M-121

The M121 integrates GPS, radar, sonar, fuel management and video functionality into a daylight viewable high-resolution display. The M121 excels as a complete navigation package for boats of all sizes. Northstar High Definition Digital radar combined with C-Map cartography provides a comprehensive array of navigational aids, including chart overlay.

Radar
Northstar High Definition Digital Radar brings advanced signal processing, better target presentation and better clutter rejection with your optional Northstar Digital Radar system.

Sonar
Equipped with a powerful 1kW (RMS) sounder that automatically adjusts the output power (1kW or 600W) to match the wattage of your transducer. No separate sounder processor is required. Simply plug the transducer of your choice into the M121 and you're up and running.

A.I.S.
Optional Automatic Identification System receivers display vital vessel information from registered vessels on the chartplotter screen.

Fuel Management
On-demand access to your engine's gasoline performance data, as well as SmartCraft™ management for SmartCraft-enabled Mercury, Mariner or MerCruiser engines (optional fuel kit/SmartCraft™ gateway required).

Video (PAL/NTSC)
Northstar brings video to your helm. Connect a camera for deck monitoring, engine room surveillance, even underwater views. Or connect a DVD player or camcorder for entertainment at your helm (a separate audio output system is required for sound).
