• Theft protection: an alarm is triggered if the GRL 500 H/HV is moved without the LR 50 Professional during operation.
• Calibration reminder: automatically indicates calibration requirement.
• Slope function: enter slope values directly and precisely using the LR 50 Professional keypad.
• Sleep mode: When the tool goes into sleep mode, all settings are saved and the theft protection and the Anti-Drift System remain operational.
• Centre Line button: automatically aligns the laser beam with the centre of the receiver and measures the slope value.

• Simultaneous charging: the Li-Ion batteries in both components are charged together in very little time.
• Line Control: align the vertical line as desired in vertical mode using the arrow buttons.
• Anti-Drift System: prevents levelling errors in the event of shocks or vibrations.
• Relative height display: distance between where the laser beam hits the reception area and the centre of the receiver.
