Garmin: making "out to sea" a good thing
Whether you're sailing the high seas or hiking the backcountry, Colorado 400C is your all-in-one adventure guide. Preloaded with BlueChart g2 coastal charts, Colorado is made with the saltwater mariner in mind. Map detail includes shorelines, depth contours, navaids, harbors, marinas, port plans, and coastal roads for the U.S. and Bahamas. It also includes 3-D map view, a high-sensitivity WAAS-receiver, a barometric altimeter, an electronic compass, an SD card slot, a JPEG picture viewer, and a transflective color display. Experience the freedom and camaraderie of exchanging tracks, waypoints, routes, and geocaches wirelessly with your other Colorado-toting pals. You can even do the unthinkable — give away your favorite place to hook marlin or watch whales, with GPS accuracy. The Colorado 400C is your professional guide to the wet and wild.
Goodies galore!
With its high-sensitivity, WAAS-enabled GPS receiver, Garmin's Colorado 400C locates your position quickly and precisely and maintains its GPS connection in the harshest marine environments. The advantage is clear — whether you're braving 20 foot swells, wandering the deep woods, or just in the shadow of tall buildings, you can count on your Colorado to help you find your way in when you need it the most.
Intuitive and fun, the Colorado also features a Rock 'n Roller input wheel for easy one-handed operation and supports Geocaching.com GPX files for downloading geocaches and detail straight to your unit. Customize Colorado's interface based on your favorite activity. Even show off photos of your favorite cove in the Bahamas with its picture viewer. As if that weren't enough to persuade you to reach for your wallet, the Colorado 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 (i.e. not have to use the life rafts).
Slim, lightweight, and waterproof, Colorado is the perfect companion for all your outdoor pursuits.
The new cool
Half the non-survival oriented fun of owning a GPS is placing and finding geocaches. Sure, it's geeky, but we all need to feed our inner geek from time to time. Lemme tell you, geocaching beats scrapbooking or stamp collecting hands down. And, in a techie improvement on standard dweeb practice, the Colorado 400C allows you to share your waypoints, tracks, routes, and geocaches wirelessly with other Colorado users. Now you can send your favorite hike to your buddy to enjoy or tip them off to the location of a particularly "cool" cache. Sharing data is easy. Just select "send" to transfer your information, then pat yourself on your sweater-vested back.
The Colorado 400C: for adventure in any direction
Conveniently plug in optional preloaded SD cards for all your outdoor activities on land or water. Just insert a MapSource card with detailed maps, and Colorado provides turn-by-turn directions to your destination. The card slot is located inside the waterproof battery compartment, so you don't have to worry about getting it wet.
