laser sets up fast, it's totally automatic in both horizontal and
vertical modes. There are no leveling screws or vials to rough level.
Just mount it on a tripod, turn it on and it's ready to go! If the
GA2120 is disturbed, the H.I.
Alert shuts off the laser, preventing inaccurate readings if the
H.I. (height of instrument) has changed. In addition to leveling,
the GA2120HV can be used for
short-range vertical and constant squaring for 90° angles. Ideal
for contractors who work primarily in horizontal, but have occasional
use for vertical alignment at short distances. Motorized leveling
range, allowing quick Rugged design includes sturdy aluminum head
protection , and an electronic leveling system that's more durable
than delicate wire-hung compensators.The laser is weatherproof for
a wide range of outdoor applications.
