After flying with the ZAON collision avoidance system,we became one of their
dealers. You can find it on our web site listed below.

It was very interesting to have the device give warnings for aircraft I did
not see.

It works exactly as advertised, & seems well worth the cost, especially when
flying near high density areas such as we fly.
It receives it's data from other nearby aircraft equipped with a
transponder. Our glider also has a transponder.
