▲ Induction method: detection of ultra-low frequency electric waves emitted by the human heart; non-induction target: any animal other than the human body is not detected for the time being; detection frequency: ultra-low frequency of 30Hz or below

▲ Vertical detection: +/- 60 degrees open space 120 degrees (60 degrees above and below 80 degrees in the building) up and down 40 degrees each horizontal detection +/- 2 degrees (2 degrees left and right); hand-held operation: weight 1 kg Or below

▲ Detection distance: 0-20 meters for short antennas; 0-500 meters for long antennas Equipped with American standard three A-level laser light spots, providing operators to find the direction of the detection rod

▲ Target lock function: When detecting the electric field generated by the low-frequency electric wave emitted by the human heart, the detection lever will automatically lock the electric field. When the human body moves, the detection lever will follow.

▲ Working time: If the laser light spot is used for 12 hours of continuous work, the auxiliary operation is 2 hours. Passive reception detects the direction of the remote weak heartbeat dielectric field and only detects surviving humans without interference from other animals. It can pass through various obstacles such as steel plates, cement, composite materials, trees, etc., so that the detection distance can reach more than 1 km on the surface of the open space up to 500 meters in water.

▲ Effective distance: DKL is equipped with two different detection rods. The long-range detection rod can detect 500 meters and the short distance is 20 meters. When DKL encounters obstacles such as reinforced concrete walls, steel plates, etc. The detection distance will be reduced, and the laser light can increase the detection distance by 10%.

▲ Vertical angle: when there are no obstacles, 60 degrees up and down, a total of 120 degrees; when there are obstacles: 40-50 degrees up and down, a total of 80-100 degrees; horizontal detection angle: 2 degrees left and right, a total of 4 degrees
