【FEATURES】 1.Balanced line can eliminate the influence of mineralized reaction, improve the depth and exact rate of valid detection. 2.The function of distinguishing black and colored metals. 3.Use intelligent operating system. 4.Adopt high-strength ABC material to encapsulate, own light weight, long life 5.Identify sound by earphone 【PURPOSE】 ◆This product adopts sound alarm and instrument display, the depth of detection is related with the area, shape and weight. In general, more area, larger quantities, at the same time, with bigger detect depth; whereas, less area, smaller quantities, with smaller depth. ◆Products: Use a standard aluminum board embeds dry clay, whose size is **0mm***0mm*5mm, the maximum detect depth is **2.5m. [SPECIFICATIONS] Model MD****2 Signal frequency **7 KHz Power 8pcs 1.5v Batteries in Series Shooting frequency 6.*9 KHz Detecting depth (Max) 1.5m Gross weight 3Kg ▲ the specification is under standard test condition. The sensitivity depends on the working condition. We have no responsibility that metal chips come out after detecting under non-standard condition.
