WHITE’S ELECTRONICS COINMASTER 2900 SERIES 3 (01) PDF DOCUMENT

To assemble your WHITE’S ELECTRONICS COINMASTER 2900 SERIES 3, follow these general steps based on the parts identification diagram:

1. The detector consists of a Control Box, a 2-piece rod, and an 8″ Concentric Loop.

2. Insert the outer rod section into the rod section located under the Control Box. This connects using a double button spring clip.

3. Slide the inner rod section into the outer rod section. This connects using a single button spring clip.

4. Attach the 8″ Concentric Loop to the end of the inner rod section. Use the provided loop bolt, washers, loop isolator, and thumbnut to secure it.

5. Insert the 9-volt battery into the Control Box.

The POWER/VOLUME control on your WHITE’S ELECTRONICS COINMASTER 2900 SERIES 3 has two primary functions:

1. It turns the detector ON and OFF. The “OFF” position is fully counter-clockwise.

2. It controls the maximum level of the audio tone. If the VOLUME is set below the threshold level, targets will not be heard.

The TUNER sets the detector’s THRESHOLD, which is a barely audible audio tone that represents the detector’s maximum operating sensitivity. To set the THRESHOLD:

a) Set all controls to the preset “P” mark.

b) Hold the detector so that its loop is in the air, straight out in front of you at waist height.

c) Press and hold the PUSH BUTTON and turn the TUNER to the right until the tone is barely heard. Release the PUSH BUTTON.

The THRESHOLD needs to be re-set whenever any of the other controls are adjusted. To re-set the THRESHOLD, raise the loop waist high, press and release the PUSH BUTTON.

The TR/DISCRIMINATE mode on the WHITE’S ELECTRONICS COINMASTER 2900 SERIES 3 can distinguish between desirable and undesirable targets, but it will not neutralize ground mineralization at the same time. It is excellent for coinhunting, relic hunting, prospecting, and beachcombing.

To tune the detector in this mode:

1. Tune to THRESHOLD as previously described.

2. Lower the loop to approximately 1/2″ above the ground.

3. Press and release the PUSH BUTTON to re-set the THRESHOLD.

4. Search with the loop level to the ground and as close as possible. Note that if the loop is tilted or lifted, the tone may change due to ground variations.

5. The DISC control is used to distinguish between targets (see DISC control instructions). When searching in this mode, the loop does not have to be in motion.

The TR/DISCRIMINATE mode provides extended Ground Balance for extreme conditions like saltwater beaches and heavily mineralized ground. The DISC control is used to neutralize the effects of this mineralization. To use your WHITE’S ELECTRONICS COINMASTER 2900 SERIES 3 for this purpose:

1. Set the detector’s THRESHOLD.

2. Set the DISC control to 1.

3. Lower the loop to the ground. If the tone does not change, the unit is Ground Balanced.

4. If the threshold tone changes, raise the loop to waist height. Turn the DISC control SLIGHTLY RIGHT if the tone INCREASED, or SLIGHTLY LEFT if the tone DECREASED.

5. Press and release the PUSH BUTTON. Lower the loop back down to the ground and note any change in tone.

6. Repeat step 4 and 5 until there is no change in tone between the air and the ground.

NOTE: Press and release the PUSH BUTTON after each adjustment to the DISC control. If you have trouble, you may be over some metal; move to another spot and repeat the steps.

The PUSH BUTTON retunes the instrument to the threshold. To regain threshold, press and release the PUSH BUTTON. This must be done after any control has been adjusted.

The DISC (Discrimination) control on your WHITE’S ELECTRONICS COINMASTER 2900 SERIES 3 helps distinguish between desirable and undesirable targets. You set the discrimination point with the knob slightly below the desired targets.

The audio response of targets ABOVE the DISC set point will produce louder tones. Targets below the set point will make the tone go away.

EXAMPLE: With the DISC control set at “5”, nickels and all other US coins will produce a louder, solid tone. Nails and other junk will cause the tone to go away.

Desirable targets may include coins, rings, and gold. Undesirable targets may include pop tops, pull tabs, and nails.

Important Considerations:

1. Discrimination should be used only as necessary to avoid passing over desirable targets. For example, when the DISC control is set high enough to reject pull tabs or screw caps, US nickels, some thin rings, and other desirable items may also be rejected.

2. Increasing the levels of discrimination reduces depth capabilities.

It is recommended to test the unit with a variety of desirable and undesirable targets before using it in the field.

The GROUND ADJUSTMENT control on your WHITE’S ELECTRONICS COINMASTER 2900 SERIES 3 controls the detector’s sensitivity to ground mineralization.

• In mineralized ground, decrease the GROUND ADJUSTMENT by turning the control counter-clockwise (towards HIGH MINERAL).

• In ground with very little mineralization, increase the GROUND ADJUSTMENT by turning the control clockwise (towards LOW).

As the GROUND ADJUSTMENT is increased, the detector becomes more sensitive to both metals and ground mineralization.

The LOW BATTERY ALERT light on your WHITE’S ELECTRONICS COINMASTER 2900 SERIES 3 emits a soft, constant glow when the detector is ON. When the batteries need replacing, the light will glow noticeably stronger and brighter.

The 1/4″ HEADPHONE JACK allows you to listen to the audio signal on mono headphones. Using headphones provides two main benefits:

A) It disconnects the speaker output.

B) It reduces battery drain.

1. Always keep the loop flat and parallel to the ground. When the loop is raised, depth penetration is decreased.

2. Swing the loop in front of you while searching. Each swing may cover an area from 4-6 feet in width.

3. The loop should be passed along the ground in smooth, even swings. It does not have to be swung quickly.

4. When a target is detected, sweep it from several directions and note the audio response to determine if it is worth recovering.

To pinpoint a target for ease of recovery, you should “X” the target. Sweep the loop over the target area to find the line of maximum signal (Axis A). Then, sweep the loop perpendicular to that first line to find the second line of maximum signal (Axis B). The object will be at the center of the “X” where the two lines intersect.

The WHITE’S ELECTRONICS COINMASTER 2900 SERIES 3 uses a 9-volt battery. To replace it, proceed as follows:

1. Open the battery compartment door at the rear of the control box.

2. Remove the battery from the clip. Carefully disconnect the terminal lead and replace the battery.

3. Reconnect the terminal lead and replace the new battery in the clip.

4. Close and latch the battery compartment door.

A standard battery should last between 10-12 hours under normal conditions.

Please observe the following cautions for the batteries used in your WHITE’S ELECTRONICS COINMASTER 2900 SERIES 3:

1. Do not dispose of batteries in a fire.

2. Protect the battery from being shorted. Burns may result and the battery may be damaged.

3. Non-rechargeable batteries may explode if they are recharged.

4. Store batteries in a cool, dry place.

CLEANING: The loop and rod are waterproof and can be cleaned with fresh water and a mild cleanser. Dry the instrument thoroughly after cleaning. CAUTION: The instrument case is not waterproof. Water entering the case will damage electronic components.

WEATHER CONDITIONS: Protect your detector from extreme cold, as freezing can damage electronic components, the case, and/or batteries. Excessive heat can also cause damage; never leave it in direct sun. If left in a car on a hot day, cover it and leave windows slightly open for ventilation. If you operate it in the rain, protect the instrument case from water entry.

SALT WATER: Salt water is very corrosive. If your detector is exposed to salt water, rinse it immediately and thoroughly with fresh water, being careful not to allow water to enter the instrument case. Wipe it with a cloth dampened with fresh water and dry it thoroughly.

ADDITIONAL PRECAUTIONS:

a. Avoid dropping your detector.

b. Do not use any lubricants on any part of your metal detector.

c. Avoid sharp jars to the loop.

d. Do not allow batteries to corrode inside the instrument.

e. Do not alter or modify your instrument during its warranty period, as alterations will void the warranty.

The serial number for your WHITE’S ELECTRONICS COINMASTER 2900 SERIES 3 is located on the silver tag inside the battery compartment. The code number is on the white tag.

It is strongly urged that you adopt a code of ethics to preserve the environment and the rights of treasure hunters.

• Before searching, check the laws, ordinances, or regulations for hunting on publicly owned sites and abide by the rules.

• If the area is private property, get written permission from the owner to search. Offering to share finds or search for a lost item for the owner may help.

• ABOUT DIGGING: In lawn areas, limit the hole size to a maximum of two inches in diameter, cutting a plug of sod that can be easily replaced. After you retrieve your finds, carefully fill the hole. Holes are both unsightly and dangerous.

• Detectors for large, deep objects should be used with discretion, never in lawn areas, and with careful judgment elsewhere. Consider the scar you may leave before digging.

• Adopting these attitudes can enhance the public’s opinion of treasure hunters, ensuring more areas remain open for detecting. You can also increase your reputation by volunteering to carry out and dispose of any trash you find.
