Garmin introduced two new products in the forerunner series, Garmin’s popular GPS-enabled fitness product line, the forerunner 205 and 305. These two new GPS devices have been completed redesigned (and imho they look much better). However, besides the new look the redesign of the forerunner series serves also some functionality purposes.
