Our boat has got an oldish but generally satisfactory electronics
suite -- Raymarine
RL70RC+ and RL80CRC+ displays/charplotters, 4kW Pathfinder radar
. It doesn't do AIS
and the cockpit
display is monochrome, but I think it will do fine for a couple years. If you upgrade your electronics
every time a new generation comes out, you will be broke very quickly, I say.
When we bought the boat last year everything worked fine. But this year all of sudden the system can't figure out the boat's heading, and the radar
started working intermittantly . Sometime the heading is shown correctly; sometimes it's off by 90 degrees or more.
continues to work fine (and I don't understand how it can, but it does) but the radar won't do its MARPA thing.
I have searched and searched for the obvious thing -- some metal near the fluxgate compass
, which is mounted under the saloon
Next thing I'm going to try is the connections to the fluxgate compass
-- look for a bad ground or bad wire connection.
Any other thing I should look for?
Do these things typically go bad, requiring replacement?
And if I do end up having to replace it, any tips on which unit to choose?
Thanks as always for your words of wisdom.
