I'm sure it's a good product,because I've seen samples,from which I learned couple of things
but still price is quite high,maybe because it has simulator built in it,not just theory,but as for me I'm doing OJT,so I have high fidelity sim at the Unit,where I can practice things,I can try it even in live traffic situation,but what I need is theory and rules of thumb,let's say like 50 deg right/left for straight in coming acft will double his time till FAP
but 1250 $ for theory,well I need something more cost effective
I think most Training schools luck on teaching vectoring techniques,they usually use swim or sink principle
