Dual-head laser meter for site layout

The Emerson BLM-210GT measures bidirectionally to 656 feet and unidirectionally to 328 feet with ±1/16 inch accuracy. A green Class 2 laser and ±90° electronic angle sensor support construction, surveying and renovation tasks. The IP54-rated housing resists dust and water on active job sites.

USB-C charging and tripod mount simplify power

A 3.7 V 850 mAh lithium-ion cell reaches full charge in 1.5 hours and runs up to 5 hours continuously. The built-in 1/4"-20 thread attaches directly to standard tripods, freeing both hands for layout work. Backlit LCD readouts remain visible in bright or low light.

Nine modes and 100-record memory sustain all-day

Length, area, volume, angle, wall area and four Pythagorean functions cover diverse calculations without switching tools. Unit switching between metres, inches, feet and feet-plus-inches avoids manual conversion. Automatic shutdown after 180 seconds preserves charge during breaks between measurements.

Questions about this item

How long does the 850mAh Li-ion battery last under continuous daily use?

The 3.7V 850mAh rechargeable Li-ion battery provides up to 5 hours of continuous use and fully charges in 1.5 hours via USB-C.

What heat or noise should I expect when the meter runs all day on site?

The device has no fan and uses a Class 2 green laser under 1mW, so it runs silently with negligible heat during extended operation.

What mounting option do I already need on my tripod for the 1/4"-20 thread?

A standard 1/4"-20 tripod mount is required; the meter includes a magnetic back for metal surfaces as an alternative.
