i still have a working silver sabre with the 7"concentric coil.
Introduced in 10/'83 a good one still finds a lot of coins and such, and uses the good 7" Concentric coil. I sold a friend and hunting buddy a brand new one in May of '86 to get started in the hobby, and we went to my favorite ghost town in October of '86 when she nabbed a gorgeous 1880 CC $5 gold coin. Her Silver Sabre still works today, beaten and abused, but it lacks the performance of some newer models, which she uses now.

Might not need one. If interested, why? There are added features to an up-line model that provide some versatility and I would suggest shopping for a newer or current Tesoro to have more performance, search coil interchangeability, and more functional controls.

as they both operate in the 12klz and the compadre has a reputation for finding small gold chains and jewellery,would not the sabre do as well,as they both operate in the same frequency,emubob
The operating frequency doesn't really mean all that much with many makes and models, especially most of the "general purpose" Tesoro's. Tesoro-made models have operated from 9.6 kHz to 15 kHz and all use the same search coils and there's not really an edge for gold jewelry due to operating frequency.
Where the Compadre has a bit of advantage at responding to small gold chains and other lower-conductive jewelry, is in the Discrimination range of acceptance. The original Silver Sabre and other early Tesoro models had a lot of Discrimination at the minimum setting. Many hobbyists found their Tesoro's lacking in performance on small gold rings and thin chains. In 9/'91 Tesoro brought out the Silver Sabre II which was the preset-GB model that had the then-new ED-120 Discriminate circuitry range. That was Tesoro's move to provide better performance on the low-end conductivity targets.
The Compadre, however, is one of only a few Tesoro models that offered an ED-180 range of acceptance, and at the absolute minimum Disc. setting the Compadre will have virtually no rejection. It's in an All Metal accept Discrimination setting, thus superior to the old Silver Sabre. You can toggle your Silver Sabre into the All Metal setting, which is still a motion Disc. mode and comes very close to accepting all metals, both ferrous and non-ferrous. In a trashy site with a lot of iron most hobbyists don't care to hear it all.
The better Discriminating Tesoro models, to respond well to low, mid and high conductive targets but best deal with iron rejection, are the earlier models with the ED-120 range of Discrimination acceptance. That was introduced in the Tesoro circuitry design with the original Bandido in 3/'90 and would include models such as the Bandido, Bandido II and Bandido µMAX, Cutlass II, Golden Sabre II, Pantera, Silver Sabre II and Toltec II.
There are newer models that also have the ED-120 Discriminate range, but they also had a newer "low-noise/high-gain" circuitry and while they could adjust lower to hit on thin gold, etc., they also have a little more noise and problem in a dense iron littered site compared with the former models I mentioned. Still, all the newer ED-120 models will hit on lower-conductive gold better than the limited Disc. range units like you have.
