The 213MHU's from b&g are known for electronic board failures, the board cost around 350, the whole unit cost around 1200, the cable costs around 350... if you're on a regatta
boat only b&g and NKE are able to steer the boat efficiently, but as a cruising/occasioal regatta
boat the only one I feel to racomand is the raymarine, not only they keept the compatibility from the first autohelm
till the newest itc5, the spares are cheap
: the whole new trasducer is 350, the electronic board is 120, the 30m long cabl is 130... When onboard you have problems with the gooseneck in the mast (it "bruises" or "eat" the cable insulation) you have the same problem either is a b&g or a raymarine....
Last week I had the first call with a garmin wireless trasducer that around 3 am it stops working so i guess the battery is near to it's end of life...
Then there is always the availailability of the spares part, for b&g and raymarine you can find people that know how to troubleshoot and have the parts
in stock or you can order them with short waiting times, meanwhile for all the others the waiting times are longer and the technicians have almost non clew on how to solve the problems...
Then the most annoing thing is that in a couple of years you'll non going to find anny king of spares on systems like garmin, humminbird ecc, do I have to remember you systems like standard horizon, Geonav ecc? the jhonson group that made geonav closed everything and now they are selling the geonav systems as huminbird but modified the firmware so that the old geonav parts
are not compatible with the humminbird systems, I have an autopilot
payed 4000 with a small problem that humminbird will not fix and now they do not sell only the cpu and display but they only sell the complete pack so the client has to buy all new again... You have the same thing with the garmin wind wireless trasducers since they are wornig on different radio
frecvencyes on US and europe
and seems that garmin will only make country specific models from now on (untill now you had double frecvency so depending on the country you where in tyou can chose the frecvency you like, as well as tacktick)...
*I'm doing marine electronics
as a job so I see 200 boats a year, on my youtube channel ElectronicMarine you can find a couple of videos with fixing solutions and troubleshooting tips, for now the videos are in italian but youtube will put subtitles for them in english*
