Resumen del manual
Text Box: Notes: ? The search coil will not detect without motion. You must move the object since you are not sweeping with the detector at this time. ? If you are suing a coin, the detects it more easily if you hold it so a flat side is parallel with the flat side of the search coil (not the edge). If the detector detects the material, it sounds a tone and the pointer moves to the left (ferrous) or to the right (non-ferrous) while the detector determines the type of meal it is detecting. If the detector does not detect the material, check the battery power and verify that the search coil is properly connected. Also, you might need to fine-tune the detector (see “Fine-Tuning the Detector” on Page 10). Text Box: TESTING AND USING THE DETECTOR To learn how the detector reacts to different metals, you should test it before you use it the first time. You can test the detector indoors of outdoors. Indoor Testing 1. Remove any watches, rings, or other metal jewelry you are wearing, then place the detector on a wooden or plastic table. 2. Adjust the search coil’s angle so the flat part faces the ceiling. Note: Never test the detector on a floor inside a building. Most buildings have metal of some kind in the floor, which might interfere with the objects you are testing or mask the signal completely. 3. Rotate VOLUME to the 11 o’clock position. 4. Set DISCRIMINATION to its midpoint. 5. Move a sample of the material you want the detector to find (such as a gold ring or a coin) about 2 inches above the search coil. Text Box: PINPOINTING A TARGET Accurately pinpointing a target makes digging it up easier. Accurate pinpointing takes practice, and we suggest you practice finding and digging up small metal objects on your own property before you search other locations. Sometimes, targets are difficult to accurately locate due to the sweep direction. Try changing your sweep direction to pinpoint a target. Follow these steps to pinpoint a target. 1. When the detector detects a buried target, continue sweeping the search coil over the target in narrowing side-to-side motion. Make a visual note of the exact spot on the ground where the detector beeps. 2. Stop the search coil directly over this spot on the ground. Then move the search coil straight forward away from you and straight back toward you a couple of times. Make a visual not of the exact spot on the ground there the detector beeps. Text Box: Note: Each time you use the detector in a different area, you must adjust DISCRIMINATION. Each search location presents new challenges. FALSE SIGNALS Because your detector is extremely sensitive, trash-induced signals and other sources of interference might cause signals that seem confusing. The key to handling these types of signals is to dig for only those targets that generate a strong, repeatable signal. As you sweep the search coil back and forth over the ground, learn to recognize the difference between signals that occur at random and signals that are stable and repeatable. To reduce false signals when searching very trashy ground, scan only a small area at a time using slow, short overlapping sweeps. DETECTION HINTS No detector is 100 percent accurate. Various conditions influence metal detection. The detector’s reaction depends on a number of things: ? The angle at which the object rests in the ground ? The depth of the object ? The amount of iron in the object ? The size of the object Text Box: 6. Try finding other metal in the area. When you find a metal item, wait a few seconds after the tone stops before continuing, to allow the detector time to reset (or, press the red button on the handle to return the pointer to the center of the view meter). FINE-TUNING THE DETECTOR After you become familiar with how your detector works, you can fine-tune it to make it more selective in what it finds. Discrimination is the detectors’ ability to differentiate between types of metal. The detector’s DISCRIMINATION setting determines whether the detector will distinguish between different types of ferrous and non-ferrous metals. You can set DISCRIMINATION to minimum (fully counterclockwise), to maximum (fully clockwise), or anywhere in between. As you set DISCRIMINATION to higher levels, the detector first does not detect small pieces of silver paper, then thick foil, and finally metal objects like pull tabs from aluminum cans. Text Box: 3. Repeat Steps 1-2 at a right angle to the original search line, making an “X” pattern. The target should be directly below the “X” at the point of the loudest response. Note: ? If trash in an area is so heavy that you get false signals, slow your sweep speed and use shorter sweeps. ? Recently buried coins might not respond the same as coins buried for a long period of time because of oxidation. ? Some nails, nuts, bolts, and other iron objects (such as old bottle caps) oxidize and create a “halo” effect. A halo effect is caused by a mixture of natural elements in the ground and the oxidation creat...
