At press time in early January, Raymarine was set to release its 3.3 version of LightHouse software for Axiom and Axiom Pro units, as well as prior-generation eS-Series and gS-Series products. The upgrade enhances speed and performance, and allows Axiom to network with eS and gS. LightHouse 3.3 adds historical sensitivity adjustments and an optional legend to RealVision 3D sonar, and brings in SiriusXM weather and Navionics Plotter Sync. When linked to the Navionics Boating app on a smartphone or tablet, 3.3 allows synchronization of waypoints, routes and tracks on the multifunction display. The software update is free for applicable units.
