GPO Flagmaster Slope/Pin Golf Laser Rangefinder GLRF 1800

The GPO Flagmaster 1800 is a premium golf laser rangefinder designed to help you assess distances on the course with high precision and confidence. With 6× magnification and a compact 20 mm objective lens, it offers optical clarity and a close-to-hand feel ideal for on-course use. The device can measure distances out to roughly 1,800 yards under optimal conditions, and it displays the results quickly—either as a straight line-of-sight distance or an angle-adjusted “slope” distance to account for elevation changes. Highlight features include a PinFinder (or flag-lock) mode that provides vibration and a visual indicator when you lock onto the flag, and a quick-scan mode that gives up to three readings per second. The slope mode can be turned off to comply with tournament rules, and when enabled it signals via red LEDs that angle adjustment is active. Built with a weather-resistant housing, a fast-focus ocular for quick aiming, and a one-hand ergonomic layout, the Flagmaster 1800 is tailored for golfers who want both versatility and performance in a compact package.
