Help Still Needed on Vintage White's Coinmaster

As of this writing after 4 days & 114 members reading my previous post nobody has given me any response. As of today even White's Customer Service hasn't given me accurate info on my CM#3, Serial# F291 manufacture date P/68. I've attached a photo this time. I've never owned a Metal Detector before but I an a Ham Radio operator so I'm pretty savvy on electronic things. Here's where I'm at; This unit takes 2 - 9V batteries & they both check out perfectly on the meter. I don't really know what the Radio Tuner is for. When I turn the unit on I get a tone on the speaker & when I put the Null pointer to 10pm position & the Radio dial at 10 I get the loudest tone. I put a few quarters on the floor & when I sweep the coil across them the tone goes up as I pass over them however the dial on the meter doesn't move. Remember the meter does work when I test the batteries. So where do I go from here? Responses would be greatly appreciated.

Most BFO detectors operate the same way with the same controls. Very basic detectors.
You can also use Bounty hunter BFO manuals etc. http://www.whiteriverprep.com/vintage/bhvintage/bhI_II_III.html



Quest, Nokta, Makro Multi-Kruzer
Self built Mirage Pi's --- they work great in trashy areas!!

Well, I've had several bfo units and judging from your comments you don't want the loudest tone as you're too far into the metal zone and the needle will always peg and never move. At least back off the sound to where it just goes silent and work adjusting from there.

It doesn't peg full gauge. It never moves from the left. Only times the meter moves is when testing batteries.

Had one detector like that. Meter is somewhere disconnected from DETECTION circuitry.
