How Old Is This Unit?

[Fisherfinder]

I saw this unit and was wondering just how old it was.

Is it "tube type"

If that is the Model 1 TR, it goes back to 1971. It might have the model number inside the battery door and then you can find and print the owners manual here: http://whiteselectronics.com/info/manuals.html

Thanks Larry, I was thinking it was even older.

It could very well be, it will depend on the model number.

The looks of its style looks like early 70s so I agree probably 1971 or close to it.
Good toy , unless it shows you what your digging. I remember them as having a needle and you didn't know what your digging. If you looking to cut down on digging junk good toy . I am planning on digging everything sometime soon. I am sure I miss a lot of things with my M6 by White's as some pennies have been reading twist tops and some smashed twist tops read penny. I notice distance from coil changes the reading on the display.. If right over it , it is usually correct. I found a quarter at 7 inches a clad reading like a clad dime or penny. I think for the beach dig it all. Around parks dig only good looking targets. around old homes not being lived in in a long time dig it all , same for woods and fields.

The reason you might have thought it was older than the early '70s, is the obvious "Buck Rogers" sci-fi type dials and appearance, right? Because by the early '70s, you would have thought that electronic gadgets (computers, etc...) didn't look like that. But since metal detectors were .... and still are ....such a niche hobby, financing and development are always a bit slower (or at least were back then) for the manufacturers. So there are some real goofy looking ones that, yes, can be as late as 1970-ish.

No, it's probably not tube type. Transistors came into being in the late 1950s. And by the mid 1960s (?) I would think that even the most low-funded low-tech factories would already have availed themselves of transistors, verses tubes.

If it is the Coinmaster 1TRDX then it operates from one 9 volt pack of AA and one 12 volt pack of AA batteries
If it is the Coinmaster 1 BFO then it is tube type and runs from qty one 1.5 volt fillament battery #353, one 9 volt #246 and one 67.5 volt #467 batteries.
Are 1971 vintage detectors.
