** '''Compass'''. A magnetic compass can help you orient yourself or the map. Without a magnetic compass you have to be moving for the GPS to give you a sense of direction.

* '''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 Ambit3 supports [[Cadence]] via a [[Footpod]] or it can estimate Cadence from it's internal accelerometer, though I've found the internal accelerometer can be out quite a bit. Sadly it has no alerts for when your Cadence is too low.

=Which Version?=

The Ambit3 comes in five versions with different functionality. I think the "Run" has the best value for money, but depending on your usage you may want to pay for a more expensive version. If you're a cyclist, the "Sport" might be worthwhile, though I won't comment further as I focus purely on running usage. If you're an ultrarunner, then I think the "Peak" version could be well worth it. The Sapphire is only worthwhile if you're hard on your gear and want the damage resistance. A new version called "Vertical" that is part way between the Peak and the Sport versions. One intriguing difference for the Vertical version is that it can make use of the Russian version of GPS called GLONASS. This suggests a different GPS chipset, so the accuracy could be different to other versions. (They all use SiRFstarV, but that's a family of chipsets. For instance the [http://gpsworld.com/csr-launches-sirfstarv-5e-gnss-location-solution/ SiRFstarV 5e version supports GLONASS].)
