On modern construction sites the batter board is increasingly being supplanted by a rotating laser. The laser is, in vertical operation, placed on a batter board holder fastened to the batter board by a clamping screw. The batter board holder is provided with a turntable allowing rough alignment of the rotating laser.
The laser receiver with the receiver holder is clamped on the opposite side of the batter board. Thanks to the AutoAlign function, the laser plane automatically aligns with the laser receiver in the case of the PRIMUS 2 HVA and PRIMUS 2 HVA2N models. Furthermore, the laser plane is automatically monitored and if necessary corrected by the AutoAlign function.
