6.2. Mode Switching
Press the Mode button to cycle through the available measurement modes:
- Standard Mode: Basic distance measurement.
- Continuous Measurement Mode: Press and hold the Power/Measurement button to continuously scan and display distances to multiple targets. Useful for quickly identifying distances to hazards or multiple points.
- Pin Lock Mode: In this mode, the device prioritizes the closest target, such as a flagstick, ignoring background objects. When the target is locked, the device vibrates (Jolt function) and displays the distance.
- Slope Compensation Mode: Calculates the adjusted distance to play, taking into account elevation changes (uphill/downhill). The LED indicator will be off when this mode is active.
- 3-Point Distance Measurement Mode: Measures the distance between three points, useful for planning shots from a golf cart or around obstacles.
- Horizontal/Vertical Measurement Mode: Measures horizontal distance and vertical height to a target.
- Speed Measurement Mode: Measures the speed of a moving object.
