Taking a PST on an airline

Hi to the group,

I'm off on holiday to Mallorca and was wondering whether to take a Coronado
PST with me. Has anybody had any problems taking a Coronado PST on an
aircraft? Is it best to take one as carry on hand luggage or to put it in a
suitcase in the aircraft hold?

With the current high security requirements I was wondering what the best
practice is.
Has anybody had any security problems, experiences etc. ?
