Shiva came new from the builder
with a B&G Hornet system which has worked for 21 years with virtually no problems. We did have a lighting
strike in the area which required a new "board", and one LCD has been replaced. But 21 years including several years of live aboard and offshore
passages is a pretty good record
Over those those two decades I have seen Signet and Datamarine come and go and who knows what other companies. As convenient as "wireless" is, running a wire once (and I didn't even do it) in20 years is not overly burdensome for an installation.
Position fixers are another matter. I have had a few Lorans... all with their own antennas... SatNav and several GPS
again each with a designated antenna
install and cable. I am about to add an AIS
so yet another antenna
cable to pull and antenna to mount.
I suppose in a few years there will be a better GPS
system and more antennas, but for now I am OK with the antenna wires. hahaha.
Telltales work fine for sail trim, but they do boo for navigation
