Hi tech gadetry with all the whizz bangs and bells is all very well, but a lot of these posts seem to be straying from the basic principle of VFR flight, see and be seen.
If youve got your head down looking at gadgets, you aren't concentrating on what you should be doing, and having one lookout is all very well, but two or three is potentially flying by committee.
Take advantage of any service from a rdar unit, even with a FIS we will endeavour to give you as much radar derived traffic information as we can, but when flying in such busy airspace we can only do as much as the traffic levels permit, the rest is up to you.
