The SI-TEX SST-110 delivers large-format digital sea temperature readings legible from 15–20 feet away, making it a practical choice for everything from a 17-foot center console to a flybridge sportfisher. Its waterproof, rugged housing pairs with NMEA 0183 output and dual-voltage compatibility to fit cleanly into most existing vessel electronics setups. Operator-adjustable calibration, high/low temperature alarms, a trend arrow, and five backlight levels round out a feature set suited to both inshore and offshore fishing use.
