COLLISION AVOIDANCE

We can talk for hours about traffic aviodance, most systems are too expensive.
But the picture below, you don't want to experience in real live !!

Goodrich SKYWATCH (Reg. $19,995) TCAD 9900BX System (Reg. $20,200)
Ryan TCAD 8800 Gold (Reg. $7,200)

Yes your eyes are OK....nice prices.
If you are not fully loaded with money two systems are available:

SureCheck RX-110 TPAS (Traffic Proximity Alert System) $549 Voice warnings example

The Monroy ATD-200 $695
Voice

We have chosen the ATD-200, because of it size !!

We had some negative reports on the TPAS system, from avionic resellers
and tests. The ATD was superb !

The ATD-200 cannot share the existing transponder or DME antenna.
But ... the ATD-200 will work fine with the old DME antenna.
