The Garmin 705 Mounted to my Touring Bike
GPS Units Are Useful
Affordable GPS units are tremendously useful, enabling scientists to track global warming, drivers to save fuel, indigenous groups to document environmental destruction, and so on. GPS is also used for fun and recreation; for instance, geo-caching is a popular “high-tech treasure hunting game played throughout the world” that gets people outdoors, and for several years Garmin has sold GPS units for bicycles that display speed, distance covered, etc.
Combining the Fun and Functionality of GPS
All this is great, but what if we could combined the usefulness of GPS technology along with the fun? Well, I recently purchased a Garmin Edge 705, which does just that. The 705 has all the features of a standard GPS bicycle computer (speed, distance), but it also provides turn-by-turn directions and maps anywhere in North America. Bicycles are already the most efficient form of transportation, but getting lost on a bicycle (especially at night) is not only tiring and frustrating, but can potentially be dangerous. So I was especially excited about putting the 705 on my bike and testing things out.
