Joe, Which GPS model has that?  I'd be kind of curious as I easily fly a lot 
more miles than I drive.  About the farthest I drive is to the gas station 35 
miles away to get another 100 gallons of Mogas to feed the planes. :o)

BTW, I recently installed the SkyGuard Vision Pro ADS-B Transceiver companion 
to go with my iFly 720 GPS.  I have photos of the installation on my web site 
<http://jeffsplanes.com> on the instrument panel page.  I will likely add some 
screen shots of the TIS-B traffic overlay on the iFly720 after I get a chance 
to fly it a bit more this weekend.  

My first impression: This is not a replacement for the Mk 1 eyeballs, but it is 
nice to have it show you where to look to find traffic.  At most of your local 
airports, the traffic information will be less than reliable as much of it is 
Mode-C traffic that is picked up by radar at center, then rebroadcast via the 
ADS-B tower.  So, most traffic won't show up in the traffic pattern as they are 
likely to be below Center's radar, or if you are below the line of site from 
your local ADS-B tower, you aren't likely to receive the data even if they are 
on center's radar.  However, if the local traffic is broadcasting either Mode S 
with 1090ES or UAT you will map them all the way to the ground.  So, this will 
improve as more planes equip with either 1090ES or UAT transmitters.  While in 
the pattern, your eyes belong outside the cockpit rather than scanning for 
traffic on the GPS where it is likely to not appear.  Performance of the unit 
is likely to be significantly better near major hubs where the radar and ADS-B 
towers are both going to be close by.

The good part is for traffic while flying cross country.  While at altitude, 
you and any conflicting traffic are likely to be on Center's radar and within 
range of an ADS-B tower.  Under that circumstance, it's great for deconflicting 
with other traffic.  One caveat is that Mode-C traffic that is being picked up 
by radar and rebroadcast via the ADS-B tower has a significant delay, so the 
traffic is often times well past where they are being painted on the display.  
Traffic that is broadcasting 1090ES or UAT is depicted with an accurate 
position.  This unit would be all but useless in my SuperCub as I am rarely 
more than a few hundred feet off the deck.  But in the KR, it's a welcome 
addition.
