OLYMPUS TG TRACKER
This nuggetty cam is an adventure companion, as it not only tracks your location via GPS, but also your vertical gain. An electronic compass also comes in handy for when you go well off the beaten track, and it’ll continue to track your location even when the camera’s turned off (though this drains the battery). It’s truly robust, and the Tracker offers bright footage in Full HD - especially 30fps, though 60fps strikes a sweet spot. 4K video loses clarity when flitting between high and low contrast areas, but plentiful mounting options make it a true contender.
