Has anyone had any experience with A.H. ELECTRONICS, Quintron, or Phantom-they used a no motion mineral free discrimination.

I have not hunted with any of those machines, but hunted, back in those days (late 1970s) with a guy who had/used/tried them. If you're questioning that company's short-lived claim that they had a machine with TR disc, that could attain VLF-disc. depths WITHOUT motion fast-swinging, then here's your answer:
That was a marketing flop, and never held water in the real world of actual in-field detecting. I didn't get to use it personally, but just recall that it came under fire as being nearly deceptive advertising, because ........ no ....... it didn't match the depth of the then-new VLF disc (aka GEB disc). Hence TR disc went by the way-side in the evolution of detectors. It had the advantage of requiring no motion, but wained in mineralized ground, and lacked depth. The real death-knell for TR disc. came when the speed-required for VLF-disc got slowed down and improved. Because those early VLF motion discriminators were prone to masking, on account of the "tail" in the signals and the super fast whip required to get the extra "umph" of depth. But by the mid to late '80s, this problem was solved, and the era of TR disc. was over.

It was an off resonance detector and once you set it to disc out a target you could touch it to the loop anywhere and get no response.
The problem with the design was it was so inefficent it had little depth because it needed a little red wagon of car batteries to do anything.
The Barons when they first came out were advertised as 4 filter detectors, but were actually closer to 6 or 7 and they filtered out
too much information. Still they had TR-disc, and reverse discrimination was very deep.
Compass did make a motion free discriminator with the first surface blanking, in the Coin Magnum, and it worked as advertised.
But Teknetics came out with TID & depth reafing and they dropped it. Tek changed everything. I remember my Fisher distributor coming
by with the 1260 and I said, you need a pinpoint-they said its slow enough to pinpoint with. Walked over to a neighbor's yard where a bottlecap
had turned to mostly mineral, and brought a D-Tex. Swept the Fisher over it, got a coin signal-turned the disc up high, got a coin signal.
Took the D-Tex that was ground balanced, put it in VLF non disc, went over the target, it nulled out-then I dug it to show them.(Not long after they
did add a pinpoint-this was when you could open the housing and adjust the internal ground control.)
That was Dave Johnson's first great machine, and he is still building them.

great nostalgic look back. I remember all those machines, even if I didn't personally use them . Read about them in the then-current magazine ads (the various competing claims), and heard in our club meeting the pro's and con's of those trying them.
I still vividly remember when the teknetics first came out with their target ID, slightly before Whites copied them with their own version (the very first 6000d to try to incorporate a TID in about 1982 or '83). Anyhow, the teknetics dealer came to our club meeting to do a demonstration, and we were all floored! Jaws dropped around the room when the dealer waved a nickel. It sounded one way. Then he waved a pull-tab. It sounded another way. And then he waved a gold ring, it sounded YET ANOTHER WAY! Man you could look around the room and see dollar signs in all the guy's eyes
Several people at that night's club meeting ran out and bought the teknetics thinking they were going to get rich digging gold rings in all the parks, while effortlessly leaving tabs and foil behind. Wohoo! (you can't argue with a table demonstration like that, showing full-proof that a gold ring doesn't give the same reading as junk or bothersome nickels, now can you??).
Needless to say, it wasn't long before those early buyers soon discovered that there's still an AWEFUL lot of junk (can slaw, larger foil wads, beaver tails, etc...) that exactly mimic a variety of gold rings. Doh!
Ah those were the days

My first detector 1980, A.H. Electronic VLF/TR I was hooked on detecting with it. It didn't get very deep, you had to keep your thumb on the handle end which had a balance knob, keep turning it to keep the threshold. Good memories. After that machine (1980) Every detector I bought has been a Whites 5000D series 2 or 6000D series 2 and any 6000 after those. Those early 80's were a time of both front pants pockets (FULL) of coins! I keep and eye out for that A.H. detector on Ebay, just for the memories.
Well guys.I just bought an A.H. Backpacker II from Goodwill. Anyone in this forum know if this is a deep detector? Is it a T/R or a VLF-type? If it's a T/R, is there the issue with having to constantly re-ground balance? Can't be worse than the old Garrett 'Money Hunter' T/R non-disc. Someone give me your take on these questions I have please. Thanks.

Tallon,
None of the A H detectors are real depth demons - about 3 to 4 inches in moderate soil conditions. To the best of my knowledge, all AH detectors are Off Resonance detectors and they tend to drift -- however, your Backpacker 2 has auto tune which should help with the drifting. I have a rare Super Pro 2 Chest Mount and it's great in trashy areas.
You can download a manual for it (as well as the other models, including the Phantom & Quintron) at
