The CST/berger ALH is a rugged, automatic self leveling laser level designed for civil & commercial contractors, builders and concrete placers.

Built to withstand the toughest job site conditions, the ALH is waterproof, with an IP weatherproof rating of IP67.
Very easy to operate, simply mount the laser onto a heavy duty tripod, press power, and the ALH automatically levels by itself using the electronic servo-driven leveling system.
If the laser is bumped or knocked during use, the Anti-Drift height alert system automatically turns off the laser and warns the operator.

The ALH also features a manual grade slope matching feature, with up and down arrows. This slope matching grade feature allows the user to align the laser for basic single grade slope and drainage work.
Whilst in manual slope mode, the ALH has the added advantage of "Cross Axis Self-leveling", which keeps the cross axis level at all times.

With a long operating range of 850 metres, the ALH can be used on even the largest civil contracting sites.

Made in the USA, the 3 Year warranty covers any defects in materials or workmanship.
