Bill how do you set up your C$?

This was the Coinstrike's #1 problem upon it's release. That the preset modes were WAY too "hot" for most of the country (work well in England) 
. High settings on the C$ promote RF interference, chatter, pops & clicks, etc. So, I have been preaching for years start with "525". That's 5 sensitivity & thresh back to -25. It' still powerful right there & that should have been the preset & it would have sold better. In fact, you can find coins with sensitivity on 1...it's that strong. All metal on the Coinstrike is wierd. Constant static so I rarely used it. Disc mode with disc on 99 works well. I have been playing with the disc to try to see right where nails break up. If I can find the breaking point on square nails like say disc on 55 (wild guess?) it could be even better in trash with the small coil.....
Also visit the "Coinstrike Homepage" for tips too..

Hey Bill, (sorry, I just now read this thread) I'm glad you mentioned the static with AM. I have found a few sites where it was tough to GB in all metal. It seemed like there was metal everywhere. I now see that it was the C$ at fault. I couldn't believe that some areas had that much iron so I assumed that the ground was highly mineralized. For that reason (when I was finally able to find a spot to GB) I set my sens to 4 and used autotrac hoping it would adjust to the mineralization. That's not a bad thing. Sens at 4 is still deep and I found a couple coins. The problem is..I also use AM to see how much iron is around and lower the sens if there is a lot. Now I think I may have been fooled by the C$ into thinking that there more iron than there actually was. Should I just use the 525 setting all the time? I live in New England so the ground should be similar to yours.
Thanks.
Thanks.

Hi Bruce,
I also had problems finding a good GB point on the C$ when hunting around old iron filled sites. Using the AutoTrac as you found out is a very good way to hunt those areas. What I normally did was to try and find a small area mostly clear of iron signals then turn on the tracking and sweep over that area 4-5 times then turn tracking off. I did direct comparisons on found targets near iron and the results using Autotrac to set the GB versus finding a nearby clean spot favored using the Autotrac method signal quality wise. Letting the C$ "see" some iron using autotrac to set the GB point seemed to be the key to success.

Definitely agree with using Autotrac to set the GB. Ground balancing seemed like it was always an issue with the machine telling me there was iron everywhere, when I knew there wasn't, but Autotrac solved that. I never could quite figure out a use for setting the disc to anything other then 99 
The C$ is a weird machine, just about the time your ready to wrap it around a tree, it finds something good, almost like in addition to all the advanced features Fisher built in, they included ESP

Yup, whether looking for a clean spot in all metal or when bobbing the coil in all metal I would sometimes get a huge positive response even in areas I new to be clean of metal. My feeling is that, at times the previous GB point was so far off from the current site that the detector is hitting on small hot rocks. Using the autotrac to set the GB and then going over the exact same areas that gave the responses previously those signals disappear. Although I like having manual GB available on a detector the Autotrac GB on the C$ does a great job.

The discrimination control, (0-99), is a iron discriminator control, and it will adjust the placement of the fourth, (lower), ID tone.
One can turn on ground tracking, and ground balance the unit with that on. One does not have to hold down the GB button with auto tracking on. Lower the coil to the ground & hold for a couple of seconds, lift coil up about 6" & listen for the GB tone. One thing to remember, when ground tracking is activated one may need to set the threshold to at least -5/-10 or lower. This would be in mineralized ground. You can try this, and see how it performs.
I think you will find that ground balancing in discriminate mode may work better.
A note about the Threshold control: Threshold is another was to control sensitivity.What you have with the CoinStrike is (2) two sensitivity controls. The "Sens" control & the "Thresh" control.
Sweep speed: Un-like the CZ series Fishers, the CoinStrike performs best with a brisk sweep speed. You don't have to swing it like a golf club, but don't move along like a snail either.
Have fun.

Hey Bill. I had one thing about the "525' setting. When I want to increase the sensitivity how should I adjust the threshold setting? I read that for every number you increase the sensitivity the threshold should be adjusted by five numbers. So 525 to a sensitivity of 6 would become "630" and 7 would become "735" etc... Does this seem about right? I mean, I'd like to know exactly "why" whis is, but I still don't, so I just do as they say on the forum with it. I think the difficulty with understanding the threshold control, by those new to it, is why the Coinstrike is frustrating. It's always nice to understand why your doing something when you do it. As far as groundbalancing goes, I read on the Coinstrike Homepage that you can actually keep the coil on the ground the whole time while setting the groundbalance holding the button in, and then releasing the button. This can be done if your going to be sweeping the coil across the ground (scrubbing the ground), as I believe I understood it explained. Thanks Bill. HH. Sincerely, Randy
"The Threshold control is best understood as setting the trigger poit between receiving a signal or not receiving a signal." This may be easier to understand if you read page #8 paragraph B of the owners manual. This will also help you answer your questions on the sensitivity, threshold relationship settings also.
On really needs to test settings like these before venturing into the field so you can see what's going to happen before you get into the field. Those 5/25 - 6/30 setting are just suggestions. They may not work well for you in your locations. Detectors need to be set up on a individual bases for the area your hunting. Fully learning what every control does is a must. Keep at it. Turn the controls, you can't hurt the detector. Do 1 control at a time, and when you learn what that control is doing, then move to the next one. Doing it this way, and you will never be fooled again.
Good luck
