    Coil question for REG

    Reg. I had some free time,so I desided to see if I can get my CS4 pi to go deeper. with stock 10'' coil best it will do air test US nickel 7 to 8'' with sen (gain) set more +. I have a old 10'' CS6 coil it has the same inductions as the CS4 pi.They get the same dept at same setting. I...

    SL noise question for Reg

    Reg. The SL has a un-usal noise useing ground balance and conductivity switch. Useing the recharge-able battery at about 10.20 volts. The noise starts when SL is first turned on, ground balance on, conductivity switch at Low. I passed a gold ring across coil then I moved conductivity...

    Battery SL voltage question for Reg

    Reg. I have been reading battery voltage (TDI with 14.8V battery) on white TDI classroom. People are talking about useing 18V and 21.5 volts in there TDI. Will a 21V battery work in a SL with-our doing damage to SL. If so what is the highest voltage we can use. Frank.

    SL Microprocessor

    Reg. I cant or wont sell my SL until I can get more dept from the SL. If i remember right when you were working on the DOD coil the TDI that you were using the time delay was 8 lower or than 10. How did you reset the microprocessor to make time delay go lower.I suspect that you...
