I bought my pathfinder to have both the barometer, altimeter, thermometer and compass. Worked very well to check updates on low-pressure storms swooping in quickly in winter in the Inside Passage between Alaska and British Columbia. Saved my a** a few times. Even though this behemoth of a watch takes up like half my forearm (being 5'1" 98 lb female) it's worth it. Casio does however get my award for just another company that, in making watches with all of these functionalities only for men versus as well as women, suck.
