No 'perhaps'. Definitely..

Interesting bit in Tchocky's link:

The pencil beam is very thin. Nowadays this necessitates (or should necessitate...) re-ident...
It's a horrible feeling when that blip disappears with a ULE examiner standing behind. Bit difficult to explain to him that one gets used to vectoring 'parcels of thin air'..."don't worry, it'll re-appear" is no longer acceptable!
If there are two blips in the beam they could be somewhat close...
If there are two raindrops in the beam you might as well go home...it's a great weather radar!
It's also fine in CAVOK...when the crews don't need radar...
