GNX™ 010-01248-90 Wired and DST810 transducers


GMI 20 Wired Sailing Starter Pack

A complete instrument package at an attractive price

The GMI 20 digital marine instrument display is perfectly designed for both power and sail vessels. Designed to clearly show depth, speed, wind and 100+ marine and vessel parameters, its large, bright 4" color display with extra-large digits is easy to read at a distance and 170 degree viewing angle.

A glass-bonded finish lens prevents fogging and increases contrast. Daylight readability is enhanced with a high contrast color scheme. For enhanced night visibility, you have a choice of red/black, green/black or the normal night mode color scheme along with a dimmer control. Screens can be set to auto-scroll, cycling between pages automatically without your having to do a thing. This is especially advantageous to sailors as it allows you to install the unit(s) in a greater variety of locations on the vessel. Default profiles can be customized for powerboat, sailboat, fishing, engine/fuel, plus several other user-specified profiles. Power is supplied by the NMEA 2000 network.

In addition, the GMI 20 also features a dedicated race timer that counts down and counts up, with an internal beeper. Included are 2 trim snap piece cover options which allow you to match the GMI 20 with the new GPSMAP series or legacy Garmin chartplotters.

The package features the gWind masthead unit. The twin fin design gives a more stable wind direction reading, while the forward-facing propeller is superior in low wind conditions.

DST810 provides water depth, water speed and water temperature data to the NMEA 2000 network. This 100 W transducer can read depths up to 330 feet, has 5Hz speed updates, and can be calibrated from your smartphone.
