Brief introduction: New Max laser M3 with low speed velocimeter a kind of excellent performance, complete function of single doppler radar gun type, use of advanced digital integrated digital signal processing technology, superior signal processing, which can realize the ground moving target radial velocity measurement, wireless rf technology is easy to use, simple sense is good, special light in weight, flexible, quick reaction, most can be measured the speed of moving object, more suitable for mines, schools, enterprises, highways, railways, airports, ports and other places of various kinds of need for speed. Functional features: M3 speedometer USES polymer lithium battery, small volume and large capacity, the battery is successfully embedded in the handle, easy to use. The display screen is a 7-section 8-word digital tube, which is clearer and more suitable for display in the daytime and other strong light conditions. Moreover, it is very simple to operate, quick to respond, accurate to measure and complete to function. 1. Track and lock fast targets 2. Working in static mode, easy to use 3. It can show the target approaching or leaving 4. Clear and readable display 5. The speed value can be locked Technical indicators: 1.Working performance: (1) speed measurement accuracy: + / - 1km/h.
