I've been using the Proxalert R-5 for over 2 years. I think this model was
originally designed for use in gliders, but it functions just as well in
power aircraft too. Optimal location is on top of glareshield. The R-5
provides more info than most other passive transponder alert devices,
showing up to 3 threat aircraft and their transponder codes. The xponder
code lets you know if they are talking to ATC, in which case, assuming you
also have a transponder, then they probably have been told about you.

Just became aware of this neat little device in the most recent soaring
magazine. A friend of mined saw the ad and called to ask if I had ever
heard of it. I replied, no I had not.
This device is supposed to identify the presence and distance of aircraft
transpoder bands. Small portable system with intregated antenna.

Anyone have this device? If so, please tell us what you think.
