Measurement Modes
The rangefinder offers multiple measurement modes for various applications. Press the "M" button (mode button) repeatedly to cycle through the modes.
- Standard Measurement: Measures direct line-of-sight distance to the target.
- Flag Locking with Vibration: This mode is designed for golf. Aim at the flagpole, and the device will lock onto it, ignoring background objects. The rangefinder will vibrate twice when the flag is successfully locked. Long press the power button for quick locking.
- Slope Compensation: When enabled, this mode calculates the actual playing distance by adjusting for elevation changes (uphill or downhill). This provides a more accurate distance for club selection. The slope function can be toggled on or off via a dedicated switch.
- Continuous Scanning: Allows for continuous measurement as you pan across multiple targets.
- Speed Measurement: Measures the speed of a moving object.
