Bests & Worsts Reviews from Amazon

First off, great watch! I did a ton of research, and searching forums and reviews about this watch before I bought it. Let me tell you, there are a ton of flat liars out there. I read so many forum posts and reviews that the person had obviously never even handled the watch. Im a Harley technician by trade, and was interested in gshock durability. Yes I could get a protrek with the same functions for less, but I doubt they would survive. Now for the watch itself. It has a great weight to it, feels more like a watch than most gshocks. The metal buttons are easy to push and feel great. The led lume is plenty bright, and the display is intuitive. All the standard gshock features work great, if you set your longitude/latitude, everything is spot on except that the atomic portion won't sync. So if that's a deal breaker you have to deal with sunrise sunset being off up to 30min depending on your actual location vs. selected city code. Now for the barometer/thermometer. Ok first the thermometer in the watch is used for sensor operation, not really to take a temp reading. If your wearing the watch it reads skin temp. Not a big deal, I can tell if it's hot or not. That being said I had to calibrate my temp, I left the watch alone for an hour on a counter with an accurate thermometer next to it. Then adjusted temp to match. Once that was done I calibrated the altimeter to my actual elevation using topographical info for my exact position. The barometer itself after those two adjustment were close to the local weather reading. The barometer graph works well when you are stationary, or very gradually change altitude. Live 300' higher than my shop, so there's always a jump in the graph from home to work and work to home. The baro/alarm works great, again without major altitude changes. If you are hiking it works, I had it go off, looked around and thought it was acting up. Nope, two hours later it started to rain, then the alarm went off again, the baro shot back up. That indicates high winds in a storm, and boy did it storm. Ps. Atomic will not sync with baro alarm on. Altimeter Accurate, but effected by weather. I have a friend that's Special forces airborne, he has always told me altimeters need to be adjusted to a known altitude before you use them. It's no different for the watch. That said it has been accurate enough if my gps was toast, I could navigate a topo with it. It's usually within 40-50 ft max so far without further calibration. I have a garmin 60csx and the altimeter usually matches within that range. Compass. It's a digital compass what more do you need. Metal and electronics mess with it, but mechanical compasses have the same affliction. Again, properly calibrated, with a good topo, I can navigate with this watch if I had to. Would i head out with just the watch, no! But I'm not stupid. I usually take an extra compass, and spare batteries for the gps as well as quality topo maps for the area I'm in. But if everything else quit, I could find my way with the Gshock Rangeman. Are there better systems out there, yes. Sunnto makes a watch for navigation, but it's not solar! Batteries tend to run out at the worst times. Garmin makes a wrist mount gps, but I have a hand held. I primarily use my rangeman as a watch, second as a barometer. You just have to know and understand the limitations of the features and learn how to properly make use of them. It's a great looking watch and has taken a beating, it still performs for me every day.
