Basic Parameters Search Range: Up To 1000 Meters Detection Depth: Maximum 15 Meters Signal Frequency: Maximum 433MHz Operating Instructions 1. Hold the instrument, very slowly in an arc to scan, together with the rotation of your own. At this time, the explorer elbows should always be close to the sides of the body, about 40 degrees to 60 degrees on the turn can be. Note: the explorer must slowly rotate, and to maintain a stable body. 2. Standardize your scanning action. First of all, let the receiving antenna is correctly extended open back. Make the receiving antenna in front of you, and your body into 90 degrees open, not to the left and right sides of the deflection. 3. When the antenna is aligned with the object, the instrument will be sure to live, although you continue to explore across the approach. When you feel that this determination is effective, you will remember this direction. Then, move the instrument to the left or right about 10 meters, and repeat the process of determining the direction described above. Observe this time to determine the direction, the intersection of the two directions is the buried position of the object. 4. If you feel that the specific position measured just now there is still a certain offset, you can determine from another point of view. If the target is within 10 meters, you will slowly and smoothly follow one of the designated routes. When you pass the object and is directly above it, the instrument's antenna will shake both sides. Then the measured position will be very accurate. (Please refer to the manual for specific operating instructions) The product comes with demagnetization function (as long as the probe through the receiver near the ferrous metal, alarm three times, you can demagnetize)
