Casio pro trek seems to do more but the Pathfinder seems to be a little more accurate. I'd highly recommend both. the protrek also reveals more at first glance. both are great for camping hiking bugging out and everyday use. its always good to have a back up compass. and knowing how high or low you are can also help when navigating a map. the barometer can help you track weather patterns and give you a notice when bad weather is coming.
