Navman R300

For joggers looking for a little GPS guidance.

In our book, any GPS device designed for joggers should be for displaying the quickest route to the nearest kebaberie. Navman thinks differently. It's just launched a range of sporty products that use satellites to gauge things like distance covered, speed and calorie usage, in a way that a bog-standard pedometer could never match. The R300 is a small, light triangular box that attaches neatly to an upper arm. It's certainly accurate, but its two buttons are fiddly to use and we couldn't always see the display clearly to note our less-than-impressive speed. For joggers who care about that stuff, though, this is probably worth a punt.
