The compact, 7" high-definition, 480v x 854H pixels, TFT display is readable even in bright sunlight, and a freeze-frame function lets you stop the display for closer examination of fish, bottom detail, and more. The fully adjustable split-screen bottom zoom or bottom lock zoom separates fish from bottom and structure. Dual microprocessor allows high-performance operation, while the Rapid Response water temperature and graph quickly shows changes in water temperature. And an audible water temperature alarm sounds as your boat crosses the temperature zone. All have speed and water temperature sensors and transom-mount transducer.
