new toy on the market called Trafficscope. Shows closest aircraft and their altitude difference. I think it is a great tool for avoiding other aircraft. If you can, try it out. most shops like marv golden offer a 30 day gaurantee. http://www.marvgolden.com

I couldnt agree more. I just received mine after waiting abt 2 weeks. I guess there was a small backorder situation. Unit works great. I had to fly to Colo Springs on business and the unit started reporting an aircraft at 5 miles. When it got to 1 mile and 100 ft below and I still couldnt see it, I asked flight following if they knew where there was an aircraft at 1 mile/-100 ft. After a pause, they said yes there was, and how did I know? I told them I had TrafficScope. Nevertheless, it made a believer out of me. I wont fly without it.
