Raymarine/TackTick

[Svalan]

Dear members of CF. I consider installing a wireless Raymarine/TackTick wind, speed, log, depth package to replace my old Autohelm instruments which are increasingly imprecise. The wireless aspect of the system and the theoretical ease with which it may be installed is attractive. My boat is a Hallberg Rassy 42 from 1999. Do any of you have experience with the4 above mentioned?

Thanks.

They do seem attractive but I wonder about battery life and as they seem to be powered/charged by solar, what happens when birds poop on the little solar panels (masthead)
