I am ordering SE2 on the basis that ADSB is growing and promoted by our CAA. The alternative proprietry systems, cuŕrently popular, could soon be overtaken by this pan uk band. The principal other attraction is that se2 is self contained and can be put in the best and most convenint place on board. WiFi will tell my largish screen mobile on free fms where adsb planes are. That too is stand alone. Thus no wires, panel mods etc. Must make sense as we should all expect to be required to use adsb out in the nextcouple of years.
