A: This GLL40-20G has 1/4"-20 mounting thread. If your camera tripod has the same thread size, it will work. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.
A: To be clear, this is a laser level, not a laser tape measure. The 40’ designation is its effective range of use. This has no measuring capabilities. And yes it has a threaded connection for mounting on a tripod.
A: Hi there! The GLL40-20G has a mounting thread of 1/4-20. However, this tool is not a measuring tool. This is a self-leveling tool that you can still attach to the pole system. Also, there's nothing to transmit via Bluetooth, as this tool does not display measurements. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.
A: The range of the GLL40-20G is up to 40 ft, which means from middle to left is 20 ft and from middle to right is also 20 ft., so that makes it 40 ft. That's also the same from up and down (ceiling/floor range). For more information, please call 1-877-BOSCH99 (1-877-267-2499) from 7 a.m. to 7 p.m. CST, Monday through Friday.
