Product Abstract:

GMT GOLD Master Detector Tracks out the harsh ground found in gold-bearing areas to simplify the tough task of prospecting for gold

Product Description

Features:

Detectable distance: 0.1m - 1.5m

• Balance button: whether in manual mode or automatic mode, press the button with your finger, the instrument can instantly start to balance

• Iron Identification Menu: This menu on the display is used to display the percentage of iron metal. This information is very important. It determines whether the target being probed is worth digging.

• Iron metal “buzz”: If you choose this sound that sounds like “zipper”, when the instrument alarms, the probability of the detected metal target is determined to be iron metal is the highest

• Iron metal target analysis function: Press this function key and do not let go, the instrument will stop the trace scan. Each time the probe scans a metal target, the instrument analyzes the possibility of the target being iron metal. After the hand is released, the instrument will stop the analysis and restart the trace scan

• Tracking veins: The instrument displays mineral content in the ground. Gold is hidden in the veins, so the veins are tracked.

• Volume adjustment: You can adjust the volume of the instrument by yourself

• Power supply source: AA 5th battery, can support about 40 hours of work

• Probe disk: Configuring a powerful "DD" waterproof detection disk, greatly increasing the detection effect

• Operating frequency: 48KHz

• Operating CD-ROM: The original operating CD-ROM provided by the manufacturer can play a role in teaching

• Automatic balance: In the detection process, if the instrument encounters some disturbing factors such as mineralization reaction, it needs to use the fully automatic balance function to completely eliminate them. The instrument's display shows the value of ground mineralization recorded by the microprocessor. When detecting changes in the environment, the need to use the ground balance function allows the instrument to have a process of adaptation to the new environment

Assembly

Chapter 1 GMT Assembly

Assembly Instructions

1. Remove all parts from shipping carton and check the assembly page to make sure all parts are present.

2. Unlock "S" rod camlock and insert the reduced end of the center rod into curved "S" rod so that stainless steel spring clip buttons line up and lock into the holes in the curved "S" rod. Turn camlock to secure.

3. Fit the rubber washers between clevis/lower rod and searchcoil ears. Use only non-metallic washers, fiber bolt, and thumbnut, to secure loop to clevis/lower rod. Then insert into center rod so that stainless steel spring buttons line up and lock into one of the adjustment holes in the center rod. Turn Camlock to secure.

4. Unravel cable and wind the cable around the clevis and rod assembly, first revolution should be OVER the top of the rod with some slack before applying the cable retainer. This is done so that the search coil can be paddled backwards toward the rod without putting a strain on the cable. Wind cable firmly all the way to the handle toggle switch. Then plug connector into control box turn lock ring to secure. To secure cable, wrap velcro cable retainers around rod and cable, one near the searchcoil and one near the toggle switch.

5. Grip the instrument by the handle, with your arm in the elbow cup with strap secure, and sweep the coil over the floor. If the instrument fit feels uncomfortable, adjust the elbow cup by removing and repositioning the bolt/thumbnut and installing in one of the optional positions. If necessary, readjust clevis/lower rod length with the sping clip

buttons so that the searchcoil can be held near the floor without requiring stooping over.

6. Adjust the elbow cup strap so that it is loose enough for you to slide your arm in and out without loosening each time you want to set the detector down. Peel and stick elbow cup foam pads on the inside of the elbow cup, one on each side.

7. Install battery as described in the next section, decal facing down, with plastic tab and steel contacts facing toward inside of battery compartment.

8 It should be noted at this point that the detector may not work as expected indoors due to the high degree of metals ( nails, pipes, etc.) used in modern construction and the presence of electrical interference. It is best to tune and practice out-of-doors to ensure stable, predictable results.

Standard Battery Holder

1. The standard battery holder holds eight “AA” cell batteries. Alkalines are recommended for use with this model. During normal searching conditions you can expect about 40 or more hours of hunting time from one set of eight alkaline

batteries.

2. Non-alkaline batteries can be used in this holder. When non-alkalines or rechargeable “AA” cells are used, detecting time (before replacement/ recharge) may be reduced to about 30-35 hours.

3. Once the batteries become weak, the beep over metal targets will be reduced in volume. Shortly thereafter, the instrument will no longer respond to metals. The Audio-Boost toggle has a battery test position in the spring-loaded down position. Battery level is noted on meter.

4. The battery compartment opens by gently pulling down on the front of each of the two

latches (on the bottom of the control box) releasing the catch and hinging open the door.

Using the

Standard Battery Holder

1. Slide open the battery holder lid (decal side of battery holder) by applying gentle upward pressure on the tab of the door so that it unlocks. Slide the door away from the battery box exposing the cell positions.

2. Remove any old cells from the holder. Note the (+) and (-) positions of each cell and the (+) and (-) for each position marked inside the cell tray. Install new “AA” cells noting carefully the correct (+) and (-) positions. If the cells are installed incorrectly, the detector

may require service by an Authorized Service Center.

3. Slide the door closed so that it snaps securely.

4. Insert the battery holder into the detector so that the decal is facing down, with the battery holder door tab and metal contact points facing toward the inside of the battery compartment. Close the battery compartment door and secure the two latches on the bottom of the case. Hook the front of each latch first, then press down on the rear.

Rechargeable Battery(Opt.)

A rechargeable battery system is not standard equipment with your GMT, however, high quality systems are available.White's rechargeable battery #802-5211, and charger #509-0022 are recommended and offer quick charge and overnight charge options.

Rechargeable batteries deliver fairly constant voltage until they're nearly dead. If you use them until they are dead, they will deteriorate more quickly than if you only use them till their voltage starts to drop significantly. Therefore, rechargeables should be taken out of service and recharged as soon as you notice the battery life starting to fall substantially below the bargraph position that corresponds to fully charged batteries. The White's Rechargeable Nicad battery will not provide the same amount of continuous use as a full set of Alkaline batteries.

When the Battery Test toggle is pressed downward, battery condition is indicated on a bargraph on the LCD display, and by audio pitch. If the batteries are not fresh, audio loudness on big targets will not be as great, but there will be no loss of sensitivity or

performance. Since Nicads and Alkalines die at different voltages, it is not possible to have a Low Bat & Bat OK indication, however the bargraph fills to the right on a fully charged battery pack. As the battery life drops you will note the bargraph diminish. When the bargraph gets close to the left it is time to replace or recharge. At this point the

bargraph changes to a message, "SORRY! LOW BATT". Typical battery life will be in the neighborhood of 40 hours or more. Non-rechargeable batteries will start to drop in

voltage as soon as they are put into use and then slowly diminish in voltage till they die. The Nicad rechargeable battery pack, however, will diminish voltage very slowly, in somewhat of a flat line and then when they begin to lose their charge, the voltage will drop like a rock. Headphone use prolongs all battery life. Battery life will vary a great

deal with temperature, number of target signals, battery type, brand, and shelf life. Non-rechargeable batteries may be used until the display indicates "dead battery", or the audio loudness on large targets is diminished more than you like. When traveling far from home it is always a good idea to carry 8 extra penlight alkaline batteries with you as well as an extra empty battery holder.
