A real navigation instrument.In the phone already in your hand.
GPS, compass, AIS, tides — the full instrument, built to last the whole passage. For sailors, not tourists.
It's still alive when you reach for it.
A phone chart app that drains your battery by lunch isn't a navigation instrument — it's a liability. Magna Marine is built the way proper marine gear is built: it sips power, it goes quiet in your pocket, and it holds a charge across the whole passage. So when the light fails and you actually need it, it's there.
Real GPS position, real heading, real traffic. On the device you already trust to be in your hand.
It sips power on purpose.
Screen off, and the whole instrument goes silent — GPS, compass, and AIS all stop the instant your phone is in your pocket. Nothing runs behind your back. That single discipline is why the battery is still there at dusk.
Just the chart. No GPS, no compass, no AIS. For reading the coast at anchor. About 3% an hour.
GPS every five seconds, compass only when you're slow, AIS bounded to what's around you. About 7% an hour — a full day underway.
Per-second GPS, full-rate compass, complete AIS history. You spend the battery on purpose, when it counts.
You decide the draw. The instrument never decides for you.
Not a map with a dot. The whole instrument.
Real GPS fix, course and speed over ground.
Heading-up and course-up, tuned for swell wobble.
The vessels around you, live off the water.
The state of the water where you're standing.
The line to where you're going, laid on the chart.
Screen stays lit only while you're navigating.
Take the chart out. Keep the whole bridge.
Magna Marine lives inside Magna Earth — $14/mo or $129/yr.
