The lack of weather information on most handheld GPS units can be a real problem. The Bushnell ONIX 400 ($500; Summer 2008) uses XM satellite broadcasts to grab real-time weather information, including Doppler radar, letting you know exactly what's going on around you. Plus, the 400 boasts a rugged waterproof design, a rechargeable lithium ion battery, a vivid 3.5-inch screen, and, since it's already getting weather info from XM, it can also tap into over 170 channels of radio, keeping you entertained out there in the great outdoors.
The Air Suit ($1,250) will let you zoom around like a giant flying squirrel during your next lunch break sky dive. The suit's resistance-based design lets you fly/glide instead of just falling/praying. But don't plan to buy one of these and jump off your office building to save the citizens of Metropolis — Air Suits are custom-fitted and sold only to "seasoned" sky divers.
