Connect your plotter or a WiFi gateway, and Manta shows your instruments live and records wind, depth and speed through the water on every trip.
Instrument data in log entries
Your boat already measures wind, depth and speed through the water. Manta reads those values over WiFi, so every log entry carries the real numbers instead of a guess.
What it adds
- Wind, depth and speed through the water, live on screen
- The real values recorded with every log entry
- Current, from speed over ground against speed through the water
- Wind and depth in your charts and replays
- The data your polar diagram is built from
- An alert on your phone when the data stops mid-trip
Which plotters work
B&G, Simrad and Lowrance share the same wireless system and stream to Manta directly. Garmin's Cortex M1 hub does too. Garmin GPSMAP and ECHOMAP, Raymarine and Furuno displays keep their WiFi for their own apps; for them, a small WiFi gateway on the NMEA 2000 network does the job. The full list is in Connect your plotter.
Plotters without WiFi
Almost every boat with instruments has an NMEA 2000 or NMEA 0183 network. A WiFi gateway plugs into it and puts the data on the air, while your plotter stays untouched. See WiFi gateways for proven models.
Connect
In Settings, open “Connect your plotter” under Instruments. Manta searches the WiFi for your plotter or gateway on its own; your iPhone and the plotter just need to be on the same network. If you bring the plotter into your phone's hotspot, enable “Maximize Compatibility” there, as most plotters only see 2.4 GHz networks.
Free and Pro
Connecting your instruments is free: Manta shows them live and records every value on every trip. The charts, the polar and the smart entries built from them are part of Manta Pro. Your first three trips with instruments, each longer than one nautical mile, keep their charts, performance data and automatic entries for good, and buying Pro later lights up the trips you already sailed.
Questions
Which plotters work directly?
B&G, Simrad and Lowrance displays with WiFi stream to Manta directly, and so does Garmin's Cortex M1 hub. Garmin GPSMAP and ECHOMAP, Raymarine and Furuno displays share their WiFi only with their own apps, so use a gateway.
Do I have to change my plotter setup?
No. A gateway just listens on the instrument network alongside your plotter, which stays untouched.
Which gateways work?
Any gateway that streams NMEA 0183, or NMEA 2000 in the Yacht Devices RAW format, over TCP or UDP. Proven ones include the Yacht Devices YDWG-02, Actisense W2K-1 and Digital Yacht NavLink2.
Is this part of Pro?
Connecting and recording your instruments is free, on every trip, and you see them live on screen. Manta Pro adds the charts, the polar and the smart entries built from them. Your first three trips with instruments, each longer than one nautical mile, keep their charts, performance data and automatic entries for good.
