Hi
I use the What was Tacktick (now Raymarine) wireless
mast head wind to T122 wireless interface which allows the
NMEA 0183 info into the main
Raymarine system , I also have the Tacktick readout
Solar powered and demount-able). My mast
head is 17 meters from the interface/readout & no problems with communication. I have had to replace the masthead unit once when the bearing gave up - but it was reconditioned so I now have a spare.
Benefit - no instrument wires in the mast.
