T70412 – Magnum Radar 12kW with 4ft Antenna and 15m Cable

The Magnum 12kW (4ft) radar represents the pinnacle of Raymarine’s open-array radar lineup, combining an immensely powerful 12kW transmitter with a convenient 4-foot antenna array. This configuration yields an extraordinary maximum range of up to 96 nautical miles, extending your watch far beyond that of lower-powered radars. The leap to 12kW power is significant – it provides roughly three times the transmit power of a 4kW unit, which translates to the ability to detect extremely small, weak, or distant echoes that lesser radars might miss. Offshore anglers and long-range cruisers particularly value this model for its enhanced bird-finding capabilities and improved performance in heavy weather. Even with the standard 4ft antenna (versus a larger 6ft option), the 12kW Magnum excels at punching through rain clutter and atmospheric conditions, maintaining solid contacts on targets at the fringe of its range.

This radar’s high power output truly shines in challenging scenarios. For example, in dense fog or driving rain, the Magnum 12kW can continue to delineate shorelines and track vessels where other radars struggle. Its ability to spot small craft or obstacles at extreme distances provides an extra margin of safety for large yachts and commercial vessels venturing far offshore. All the sophisticated features of the Magnum series are on board: Bird Mode is even more effective with 12kW behind it, allowing you to detect seabird activity at greater ranges, which is a boon for finding fishing grounds. The fully automatic MARPA target tracking remains precise and stable, benefiting from the stronger return signals – you can trust it to monitor numerous contacts simultaneously, even those near the edge of the radar’s reach. The True Trails feature continues to overlay historical wakes behind moving targets, giving you clear insight into their movements over time. In essence, the higher power doesn’t complicate operation; it simply amplifies the radar’s effectiveness in all its functions.

The T70412 Magnum 12kW package comes complete with the 4-foot open array scanner, the 12kW pedestal (transmitter) plus the VCM100 power module, and a 15 m RayNet interconnect cable. Installation and integration are straightforward for any installer familiar with Raymarine systems. Despite its power, the unit interfaces via the same RayNet/SeaTalkHS network and is fully compatible with Raymarine’s Axiom and Axiom Pro displays (as well as other LightHouse 3 MFDs), and it can be adapted into older SeaTalkhs setups if upgrading an existing vessel’s electronics. For those who demand even finer resolution, the Magnum 12kW is also available with a 6-foot array (model T70414), which provides a narrower beam for pinpoint target definition. However, the 4-foot version already strikes a great balance, delivering the punch of 12kW in a form factor that fits many radar arches without issue.

Raymarine often notes that the 12kW Magnum is “the choice of competitive anglers and professional captains” – and for good reason. It gives commercial-grade performance to serious recreational boaters and workboat operators alike. Offshore sportfishing boats benefit from the radar’s ability to spot diving birds miles away, leading them to the fish, while megayacht captains and commercial ships appreciate the extended range for early warning of weather or traffic. In every use case, the Magnum 12kW (4ft) provides an invaluable overview of your surroundings, from the immediate vicinity to the far horizon, empowering you to navigate safely and make informed decisions out on the open ocean.
