I use this unit. It works great. Keeps me alert of traffic so I can look out for slower traffic that does not use a transponder.
I fly from a small airpark that has a fuel stop for the local Air-e-vac team. Some times these guys and gals come in a few times when I am flying. Now I see them 5nm out and can keep an eye out for them long before I see them with the naked eye.
For the buck its a great little unit and sometimes you can pick up a used unit as I did and save some cash.
