FUNNY THAT THEY SCRATCH OFF ALL THE CHIP NUMBERS AND THERE IS A PROGRAMABLE CHIP THERE TOO !!! LOOKS LIKE AN OLD EEPROM ?? IF YOU DO NOT HAVE THE SOFTWARE FOR THE CHIP THE DETECTOR WILL NOT WORK RIGHT . SO SANDING OFF THE CHIP NUMBERS IS A WASTE OF TIME BECAUSE THE PART NUMBERS CAN BE FIGURED OUT IN A FEW HOURS WITH CAREFULL EXAMINATION OF THE CIRCUIT LAY-OUT AND OR OSCILLOSCOPE WAVEFORM ANALYSIS. BUT IF IT MAKES MINELAB HAPPY ITS OK WITH ME. AGAIN , NICE PHOTOS FROM NAKKY. .....................EUGENE

Small coin at 20 cm, coil is 15 cm diameter., frequency 5.6 kHz. But the most important is this: works good in difficult soil, can achieve small piece of metal. Maybe ultrasensitivity mode is an exageration, but discriminative capabilities is great at full. I dismantle and clean PCB for to copy. But the most difficult is extrange values of resistences. Post list of materials.

Dont know about you, but i am lunatic for sure! 100%

What i refered there is most uncommon way to label front panel command!
Never saw something like that before!

If you're 100% lunatic, I'm extreme lunatic as in front panel!

"OLD FORGOTTEN METAL DETECTOR'S"

HERE IS A LITTLE MORE INFORMATION ON COMPASS METAL DETECTOR'S . THEIR 1ST DETECTOR'S WERE THE
1. RELIC MAGNUM'S @ AROUND 4 KHZ
2. AROUND 1979 WERE COIN MAGNUM'S @ 5.73 KHZ
3. RELIC MAGNUM 7 @ 3.4 KHZ
4. THE MAGNUM 420,320,220, and 240 WERE @ 10.5 KHZ
5. THE DETECTOR'S WITH THE B MARKING OR THE "B" SERIES WERE AROUND 100 KHZ.
6. THE XP SERIES WERE AROUND 13.77 KHZ
AND BEFORE I GET TO MY FAVORITE COMPASS DETECTOR OF ALL TIME AND WHAT I AM REALLY LOOKING FOR !!! THE NAMES OF THE LAST OWNER'S WERE STEVE AND SUE GOSS. THE NAMES OF TECHS OR DEVELOPER'S THAT CAME UP WERE JOHN EARLE AND KEITH WILLS............ O.K. , NOW THE NUMBER #1 DETECTOR I AM LOOKING FOR IS THE COMPASS X-200 CHALLENGER !!!!!!!!!!!!! A DUAL FREQUENCY, 6 and 14 KHZ. ALL I COULD FIND WAS SOME OLD BLURRY BLACK AND WHITE PHOTOS.IT REMINDS ME OF THE OLD TECHNETICS COIN-COMPUTER. THE XL-200 IS BIG AND GREEN IN COLOR . SO ANYONE OUT THERE WITH ONE OF THESE "BEAUTIFULL BEAST'S" SEND PLENTY OF PHOTOS INSIDE AND OUT !!! THANK-YOU..........................EUGENE

"The X-200 Challenger is a manual ground balance, full-time target ID detector with three independent search modes. These include a true non-motion All-Metal, a motion discriminate, and a non-motion TR discriminate mode. In addition, an operating frequency of either 6 Khz or 14 Khz can be selected through a toggle switch on the control housing and a 1 or 3 filter motion discriminate circuit can be selected through touch pads on the meter face. It features a unique 3-piece shaft assembly which collapses to less than 24 inches in length allowing users to transport the detector in a carrying bag, backpack or suitcase without taking it apart.
The X-200’s operation is controlled by six knobs and two toggle switches on the control housing and five touch pads on the meter face. Starting in the upper right corner of the control housing and moving clockwise, the knobs are: POWER LEVEL (provides 5 different sensitivity settings for varying levels of ground mineralization); TRASH-OUT (used to set the desired level of discrimination); TONE (allows the user to vary the speaker tone to their personnel preference); GROUND NULL (used to cancel out the effects of mineralized ground); TRASH-OUT SENSITIVITY (turns the X-200 on, varies the detectors sensitivity in the discriminate mode, and adjusts the target ID meter’s response and sensitivity), and TUNER (adjusts the audio threshold heard thru the speaker or headphones).
Two of these knobs have features which deserve additional explanation. The TUNER knob has a position marked “Auto Tune” at the fully counter-clockwise position. In this position the X-200’s circuitry will automatically maintain a slight constant threshold by continually retuning the detector as ground conditions change. This feature, active only in the All-Metal mode, is particularly useful when searching saltwater beaches or for electronic prospecting.
When the TRASH OUT knob is turned fully counter-clockwise, the Auto-Notch circuitry is activated. This setting, designed primarily for coin-shooting, will automatically reject most trash items such as tinfoil, pull tabs, screw caps, and iron while still accepting nickels, pennies, clad, silver coins and some jewelry items. There are PRESET marks on each of the controls for hunters that want to get out and use the detector as quickly as possible. Even with the controls left at these settings, the X-200 will still provide above-average performance.
There are two toggle switches located on the right side of the control housing. The lower one labeled FREQ. is used to select the frequency at which the X-200 will operate. Unlike conventional detectors which operate at a set frequency, the X-200 can operate at either 6 or 14 Khz. 14 Khz is the preferred frequency providing more accurate target identification and greater sensitivity to small targets, particularly those made of gold. The 6 Khz setting is more sensitive to larger coins and silver objects and will also operate smoother in trashy areas.
Directly above the FREQ. toggle is another one labeled DISC MODE. This switch allows the operator to select either the motion discriminate or TR discriminate mode of operation. While the TR mode is affected by ground mineralization, there are a number a of applications such as hunting certain types of saltwater beaches, searching in confined spaces where the coil cannot be swept easily, and electronic prospecting where this mode will provide users with finds that may otherwise be missed.
The target ID meter, located at the end of the handgrip, provides the operator with a wealth of information. In addition to providing the probable ID of the detected target, signal strength and target depth is also indicated on easy-to-read scales. Below the meter are five touchpads which are used to select the operating mode (ALL-METAL or DISCRIMINATE), number of filters used in the motion discriminate mode (1 or 3), and turn the backlight on/off. The built-in backlight can be extremely useful for beach hunters who are forced to hunt after the beach empties at the end of the day.
As with selectable operating frequencies, the ability to select either I or 3-filter operation allows targets to be detected that other hunters may have passed over hundreds of times before. The 1-filter circuit is designed to allow for accurate target separation in high trash areas while the 3-filter circuit handles mineralized ground more effectively than the single filter can.
As with any manual ground balance detector, it is extremely important that the user takes the time and accurately balances the detector BEFORE beginning the search. By taking a few extra seconds, the detection depth and stability of operation will be greatly improved.
The X-200 is powered by 12 AA penlight batteries. Nicads are included and can be recharged without removing them from the detector. Battery strength is indicated on the meter each time it is turned on. Fully charged nicads will provide approximately 10 to 12 hours of use and alkalines almost double that amount. The use of headphones will further extend battery life and a standard 1/4 inch jack is located in the rear corner of the control housing for this use. "

"OLD FORGOTTEN METAL DETECTOR'S"

WHILE WE ARE WAITING, AS GEOTECH MEMBER'S ARE SEARCHING LIKE MAD FOR THEIR OLD COMPASS X-200 CHALLENGER !!!!! HERE ARE 2 MORE DISCONTINUED MODEL'S , THIS TIME FROM RADIO SHACK . THE BLUE-ISH MODEL I SHOW HERE IS DISCOVERY 3000 ,I BELIEVE WAS TOP OF THE LINE AND I THINK THE R.S. # NUMBER WAS 63-3015. AND THE RED-ISH COLOR MODEL WAS THE DISCOVERY 2000. I DO NOT HAVE THAT R.S. #NUMBER. BUT THESE 2 ARE DISCONTINUED AND YOUR INSIDE-OUTSIDE PHOTOS AND SCHEMATICS ARE VERY WELCOME !!!!!!!! HAVE A GREAT DAY EVERYONE..............EUGENE

"OLD FORGOTTEN METAL DETECTOR'S"

THE DETECTOR I AM POSTING NOW IS A "TRUE CLASSIC" . IT WAS TESTED AND RATED AS A "TOP OF THE LINE" DETECTOR. 12.5 KHZ AND WAS POSTED ORIGINALLY ON DECEMBER 2. 2005 BY KT315. IT WAS A HOT TOPIC THAT JUST FADED AWAY. IF IT WAS BUILT AGAIN I BELIEVE THE CIRCUIT BOARD WOULD BE EASY BUT NOT THE SEARCH COIL. THE FIELD TEST DID STATE THAT THERE WERE SOME PROBLEMS WITH THE SEARCH COIL CAUSING FALSE SIGNALS . BUT IT DETECTED TARGETS DEEP !!!! .......................EUGENE

"OLD FORGOTTEN METAL DETECTOR'S"

HERE IS ONE THAT REALLY "DISAPPEARED" !!!!! I WONDER WHY ????? DID IT WORK TOO GOOD FOR IT'S PRICE ???????!!!!!!!!!!! THIS MODEL IS NOT BEING SOLD OR MANUFACTURED ANYMORE. REMEMBER THE GTI-2000 ?? SO, AGAIN YOUR PHOTO'S ARE WELCOME , INSIDE AND OUT......TAKE CARE ALL............EUGENE51

[amtech2005]

"OLD FORGOTTEN METAL DETECTOR'S"

HERE ARE A FEW MORE PHOTO'S OF DISCONTINUED MODEL'S . AND I AM STILL LOOKING FOR A CLEAN PHOTO OF MICRONTA DISCOVERY 3 !!!! ESPECIALLY THE CIRCUIT BOARD, WHICH WAS REALLY A BIG BUD PRO SED !!!! OK SO HERE ARE 3 PHOTO'S WHICH HAVE A SIMILAR CASE, 2 ARE "BOUNTY HUNTER MODEL'S" AND ONE IS MADE FOR RADIO SHACK. TOP LEFT IS BIG BUD PRO. TOP RIGHT IS MICRONTA DISCOVERY 2 AND BOTTOM RIGHT IS TRACKER I.D./505...............EUGENE

"Old Forgotten Metal Detector's"

Here is one we should not forget !! It was a very popular low-priced detector from
Radio-Shack. I know this Detector can be modified. Even the search-coil can be up-graded. It sells for an average price now of $25.00 Dollars.......... Here it is...........................Eugene
