Bosch dominates the laser measure market. Their GLM series ranges from the pocket-friendly GLM 20 (65-foot range, $30) to the Bluetooth-enabled GLM 50-27 CG (165-foot range, camera viewfinder). The GLM 30 is the sweet spot for most users: 100-foot range, +/-1/16" accuracy, fits in a shirt pocket.
Bosch N/A (AAA or USB-C depending on model) Platform
Standalone tools. The GLM 50-27 CG uses USB-C rechargeable. Older models use AAA batteries. Not part of any cordless tool platform.

Frequently Asked Questions
Can a laser measure replace a tape measure?
For room measurements, wall-to-wall distances, and ceiling height, yes. Faster and more accurate over long distances. For marking cut lines on lumber, no. You still need a tape for physical marking.
Do laser measures work outdoors?
The laser dot becomes invisible in bright sunlight past about 30 feet. The GLM 50-27 CG solves this with a camera viewfinder that shows the dot on screen. Budget models work outdoors only on overcast days or at shorter ranges.
