As you battle your way into the great outdoors on a bushwalk or camping excursion, you need both hands free for pushing away branches or fighting off wildlife -- not handling a compass. So to guarantee you're still headed in the right direction, this vibrating compass will always keep you aware of true north without requiring you to stare at a needle.
The anklet uses a set of eight vibrating pager motors equally spaced around your leg to subtly indicate which direction is north. And eventually your body will adapt and tune out the vibrations, giving you your own spidey-sense of which direction to go. But be forewarned: the $160 North Paw needs to be assembled, so in addition to knowing how to tackle mother nature, you're going to need to know how to solder as well.
