Amazing accuracy and fast satellite acquisition time. So simple to set up and use, you will actually use it.

The 305s ability to both track, and maintain a lock on, your position is better than anything before it.

Not only does Training Center--which is compatible with both PC and Mac--make it easy to track your performance, you can graph data such as heartrate alongside your speed and distance.
