Really? I thought I got EXACTLY to the thrust of your post- which was that YOU didnt need think you needed ADS-B, so why have it? Or did I miss something?
Now if it stings a little to realise that running an argument against ADS-B because you dont PERSONALLY think there is any benefit to YOU smacks of an "I'm alright Jack" mentality, then so be it. Think about it, then see who looks like a prat.
