Hello,
Sorry to jump into your exchange ... You may consider trying a Prox
alert R5 which monitors up to three threats simultaneously.

Don't ask me to elaborate online on other devices since i work for
Prox alert.

As we are an honest company we have no problem to offer a 30 days
money back guarantee. www.proxalert.com (HQ in Phoenix AZ)

We will be happy to answer your technical questions about affordable
collision avoidance devices.

Thierry, I like the target squawk code readout as well, but it comes
at more than double the price... Still alot cheaper than the $19k
units that are out there too... G
