Sears TR-Discriminator Model 321.59642
Greetings treasure hunters,
I bought a Sears TR-Discriminator Model 321.59642 at a garage sale Friday and it's in pretty good shape for as old as it is. I found the manual for it online but it doesn't mention that it's necessary to 'sweep' the coil when searching. Years ago I had a more modern md and the instructions said to sweep it back and forth while searching. I'm sure there are many of you out there that are acquainted with this machine and can give me some tips on how to best use it. I realize that there are probably a lot better machines out there but I am operating on a fixed income and must make use of what is available to me. Thank you in advance for any information that you can give me regarding this old timer. Rj

It is necessary to keep the loop in motion if you are going to use this unit in the automatic mode. We used to set our units up so that they would just knock out foil. Any more and you'll start losing gold. In fact, by knocking out foil you are losing SMALL gold ...
Anyhow, our "2nd setup" was to just knock out pulltabs - no more. That will still get you all the coins except a nickel and larger gold rings and chains.
Here's the manual for your unit: http://media.whiteselectronics.com/m...ion Manual.pdf
Note that page 8 mentions keeping the detector coil in motion ....
Hope this is helpful ....

Thank you deoslyfox... I missed that part on page 8. Just in too big a hurry. Thanks for the tip on setting it up also. I figure it won't hurt me to dig some pulltabs. Rj

Welcome to the forum ,,,,That's quit the oldie you picked up ....Ineptocracy [in-ep-toc'-ra-cy] - a system of government where the least capable to lead are elected by the least capable of producing, and where the members of society least likely to sustain themselves or succeed, are rewarded with goods and services paid for by the confiscated wealth of a diminishing number of producers. There are three classes of people: those who see...those who see when shown...and those who do not see. - Leonardo da Vinci

TR vs GEB re.: motion/sweep
fox, I think you got Rj's question wrong. His machine is a TR discriminator, thus would not need motion (if I understood his question about the need to "sweep" correctly, to mean motion). On the old TR's, the disc would work ....... and the signal would continue, even if you stopped right on top of the target, with no "sweeping" or "motion" at all.
Contrast to the motion (aka: GEB, VLF-disc, SPD, etc...) generation of disc, starting in the later '70s and early '80s, where motion (or "sweepig") is required. By the mid 1980s, this began to be slowed down to real slow, but still "motion" none-the-less
Rj: your detector was made by Whites, and marketed by Sears. I'm going to guess it's probably circa mid to late 1970s. A real dinasour by today's standards. The TR disc. was great for its time (we could knock out foil, tabs, etc... for the first time! ) However, the depth was limited in disc. to perhaps 6", on coin-sized targets. A little more if you were in neutral ground minerals and really knew how to click & scrub. And worse if the ground was moderatly mineralized. In some states (the continental divide portions of states, and other areas of of some states) the TR disc. was limited to perhaps 2 or 3", or simply didn't work at all. When motion disc. came out in 1977/78-ish, it doubled the depth of disc. in some areas At first, it was crude, fast sweep, prone to masking, poor on low conductors, etc.... But by the mid 1980s was improved, slowed down, and now had TID, thus rendering TR a dinasour.

Tom: You and Giant are correct. I typed "discriminate" but was thinking "Automatic".
If you run the machine in non-Auto mode, you're absolutely correct. If you run the machine in Auto, you have to keep the coil in motion.
I corrected my post. Thanks !!If there's anything I hate worse than diggin' pulltabs, its missin' a gold ring.

I want to thank all of you for taking the time to reply. You've all been very helpful and also encouraging. I would love to be able to post some 'finds'. Thanks for the well wishes. Sounds like a nice group here. I'll be back when I find something. I'm practicing now. Best to all....Rj

Good luck !! Those old units have accounted for many a good find !!If there's anything I hate worse than diggin' pulltabs, its missin' a gold ring.
