Slope Compensation Switch
The SILLAID Golf Range Finder features an external slide switch to enable or disable slope compensation. This is crucial for tournament play where slope-adjusted distances are often prohibited.
- Slope ON (Red Indicator): Slide the switch to enable slope compensation. The device will calculate and display the "play as" distance, accounting for uphill or downhill terrain.
- Slope OFF (Green Indicator): Slide the switch to disable slope compensation. The device will only display the straight-line distance, making it compliant with tournament rules.
