I installed a TackTick T101 system on my boat a couple years ago after a lightning
strike took out my old wired indicator. For the most part it has been great. It does periodically lose connection though. This is usually fixed by just turning it off and back on again, but not always. Sometimes I just have to wait awhile and it comes back to life. Most of our sailing is in the lower Ches Bay near the Norfolk Naval Station. My theory is that something on the base interferes with the signal. If you consider wind speed and direction to be critical information, then you might want to stick to a wired system. If you can deal with the occasional outage, I would go with the wireless. It's just nice to have for me, so I'm pretty satisfied with the T101. The battery
life is excellent, and the install was super easy.
