Extended 3. high volume listening can lead to permanent hearing loss. Do not wear headphones while 4. operating your detector near high- traffic areas. Be safe and pay attention to traffic. Functions and Indicators VOLUME - Sets the sound level. TUNE - Sets the sensitivity level of the unit. NOTE: Set to the lowest setting when away from any metal objects. MODE - Sets the unit to two modes: OPERATE and BATT TEST. Red Tuning Button - Press this button and set the TUNE dial to 0 to properly balance the Detector. DISCRIMINATION - Adjustment knob for metal-type identification. View Meter - Registers signal strength when a metal is detected. NOTE: The Metal Detector must be properly balanced before testing or operation. To balance the Metal Detector, slide the MODE Switch to OPERATE and press the Red Tuning Button (2) on the Handle. Rotate the TUNE dial until the indicator on the View Meter (8) reads “0”. Release the Red Tuning Button. If the indicator is slightly to the left or right of the “0,” readjust the TUNE dial until the Metal Detector is properly balanced. You will hear a clear “hum, hum” tone. IMPORTANT! The above balance adjustment may have to be made multiple times during use. This does not mean the Metal Detector is malfunctioning. Red Tuning Button (2) MODE Switch Figure 3 Before Getting Started Before beginning an outside search, you must test the unit with samples of metal. Use the following: an iron nail• a five-cent coin (nickel)• a one-cent penny (zinc coin, after • 1982) a silver quarter• Place the Metal Detector on a wooden or plastic table with the Search Coil face up. Make sure the table is away from TVs, computers, or any device that can cause interference. See Figure 4. NOTE: Be sure to remove any watches, rings, or other metal objects on your fingers and hands. Set Mode Switch to OPERATE and VOLUME dial to mid-point. The Metal Detector may sound a tone or be silent. If not already done, adjust the balance of the Metal Detector. (See the “NOTE” under “Functions And Indicators” on previous page.) Once Detector is balanced, perform a test of a sample to adjust the controls to differentiate (“discriminate”) between ferrous (iron) metals and non-ferrous (metals. To find ferrous metals (to 1. “discriminate” iron), set the DISCRIMINATION dial to MIN. See Figure 5. Hold the iron nail sample close to the 2. Search Coil. The indicator on the View Meter will swing to the left and the “hum, hum” tone will be lighter. Bring the other coins close to the 3. Search Coil. The indicator will swing to the right and the “hum, hum” sound will become louder. To find non-ferrous metals (such as 4. nickel), set DISCRIMINATION dial to midpoint setting. See Figure 6. Figure 5 Figure 4 Figure 6 Reset the balance of the Metal 5. Detector. Bring the nickel coins close to the 6. Search Coil. The indicator will move to the left and the sound will get softer. Bring the silver coins close to the Search Coil. The indicator will move to the right and the sound will get louder. The midpoint is the discrimination setting for nickel. For easy reference: 7. For ferrous metals, the indicator will always move to the left and the sound will grow softer when the DISCRIMINATION dial is set to any location. For silver, the indicator will move to the right and the sound will get louder when the DISCRIMINATION dial is set to any location. When DISCRIMINATION is set to MIN, only ferrous metals will make the indicator move to the left. All other samples will make the indicator move to the right. When DISCRIMINATION is set to MAX, only silver-based metals will make the indicator move to the right. All other samples will make the indicator move to the left. Different metals have their own discrimination position. This is important to know, as all metals appear in the form of alloys and their composition can be complicated. Use the above sample test as a general reference guide to help determine the composition of a buried metal. By turning the DISCRIMINATION dial from MIN to MAX, you can determine the type of a buried item. From MIN to MAX, the order of metals goes: - Iron - Nickel - Gold - Brass - Zinc, - Copper - Silver (Aluminum) NOTE: The discrimination position of aluminum is close to silver. NOTE:8. When DISCRIMINATION is set to MIN, the Metal Detector does have greater sensitivity as compared to when it is set at MAX setting. General Operating Instructions Once all the proper tests and adjustments have been made, the Metal Detector is ready to be used outdoors. NOTE: Make sure Metal Detector is properly balanced before use. NOTE: Be sure to keep the angle between the Search Coil and the Detector’s Lower Leg at about 140° See Figure 7. When first searching, set the Mode 1. button to OPERATE. Adjust the VOLUME to the desired 2. level. Figure 8 3. Sweep the Search Coil (27) slowly back and forth in an arc, keeping it about 1/2” to 2” from the ground. See Figure 8, above. If you hear a beeping noise or see 4. the needle jump to the r...
