Manufacturer's Description (July 11, 2008)

Easy to learn and simple to use, the waterproof Garmin Oregon 400i features a high-sensitivity GPS receiver and preloaded U.S. inland lake and navigable river maps that provide boaters and anglers with shoreline details, depth contours, boat ramps and mile markers for thousand of lakes. The chart detail includes shoreline, depth contours, navaids and port plans. It also offers a high-resolution, color 3-inch touchscreen that reacts as you tap or drag through menus and options. With its high-sensitivity, WAAS-enabled GPS receiver and HotFix satellite prediction, Oregon 400i locates your position quickly and precisely and maintains its GPS location even in heavy cover and deep canyons. It's also equipped with a barometric altimeter and electronic compass, and it's compatible with Garmin's heart-rate monitors and speed/cadence sensors.

The Garmin Oregon 400i.

It also plays well with others, allowing for wireless exchange of tracks, waypoints and geocaches between other Oregon units and Garmin Colorado models.

This unit has a built-in electronic compass that provides bearing information even while you're standing still, and its barometric altimeter tracks changes in pressure to pinpoint your precise altitude. You can even use the altimeter to plot barometric pressure over time, which can help you keep an eye on changing weather conditions.

Conveniently plug in optional preloaded microSD memory cards for all your outdoor activities on land or water. The card slot is located inside the waterproof battery compartment, so you don't have to worry about getting it wet. Just insert an optional Garmin MapSource card with detailed street maps, and the Oregon provides turn-by-turn directions to your destination. Add optional topographic maps to take advantage of the Oregon's 3D map view which gives you a better perspective of your elevation. And with optional BlueChart g2 Vision maps, you'll get everything you need for a great day on the water including depth contours, navaids and harbors.

Garmin's HotFix capability automatically calculates and stores satellite locations, greatly reducing satellite acquisition time so that you can turn the unit on and get going. Geocaching is even easier with the Oregon, which quickly downloads online information for every cache, such as location, terrain, difficulty, hints and description, so that you don't have to tote printouts with you.
