SST-110 Sea Temp GaugeThe right tool at the right price for all saltwater anglers, both inshore and affordable, waterproof, analog sea surface temp instrument with LARGE digital numbers that can literally be seen from 15 to 20 feet away. With its large four-digit LCD display (measuring 4.3 inchesx 4.3 inches x 3.5 inches), rugged water-resistant construction and advanced features, Si-Tex's SST-110 is ideal for a wide range of recreational and commercial fishing vessels. It can be easily installed on the flybridge of a large sportfisherman or on the instrument panel of a 17-foot open center console. It has the ability to view water temperature at a glance (in Fahrenheit/Celsius resolution), find favorable temperature zones and pinpoint critical off-shore temp breaks. For maximum accuracy and to compensate for slight differences in transducers, the displayed temperature can be easily calibrated by the operator using the SST-110's front panel keys. Boaters can also set high and low temperature alarms for audible alerts to temperature fl uctuations or hard temperature edges. A temperature trend arrow on the display tells the user at a glance if sea temperatures are getting warmer, cooler or remaining operation in any onboard environment or ambient light conditions, the SST-110 offers five levels of backlighting that can be selected and remotely switched On/Off . All set up and calibration constants are saved to a nonvolatile memory, retaining settings for the next time the unit is powered up. For easy integration on most professional fishing vessels, the SST-110 outputs standard NMEA 0183 water temperature data and works on both 12 and 24 VDC systems. Even with its large digital display, the SST-110 draws only amps ( amps with full backlighting).Features: Degree ResolutionEasy CalibrationTemperature AlarmsTrend Indicators
