My only thought on running any helm mounted electronics is to avoid external wiring at all costs. When someone loses their balance walking around the helm in a seaway or even at anchor, they will grab the first available "thing" to keep from falling. If the "thing" is a loose wire or is attached to a wire, it is easy to dislodge the tiny internal wires from their connectors, rendering the instrument inoperable. And those connectors will have a better chance of remaining corrosion free if they're enclosed in a housing. Half Magic's new ES 75 is going in a pod on an enclosed arm attached to the pedestal guard. NMEA 2000 backbone being run bow to stern for future additional instruments, radar, AIS and autopilot.
