The {{Polar V800}} is elegant and has outstanding [[GPS Accuracy]], but it's pricy and has less functionality compared with its competitors. The functionality of the V800 is steadily improving as Polar release newer versions of the firmware and the accompanying web site. For a simple evaluation of a GPS watch, I look at how well it can answer some basic questions:
* '''How far did I run?''' This is the most basic question, and the V800 has outstanding GPS accuracy. If you really want to know how far you've run, this is the best option short of running on a track.
* '''How fast am I running?''' Knowing how fast you're running can be a nice to know, or it can be vital for your training or race performance. Because of the nature of GPS, watches that rely on GPS signal alone tend to have serious problems with current pace. Without the ability to display current [[Pace from a From A Footpod]] while getting all other data from GPS, the V800 has a poor display of current pace. Even with the outstanding GPS accuracy, the current pace can be a long way out. (This is mostly due to the nature of GPS accuracy errors compared with Footpod errors.)
* '''Where am I? '''The V800 has no navigation features. If you're lost, the V800 is probably only useful as a reflector to signal for help.
* '''What's my cadence? '''[[Cadence]]''' '''is one of the most critical and often overlooked aspects of running. If you get your Cadence right, many other things naturally fall into place. The V800 has limited support for a [[Footpod]], no support for Cadence from the internal accelerometer, and no Cadence alerts. It's better than nothing, but it's not pretty grim for a high end watch.
