I have the raymarine
A50 with the preloaded "silver" world charts, minus east coast
It has been brilliant, it also came with a free hand held vhf radio
I have had it fitted to 2 boats and interfaced with the autopilot
, worked great!
Now on a 31' cruising sloop
, interfaced with a wheel autopilot
and wind/speed/depth and course controller, all wired myself via seatalk
, it has some limitations in that it only sends seatalk
and does not display the seatalk info, desipite receiving it, maybe if I used the seatalk NG connection it would be better.
Has performed great for 3 months of cruising in Malaysia
, spot on for accuracy and good depth
, shows all the lights and rocks, invaluable, in the right places, I have navigated in the night a lot with it. Easy to read in the sun or at night.
Just plot a route
as a series of waypoints and the autopilot x5 follows them, showing distance to waypoint, bearing etc, very useful, and you can display AIS
data as well, better than radar
as it uses only 1 watt!
