The Bosch GLL3-330C is an all-in-one leveling and alignment line laser that revolutionizes one-person job setups. It projects three laser chalk lines in 360-degree laser planes - one horizontal and two vertical. With Bluetooth connectivity, you can conveniently control the laser's setup from across the room using your smartphone and the free Bosch Leveling Remote App. This laser offers dual power options. You can use the included Bosch 12V Max Lithium-ion battery for extended runtime or four AA alkaline batteries. It has a working range of up to 200 feet in diameter, and with the pulse mode and an optional LR 6 or LR8 receiver, the range extends up to 330 feet in diameter. The VisiMax technology enhances line visibility, and the CAL Guard ensures calibration accuracy. Its robust over-molded construction makes it suitable for rainy or dusty jobsites. Key features include built-in VisiMax technology that monitors power consumption to boost line visibility and battery life, Bluetooth connectivity for remote control, a free Bosch Leveling Remote App that allows you to turn on/off the laser and receiver, select laser planes, adjust line visibility, and get battery and level alerts. It also has an upgraded diode with a brighter beam, a smart pendulum system that self-levels and indicates out-of-level conditions up to ±4°, a manual mode for locking lines at any angle, a BM 1 positioning device for easy setup, CAL Guard for calibration monitoring, and an IP54-rated jobsite-tough over-molded construction.






Using the Bosch GLL3-330C is a breeze. First, choose your power source. You can either use the included Bosch 12V Max Lithium-ion battery for longer use or four AA alkaline batteries if you need a quick option. Once powered on, if you're working within 200 feet in diameter, you can use the laser in normal mode. For longer distances or in bright light, switch to the pulse mode and use an optional LR 6 or LR8 receiver. To control the laser, download the free Bosch Leveling Remote App on your smartphone. Through the app, you can turn the laser on and off, select which laser planes you want to use, adjust how visible the lines are, and get alerts about the battery and the level. The smart pendulum system will self-level the laser, but if you need to use it at a specific angle, switch to manual mode to lock the lines. When setting up, use the BM 1 positioning device. It can clip to different surfaces, stand on the floor with its retractable feet, or be mounted to drywall or wood with screws. As for maintenance, keep the laser clean from dust and debris, especially after using it in a dusty jobsite. Check the calibration regularly with the CAL Guard feature. If the laser has been dropped or exposed to high heat, make sure to check the calibration as well. Store the laser in a dry place when not in use to keep it in good condition.
