This product will connect to your phone or tablet via Bluetooth to provide GPS location and ADSB-In, so you will be able to see where you are, where traffic is, and receive weather at nearby airports. I have used this during my work as a corporate jet pilot and a flight instructor, and it works well at all altitudes. I have used this with a number of apps, including ForeFlight, FltPlanGo and WingX.
