The Nightfox Arctic that Rummbolt reviews in this video is a thermal imaging device designed for airsoft players who want to spot their friends—or enemies—based on heat rather than lucky guesses. It comes in a sturdy box with a manual that is actually readable, which is a nice change of pace for tech gadgets. He says the device is surprisingly light for its size, so you won't feel like you’re wearing a brick on your forehead during a long day of running around the woods.
