GAT220 : Automatic self-leveling in horizontal

One-Touch electronic leveling speeds setup. The GAT220 is totally automatic: just mount it on a tripod, turn it on, and it's ready to go! This solo leveling system allows one person to easily set up the laser and take rod readings with the included detector.
Rugged and reliable, the laser is ideal for setting forms and footings, screeding concrete, checking elevations, and other general construction leveling tasks.
H.I. warning shuts the laser off automatically if it's disturbed, preventing inaccurate readings.
Other features include: long battery life (runs an entire month on two D alkaline batteries), recharge capabilities, electronic field calibration that saves trips to the repair shop, and accessible head and visible beam that lets you work indoors setting 4' (1m) marks.
Set manual grade to ± 5 ° with the push of a button! You can match slope in both X and Y axes using the laser's manual mode to override self-leveling.
