    Working Principle

    This handheld laser rangefinder utilizes the Time-of-Flight (ToF) principle for precise distance measurement. It emits a safe Class II laser pulse (610–690 nm, <1 mW), which reflects off the target surface and returns to the receiver. The internal high-precision sensor calculates the round-trip time of the laser beam, then automatically computes the distance using the constant speed of light, delivering fast, accurate, and repeatable measurements instantly.
