The units are Garmin Dakota 10 or Garmin 76csx. These devices have a small screen (1.5”x2.25”). If you have trouble reading text up close, you should purchase your own with a bigger screen (like the Garmin Montana 710i). These units come with RAM mounts for mounting to the handlebars of your bike, and pre-loaded tracks for the event. There is no charge to use our GPS devices, but you will be charged if the device is lost or damaged. This product is only available to No Wimps clients.
