Wireless Optical Sensor WS-M02

Fixed into the barrel of a 9mm pistol, this device very accurately measures the weapon’s alignment while aiming and actuation of  the trigger mechanism. The optical sensor automatically determines the distance to the electronic target. The software allows for automatic calibration of the sensor relative to the weapon’s line of sight, so there is no need to adjust the weapon’s sights. The sensor also automatically compensates for any tilt in the weapon! The optical sensor has a two-way infrared connection to the electronic target.
The sensor has a built-in battery (1.5V, SW393SR).
The battery life is approximately 30 hours (approximately 136,000 shots with an average shot time of 3 seconds).
When not in use, the sensor automatically switches to power-saving mode. Weight: 6 g.
