Product Note: The HV101 laser transmitter is automatically self-leveled in the horizontal and vertical planes and sends a continuous 360° laser reference over the entire work area. The HV101 laser is easy to set up and use and is rugged enough for the toughest job site. Simple controls allow operators to carry out many functions with "one-touch" commands. A remote control offers scanning, speed control, slope settings, and alignment control for fast one person setups.
