** GPS is easy to use and accurate enough for most running, but it is not accurate enough for things like interval training.
** The errors in GPS average out over a run, but they cause a problem when trying to display current pace.
** I have [[GPS Accuracy| Analyzed the Accuracy of Some GPS watches]] for those interested in learning more.
* '''Waterproofing.''' Even if you don't swim, having good waterproofing is important to prevent your watch being destroyed by the rain or sweat.
* '''Current pace from a [[Footpod]].''' A [[Footpod]] can be used to provide [[Cadence]] and in some watches it can also provide pace and distance. Unlike GPS, [[Footpod]]s need to be calibrated to provide accurate pace/distance.

* For races where the GPS track is not important, you can extend the battery life by turning off the GPS receiver and use the [[Footpod]]. After 12 hours of running I still had 85% of the battery left. If you're running on a reasonable smooth surface, the [[Footpod]] is often more accurate than GPS.
=The Best – For Swimmers - Garmin 910XT=The {{Garmin 910XT}} is an improved a version of the 310XTwith extra features, but it's about $150-$200 more expensive. It can record laps when swimming, and is better at recording altitude, but it's only recommended if you need those features. If you don't need them, then the 310XT is better value. (It's available with the [[Heart Rate Monitor]] as {{Garmin 910XT with HRM}}.) Nearly all of the pros and cons of the 310XT apply to the 910XT, so I won't repeat them here.
