C$ Testing

Sven

Well-known member
Rain just won't go away.

Been reading the C$ reviews and noticed a bunch of people were claiming no depth. Not sure if it was all air test depth or actual in ground depth.
Have to say was not impressed with the air test nor on top of ground type air testing. My old Tesoro Amigo II picked up the coins gold at the same air test depth
as the C$ and sometimes beat it, especially with a faster recovery time........Trying all sorts of C$ settings really didn't help, neither did fresh batteries.
The worst part was the inability to pick up the Canadian half dimes more than 3", lot of them are found up here. I did ask jabbo to do an air test for me to see if
I could repeat it. Which I could. Still the C$ didn't see any good depth doing the on top of the ground testing. Read many folks are getting deep targets and wondering if my
C$ might be a dog. My PI not being set up for silver but configured for gold was getting better depth on the half dime and silver dime. So I sat back for a minute or two,
thinking, there's got to be more depth to be squeezed out of the C$. Remembering that some VLF, PI detectors air test poorly and do better in the ground.
It needs a matrix of some kind to go thru to get the depth. Then remembered Gunnar doing an air test-ground test using a stack of books as a matrix as it was winter time.
So I grabbed 3 old 3" thick books. Started retesting with the half dime etc. Amazingly found the half dime can now be picked up at about 6-7" with a quieter repeatable signal.
And able to pinpoint it in all metal mode. Silver dime was louder as well. Got the same results with all the other targets. Response and recovery time was also better.
At this point, it was clearly better than the one control, preset GB Amigo. Had me wondering there for a minute.....
Threshold was at -15, Sens 9, nothing notched, tracking off.

From this bit of experimentating, going to assume many folks sold their C$ on the premis of a bad, unimpressive air, above ground test.
 
Ground tracking can help if your really hunting DEEP. But it has to "Track" the ground to work correctly. What that means is lets say your testing the ground tracking over an 8" OLD test garden coin, You test over the coin with it off, then switch it on and go over the same target it might seem to do nothing, or maybe a tad worse?
The reason for this is because you went straight to over top of the coin and didn't give it any ground tracking time to analyze. if you do the same test and start out a couple of feet or more away and start swinging like you were hunting and sort of work your way to the target it will most likely improve the target response of the test target, this because the circuitry has a chance to process the ground and better council out the ground effects.

You must have found a read I never ran across, about everything I've read about the C$ the claims were it was a pretty deep machine. The Fisher units of that era were known for being deep.
But, deep to people mean different things. A Vaquero, may be deep, but after a point its pretty much all metal even though your still in disc mode. The C$ is MUCH deeper in that it still has a usable ID on coins down to around the 8" in average soil, that's nearing the realm of amazing. So, deep to a relic hunter who doesn't care about an ID reading is a lot different that a coin hunter trying to sift through the trash.

I learn something from all input. Here's what I think I know for sure. (1) All Metal mode covers a wider path than Disc mode and can detect deeper targets, is good to use when targets are far apart. (2) Disc Mode needs to be well centered over deeper targets to get any signal at all. (3) The coil is always in All Metal mode, even when were are searching in Disc Mode. But in Disc Mode the audio signal is chopped according to how high the discrimination is set or what we have Notched out.
 
I have my disc set so anything from ID'ing -30 and lower into the iron range will not report an audio response. I want to make sure I find those coins on edge.
A number of times, I noticed happening yesterday, my brain was registering possible two targets close by each other. Even tho it sounded like one bigger target, switching to pinpoint mode
confirmed two targets. It's something I picked up from using my PI for about 100 hours coin hunting.
