1 1 FEA TURES The GT Ax 550 is designed with Garrett's exclusive Graphic T arget ID technology , which indicates the probable identity of a target along a horizontal scale that reads from low conductive metals (e.g iron) on the left to high conductive metals (e.
is detected, the T arget ID cursor will appear below the word or symbol that most likely indicates the type of target found, based on its conductivity .
13 5. BA TT (Battery) - Battery condition is reported continuously by the horizontal row of squares on the lower right of the GT A display . Four are visible when fully charged batteries are being used. When only one square remains, battery life is two hours or less.
weighs less than 2 pounds. Y et, all of the controls are still easily accessible and your GT Ax 550 display is visible on the control stem of the detector . The removable hip mount pack and built in coiled cable permit easy reassembly for carrying and storage.
15 TOUCHP ADS / CONTROLS 1 . POWER - Press and release the POWER touchpad to turn the detector on and of f. Note: After turning the detector off, wait 3 to 5 seconds before turning on again. The POWER touchpad can also be used to reset all settings to factory preset by pressing and holding for 5 to 10 seconds, or until the detectors beeps.
2. PINPOINT (Coin Depth) - Activates pinpointing function and indicates depth of coin-sized targets on the Lower Scale of the Graphic Display . 3. LAST MODE - Returns the detector to the operating mode previously used. This touchpad can be particularly helpful while scanning because it effectively converts your GT Ax 550 into a dual mode detector.
17 increase depth and sensitivity; press (-) to decrease. A single touch and release adjusts the level in a small increment. A continuous pressing results in a continuous adjustment. When you have made your adjustment, press Depth again to reenter your previous operating mode.
interference and irregular ground mineralization may sometimes require reduced sensitivity which usually results in less detection depth. Do not worry about losing "deep" targets when you reduce this setting. Y ou will not lose any depth since you will always be operating as deeply as soil conditions permit.
19 produced by the GT Ax 550 as it scans. Multiple touches and releases are necessary to increase or decrease threshold by one Upper Scale segment at a time. Y ou can search silently or at any level of constant sound. It is recommended that you always operate the instrument at a minimum level of sound.
- AND + - Use these touchpads to adjust levels of threshold and depth and to move the cursor in the Upper Scale when setting the discrimination. 20.
21 HUNTING WITH THE GT Ax 550 There are no dials to turn and no controls to adjust. Just take the handle of your GT Ax 550 and lower the searchcoil to a level of about one foot above the ground. Press and release the POWER touchpad. After you hear two beeps, the GT Ax 550 is ready for detecting in Mode B, which is a factory pre-set COINS mode.
T arget Identification T arget identification of the last target over which the searchcoil passed will be indicated on the Upper Scale of the graphic display .
23 cannot maintain detection sound with the searchcoil held completely still above your target. This is called manual pinpointing and for many treasure hunters proves completely satisfactory . 2. Electronic Pinpointing Precise pinpointing is an important capability of your GT Ax 550 .
Y ou can also watch the Upper Scale illuminate from right to left to indicate signal strength. The maximum reading attained toward the left will indicate exact target location.
25 of digging targets, depending on the grass, soil conditions, etc. Always make as small a hole as possible. It is quicker , requires less work and makes refilling easier. Y ou should always fill your holes. Proper Scanning T echniques Swing the searchcoil back and forth in front of you in a straight line.
The Upper Scale of the graphic display will indicate a detected target. This indication will remain for five seconds or until a new target is detected (whichever comes first). The T arget ID Guide located above the Graphic Display will help identify your detected target.
27 signal as you scan one way and no response when scanning from the other direction. With Experience After you have used the GT Ax 550 for only a short time, you will be surprised at how proficient you have become with it.
JUNK T ARGETS Y our GT Ax 550 , in its factory set B (Coins) detection mode, will not respond audibly to most junk items. Occasionally , you'll encounter targets that cause the detector to respond with a quick, sharp sound, not like the clear , strong signal of a coin.
29 MAKING ADJUSTMENTS When you first press the POWER touchpad, your GT Ax 550 is ready to hunt, in the B (Coins) operating mode with threshold, depth and discrimination preset at the factory . Any or all of these operating levels can be easily changed.
Relic hunters, prospectors and others may adapt one of these to hunt for specific targets. Any personal preference adjustments you have set in the GT Ax 550 with the various operating functions will be retained when the detector is turned off.
31 Mode A (Zero Discrimination) Y ou will want to hunt in this detection mode, which is preset with no discrimination, when searching for caches or deep relics. Y ou may also wish to hunt in this mode when hunting in areas with many targets spaced closely together .
Setting Discrimination (Selecting Notches) Using only the discrimination of its two factory-set operating modes, the GT Ax 550 will more than satisfy the requirements of almost every treasure hunter .
33 There are two ways to set discrimination. First method: Press the (+) and (-) touchpads to position the blinking Upper Scale cursor above the Lower Scale segment corresponding to the particular target to be detected or ignored. If the segment is displayed, that particular target will be detected.
Note: Each time the detector is turned of f, the accept/reject discrimination selections will be retained in both modes. All selections will be lost when you return your detector to the factory set detection calibrations by pressing and holding the POWER touchpad for 10 seconds or until it beeps.
35 Special Note on Settings If you are ever unsure about the settings of your detector , simply press and hold the POWER touchpad for 10 seconds, or until the detector beeps, to restore the detector to the factory set B (Coins) mode.
BENCH TESTS Bench T ests enable you to test typical trash items and to learn about the discrimination capabilities of the GT Ax 550 before taking it into the field or trying to set your own discrimination notches.
37 represents true non-discrimination operation. 2. Use the Last Mode touchpad to select the alternate detection mode with its factory preset B discrimination notches. On your graphic display , Mode B will be illuminated. Bring the same targets across the bottom of the searchcoil and listen for the sound to increase when each item is scanned.
TEST PLOT CONSTRUCTION As you operate and use your GT Ax 550 , you will quickly grow more proficient in its use. It is recommended that you build your own test plot. Bury several items, including a nail, a piece of foil, a pull tab, a bottle cap and several coins at depths ranging from one to four inches.
39 HEADPHONE JACK The headphone jack on the GT Ax 550 is located at the rear of the removable battery pack under the armrest. Headphones are a valuable accessory for any metal detector to mask interference from outside noise. They permit you to hear small and deep targets that might be missed when using only audio from the detector speaker.
BA TTERIES The GT Ax 550 is equipped with two battery packs, each holding four standard AA batteries. The detector is also designed to use rechargeable batteries (Ni- MH).
41 The GT Ax 550 should operate 25 to 35 hours with carbon or alkaline batteries. Rechargeable batteries will offer slightly less time, depending upon the type used. These estimates are for speaker operation. Operating with headphones will extend battery life.
5. Press out the old batteries from the holders. 6. Install the new batteries. Carefully observe polarity of the batteries and place them in the holders. 7. Replace the holders in the detector . It is important that you make certain that the rivet on each battery holder is visible in the center of the battery case.
43 It is recommended that you remove the batteries when the detector is not in use, particularly for a period of several weeks. Always take the four batteries out of each holder when storing them. Y ou can then reinsert the empty holders into your detector to prevent their being misplaced.
The 9"x12" PRO formance— Use to increase detection depth and scanning width for hunting a broad target range. Part No. 2220700 The 4.5" Super Sniper ™ —Use in trashy locations or in tight places where a larger searchcoil will not reach.
45 MAINTENANCE Y our GT Ax 550 is a sensitive instrument built to withstand rugged treatment in the outdoors. Use your Garrett detector to the fullest extent, yet always protect and handle it with reasonable care.
SPECIALIZED HUNTING For literature that will explain more about the various types of hunting possible with your GT Ax 550 see the RAM Books section (page 53). Although it has universal capabilities, the GT Ax 550 has been designed primarily as a coin hunting metal detector .
47 Move your searchcoil across one type of these pieces of trash metal. Watch the target ID cursor for its response and push the ACCEPT/REJECT touchpad.
Since the 550 is a motion detector , it is capable of finding only somewhat larger nuggets (at least BB size). It must be emphasized that prospectors using the GT Ax 550, or any other quality detector , usually prefer to operate in the Zero Discrimination Mode.
49 SERVICE AND REP AIR In case of difficulty , read this Owner's Manual thoroughly to make certain your detector is not inoperable due to manual adjustments (Press and hold the POWER button for ten (10) seconds to return to the factory recommended settings).
Y ou have carefully packed the detector in its original shipping carton or other suitable box. Make certain that proper insulation or packing material is used to secure all parts. Do not ship stems or headphones unless they are part of the problem. Be certain to return all coils.
