Discoverer features a large 19/22-inch screen that can be used as an extension screen for Garmin's fishing series.

Professional LCD Waterproof Touchscreen Marine Monitor

The LCD waterproof touchscreen marine monitor from discoverer  is designed specifically as a high-brightness HDMI external display for marine electronics, with a strong focus on Garmin sonar and fishfinder systems. Built for harsh offshore environments, it delivers stable performance under intense sunlight, heavy rain, vibration, and saltwater exposure.

Featuring an industrial-grade full-view LCD panel with a native resolution of 1920 × 1080 (Full HD) and brightness up to 1500 nits, this marine monitor remains clearly visible even under direct sunlight. Endless dimming from 0–1500 nits allows precise brightness control for day and night navigation.

Optimized Touch Experience for Marine Operation

The display is equipped with a 10-point capacitive touchscreen powered by a high-performance touch controller. Using optical bonding technology and outdoor-grade full lamination water glue, the screen achieves excellent light transmission, fast response, and reliable touch accuracy.

Even in pouring rain or wet operating conditions, the touchscreen remains responsive and controllable—making it suitable for real-world marine navigation and sonar monitoring scenarios. The anti-glare and UV-coated glass further reduces reflections while improving outdoor visibility.
