The Topcon GR3 looks more like a heavy-duty flashlight than a GPS receiver. It looks like the kind of tool that Bruce Willis would use in one of the Die Hard movies to bop the bad guy over the head—or Ashton Kutcher if he's being a cheeky beggar. Really a tool for surveyors who need pinpoint accuracy—it uses 36 satellites to give you results down to the last millimeter—the GR3 is built to withstand the most extreme weather conditions. It has just won a prestigious award in Germany (making it more like David Hasselhoff than Mr T, perhaps) for design. But it's expensive: you won't get any change out of $22,000. – Ad Dugdale
