There is an intermittent problem with the auto-leveler on this unit. When turned on, it usually gets stuck in a constant state of self-leveling. Sometimes it settles into level and starts to rotate normally, but most of the time it ends flashing an error and you need to start over again. We cannot rely on it as a company and HILTI no longer offers service for this unit. 

Also included are the fully functional PRA 35 Remote Control/Laser Receiver, the PRA 80 Laser receiver holder, a li-ion battery, and a charger.
