Garmin 010-01248-10 GMI Wired Start Pack 52

The bundle includes a gWind masthead transducer, a GMI 20 4" bright colour display, a GND 10 Black Box Bridge along with a 52 mm (2") diameter DST800 thru-hull Smart transducer.

  • Three-bladed propeller for more accurate True Wind Speed (TWS) in lighter air; twin-fin design gives a more stable True Wind Angle (TWA)
  • The optic reading technique for superior performance at low wind speeds with excellent linearity
  • GND™ 10 Black Box Bridge's NMEA 2000® data to Nexus Network and enables Garmin compatible chartplotters to integrate with Nexus sail equipment and vice versa
  • Easy plug-and-play installation between Nexus, Garmin chartplotters, NMEA 2000 and USB
  • The gWind transducer, featuring twin-fin technology and designed for more accurate TWS and TWA
The gWind transducer features twin-fin technology with a 3-bladed propeller for more TWS in lighter air, while the twin-fin design gives a more stable TWA. The 3-bladed propeller, unlike a cup's design, is always efficient.

Combined with optic reading, this transducer provides superior accuracy at low wind speeds and provides excellent linearity. The transducer is connected directly to the GND 10, which sends the wind information to the GMI 20 and/or GNX 20.

The GND 10 allows the gWind Transducer data to be shared between the NMEA 2000 network and a Nexus Network. It is a simple plug-and-play installation with no user setup or system configuration required.

The GMITM 20 shows the wind information and depth, speed and 100+ marine and vessel parameters.

Its large, bright 4" colour display with extra-large digits is easy to read at a distance and 170° viewing angle. A glass-bonded finish lens on the GMI 20 prevents fogging and increases contrast.

Daylight readability is enhanced with a high contrast colour scheme. For enhanced night visibility, you have a choice of red/black, green/black or the normal night mode colour 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. The NMEA 2000® network supplies power.

The GMI 20 also features a dedicated race timer that counts down and counts up, with an internal beeper.

The DST 800 thru-hull smart transducer provides water depth, water speed, and water temperature data to the NMEA 2000 network.

This 100 W transducer can read depths up to 330', has an operating frequency of 235 kHz, and a 10 x 44 degrees beamwidth.
