Make sure you spend time setting up your presets, contacts, and quick text on the explore.garmin.comsite before you go out in the field. You also need to sync the device with the Garmin Explore smartphone app to send the messages and contacts to your 66i. It does not sync over the Iridium satellite network.
Garmins GPSMAP 60 ($320; www.garmin.com) is another good choice. It has similar features to the Magellan, but without the color screen. Its waterproof, comes pre-loaded with North American mapping software, and can take a wide range of additional maps. A color screen and expandable memory are available for a higher price in Garmins 60-Series line.
Both of these units can be mounted to a cradle for security. Or, you can buy a wrist-mounted unit, such as the Garmin Forerunner 205 ($268; www.garmin.com). Designed for hikers and bikers, it works well over water, too. You give up some screen size and readability, but you have tracking right with you all of the time.
