WR - the reality is that your super duper unit (do tell us where it is) probably has something that chevvers is wanting: That is, a good old radar display which is not a computer screen. ie good solid primary returns like the ones we used to have - not a "+" for a primary return and a "x" for a secondary return.
Computers are used nowadays to interpret and display the returns on our screens. They surpress most of the primary contacts that are slow and low/even composite aircraft.
Dpn't be lulled into always believing you are clearly seen.
