The Spectra Precision Laser (HV301G) is an automatic self-leveling laser that offers superior green-beam visibility for horizontal, vertical, and plumb applications, says the maker. Intuitive controls and a 360-degree remote control allow for simple one-touch commands. A height-of-instrument alert turns the beam off when the laser elevation changes or is disturbed. Accuracy is 332 inch at 100 feet, with an interior operating radius of up to 250 feet. Price: $1,395. 937-482-0200. trimble.com
