A necessary safety aid for anyone flying in crowded airspace or flight training in proximity with other maneuvering aircraft, and a relatively tiny investment to keep you safe and violation-free.
This thing is amazing! You see other traffic, it has a solid GPS lock and is light and compact. Setting it up is a breeze. If you fly with an iPad you should have this unit for added safety in any aircraft.
My CFI showed me his Stratux build. After reading about the project online I decided to go with this unit to make sure everything was put together properly. Couldn't be happier with the device.
