I have a chance to buy one of these through a private deal. It's advertised as "New In Box". Can anyone tell me approx. when these were made? What year? The person wants $60.00 for it..( price right?) .I've got a Garrett Infinium LS and the ACE 250 now...thought I'd have another back-up.

I have a 2900/D which I bought it in the 70's. Best I remember it cost around $80 at that time.
Found many silver coins with it before I lost interest in detecting for a long time.
It is old technology, but do not under estimate it's effectiveness at 5 to 6 inches- maybe more!

That can be a lot to pay for an older, simple detector. The 2900/D was introduced about 1985 at a suggested retail price of $179.95. It was a TR/Disc. model with an expanded range to adjust (compensate or balance) for the ground mineralization and provide an all metal operation, or you could reject unwanted trash. It operates at 6.59 kHz and could interchange coils with the other models of that era, which was pre-Blue max era. It was basically replaced in the spring of 1988 by the 2500/D, retailing for $149.95 and offering the same basic functions.


I've bought and sold a few of these in the $20-$35 range to have around for grandkids to use in the woodchip play areas. But I wouldn't spend much more than that, and even today I'd hesitate getting another because a Classic II would make a much better back-up. If you don't have a little 4

Monte, not trying to dispute your knowledge on those machines.
But, I do know for a fact that I bought my 2900D in late 1977 or early 1978. My hunting buddy was a coworker.

I don't consider it a "dispute", however, I was just referring to their catalogs.

My January 1976 catalog it has more models than you care to count! From the top of the line down they include: Coinmaster GEB 5/D, Coinmaster GEB 4/D, Coinmaster GEB 2, and Coinmaster GEB 1. Also shown are the TR Discriminators as follows: Alaskan TR 4B, GoldMaster 66 TR 4B, and Coinmaster IV TR 4B, the non-discriminating TR's: Coinmaster 2 TR2D and Coinmaster 1 TR2D. There was also the little Mini Master TR, and the five "budget" Beachcomber models. The Beachcomber 1, 2 and 3 were non-discriminating TR's, and the Beachcomber 4 and 5 featured TR Discrimination.

Beats me on the catalogs. I do know for sure I bought it in the late 1970's here in Austin when I was service manager for a TV repair shop. After that I went to work fo Texas Instruments for about a year and a half+. One of their suppliers then hired me and I went to California for a year. I quit them in mid 1983 and moved to Tennessee till early 1984 at which time I moved back to my home state of Texas. All that time I carried my 2900D with me.

Somewhat of a puzzle eh?
