Hello all,
I've had this detector for several years, it's in excellent shape (stock). I emailed Keith Willis couple of times a year or so ago inquiring about the depth mod and never got a response. Reading other posts it looks like he's not in the picture anymore. Does anyone have any details on the mod or how to tell if my detector may have already had the mod done ?
Thanks,
LJ

Look for resistor R112(Sensitivity Resistor). It is rated at 180 ohm. Replace it with a 100 ohm. This is what was stated on a website that is no longer around.
Hard to tell if yours already has it without opening it up. Best I can do to help.

You should achieve a 1 to 1 1/2 inch increase in depth.
