Perfect for anyone wishing to get more accuracy and proficiency on the putting green, Fix your putt in seconds

Simple to install and operate. Two modes:
INT (automatic mode) once you press the power button, the laser will last 10 seconds and then power off automatically
CON (continuous mode) once you press the power button, the laser beam will stay on (will last about 35-40 minutes, then the voltage will decrease, the laser will also become weak) Turn OFF for 1 hour, and then it should be normal again. (We suggest that CON mode is only used to align the sight)
