Garmin data sheets are full of acronyms. These are the ones that really matter on a RIB, put the way we put them on the phone.
- Traditional CHIRP
- The classic sounder, with high detail on targets: it tells you what is under the keel and how deep.
- ClearVü
- High-definition scanning beneath the boat: seabed and structure appear almost like a photograph.
- SideVü
- The same scanning, but to the sides: for approaching shoals, jetties and rock walls.
- UHD2
- The ultra-high-definition generation of ClearVü and SideVü, with contrasting colours to tell fish from structure.
- Panoptix and LiveScope
- Live sonar: it shows in real time what is moving around the boat, with its own transducer.
- Garmin Navionics+ and Vision+
- The nautical charts: daily updates and Auto Guidance+, which plots a route respecting draught and clearance; Vision+ adds shaded relief and satellite imagery.
- Quickdraw Contours
- As you go, the plotter draws the map of the seabed where you are, and can share it with the Quickdraw community.
- ActiveCaptain
- The free app that links your phone to the plotter: updates, notifications, chart management with OneChart and Quickdraw data.
- NMEA 2000 and NMEA 0183
- The standard by which chartplotter, VHF, AIS, autopilot, engine sensors and Fusion audio talk to each other over one network cable.
- J1939
- The port that reads engine data, revs, fuel flow and alarms, and shows them on the plotter screen.
- Garmin Marine Network
- When there is more than one Garmin device on board, they share maps, user data, radar and camera images.
- inReach
- Satellite messages typed on the plotter's keyboard, beyond mobile-phone coverage, with a separate inReach device.
