Perfectly Designed for Power and Sail Vessels

  • Marine instrument display clearly shows depth, speed, wind and 100+ marine and vessel parameters
  • Large, bright 4” color glass-bonded lens display with anti-glare finish
  • Easy to read from a distance and 170 degree viewing angle
  • Enhanced night time readability with backlight dimmer and full color or new red/black or green/black color schemes
  • Enhanced daylight readability with new high contrast color option

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.

Set Sail with Ease

A glass-bonded finish lens on the GMI 20 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® 500/700 series, GPSMAP 8000 Glass Helm series or legacy Garmin chartplotters.

Two Options

When selecting your GMI, there are 2 bundled versions to pick from: one includes a GWS™ 10 wind transducer and the other, a DST800 thru-hull smart transducer and GWS 10 transducer. The wind transducer records speed and direction, air temperature and barometric pressure. The thru-hull records water depth, water temperature and boat speed.

In the box:

  • GMI™ 20*
  • Black trim piece snap cover
  • Silver/black trim piece snap cover
  • Protective cover
  • Flush mount gasket and hardware
  • NMEA 2000® T-connector
  • NMEA 2000 drop cable
  • Documentation

*GWS™ 10 and/or DST800 thru-hull smart transducer are included with some models. These boxes also include NMEA 2000 backbone cables on spools, NMEA 2000 field installable connectors, NMEA 2000 in-line terminators and in-line lightning arrestors.
