Vantage AD-14 prototype info

[nudels]

Hi I have a Vantage AD-14 prototype and I was wondering if anyone has any info on it. e.g. a manual, tech specs, what the two bottom knobs do, maybe an advertisement blurb from an old MD mag, etc.. the bottom left turns the unit on and you would think is volume control but it is not.

What I do know about the unit is that it has dual discriminating circuits (two top knobs), a toggle button switch on the grip, a pinpoint button on the grip and it is supposedly compatible with fisher coils from that era. Also, they had two models, the AD-11 and the AD-14, supposedly the bigger the # the deeper it went.

As you can see, the prototype doesn't have markings on the knobs . Also, it's quite a bit of circuitry in there, eh?

There is also a Vantage Electronics in Dallas that deals with detector equipment...may be related...you can google or yahoo them.

I can't remember anything about them except we had one dealer in the U.K. (North Wales Detectors) and they closed down years back and they were sold by KellyCo in the States at one time.
Thinking about it I think Monte posted something a year or two back about Advantage and Pillar. As Pillar was a Tesoro clone it might have been on the Tesoro forum.
