Currently I have a Ray ST60 system on board for depth
, speed and wind
.I also have a r70 radar
, garmin gps
(older model) and a hand held gps
instrument died, and I since I am planning in the future to change to a networked garmin chartplotter
like the 4212, I wonder if it would be better to just go with that system, the garmin wind and sounder.
This would give gps, speed over ground, depth
, wind. The only thing it wouldn't have that I know of is speed in water
, as there is no speed transducer that I can see.
So the question is, why would I need this, instead of the speed via gps ?
I understand the gps might not work someday, but then raymarine
instruments fail as well. Anyone have something like this on their boat ?
