“Bushnell ONIX 400 GPS with XM NEXRAD Weather” for the astonishing is $100. This is the same kind of technology that’s used by most stormchasers in their vehicles, only on a much smaller scale – and of course, instead of taking the data from your own radar, it’s just pulled alongside the GPS data.

The device also has a 3.5″ display working on a 320×200 resolution, satellite imaging, an SD card slot – and it comes with a 128 MB card. The battery holds on for about 30 hours, and the device is waterproof as well.
