin Chaser
That is just the info I needed. And with the three wire pot.. is it obvious how it wires to the board.? I am assuming the middle connection (not in line with the others) on the board where VR4 was removed connects to the middle post on the pot.
