C-Scope Electronics is the leading manufacturer of metal-detecting equipment in England and they are presently exporting their latest line of detectors to the United States. The first time I saw their two new detectors was at the Treasure World Hunt held in August 1990. David Colwell, owner of C-Scope, attended the hunt and had both the detectors, as well as some of the many finds from England, on display. The display attracted quite a bit of attention, and I was interested in trying one o the units out under various conditions.

FEATURES

The CS2MX is the top of the new line of C-Scope detectors and is an automatic ground-canceling, silent search, motion discriminator with two independent discriminate circuits and a non-motion ALL METAL pinpoint mode.

The detector is mounted on a modified S-shape handle and, at only three pounds (with batteries and searchcoil), is one of the lightest detectors on the market today. The control box is secured with two screws and is easily removed from the rod for hip-mounting or when searching in shallow water.

The CS2MX comes equipped with an eight-inch concentric search coil which is completely waterproof up to the connector at the control housing. C-Scope has incorporated a rather unique wing nut to fasten the loop to the lower rod that allows the user to tighten it with only two fingers.

There are three knobs and two push buttons located on the face of the control housing which control the operation of the CS2MX. The SENSITIVITY control, located in the lower left comer, turns the unit on and is used to adjust the strength of the signal being sent out. The two knobs located in the upper left and right comers are used to set the level of discrimination desired in either of the two discriminate modes.

The push button located in the lower left of the face labeled PINPOINT is used to select the all-metal, non-motion pinpoint mode. The push button located next to the PINPOINT button labeled DISC 2 is used to switch to the second discriminate circuit to aid in identifying a target before recovery.

There is a standard 1/4-inch headphone jack located in the lower right comer which should be utilized to enhance battery life and hear the weaker signals.

When the detector is turned on, the batteries are checked and a tone indicating their relative strength is produced. New batteries will produce a tone for five seconds, and when the tone lasts for one second or less, the batteries should be replaced.

The CS2MX is powered by eight AA penlight batteries which are located in a compartment in the bottom of the control housing. The compartment is sealed from the electronics of the detector which prevents damage to the circuit board if the batteries leak.

The set of batteries that came with the detector provided me with almost 30 hours of use, and the detector had been used as a demonstrator before I received it. Alkaline batteries will provide approximately 10 hours more, and rechargeable ni-cad batteries can be used with no loss of performance.

INITIAL IMPRESSIONS

After reading over the instruction manual that accompanies the CS2MX and familiarizing myself with the controls, I performed an air test to see how the detector responded to various targets. Selecting several items from the display case at the C-Scope table-including coins, jewelry, and small artifacts - I began to pass them in front of the loop.

The CS2MX did a good job of rejecting trash targets while still accepting targets that fell above the discriminate settings and was able to detect the test objects at fairly impressive distances from the loop.

David Colwell demonstrated the ability of the CS2MX to detect a good target adjacent to a trash target by holding a coin and a nail side by side and passing them by the loop. The detector produced a solid, repeatable signal yet when the coin was removed, the CS2MX did not even chatter when the iron nail was checked.

The next features tried out were the two discriminate modes. The dual independent discriminate circuits on the CS2MX are extremely useful in providing the user with information on the type of target detected, thereby reducing the amount of unnecessary digging. For coin-hunting applications, the DISCRIMINATE 1 control should be set to the preset mark which will reject iron and tinfoil.

When a pull tab is located, increase the DISCRIMINATE 2 control to the point that the pull tab produces a broken or scratchy signal. When a target is detected, it should be rechecked in the DISCRIMINATE 2 mode.

If the signal did not repeat, it would probably be a nickel or small piece of gold jewelry. If the signal was sharp, it would be a coin (other than a nickel), silver object, or possibly a large screw cap. A broken signal would be passed up as it would be a pull tab. With a little practice on known targets, one can ignore most trash targets found in a particular area by utilizing the two discriminate circuits.

We took the detector outside the ski lodge where the displays were set up to see how it worked in the ground. David set the SENSITIVITY and DISCRIMINATE 1 controls to PRESET, the DISCRIMINATE 2 control to 7 1/2, and started to sweep the area where the Tune-up Hunt had been held the night before. The first few signals produced a clear signal in Discriminate 1 but produced broken signals when checked in Discriminate 2 and turned out to be pull tabs.

Near the ski lift we received a signal that was clear, but was completely rejected in the #2 DISC mode. Cutting a deep plug produced a blackened 1964 nickel from 4 inches that had obviously been there for some time. The only target that produced solid signals in both discriminate modes turned out to be a 1944 Mercury dime at 3 inches left over from the hunt.

FIELD TEST

The first chance I had to actually test the CS2MX was in the afternoon hunt. Since the field we were to search had very little trash in it, I set the DISCRIMINATE I control to just below the PRESET mark. Since I was planning on digging all targets that registered above the #1 setting, I disabled the DISCRIMINATE 2 circuit by turning it fully counterclockwise.

I set the SENSITIVITY control to the 3:00 o'clock position which provided me with the greatest sensitivity while eliminating any chatter which might be caused by changing ground conditions.

As we were waiting for the hunt to start, the CS2MX received a fair amount of interest from some of the other participants, and many people expressed an interest in trying the detector out after the hunt was over. With a wave from the hunt officials, the hunt started and hunters quickly covered the field.

After only a few sweeps, I received a signal that produced a solid response. Pressing the PINPOINT push button, I quickly centered the target and cut a plug to recover it. At slightly over 5 inches I recovered a 1941 Standing Liberty half; not bad for the first target found with a new detector (even if it was planted).

The next few signals produced silver dimes and several wheat cents at depths of up to five inches. Near the edge of the field in the high grass, I received a soft signal that was repeatable. Switching to the PINPOINT mode, the target appeared to be fairly small and deep. I cut and removed a deep plug and rechecked the hole. The CS2MX indicated that the target was now in the plug, so I carefully started to break it apart. Nearly three inches from the surface of the plug, I found a sterling silver hat pin with a rather ornate end.

The hunt officials stated later that it had not been buried and must have been lost years earlier. While my total finds in the one hunt only amounted to a dozen silver coins, one prize token, some wheat pennies, and the stick pin, the CS2MX had performed well and, due to the 12 KHZ operating frequency, had not been affected by any other detector on the field. Having attended a number of hunts where other detectors from the same manufacturer have nearly forced me to leave the field, being able to hunt with no interference was a welcome change.

On my way home, I stopped off to do some treasure hunting in Oswego, New York which is located on Lake Erie. My first stop was the state university which was founded in the late 1800s. I set the DISCRIMINATE I control to the preset mark and the DISCRIMINATE 2 control to just above 7.

With the controls set this way, a pull tab would produce a broken signal when checked in the #2 position while a nickel or small ring would be silent and a penny or clad coin would produce a solid signal enabling me to determine what a target was before retrieving it. Hoping that the grounds had not been hunted out, I started searching near one of the older dormitory buildings.

After several minutes and not receiving any signals I began to wonder if someone else had beaten me to the coins I had hoped were there. Finally, near the building, I received a soft signal that came in clear in the #2 Discriminate mode as well. Carefully pinpointing the target, I recovered a 1936 wheat penny from 5 1/2 inches deep. Hoping that there might be some silver in the area, I slowed down and overlapped each sweep.

After 20 minutes of careful searching, I had added two wheat cents from the 1950s and a dozen clad coins to my pouch when a campus maintenance vehicle pulled up. As the maintenance worker headed in my direction, I wondered if I was about to be run off. After introducing myself and explaining what I was doing, he said that I was probably not going to find much since the area I was searching had been filled and leveled a few years earlier. He recommended that I try across the street near the activity center as that building dated back before the college was founded.

I thanked him and headed across the street. Leaving the controls where I had set them, I began to scan the grassy area in front of the building. The first 2 signals both produced wheat cents from the 1940s at 4-5 inches.

The next signal was a sharp signal that appeared to be quite small when checking it in the pinpoint mode. As I removed the plug, I caught the glimpse of silver in the bottom of the hole and carefully removed it. While it was not a silver coin, it was a small silver locket that opened, with the initials HAW engraved on the front. Based on the style of writing, it dated to the turn of the century.

After an hour, darkness forced me to leave but I had recovered 23 coins and the locket. Unfortunately I had to leave the next morning; however, I hope to get back to Oswego for more hunting.

Arriving back home, my wife, Rosanne, and I took the CS2MX to a local beach that is used quite heavily during the summer. I set the DISCRIMINATE I control to 3 which would eliminate the small bits of iron such as bobby pins and barrettes, but would not reject any small pieces of jewelry which I hoped might be present. In order to avoid missing any good targets, the DISCRIMINATE 2 mode should not be used as it is best to dig all targets, except iron and foil, when beach hunting.

After a few minutes of searching the beach and finding little other than pull tabs and an isolated penny or two, I headed into the water. Over the years, I have found that one of the most productive and overlooked areas in the water is from the shore to knee deep. Mothers play with their children and often a piece of jewelry is lost -just waiting for a treasure hunter to find it.

As I walked across the beach, I recovered a number of coins and, more importantly, very little trash as compared to the dry sand. After covering nearly half the beach, I received a soft signal that was repeatable as I checked it from different directions. As the sand began to flow out of the scoop, I saw the glint of gold in the bottom and removed a very delicate 14KT ring with a small blue stone. Continued searching produced almost $8 in change; however, no more jewelry was found.

I tried the CS2MX out in a number of other areas in the Atlanta area and was able to add a fair amount of clad coinage as well as some older coins and artifacts to my collection. The detector worked well even in the highly mineralized ground in this area; however, the sensitivity had to be decreased in order to eliminate any chattering or falsing.

SUMMARY

The CS2MX is a versatile detector that performed well in coin hunting, competition hunting, and shallow-water hunting. It is extremely simple to operate, and the two independent discriminate circuits allow the user to fairly accurately determine what the target is before deciding to recover it.

The audio level from the internal speaker is fairly low and, at times, it is difficult to hear some of the deeper signals in areas of high background noise; therefore, the use of headphones is required in most areas. Most headphones sold in the United States do not function correctly with this detector, so a set of high-quality headphones is included with the detector and will not only enable the user to detect even the deepest signals with ease, but result in longer battery life as well.

The CS2MX retails for $489.95 and comes with headphones and a two-year warranty.
