The Stabila REC 150 Receiver For Rotary Lasers has two displays: one each on the front and back for fast measuring and taking readings in any position. Two sensitivity levels simplify setting-up over longer or shorter distances. It has a IP67 rated design, meaning that it is water and dust proof. The receiver has acoustic guidance with selectable volume and a series of symbols, that will indicate your distance from the reference height and whether you are too high or low. Its loud signal can be heard even with a loud background noise, and its marked edge allows exact marking of the reference height. Supplied with a bracket to fix onto a levelling rod.
