Lighthouse 3 is Raymarine’s keystone interface that takes full advantage of its quad-core processors (think Intel Quad Core processors in personal computers, though Raymarine won’t reveal the maker or speeds of its product). This allows the Axiom and Axiom Pro systems to multitask, with, among other things, up to four functioning display windows. The Lighthouse 3.4 update adds app functionality for a GRIB Weather app, a Bluetooth audio out, and Netflix and Spotify apps for onboard entertainment. Coming soon are apps for LED lighting, Seakeeper stabilizers and other cool systems. Progressively, fishermen are expecting their multifunction displays to offer total connectivity to every system on their boat.
