Also Regarding Bizjets i have positively identified some but not all through my local traffic log with network turned off as it seems to be be very accurate as soon as the signal is found and the Alert function is activated i have got my "bins" at hand and i look outside have quick look around and i have very rarely i may add bagged a bizjet ,some at high altitude on a clear day.
As time goes on maybe more bizjets will have the capability or will have to use this function.
I agree with Roadrunner if bizjets is all you want then its a lot to fork out for a limited aircraft field .
But so far mine has been excellent and i have bagged loads a superb investment as far as i am concerned
