TIS demonstrated it's worth to me in the first ten minutes I flew with

was getting flight following the thing showed an approaching aircraft

I am very happy with my TIS as well, especially in the very hazy
weather in the northeast US. I have a Garmin GTX 330 transponder that
feeds its traffic data to both a GNS430 and an MX-20 moving map.

After almost one year of flying with it, the only two complaints about
TIS that I have are the relatively limited coverage areas outside of
the northeast coastal megalopolis



ADS-B is rolling out on the entire East Coast. http://www.flyadsb.com/.

For once my home state, North Carolina, is looking forward and has
already established coverage over 95% of the state and is looking into
ways to get the rest (primarily mountainous areas).
