1. Auxiliary putter practice, correct the wrong path, and improve the straightness and accuracy of the putter
2. Two laser sight use modes, automatic [IND] + uninterrupted power [CON]
3. Automatic mode [IND]: Press the purple button above the laser, and the laser head at the front of the push rod sight will emit a red laser (the laser will automatically turn off after 10 seconds)
4. Uninterruptible power mode [CON]: the laser emits red laser lines that are always on and not extinguished (used when adjusting the angle of the laser)
----- Note: After 30-45 minutes of continuous use in CON mode, the battery voltage will decrease. If the laser light becomes dark, please turn off the laser and place it in a safe place for about an hour. After the battery voltage rises, you can continue to use it. CON mode is not recommended for prolonged use
