Barometer? yes. Compass? yes. Thermometer? yes. I love it, plus you get software upgrades. From what I understand there was a problem with the 1st generation of these where in the case of multiple victim burials there were "ghost" signals. If you have an old one you can send it in and get that fixed. I would have sent mine in but I had to trash it because the screen was smashed and Pieps said there was nothing they could do to fix it. They did offer a generous deal on a new one. I wouldnt use this for snowmobiling because of the likelihood of smashing your core area on the handlebars, but other than that, this is as very useful piece of equipment.
