The PR 300-HV2S dual-slope rotating laser from Hilti offers horizontal, vertical and dual-slope mode with a user-guided interface. The unit includes a remote and receiver in one device. A rubber housing prevents damage to the rotating laser at drops up to 5 feet from a tripod, while the receiver can withstand drops up to 6.5 feet. The rotating laser includes an auto-alignment feature that aligns the laser to the receiver, allowing the user to read the slope value. In vertical mode, auto-alignment replaces string line applications. 800/879-8000; www.us.hilti.com.
