=Accuracy=
Out of the box, a Footpod is typically accurate to 90+% and after calibration this typically improves to 98-99%. This compares well with the accuracy of GPS which is 97-98%. However, a Footpod only gives you this accuracy on smooth surfaces where your stride is reasonably predictable. You need to make sure the Footpod is well attached to your shoe; if it's bouncing about the accuracy will be poor. If you do trail running, I found the accuracy can be rather patchy. Of course if you're running a twisty trail with tree covered, you may find the accuracy of GPS dropping to 80-95%. I have found that a Footpod provides vastly more accurate information for your current pace compared with GPS. While the errors in the GPS signal even out over the course of a run, they can result in a current pace that is inaccurate by 1-2 minutes/mile.
The Footpod will provide an accurate display of your [[Cadence]], which is a critical and often overlooked aspect of running.
=Using a Garmin Footpod=
If you have a [[Best Running Watch|Garmin 910XT, 310XT or 610]] then it is possible to display your current pace from the [[Pace From A Footpod ]] while getting other data from the GPS. I believe this is the optimal configuration for most runners. In addition, I found that turning the GPS off and relying on the Footpod dramatically increases the battery life of a Garmin watch.
=Bluetooth Footpods=
There are a number of Bluetooth Footpods on the market, but there are various compatibility issues.
