I bought a TrafficScope VRX and so far like it alot. One knock is that the
internal altitude readout is often off by about 300', this after getting a
1-minute AWOS altimeter. BUT, the alerts are nearly always dead on in the
vertical plane. Another knock is if you have more than one alert, it'll
rapidly switch back and forth between them. It's designed to do this, it's
not a defect, but it can get confusing sometimes. I don't like how if your
plug comes loose on your cigarette lighter the unit will just turn off, it
wont revert to battery power if the plug is plugged in to the back. Sure,
it lets you know of a possible electrical failure, but you have to boot it
back up which takes a little time and start searching again for traffic -
which seems to always be around where I fly.

The default power on volume is full blast, not fun when put into your audio
panel. The lady's voice gets old, but like I said, it stays pretty busy
where I fly. I get alot of ModeS indications, and wake turbulence warnings.

Like I said, the alerts are pretty accurate, we often see the traffic before
the controller calls it. The display is easily viewable, day or night,
tells you quick what you need so you can get your head back out the window.
I dont find myself staring at it.

Who cares about the codes, I dont. So the Monroy unit has to have your own
transponder responding, and also your mode C replying? As a controller
theres lots of times a transponder occasionally doesnt put out a signal or
ModeC, regardless of position. Interrogation doesnt guarantee reply.

Prior to the VRX, I was leaning towards the Monroy, partially based on
Aviation Consumers report. But they, and Proxalert, at least by their
websites, sure don't seem as professional or informative as Surecheck.
