The CRP-5 paired with an ASA Pathfinder was our schools mantra.
The pathfinders to get used to electronic inputting & to double check your "wheel" skills.
Probably just coincidence the club sold both at a heavy mark up.
Ebay always got round that annoyance.
Plus in the vain world of the club's flight planning rooms, whipping out a CRP-5 & pathfinder from the flight case, used to carry more kudos than crp-1's.
Cheers
