most important safety item is a transponder.

I strongly disgree with that position. A PCAS offers the host
aircraft pilot increased awareness of all promimate transponder
equipped aircraft. A transponder offers the host aircraft pilot no
increased awareness of proximate aircraft unless receiving ATC
services. It also provides pilots of proximate aircraft no increased
awareness or protection unless they are either TCAS or PCAS equipped ,
or are receiving ATC services.

Off all the near misses I have had in 30 years of flying gliders I
estimate that none would have been avoided by my having a transponder
and nearly all of them would have been mitigated by PCAS.

Please note that I am not arguing against transponders, only about the
relative merits of PCAS and transponders.

I only have one MRX but it is portable and I seldom fly anything
without it.
