coinstrike Question

[sasquache]

What does Proprietary operating freq mene ? on the coinstrike.Most detectors have a running freq of say 7khz or 14khz but Proprietary what is that.thanxs SAS

I can't tell you, its a secret LoL!

It means that the company deemed it a trade secret, chose not to publish it.

I take it that your into the manual now, that's good but the part about 'Threshold" will mess with your head. It's better explained in the Gold Strike manual, I suggest you download that manual. The rest of the C$ manual is okay. I can explain threshold to you if you need me to, but with the C$ its different then you may be used to. The C$ is a silent search detector by design.

Thank you Mark for your help but agane what is the running freq of the coinstrike ? or is it a mutli shift freq (I think i said that right) Does anyone know? Yes the Coinstrike manual is excellent but your right thay dont explain the threshold too good.I will check out the gold strike manual. Sas

7khz

Threshold is an adjustment or a gate trigger for the audio response, kind-a like setting the sensitivity on a motion detector, the closer to zero you get it the more sensitive it is.
But, it doesn't adjust the units detection circuit's sensitivity, only the audio circuit.

The sensitivity adjustment adjusts the detection circuit response to a target. (not the same as the threshold adjustment)

Think of the audio circuit as an alarm, when something from the detection circuit is feed to it it triggers the alarm. A threshold setting of zero and the audio alarm is really touchy to set off. The farther down the minus numbers (a higher minus number) and it gets less jumpy.

So more stability can be gained by dialing up a higher minus number, -15 less jumpy than "0" back it down to -40 and its even less jumpy. ect...

It most cases to gain stability with the Coinstrike users will work the Sensitivity and the threshold together, down a little on the threshold, try it, then drop the sensitivity a little.

To set the machine "HOT" both the sensitivity and the threshold needs to be adjusted,
Sensitivity = 10
Threshold = 0

But, a setting like this and the detector can really get jumpy and very unstable. (now your more likely to use the above settings with a small coil more often)

But a setting adjustment like,
sensitivity = 7 to 8
threshold = -15 to -20

and the detector is still pretty hot! but much more controllable.

6.25 kc

6.25 kc

Possible, but early on and talks with Bill Ladd, it was stated that the C$ ran at 7khz, I know its close to the ID Edge and the Edge runs at 6.25khz (that's listed in its manual)

But Fisher never released the frequency specification for the C$ keeping it "Proprietary" I've also heard that the C$ was a dual frequency machine, but I'm pretty certain it isn't.

The coils for the C$ and the Edge will interchange with a minor ground wire modification, but in my testing the Edge coils don't work as good on the C$ as the factory C$ coils do. The 10.5" Edge coil really helps the Edge on depth, but it on the C$ if it did anything at all it was less not more.

I would even try to argue about the operating frequency of the C$, I've heard a lot of different quotes about it, but we ran this out on here a couple of years ago and when the smoke cleared we all settled on 7khz ???

Sasquache... I believe I heard that the Coinstrike was operating at 7.6 kHz.

OPPS! a typo in my last post.

This line wasn't supposed to say "would"
I would even try to argue about the operating frequency of the C$,
It was suppose to read "Wouldn't" even try to argue!
sorry guys.

Boy its been a long time sense I visited that C$ home page, I'm surprised its still up.

Here is a post from the past, as you read it you will see just how confusing it was back when we all were trying to find the "Secret" frequency of the C$.

Since I'n not overly experienced with the Coin$trike I'm real happy that the C$ web pages is still online.

If it wasn't for FindMall's Fisher Classic Forum (CoinStrike forum) there would be no discussion on this detector either. Thanks Guvner!

Well I never found one of those solid bottom coil covers to fit the C$.
And I wasn't real thrilled with the pinpoint button modification either, I was concerned that it might mess up the membrane cover on the button.

If Fisher would have just put a pinpoint toggle switch on the C$ that would have been really nice.

Both the C$ and the ID EDGE run on 6.25Kc. Coils are interchangeable by cutting a ground on the C$.

I am almost afraid to ask,
But, where did you find the answer to this mystery question? "Proprietary" (company trade secret). We could never get a straight answer from the company about it.

The last time I ask this to a new member they told me they were at one time a technician for Fisher of Los Banos, (never seen much of them after that, maybe he was maybe he wasn't??)

They are literally hundreds of post on this very topic way back when the C$ was the new thing.

Thanks everyone for the awesome answers and schooling too my coinstrike question vary helpful. So there we have it a 6.25 khz should be a awesome coin/relic machine
