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.

Great idea, poor execution.

As mentioned before, this is a really great idea, but poorly implemented. I used it today and it would lock up every time I took a screen capture. Also, there is no auto-rotate feature, so you are stuck in landscape mode, but only in one orientation. Also, when connected to your unit via WiFi, you loose the ability to use cellular data. This means you have to constantly disconnect and reconnect from the unit. Tested on an iPhone XS using both a Lowrance Elite 7Ti and HDS 9 Live. It’s better than taking pictures of the screen, but just barely. If they can work out the bugs, this will be a really useful application.

Works great for me

I’ve been using the Link app on my iPhone to serve as a remote display and control for my Simrad NSS9 Evo 3 unit with FMT tracks for over a year now. The clarity of the satellite image is equal to that showing on the unit, and all the control functions do work. However there is some lag in the screen updates that would prohibit trying to use only the app at a second helm. But for my slow speed use while fishing away from the helm it’s just fine.

As some have noted the WiFi connection to the unit does result in a non working internet connection error on a cell phone, but considering there typically isn’t a cell signal where I’m fishing it’s really not a problem.

Based on the success of my using the app on my iPhone I’m going to start using it on my iPad so I don’t have to zoom in/out as much. Mounting is simply a GoPro adhesive camera mount stuck on the back of an Otterbox case that I put on my GoPro claw mount. EzPz.


Major bug with iPhone 8plus

Although the app seems to be a great idea,the actual works are flawed. First things first which is a big one. When connected to the app via WiFi you loose internet service on a mobile device with data ( iPhone ) there seems to be no way to manually connect the Lowrance unit without using the automatic mode which in turn adds dns info which prevents from using LTE while connected to the Lowrance unit. Dumb. Should be able to have mobile data work when connected to unit. Also does not rotate on an IPhone 8+. Can only use the phone one way. Again, dumb. This app would be pretty nice when these two things get fixed. Until then it’s pretty crappy.
