GPS products for extreme sports are becoming popular, but the TRACE has to be the best implementation of form, size, and functionality we have seen yet. This small device clips to you or your equipment and uses GPS sensor technology to track your session whether you are snowboarding, surfing, biking, running, and so on. TRACE works to minute details too, able to track and record every little move or trick you do, and you are then able to share it or the whole session with friends. US$99+
