I use an older 1994 Minelab Sterling as I can no longer afford a top of the line unit. It gets the job done.
And has surprisingly good depth.
I also picked up a 1980 detector cheap that needs some work. Like the one pictured that I once owned.
If I can getting it functioning correctly, in VLF mode will be more than happy to use it. These units went
deep, depending on soil conditions.
I am seeing vintage units selling for more $$ than last year, especially top of the line units of yesteryear.
Some selling close to orig. retail price......... I don't think the bulk of these buyers are collectors
But these vintage units are still 50-75% cheaper than currently priced top of the line units. Even those
earlier TR units are escalating in price. I pity the person who tries to use one of these and can't keep the
coil at a constant height & level to the ground during each sweep. Many of those buyers of vintage units
probably would have been better off spending the money on a current lower priced model that would match
or exceed the vintage units performance. And have a warranty to boot.
Current Tesoros and the Garrett Ace seem to be doing well for the money spent. Especially if most of your finds
will be in the first 6" of the ground.
