Features With your metal detector, you can hunt for coins, relics, jewelry, gold, and silver just about anywhere. The detector is versatile and easy to use. The detector’s features include: LCD Display—shows the probable type of metal with an arrow, the depth of the target, DISC/NOTCH range, the level of sensitivity, the operating mode, and low battery indication.
PREPARATION ASSEMBLING THE DETECTOR Assembling your detector is easy and requires no special tools. Just follow these steps. 1. Turn the stem’s lock nut clockwise until it loosens. 2. Lengthen or shorten stem so that when you stand upright with the detector in your hand, the search coil is level with and about 1/2 to 2 inches above the ground with your arm relaxed at your side.
7. Loosen the knob at the search coil’s end, then adjust the search coil to the desired angle so that it is parallel with the ground. Then tighten the knob. Caution: Do not over-tighten the search coil or use tools such as pliers to tighten it. 8.
time the internal speaker disconnects. 2. Set the VOLUME to the desired setting. headphone Listening Safely To protect your hearing, set the volume to the lowest setting before you begin listening, adjust the volume to a comfortable level. Do not listen at extremely high volume levels. Extended high volume listening can lead to permanent hearing loss.

DISPLAYS The target indicator includes target icons and LCD displays and is located at the top of the detector. It can indicate different types of coins, gold, silver, etc. When the detector detects an object, an arrow appears below the target icon of the probable type of metal being detected and also displays the depth of the target.

tone for brass or silver items. Note: When you set the detector to DISC or NOTCH mode, the detector sounds a medium or high tone when it detects highly oxidized iron. An arrow appears in medium or high tone area. Depending on the alloys used to make them, about 15 percent of gold rings cause the detector to sound a medium tone.
Note: When you operate in this mode, only SENS. control will function, DISC. Or NOTCH controls will not. To adjust the sensitivity, first press SENS and UP to increase the sensitivity, then press Dn to decrease it. a. DISC—used for target discrimination. You can set the target range from MAX to MIN by pressing DISC/NOTCH and UP &...
metal of some kind in the floor, which might interfere with the objects you’re testing or mask the signal completely. 5. Slowly sweep a sample of the material you want the detector to find (such as a gold ring or a coin) 2-3 inches or more above the face of the search coil.
motion. Search coil Sweeping Hints Never sweep the search coil as if it were a pendulum. Raising the search coil while sweeping will cause false readings. correct wrong Sweep slowly. Hurrying will cause you to miss targets. Sweep the search coil from side to side in an arc line of 3 inches of motion and keep the search coil parallel with the ground.
sweep the search coil over the target a few times, the target is probably junk metal. False signals can be caused by trash-filled ground, electrical interference, or large irregular pieces of junk metal. False signals are usually broken or non-repeatable. Adjusting SENSITIVITY After you become familiar with how your detector works, it’s important to fine-tune the sensitivity to get a good effect.
If you detect patiently and correctly and practice these techniques, you’ll get satisfactory result. CARE, MAINTENANCE AND WARRENTY Your MD9100 metal detector is an example of superior design and craftsmanship. The following suggestions will help you care for your metal detector so you can enjoy it for years.

Handle the detector gently and carefully. Dropping it can damage circuit boards and cases and can cause the detector to work improperly. Use the detector only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, and damage the cases of the detector. Keep the detector away from dust and dirt, which can cause premature wear of parts.
