I have B & G instruments which are 20 years old and work well.
speed sender needs replacement. I don't like the technology using a flimsy plastic anemometer which birds perch on and have bearings which fail frequently. The smallest and cheapest parts
cost more than $100 US. I was told that I have to replace the whole sender and mount because mine is too old.
I have chosen not to repair it since I can judge wind
and seas close enough without reading a gauge.
My depth sounder
is old and still works. It is difficult to read (red blip) and I would prefer an accurate digital model for inshore hazards.
I do like the wind direction and point of sail indicators.
I have found on previous boats that all brands are expensive to repair. B& G have a good reputation.
