This 165 ft. green-beam laser measure is a fully featured tool with an easy-to-read color display， great accuracy， an inclinometer for tilt angle and reinforced housing for durability. The Bosch BLAZE GLM165-27CG uses Green-beam technology， which generates lines up to 4X brighter than standard red beams. The laser has accuracy up to plus minus 1/16 in.， plus it includes a rounding button for easily rounds results and haptic feedback for loud jobsites. The digital laser measure also offers Bluetooth functionality， so users can digitally transfer measurements to a smartphone or tablet through the free Measure On app. It is IP65 rated and has an ergonomic design for better grip. The Bosch GLM-BAT 3.7-Volt Lithium-ion Battery delivers greater runtime than standard AA batteries for select Bosch BLAZE Laser Measures. It provides about 60% more runtime than AA batteries at normal room temperature and the GLM-BAT is not as affected by cold temperatures as alkaline batteries. The battery features convenient USB charging. It can charge using various 5-VOLT power supplies， such as power adapters， PCs， laptops or portable power banks， for maximum flexibility.
