Used Satloc Bantam w/ 7" X3 Screen & L7 Lightbar. This is a complete system that comes with everything you need; CPU, Screen, Lightbar, Antenna, and all wiring. This system is in good shape! All used systems are bench tested before shipping. I guarantee all used systems to work upon receipt. Install the system, go make a few test runs up and down the runway to ensure everything is working. If you find a component that isnt working, I will replace it for free! After this point, there is no warranty.
