The Leica RC800A Remote Control 840706 upgrades the Rugby 820 and 840 rotary lasers with semi-automatic dual-grade functionality. Just dial in your desired percentage grade to the X or Y axis, or both at the same time, and the Rugby will automatically match the grade. The Smart Slope function ensures maximum accuracy by keeping an eye on the amount of time elapsed and temperature changes throughout the day. With a range of up to 325' (100 m), the RC800A remote control is designed to boost productivity and add convenience to your job site.
The semi-automatic dual-grade enhancement is only available on the new Rugby 820 and 840 models (those purchased after November 12, 2015). Look for the label on the control panel saying “Leica RC800 REMOTE CAPABLE Dial-In Grade” to make sure that your Rugby rotary laser will work with this remote control.
