CRAFTSMAN CMHT77638 Laser Distance Meter 65 ft

What it is and who it's for

The CRAFTSMAN CMHT77638 is a laser distance meter with a 65-foot measuring range designed for quick indoor layout tasks. It calculates distance, area and volume automatically from a simple two-button interface. A Class 2 laser operating between 620 and 690 nm provides accuracy within one-eighth inch at 30 feet. The IP54-rated plastic housing resists dust and splashes on job sites.

Thermals, noise and power in normal use

The device runs on an internal lithium-ion cell charged via the included USB cable, eliminating disposable batteries. With no moving parts it operates silently and generates negligible heat during typical measuring sessions. The lightweight 0.01-ounce body and compact 7.2 by 4.5 by 1.7 inch form factor stay cool in hand during repeated point-and-click use.

Behaviour under sustained load

Continuous measurement mode lets the user track a target in real time without pausing for single readings. The laser remains active while the button is held, delivering a steady stream of distance data for layout work. Battery life supports extended sessions, and the IP54 seal maintains protection during prolonged outdoor exposure to dust and light rain.
