FLIR Thermal Camera Compatibility

Extend your marine capabilities with the FLIR thermal camera compatibility of the Garmin GPSMAP 79S. When paired with an optional FLIR thermal camera, the device can display thermal imagery directly on the screen, enhancing visibility in darkness, fog, or other low-visibility conditions. This integration is particularly valuable for night navigation, man-overboard situations, wildlife spotting, or security applications. The Garmin GPSMAP 79S becomes a powerful thermal imaging system when connected to FLIR cameras, providing capabilities typically found in much more expensive marine systems.

Wireless Connectivity and Data Sharing

Expand your marine electronics ecosystem with the comprehensive wireless capabilities of the Garmin GPSMAP 79S. The device features ANT+ technology for connecting to compatible sensors including temperature probes, heart rate monitors, and speed/cadence sensors. Bluetooth connectivity enables wireless data transfer to compatible devices and connection to the Garmin Connect mobile app. The Garmin GPSMAP 79S can share waypoints, routes, and tracks with other compatible Garmin devices, creating an integrated navigation network among multiple units on the same vessel.

Rugged Marine Construction and Display

Withstand harsh marine environments with the durable design of the Garmin GPSMAP 79S. The device features an IPX7 waterproof rating, meaning it can withstand immersion in 1 meter of water for up to 30 minutes, making it suitable for the wettest marine conditions. The bright, sunlight-readable 2.6-inch display remains visible in direct sunlight, while the rugged housing protects against impacts and the corrosive marine environment. The Garmin GPSMAP 79S floats in water, an essential safety feature that prevents loss if accidentally dropped overboard according to marine equipment standards.

Battery Performance and Power Options

Maintain navigation capability throughout extended marine excursions with the flexible power system of the Garmin GPSMAP 79S. The device operates on 2 AA batteries, providing up to 20 hours of typical use, or can be powered by an optional rechargeable battery pack for convenient recharging. The power-saving features include adjustable backlight settings and automatic power-off options to extend battery life during long trips. The Garmin GPSMAP 79S also supports external power connections for continuous use when mounted on a vessel with available power sources.
