I first saw a digital rangefinder in the hands of the appraiser who was measuring the square footage of my third house. It was a cool tool, but I didn’t think the casual use I would put it to would justify the couple hundred dollars they cost at the time. Jump forward a few years — walking through the local hardware store I saw this Bosch rangefinder priced around $130, well within “almost reasonable” range.
Bosch’s Laser Distance Measure — I like “rangefinder” better — can measure from 2″ to 100′ with accuracy to 1/16″. It’ll also measure in metric units, and it’ll measure distances as you walk them off. The 4″-tall unit fits in your pocket. Four AAA batteries will last for about 30,000 measurements, and it’ll do all the regular length, square footage, and volume measurements.
Now to find a project that requires an accurate electronic measuring tool.
