We found the performance of XRX to be first-rate. It is well thought out and impressively engineered. When combined with a Garmin 496, it provides a remarkable effective traffic awareness system at a realistic price.

Conclusion: the MRX is the ultimate in really portable traffic detection systems for pilots on a budget.  These products are a pilot's best friend in busy airspace and it truly is amazing how it picks up traffic before you can possibly detect it yourself. Priced at USD499 it is a no-brainer to order one right now and make flying for you and your passengers much safer."

We were impressed with the XRX’s range and azimuth capability. Conclusion: We’re impressed with the XRX and we think it’s the most capable portable traffic device we’ve seen yet."
- XRX Review, Aviation Consumer, August 2006

"Watching Your Six Never Was Easier… We have reviewed a number of Portable Collision Avoidance Systems (PCAS) from Zaon.  We had the opportunity to flight test their latest model in traffic detection systems which not only includes information on relative altitude and range but also in which direction to look for traffic, in other words quadrant bearing. The ZaonFlight XRX is a huge improvement over their previous top model and well worth the investment in making your skies safer."

Impressive Performer. For $475, the MRX’s performance is hard to beat. Although it lacks azimuth, it reliably tracks the closest target and gives spot-on range readings. Zaon’s MRX is the smallest traffic minder yet and, according to our trials, the best performing."
