As a sailor and yacht racer I have always admired some of the products from Garmin, but I was at the London Boat show with Dave Oliver and was pleasantly suprised with some of the newer GPS units from Garmin.

Their latest for Cyclists is the Edge 205 and Edge 305. Both are pretty similar providing:
- Easy-to-install—no calibration required. Just snap it in the included bike mount and go
- High-sensitivity GPS receiver—knows your position even in tree cover and canyons, making it extremely reliable for navigation
- Customizable cycle computer—shows up to eight different data fields for continuous feedback
- Virtual Partner™—lets you "race" a virtual competitor, making training fun
- Courses—lets you "race" against a recorded course to try to match previously set speeds at every point along the way
- Auto Pause™—pauses the training timer when you slow down below a specified speed and resumes when you speed up again so you can focus on your ride
- Auto Lap ™—automatically triggers a lap every time you pass a specified location or travel a preset distance
- Training Center software—gives you the ability to create workouts, manage and download courses, and create a detailed post-ride analysis that charts your performance
The main difference being that the 305 provides is it's available with either a heart rate monitor or a wireless speed/pedaling cadence sensor
