Today I'm wearing my newest Pathfinder, a PAW-1300T-7V. PAW for Pathfinder (in the world outside the U.S.A. these are called "Protrek" and the model numbers start with PR,) 1300 for the series (newer than my 1100,) T for Titanium, 7 for silver accents, and V for international (non-Japanese) version. This has all the functions of my PAW-1100T but weighs less and is much slimmer (only 11.5mm thick, while the 1100 is over 14mm thick.) This was the ultimate Pathfinder, all the functions available in a Pathfinder in a package that made it very wearable under most conditions. Of course, Casio couldn't rest on their laurels, so the PAW-1500 series is the newest King of the Hill, which adds tide graph, moon phase and 200m water resistance to the long list of features. I'm not sure if I'll get a 1500 or just wait for whatever comes next. It's almost certain that Casio will keep improving their technology and packing more features into smaller, more durable packages.
