I use two on our boat, a Simrad NSS9 on the upper helm and a NSS12 on the lower. Both are multi-function and networked so you can add components to your budget.
Radar, cameras, depth sounders, engine instruments, autopilots, etc., basically anything that can be added to a NMEA 2000 data bus can be managed with these types of displays.
I prefer these to Garmin units having used both on charters. I think the Simrads are simpler and more intuitive. Not sure on pricing or anything like that, and I do know I am a full generation behind the latest versions.
These units have internal databases and updates are available from the Simrad website at no charge, but the databases are not completely updated with full NOAA charts. I have a separate program running on a windows PC, Coastal Explorer. Coastal Explorer is a subscription and is updated constantly via the internet each time it boots up and is a legal chart system. It is not free...
So I use the Simrad units to interface with the boats various components while underway - foremost the autopilot, but use the PC and coastal explorer for trip planning, legal charts as well as the other functionality that CE built into their program. Also while underway.
The combination of functionality in these two units far surpasses anything available in aviation, at any level.
Try Fisheries Supply in Seattle for better prices than West Marine, otherwise hit the internet. Matt in Tacoma.
