The Link app gives you remote control of wirelessly connected Simrad, Lowrance, or B&G multifunction displays from your smartphone or tablet. Link lets you select any wirelessly connected display on board, duplicates the screen in real-time on your mobile device, and puts control of most display functions at your fingertips.

Work with charts, sonar, and radar, control your on-board entertainment system, view data from connected engines and instruments, and much more. With Link, you’re constantly connected to your boat’s key systems from anywhere on board – making it easier to plan trips, fish, sail, handle maintenance, and otherwise make the best of your time on the water.

Link also gives you the ability to wirelessly back up and restore waypoints, routes, tracks, and display settings directly to your mobile device. This makes it easier than ever to protect your valuable boating data against loss or theft, and to keep your backups up-to-date with zero hassle.

The Link app is compatible with Simrad NSS evo3, NSS evo2, NSO evo2, NSS7/8/12*, and GO series displays; Lowrance HDS Carbon, HDS Gen3, HDS Gen2 Touch*, HDS Gen2**, and Elite Ti fishfinder/chartplotters; and B&G Zeus³, Zeus², Zeus Touch*, and Vulcan sailing chartplotters. Displays without built-in wireless connectivity require an additional WIFI-1 module. To enable the Link app, a free software update may be required for your display.

Link works with the Apple iPhone 5s and later devices running iOS 9 or above.

* Mirroring only. ** View only.

Just ok

Does what it says on the tin - but isn’t a great experience.

With a little thought and imagination it could be so much better - allowing things that are frankly too difficult to use on the touchscreen - like easy upload of waypoints and routes

Full screen problems - Fixed

Update Jan21 - the full screen problems are now fixed. Haven’t had the opportunity to use in anger, but is looking good.

As mentioned by other reviewers, the app does not show in a full screen landscape mode. The mirroring and control does work, but the small window makes it of little use.

Developer Response ,

The app is now fixed. Also the new B&G app offer Mirror and Control features.

Enable rotation and use the device screen size

This app could be great but it isn’t right now.
I’ll happily update my review if better updates are pushed.
The main thing is the remote control. I have an iPhone X and an iPad Pro 12,9”. On both it is ridiculously small and you cannot even have it rotate to make full use the empty screen space.
Simply change the modal presentation style of the remote control to a real fullscreen and enable rotation for that screen.
The real app does not even match the screenshots on the AppStore.
