Explorer Series Advantages

The GX1800G Explorer Series combines proven Standard Horizon reliability with innovative features in an ultra-compact package. The built-in 66-channel GPS eliminates external wiring complexity while the unique compass screen provides intuitive navigation to waypoints. The ultra-slim 3.3" rear case depth allows installation in spaces where standard radios simply won't fit, making the Explorer ideal for center console boats and space-constrained installations. Despite the compact size, Standard Horizon engineers included a large 2.6" x 1.4" display that's significantly bigger than typical compact radios, ensuring excellent readability. The selectable night mode display inverts colors to preserve night vision during nighttime operations—a thoughtful feature for serious boaters. Second station capability via optional RAM4 provides multi-station flexibility typically found only on larger, more expensive radios.

GPS Compass and Waypoint Navigation

The GX1800G's GPS compass screen represents a significant advancement in VHF radio interface design. Unlike radios that simply display numeric GPS coordinates, the circular compass screen provides intuitive graphical navigation. Store waypoints for your favorite fishing spots, marina entrances, or anchorages, then navigate to them using the compass display showing distance, bearing, and a graphical direction indicator. The large compass makes it easy to understand your positional relationship to your destination at a glance.
