New circuit board has been installed as well as the rest of the parts, rand new waterproof search coil and headphone connectors.
Will operate on one or two 9 volt batteries. Two 9 volts give the detector extended run time.
Using a newer brown 8" donut search coil.
No more having to cut and or desolder wires when the detector needs service, switches and connector wires are now plugged into headers on the board.
Also took advantage of a little known audio volume control on the circuit board. Three solder pads for the speaker (headphone) wires. One pad is not used but there with a resistor going straight to ground. A pin header was soldered in that empty hole. The ground wire can now be plugged into this header. It will reduce volume output about 1/2. Which is perfectly fine, good for use with headphones with no volume control. For full volume output, the ground wire is plugged into the ground directly, good for use with headphones with volume control.
Powered the detector up this morning, works great, excellent air test depth. Was not able to use the waterproof (White's) headphones that came with the Silver Turtle. They would not function. Unfortunately, they cannot be taken apart without destroying them. Which I may do and make a new set from the inside parts. Or use just use a standard detector headphone set for now.
Next time, will put the snaps and mounting hardware back onto the case.

I dig it with a Nokta/Makro product.
