The app is a free download on the App store. The free version allows you to create waypoints, see other users, display points of interest, and see your current position on street and satellite maps. In order to display nautical chart data and access PRO CHARTS™’ advanced navigational features, you will need to purchase a subscription for $29.99 per year or $2.99 per month. A subscription includes continuous updates to all chart data plus new features and enhancements to PRO CHARTS™ throughout the year. We have a long list of enhancements in the works and we are confident you will find them to be well worth the cost of the subscription.
iPhone 3 or later, iPad 2 or later, iPad Mini.
iOS 7 or later.
If your iPad is WIFI only, you will need an external GPS to navigate with PRO CHARTS™. We recommend the Dual XGPS150 http://gps.dualav.com/explore-by-lifestyle/marine/xgps150-for-chart-plotter-apps/, but there are also others on the market that will work. NOTE: iOS version 8.3 has compatibility issues with some Bluetooth external GPS devices. Be sure to check with the manufacturer before purchasing.
No, PRO CHARTS™ has a sync capability so you can easily synchronize your data between all devices. To do this, touch Sync Waypoints under the Account menu on the iOS device storing your waypoints. Select Upload Waypoints to upload your waypoints to your account on the MiraTrex server. Next, touch Sync Waypoints under the Account menu on another iOS device and then select Download Waypoints. This will add the downloaded waypoints to any that already exist on your device.
See Waypoint Import Steps here.
Sometimes the internal compass needs to be recalibrated on an iOS device. Exit PRO CHARTS™ and open the Compass app. Roll your device around as needed to recalibrate the compass. For more information, see https://support.apple.com/en-us/HT203301.
Displaying too many Points of Interest at the same time can affect performance, particularly on older devices with slower processors. If PRO CHARTS™ seems to be running slow, you may want to turn some of them off. If that doesn’t help, completely close the app by double-clicking the home button and swiping up on PRO CHARTS™ then re-launch it.
Be sure you are entering the latitude and longitude in the correct coordinate format. PRO CHARTS™ can accept the following formats: Decimal (e.g. 27.929360, -82.521973), Minutes (e.g. N 27⁰ 55.760’ W 83⁰ 31.320’), or Minutes/Seconds (e.g. N 27⁰ 55’ 46” W 83⁰ 31’ 19”). Verify the format of the waypoints you want to enter then set the Coordinate Format in the General Settings.
Yes, you must have a 3G or 4G iOS device and you must be online with an internet connection through cellular service in order to see other users or be seen by others.
NOAA continuously updates the data displayed on their U.S. territorial water charts and they distribute the changes to developers every seven days. Our servers automatically receive and process these changes so that the latest charts are continuously available to the PRO CHARTS™ app whenever you are connected to WIFI. This means that any chart data you are viewing while connected to WIFI is no more than seven days old.
This is because you have not downloaded the chart data for that area in advance. Whenever you are connected to WIFI, PRO CHARTS™ automatically displays both overlay and base map chart data even in areas you have not yet downloaded. However, this chart data is only cached temporarily into the iPad’s memory so it may not be available later when you are out on water without a WIFI connection. This is why it is important to download the charts you will need before heading out. To do this, pan and zoom the chart to display the area you wish to download. Keep in mind, NOAA chart files are very large so it’s best to start with a small area (less than 200 square miles) to minimize the time it takes to download. With the desired area displayed on screen, touch the menu button and select Chart again. From the Chart menu, select Download Charts to begin downloading. The chart data for the downloaded area will now be available at all times even when you do not have an internet connection.
Yes, a PRO CHARTS™ subscription covers all devices on your Apple account. When you purchase a subscription, you will create a user account. Just log in with the same user account information on your other devices and you will not have to re-purchase.
We highly recommend using a LifeProof case to protect your device. www.lifeproof.com
Drag the Overlay Opacity slider all the way to the right so that the overlaying chart is displayed at its brightest. An anti-glare screen on your iPad is also highly recommended to reduce glare.
The high-resolution NOAA charts in the app cover U.S. territorial waters only, but all the functionality in PRO CHARTS works regardless of your location. You may want to try the Global selection as your Chart Overlay or you can just leave it set as None and navigate using the satellite, road, or hybrid base maps. Just be aware that the Global charts are high-level only and do not show depths.
Only the NOAA (RNC) and NOAA (ENC) charts can be downloaded using the “Download Charts” button in the Chart menu. If you have a different chart set selected as your Chart Overlay, you will see this message if you select “Download Charts”. The other chart sets, like Mexico and Brazil, get automatically downloaded as you view them. To make sure you get all levels of these charts, be sure to scroll around and zoom in and out while connected to WiFi. As long as you’ve viewed them in advance, they will be available later when you do not have a data connection.
For the NOAA (RNC) or NOAA (RNC) nautical charts to appear: 1) you must be located in a coastal U.S. area covered by NOAA, 2) you must select NOAA (RNC) or NOAA (RNC) as your Chart Overlay in the Chart menu, 3) you must have a WiFi connection or a strong cellular connection, and 4) you must download the charts in advance while connected to WiFi for them to be available later when you do not have a cellular connection. The way PRO CHARTS works is that you select the type of charts you want to be displayed as an overlay over the top of the base maps. If you have the Chart Overlay set to None, only the standard Apple road, satellite, or hybrid base maps will appear. In an area where there are no overlay charts available, like outside the U.S., only the base maps will appear. However, all the standard navigational features like creating waypoints and navigating routes still work regardless of which chart set you choose or even if you have none selected.
This feature is specifically intended for situations when cellular connectivity is weak. The way PRO CHARTS works is it tries to download new chart data whenever you pan the screen to a new area. If you have no cellular connection at all, it doesn’t make the attempt, but if you’re in a spotty area, it can cause performance issues. If it sees a cellular connection, it still tries to download new charts tiles, but it can take a LONG time and make it seem like the screen is locked up (killing the app cancels the download request) if your cellular connection is weak. We added the Display Downloaded Charts Only feature so PRO CHARTS will only display chart tiles you’ve downloaded in advance and doesn’t attempt to download them on the fly. This dramatically improves performance as long as you’ve downloaded your charts in advance. If you’re offshore or in an area of weak cellular service and notice PRO CHARTS is running slow, try using the option. Just be sure to remember to turn it off when you get back home.
Heading and position are determined by your iOS device, not PRO CHARTS itself. When your heading setting in the General menu is set to “True North”, PRO CHARTS uses the internal magnetic compass to determine your heading. However, the internal compass is affected by metal objects and magnetic interference. For example, it can be off by as much as 30 degrees in a car. To make it more accurate, you can change the setting so that heading is determined by GPS movement instead of the internal compass in the General settings menu. The downside of using GPS to determine heading is that movement is required. If you stop and the internal GPS cannot detect movement, the boat icon direction and compass heading indication will not be reliable.
