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.\n\n\nKey Features:\n\n\n• 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.\n\n• 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.\n\n• 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.\n\n• 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.\n\n• 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.\n\n• 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.\n\n• Record your tracks. Track your position in real-time and later view your track history.\n\n• Fully indexed point of interest (POI) database including weather, aids to navigation (markers and lights), obstructions, tides, currents, your buddies, and more.\n\n\nWebsite: www.miratrex.com\n\n\n--------------------\n\n\nPlans:\n\nBase app with limited features - Free \n14 day trial of all premium features - Free\nAll premium features (Monthly) - $2.99\nAll premium features (Annual) - $29.99 (Save 16%, about 2 months free)\n\n\n\n-Payment will be charged to your iTunes Account at confirmation of purchase.\n\n-Your subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current subscription period.\n\n-You will be charged for renewal within 24 hours prior to the end of the current period, for the same duration and at the current subscription rate for that product.\n\n-You can manage your subscriptions and turn off auto-renewal by going to your Account Settings in the Apple Settings app after purchase.\n\n-No cancellation of the current subscription is allowed during active subscription period.
