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. The red heading bug on the large on-screen compass always directs you to the next point on your route. Navigation is as easy as pointing your boat at the heading bug to stay on course. • No Network. 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. Track your position in real-time and later view your track history. • Fully indexed point of interest (POI) database including weather, aids to navigation (markers and lights), obstructions, tides, currents, your buddies, and more.

◦ Radar mode Aisea App's Radar mode displays the movement of vessels in the vicinity equipped with AIS or using the App on a scalable chart. When it detects a risk of collision, the App will warn you minutes ahead. Aisea brings you peace of mind on the sea. ◦ Map editor and reporting tool Users can report dangerous floating objects from Aisea App, and Map Editors with business accounts can set various areas that require the nearby sailors' attention. Those reported markers may be public and visible on the chart for others or private and hidden. ◦ Voyage playback Playback the past voyages on the web anytime with videos and other voyage data since Aisea automatically saves them as your vessels navigate. These playbacks help investigate in case of accidents and are useful for optimizing navigation courses. ◦ Fleet management The Fleet Management interface is available for affordable Business accounts, letting you keep tabs on your fleet, clues, operators, and anyone you need to communicate for your everyday tasks. You and your operators can access the interface from your PC, smart device from anywhere anytime. ◦ Vessel tracking Aisea monitors vessel locations through Aisea App and AIS stations on the shore and ships. Vessels will be appropriately represented by vessel-shaped icons in scale rather than dots or triangles so that you can grasp the situation intuitively. ◦ In App Push-To-Talk Communicate with nearby users without radio equipment. UX is carefully designed to resemble the Marine VHF radio with plenty of guidance, so the learning curve will be shallow for everyone. Business users can talk within their business or projects.
