CS-6 Test Drive Observations

A

Anonymous

Guest
I hit the Long Beach Island (LBI), NJ Beaches (Surf City) this week to test drive my new C-Scope CS-6PI metal detector. The LBI beaches typically use wood-lath and ferrous metal wire sand fences to attempt to retain the sand. Remnants of the metal wire in these sand fences litter the beaches. Yes, I know, that PI machines are no good on thse type of beaches. I just had to use the CS6 anyway. I have some observations and some questions for those of you more experienced with PI machines.
1. The volume of all targers deep and shallow is pretty much the same. I am familiar with the ML Sovereign which has a pretty wide dynamic range and can tell deep from shallow targets pretty well. The CS-6 sounds about the same on most targets between 1 and 7 " except nickles which, for some reason, sound louder.
2. The depth was not as deep as my ML sovereign. The deepest target was about 7" using the CS-6 while I normally get 15" using the WOT. I am going to use an extenal "Depthmaster" amplifier/limiter to see if that helps somewhat.
3. I realize that the CS-6 is hotter on gold than the Sovereign. I got a thin earring and a small religous metal on my first day out. Should I be getting more depth on quarters than 7"?
4. I used the double beep technique to identify the ferrous metal littering the beach from the coins. On the first day out, I acquired quite a collection of ferrous fence remnants...7 ferrous to one coin ratio. on my second day out it dopped to about 3 to 1 and on my third day out is was about even. Ferrous metal laying horizontal are easy to identify with the classic double beep. Those ferrous pieces that are diagonal or more vertical require digging. Is there some other technique that I should be using?
If those of you familiar with PI machines or in particular the CS-6PI could respond, it would certainly help me understand the potential of this new PI machine.
Thanks for a very informative forum. It was this forum that causes me to try a PI machine.

Hi bbsailor,
I did receive your email, and I will try to answer it, and your post.
Targets between 1" and 7" are shallow targets for the CS6Pi. When hitting on deeper targets the audio would be at a lower level. Nickels sound louder than quarters because the sensitivity toward the nickels is greater. Nickels are a closer representative of gold targets than clad quarters. It is not uncommon having your PI to hit on nickels deeper, stronger than clad quarters. I wouldn
 
HI bbsailor,
I have been using PI detectors for the past twenty years, and if you dont want to end up with a crippled back, dont use them where you have a lot of iron.
I would have thought your "Sovereign" would have been your best bet with all that ferrous wire about? I have not had any expierience with the "Sovereign" but I have been told it has good discrimination over iron. Do you find the bits of wire right down to the waters edge and out to waist depth?

I make mention about re-tuning the CS6 to be more responsive to different metals, like clad coins. Very few PI detector are able to do this. All that I am aware of are Eric Foster designed units. This is because when adjusting the "frequency", "pulse delay", or what other the name of the control is called, it changes a lot of circuit adjustments.
It is not just a "pulse" delay control. It changes things like "pulse width", pulse rate", "pulse frequency", "pulse delay", ect. This is why the user can re-tune the detector toward certain metal targets. It is also why one can use this same control to determine if it

=================================================
You are making me doubt myself here with this statement. Isn't pulse rate and pulse frequency the same thing? Are you sure that it varies the pulse width? If so, is that important in "retuning" the detector towards the desired targets?
In the detector I'm designing, I took great pains to be able to adjust the pulse delay without affecting the overall frequency. Maybe I just did all that work for nothing <IMG SRC="/forums/images/smile.gif" BORDER=0 ALT=":)">

Mr. Bill,
Thanks for the quick response.
I was using headphones. I use in-ear, ear pods with a 21db sound silencer isolation muffs on top to keep out the surf noise.
Is there a best impedance headphone for the CS-6?
Even close targets are not what I call loud.
Is this normnal or is there an internal adjustment to up the volume a little?
I also plan to hook up my "Depthmaster" which amplifies and limits. This is a killer combination on my Sovereign in the all-matal mode and a WOT coil.
My statement about the apparent depth compared to the Sovereign was just to make the point about the dynamics of the CS-6 PI seemingly being less. Is this just a CS-6PI characteristic? or
Is this due to the log-like nature of the amplifier gain circuit?
I knew that the Sovereign would be better on the wire littered beach. I just wanted to "kick the tires" on my new PI machine at a conveniently close beach and get familiar with it even under less-than-ideal circumstances. Even in these conditions, I came away with more than a 100 coins, two pieces of jewelry, and a nice collection of fence wire in a about 6 hours. I was using the frequency control in the most counterclockwise position for jewelry.
I was working the area between the high and low water mark at low tide. There is a 3-4ft cut at the beachs at Surf City NJ and I was working the area where I got the most keepers. Most coins were 20+ years old; no pre-1965 silver. I guess I need to wait for a "big one" to hit for the real old stuff to show up!
I have also acquired quite nice collection of lead fishing sinkers. The CS-6PI seems pretty good on these also.
Pinpointing on the CS6 is pretty good and that makes recovery rather quick.
Here is a little tip that I have developed. make a bucket sized basket 12" in diameter and about 12" tall using a plastic hoop on top and 1/2" wire mesh. Attach a rope across the basket as a handle and tie a 6 ft rope to the rope handle to drag it behind you. Use a long, wood-handle shovel and just drop your findings in the basket. When coins are a plenty this make quick recovery.
You also need to tie a lanyard between the shaft of the CS-6, under the upper part of the control box (for best balance), and your waist belt to free your hands to do a quick dig.
The reason I got the CS-6 was to increase my gold finds, not my coin collection. I am in no way critical of the CS-6; I just want to ask the right questions to accelerate my learning and hasten by gold findings. I have used my Sovereign for several hundered hours and have found only a small amount of jewelry and lots of deep coins. Granted, it depends as much on oprator skill as it does on where it is chosen to be operated.
Great Forum,
bbsailor
BTW, when sailing season is over on Barnegat Bay NJ, I pick up my metal detector and hit the beaches until spring.
 
Bob,
You are right about the Sovereign being better on iron littered beaches. I have solved the back problem by using a long-wood handle shovel and a home-made wire-mesh basket. This makes for quick recovery. Even questionable targets are easier dug than pondered.
Between the 3-4" cut and the low water line is about 25 yards. As I work closet to the water the frequency of detection for all targets falls off. At the water line the sand is very mushy and my feet start to sink. I guess that super saturated sand allows most targets to sink deeper beyond the range of the detector. I need to wait for the soft sand to be removed by a "big-one" or a sustained nor'easter. Once hard pack shows itelf the old coins and hopefully jewelry will be found.
Thanks

Hi BB,
Theres is No internal adjustment to up the volume
but if you want to invalidate your guarantee :)
by carefully unscrewing the battery/speaker box, theres a 270R resistor in series with the audio wire to the earphone socket, if you lower its value or short it out the volume will be much stronger to your yerholes
Rob..
 
Bob,
It would be good to try your Depthmaster on the CS-6. Because the real deep targets only give you a very small short sound. It takes a while to learn this sound. This has been my experience with the CS-7. The deepest that I have dug a gold ring was a measured 15 inches. When you start getting nickels over 12 inches. You will have learned what this sound is.

Thanks for the response Bill! Once I recover from Christmas expenses I still hope to buy a Deepstar.
Happy Holidays,
Charles
