Maintenance Tips

• Keep lens crystal clear: Use a microfiber cloth and lens-safe cleaner—clean optics are essential for accurate ranging and clear target lock.
• Protect image stabilization system: Avoid excessive shaking or impacts; stabilization helps eliminate hand movement for precise readings.
• Maintain battery health (CR123A): Replace as needed and remove during long-term storage to prevent leakage and ensure reliable performance.
• Keep sensors & display clean: Ensure the laser emitter and red illuminated display remain free of dust for accurate distance readings.
• Check magnet & exterior grip: Clean contact surfaces to ensure secure attachment to golf carts and maintain firm handling.
• Dry after wet rounds: Waterproof design handles rain, but wiping down after use preserves electronics and lens coatings.
• Store in protective case: Use the included case to prevent scratches, impacts, and environmental damage.
• Avoid hard impacts: Magnesium chassis is durable, but drops can affect internal laser alignment and accuracy.
• Test ranging before play: Confirm PinSpotter and slope mode are functioning correctly for consistent on-course performance.
