Is there someone out there that uses the C$ for relics. I've read about them in this forum and recently had the chance to buy one. It seems to be a remarkable machine. I still do not understand alot about it (how threshold mixes with sensitivity). I'll just use the productive settings that others have shared and change as mineralized ground demands. I was just out today playing around with it and able to discriminated the square nails while piicking up a melted minnie ballsized chunk of lead, a eagle button, and a nickle. However, I could not get it to pick up regular minnie. It showed a +21, and fairly consistant, on the screen, but no sound. The lead weight was close to the same as the minnie ball but a little different in form. Can some one explain? Thanks.....

Settings for the C$ for minnies

The Display is ALL Metal! the Audio is discrimination.
A plus 21 on the ID screen would put it at the Zinc penny range, the reason you didn't get any audio at 21 is most likely the Zinc penny range has been NOTCHED out (notched to reject that range) See the manual for setting the notches.
Also the label for the notch markings are sometimes a little off line with the marking on the screen.
Threshold vs Sensitivity
It a little easier to understand it if you think of it like this,
Sensitivity is adjusting the detection circuit's sensitivity, while the threshold is more about the trigger for the audio circuit, lower the threshold number (minus numbers) the more response the audio circuit needs to signal a audio reports.

I knew you could tell me Mark and I appreciate you answering the question. I can't remember what number the chunk of lead was but it had to be higher than the zinc range. The lead chunk was giving a high tone. The button and nickle was a low tone. And, I did have the zinc notched out. I'll play some more tomorrow. What numbers would you use for Relic hunting in moderate mineralized soil. The C$ seems almost new. I just have the 7 inch coil with the Sunray probe that allows me to use Edge coils. Can the Excel coils also be used also.....Thanks......

I've never heard anybody say or confirm that the Excel coils are compatible with the C$ so I'm going to say probably not!
You really only need to add one tiny jumper to the Edge's coil connector to use them directly on the C$ its an easy modification to do.
Well, I would think you would want to run it as hot as you can and still maintain stability, HOT setting are with the sensitivity MAX and the threshold at (0) to any positive number. But keep in mind that above zero the C$ is no longer a silent search detector.
Next! is the discrimination settings, I would keep the disc control set near 99 that above small iron, set all the notches to except.
Lead is a higher conductor and I would think that any bullet above a 22cal should come in at lest the zinc range or above.
You will probably not be able to run the max settings with the standard coil, but you probably would with the smaller coil.
Don't over think the C$ its not as complicated as the manual makes it out to be, you may want to download the manual for the Gold Strike for a little better read about the threshold control.
Also, the preset coin program uses to hot of settings for most new users, so I don't recommend using it to start of with.
The C$ also holds or stores the last settings used except for ground balance.

Yes, there is both Los Banos (old Fisher models) and later First Texas models. So, the C$ was one of the model lines that was in the transition group.
The C$ was first then came the Edge then I believe the Excel came alone.
I've had both, the Los Banos and a First Texas C$ I believe the later one Ground balanced better, in that you could tell for sure when you got it right, the Los Banos model's ground balance almost didn't seem to do anything, I mean it would go through the process and beep but I never got any hint that after or before it was ground balanced that anything changed. I could turn it on and hunt the same ground and as deep without ground balancing as I could with ground balancing it?
Of the two I had I would have to say that I liked the first one I had a little better than the second one.
After First Texas took full control of Fisher a lot of models were cut from production and all the lifetime warranties were cut off. The claims were the old Fisher company was in deep financial trouble and to save anything and turn a profit First Texas streamed line the product line (cut out production) of certain models and early on the C$, Gold Strike, Edge, and Excel was probably the first to be discontinued.
The C$ wasn't in production long enough for it to have gained much interest in the aftermarket world, Sun-Ray did make a few things for it, some also feel that the design of the C$ was a little ahead of its time and that really hurt its market appeal.
If you keep an eye out in the forums and Fleabay one of the small coils will turn up, I'd say the best price on one would be on a forum.
