Imagine slicing through choppy waters with confidence, knowing exactly how the wind is shifting and what lies beneath your hull. The Garmin GMI Wired Start Pack 52 delivers that edge, bundling essential marine sensors and a versatile display into one robust package. Tailored for boaters who demand reliable data without the hassle of piecemeal setups, this pack transforms your vessel's cockpit into a command center.
Cruising sailors appreciate its wind accuracy during tacks, while powerboaters rely on speed and depth readings for safe navigation in unfamiliar bays. By leveraging a plug-and-play NMEA 2000 backbone, it scales effortlessly—add more displays or sensors as your adventures grow.
At the heart of this pack sits the GMI 20, a 4-inch powerhouse engineered for the harshest marine environments. Its glass-bonded lens shrugs off fog and glare, ensuring crystal-clear views from dawn patrols to midnight watches. Extra-large digits and a 170-degree viewing angle mean glances from the helm stay sharp, no matter the angle.
Customize screens to auto-cycle through wind angles, boat speed, depth, or fuel flow—over 100 parameters await. Night modes toggle between subtle red, green, or standard palettes, with dimmer control for stealthy anchoring. Profiles snap-switch for sail racing, fishing trips, or motoring, all powered seamlessly via NMEA 2000. No fumbling with wires; just vital info at your fingertips.
Wind data isn't just numbers—it's your guide to perfect sails and tactical edges. The gWind transducer's three-bladed propeller spins efficiently even in whispers of breeze, delivering precise True Wind Speed and Angle via optical sensing. Twin fins stabilize readings, banishing the inconsistencies of cup-style anemometers.
Mounted topside, its 25-meter mast cable reaches helms with ease, feeding data network-wide. Boaters report fewer gust-induced errors during light-air regattas, making it a favorite for competitive skippers honing their upwind legs.
Thru-hull mounted for direct water contact, the DST810 packs depth to 330 feet, speedy 5 Hz water speed, temperature, and attitude sensing into one unit. Track heel and trim for sail trim or pitch/roll for stability in rough seas—data flows straight to your NMEA network.
Bluetooth pairing with the CAST app simplifies calibration, tweaking for hull speed or multiple heel angles right from your phone. Operating at 235 kHz with a wide 10x44-degree beam, it excels in shallow drafts or weedy waters, helping avoid groundings that sideline weekend warriors.
NMEA 2000 is the secret sauce here—a single backbone connects everything, from chartplotters to additional instruments. The included GND 10 bridge and T-connectors make daisy-chaining a breeze, powering up without a dedicated supply in many setups.
Start small, then grow: link to Garmin radars, autopilots, or engine monitors. Real-world installs show it thriving on everything from 25-foot day sailors to 50-foot cruisers, minimizing wiring clutter for cleaner cockpits.
This all-in-one kit cuts setup time, letting you focus on the water rather than the workbench.
Powerboaters gain instant situational awareness—depth alarms buzz before shallows, speed logs log wake sports accurately. Sailors trim sails smarter with stable TWA/TWS, attitude data fine-tuning weight distribution.
Durability shines: IPX7 waterproofing, corrosion-resistant materials withstand salt spray year-round. Maintenance is minimal—rinse transducers post-use, inspect cables annually. Many owners rave about its role in personal bests, from coastal hops to offshore passages.
Mount the GMI 20 flush or bracketed for optimal sightlines. Run the gWind cable inside mast conduits to dodge chafe. DST810 thru-hull needs fairing blocks for clean water flow—pair with anti-fouling paint for longevity. Test the network post-install: drop a terminator at each end, power up, and watch data sync across screens.
Pro tip: Calibrate DST810 in calm conditions via Bluetooth for spot-on speed-over-ground matches with GPS.
It's ideal for both powerboats and sailboats, from day sailors to larger cruisers needing wind, depth, speed, and attitude data.
The three-bladed propeller and optical sensing provide superior True Wind Speed accuracy even in light air, outperforming traditional cup anemometers.
Yes, Bluetooth connectivity allows direct calibration through the AIRMAR CAST app, including multi-angle speed adjustments.
Absolutely—NMEA 2000 compatibility ensures seamless connection to Garmin chartplotters, autopilots, and more instruments.
It draws power directly from the NMEA 2000 network, simplifying wiring.
It reliably reads depths up to 330 feet with a high-frequency beam for clear bottom returns.
Yes, the anti-glare glass-bonded lens and high-contrast colors ensure excellent daylight visibility from wide angles.
GMI Wired Start Pack 52
A Perfect Start to Your New Instrument Network On Board
A Good Start or Complete Pack
With a GMI Wired Start Pack 52, you'll have all the equipment you need to know what's going on with the wind and the water. If you're looking to install more than just one instrument in your network, this is the perfect start pack to use. By using the NMEA 2000 network, it's easy to expand with the number of instruments you want.
GMI 20 Marine Instrument
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-plus 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 on 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 you having to do a thing. This is especially advantageous for 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.
gWind Transducer
gWind transducer features twin-fin technology with 3-bladed propeller for more accurate True Wind Speed (TWS) in lighter air while the twin-fin design gives a more stable True Wind Angle (TWA). The 3-bladed propeller, unlike a cups design, is always efficient. Combined with optic reading, this transducer provides superior accuracy at low wind speeds and also provides for excellent linearity.
AIRMAR DST810 Thru-hull Smart Transducer
DST810 combines precise depth, speed and temperature data with attitude sensing for heel/trim and pitch/roll inputs which it provides to the NMEA 2000 network and GNX 20 instrument. This multisensor transducer can read depths to 330', offers fast 5 Hz water speed signal output and has an operating frequency of 235 kHz with a fan-shaped beamwidth of 10 x 44 degrees. Additionally, wireless connectivity to devices with BLUETOOTH technology enables DST810 calibration directly through the CAST app from AIRMAR. Advanced speed calibration allows for calibration at multiple heel angles and speeds.
