As the first laser rangefinder in the industry to achieve full touch interaction, the product team has designed a simple and intuitive dynamic interaction page for LS5 to aist full touch buttons. Users can switch functions by simply sliding the screen up and down, left and right, and experience the measurement fun brought by black technology in play.Q: How about the endurance?A: Charge for 5 minutes and measure 500 times. The LS5 is equipped with a 280 mA lithium polymer battery. Through the ultra-low power chip design, it can measure 4000 times or 3000 meters at full charge. The TYPE-C interface can be easily charged with a mobile phone charger, a computer USB interface, etc.Q: Is laser harmful to human body during use?A: The laser source used by LS5 is a Cla II laser, and the power consumption is le than 1 milliwatt. Daily use will not cause any harm to human body. However, direct eye contact with the laser will cause short-term vision lo. Therefore, for safety reasons, it is strictly prohibited to directly shoot people/animals' eyes when using this product to avoid accidental injury.Q: How can the measurement be more accurate?A: When LS5 is used for daily measurement, try to keep the rangefinder stationary and not shaking, and do not block the head laser transmitting port and receiving port of LS5.
