Laser Level & Measuring Tape
A laser level for pinpoint scale, an 8' measuring tape for...8' of spatial knowledge, and a 58% discount for justification for buying it. The Handy Laser Level & Measuring Tape goes with a "3-pronged approach" that combines its fine-tuned tape measure with a triple-positioned leveling bubble, and a laser level. The measuring tape has both metric and imperial markings, with increments of 1mm and 1/32" respectively.
The laser portion of the tool requires 3 x AG 13 button-cells to operate; they're included with the purchase. The package also includes a beam adjustment tool and Phillips screwdriver.
