A: The GLL 2-20 G can not be used with a receiver as it doesn't have a pulse mode feature.
A: The GLL 2-20 G has a 1/4" mount at the bottom of the unit and hence, is compatible with 1/4" tripods.
A: If the batteries are almost empty, the battery indicator on the top of the tool will flash green.
A: No, only the horizontal laser line has a projection of 360°.
A: With regards to simplicity, we have removed the lock mode so that the user can not accidentally start working in lock mode, thinking the tool will be self-levelling.
A: Yes, it is possible. Instead of having the pendulum lock to hold the pendulum in place during slope mode, the pendulum would lean on the housing. This greatly simplifies the operation and avoids confusion between levelling mode and slope mode.
A: When the tool is out of level, in the beginning it will blink quickly for 2 seconds and then blink quickly every 5 seconds, so that the user can still work with it but knows that the tool is not self-levelling.

Good luck!
Which of these features does the GLL 2-20 G offer?
Recessed windows for additional protection of the laser windows. Rubberized housing for protection of the baretool and more stable positioning on ground. Intuitive keypad for easy laser mode selection and battery indications. Pendulum lock for protection of the pendulum during transport.How do I know that the batteries are almost empty?
There is no way to tell if the batteries are almost empty. If the batteries are almost empty, the battery indicator on the top of the tool will flash green. If the batteries are almost empty, the projected laser lines will flash green.How does the GLL 2-20 G get powered?
Through a 230 V power cable. With a Lithium-ion battery. With 4 x 1,5 V LR6 (AA) alkaline batteries.We hope you enjoyed it and now have a better understanding of the product!
