Eric,

I'd guess he is using the Proxalert R-5. I've got one and like it. It
tracks several and displays the 3 most significant treats along with
their squawk code (so you can tell if their are talking to ATC or
not). But, the R-5 is much larger than the tiny Zaon MRX - - I had one
of those too, and it displays only the most significant single threat
like the PF. The additonal functionality of the R-5 is nice, but the
MRX gets the job done. I figure I can only dodge one at a time
anyway. If there's two coming at me at once, the plan is to wait 'till
the last moment, duck, then turn and watch the confusion.

I tested the R-5 alongside the PF in the Husky - - about 3 inches
apart. Half way through the flight, realized the R-5 was interfering
with the PF, so had to toggle power on and off to test and compare
PCAS function in both. The PF PCAS works as well as the R-5. In
addition, the PF displays discreet info on ADS-B out aircraft, and way
out at 32 nm.


My understanding is the MRX will track more than one target, but only
display the greatest threat. Not quite as informative as the R-5, but
perhaps better than it appears from just the display.
