ATX880 Waterproof Portable Underground Metal Detector Gold Hunter 15" Search Coil Large LCD Screen

ATX880 Waterproof Portable Underground Metal Detector Gold Hunter 15" Search Coil Large LCD Screen

Description:
Underground metal detectors are specifically designed to find the smallest gold ore in the highest mineralized soil. It can detect metal objects such as gold. Unlike other specialized gold detectors, this metal detector is a versatile detector which is ideal for coinage and relic hunting. Many treasure hunters like to use it to hunt treasures because it is very convenient.

Please pay attention to these parts in the user manual:
1.ELIMINATION
Reference to a metal being "eliminated" means that the detector will not emit a tone,nor light up an indicator,when a specified object passes through the search coil’s detection field.
2. DISCRIMINATION
When the detector emits different tones for different types of metals,and when the detector "eliminates" certain metals,we refer to this as the detector "discriminating" among different types of metals.
Discrimination allows the user to ignore trash and other undesirable objects.
3.RELIC
A relic is an object of interest by reason of its age or its association with the past. Many relics are made of iron, but can also be made of bronze or precious metals.
4.IRON
Iron is a common,low-grade metal that is an undesirable target in certain metal detecting applications. Examples of undesirable iron objects are old cans,pipes,bolts and nails.
Sometimes,the desired target is made of iron. Property markers,for instance,containiron. Valuable relics can also be composed of iron;
cannon balls, old armaments, and parts of old structures and vehicles can also be composed of iron.
5.FERROUS
Metals which are made of, or contain, iron.
6.PINPOINTING
Pinpointing is the process of finding the exact location of a buried object.
Long-buried metals can appear to the eye exactly like the surrounding soil,and can therefore be very hard to isolate from the soil.
7.V.C.O.
Meaning voltage controlled oscillator, the V.C.O.audio method causes both the audio pitch and the volume to rise as signal strength increases. V.C.O. improves the user' s ability to interpret a target' s size and depth. Very weak signals (for small or very deeply buried objects) have the faintest volume and the lowest pitch.
Larger objects, and those closer to the search coil, will induce a higher volume and higher pitch sound.
8.GROUND BALANCE
Ground Balancing is the ability of the detector to ignore, or "see through" the earth' s naturally occurring minerals,and only sound a tone when a metal object is detected.
9. Target ID - Different types of metals are classified along the arc at the top of the screen on a 0-100 scale from left to right. A 2-digit numerical reading is also provided in the middle of the display for more precise target identification in Discrimination Mode.

Detail about Using Key:
TARGET PINPOINTING
After you have identified a target using Discrimination Mode,press-and-hold the PINPOINT button to identify the target’s exact location. This technique can yield more information about the target’s shape and size and also find its exact location to facilitate extraction.
Pinpoint as follows:
1. Position the search coil just barely off the ground, and to the side of the target.
2. Now move the search coil slowly across the target; you can locate it by the sound. The target is located directly under where the sound is loudest.
Narrow It Down:
1. To narrow the response further, position the center of the search coil near the center of the response pattern, but not directly over the center.
2. Release the PINPOINT button.
3. Press-and-hold PINPOINT button again.
4. Repeat this narrowing procedure to narrow the field of detection further.
Note: Depth indication is less accurate after narrowing.
