MiraTrex PRO CHARTS™ is a powerful, yet easy-to-use marine navigation system. Whether you’re a fisherman, weekend cruiser, sailor, diver, jet-skier, or an offshore captain needing to find an exact location hundreds of miles offshore, PRO CHARTS™ will get you there and back home safely – with nothing more than your iPhone or iPad. Key Features: • High-resolution NOAA nautical chart coverage with depths for all U.S. coastal areas, the Great Lakes, major U.S. river systems, and Brazil plus global high-level nautical charts. Charts are automatically updated based on NOAA chart corrections. • Easy one-touch Waypoint and Route creation. Pre-plan your routes at home or create them at sea with equal ease. Just touch the screen to create new waypoints and routes. • Find your friends on the water. With our new Buddy-tracking feature, you can see and meet up with your friends while you’re out on the water. If you’re on your secret spot and don’t want to be seen, you can hide your location with the touch of a button. • Stay safe. Easily create and send a Float Plan of your trip to a friend or family member. Your Float Plan and location history can be forwarded to search and rescue personnel in case of an emergency. • Easy point-and-steer navigation.

No Problem. PRO CHARTS™ is designed so no internet connection is required to view your charts while out on the water. You simply download in advance any charts you’ll need at sea with the touch of a button. • Record your tracks.
