The Pathfinder PAG-40 is the USA variant of the
ProTrek PRG-40. For some reason the ProTrek models are called Pathfinder
in the USA alone. The PAG-40 was the last non-solar ProTrek/Pathfinder
model and is the predecessor of the PAG/PRG-50.
The PAG-40 was clearly worn in the movie "Man on Fire" by Denzel
Washington. WHen I got it I was surprised it had a reversed EL
Backlight. It looks pretty cool.
