The Garmin Edge 305 is first and foremost a full feature GPS. With accessories, which include a heart rate monitor and cadence the 305 is an outstanding training device. as well as a ?history? resource when used with the included software, and a trip/ individual ride planning device for locations any where in the world
The only issue I with the Garmin 305 - after almost 11 months use - is the 305 has too many features. On the other hand, to accommodate the vast amount of features, the 305 does offer two customizable screens.
