I cannot begin to tell you how useful this tool is in tracking
trafffic around us
For $1500 !

But it will only show planes with certain non-mandatory equipment, if I
got it right? Is it not like radio at a non-controlled aerodrome, a nice
extra source of info but nothing to really count on?


If by "certain non-mandatory equipment" you mean a mode C transponder, yes.

However, there is hardly any place in the US with significant traffic that
most people don't have a mode C transponder.

The places were there are few transponders tend to be well removed from
major urban areas and full of things like gliders, sky divers, ultra lights
and such.
