There Fish – How To Use The Navionics Web App – Maps


Where fish? There fish!

We’d like to take you on a little excursion to the world beneath the waves of your local fishing hole with the Navionics app. We’ll make a web-based map and show you how to get a bead on the best hotspots, even without a depth finder or fish finder.

Imagine that you’re aboard your boat and underway on your favorite lake. The fish finder is doing its thing. You’re looking for fish and hotspots. It likely won’t take more than an hour for you to get tired of scrutinizing the little icons on the display and casting purely on the off-chance that the big one down there is in a biting mood. It would be more effective to know in advance where you should be looking to find the best hotspots. Once you’ve arrived at an established hotspot, you can use your fishing time to the fullest and simply concentrate on the fish. Here, you’ll learn how you can use the Navionics app and your smartphone to find the best fishing spots on your body of water – and get a big advantage over the other anglers in your area.


The Navionics app: Boating

Your smartphone knows where you are, and it’s easy to give the Navionics app access to your location data. The app will show you in exactly which depth contour you and your boat are situated. It will also display your current speed. To record the best spots, you can use the Navionics app to place and save markers – you’ll be able to pull up your favorite fishing spots whenever you want.

The Navionics app is available for iOS and Android phones – you can even test it for a week, absolutely free. You simply have to download and install the Navionics app on your smartphone.

Choosing the right Navionics maps

It’s important to choose the right map for your situation. The Navionics app has a map for northern Germany and northern Europe (including Denmark, the Baltic Sea and southern Norway) called Skagerrak & Kattegat. 

If you’re in southern Germany, you’ll want to go with the central & western Europe map. This option covers France, Austria, Switzerland, northern Italy, and all the way down to Spain.

Navionics map pricing

In our own copy of the Navionics app (iOS), we use the central & western Europe map – we pay €27.99 per year for the privilege. The  Skagerrak & Kattegat map would cost €33.99 per year. If you compare this with the cost of the depth finder-specific Navionics Plus maps, you’ll see what a steal this is. We had to shell out €199 for our Raymarine Dragonfly Pro 5.

What advantages does the Navionics app offer?

In most cases, you’ll have your smartphone with you on a fishing trip, anyway. We took the extra precaution of buying a waterproof case for our iPhone. You can display your current position and route on the Navionics app map, and we use our depth finder for sonar and the DownVision display. We didn’t want to part with €1,500 to pick up a giant display – having 3 smaller ones gives us plenty of flexibility, anyway.

Why the Navionics app is so good

  1. You can plan your fishing trip easily, whether you’re currently on the water or not
  2. With the Navionics app, you always have the best maps on hand while on vacation
  3. If you have a Lowrance, Garmin or Raymarine depth finder, you can sync their SonarCharts with your smartphone
  4. It supports the SonarCharts display!

The Navionics app for the iPad

Of course, it’s much more comfortable to use a large display like those found on the iPad or an Android tablet – you can zoom in further and display even more detail. The Navionics app for tablets is worth your while if you have a waterproof case and a SIM slot, which you’ll need in order to use the app’s GPS functionality. The large-format, high-definition imaging on a tablet makes using the app a pleasure in its own right.

Can you use the Navionics app in conjunction with other manufacturers’ depth finders?

The short answer is yes. Manufacturers like Raymarine, Lowrance and Garmin offer Wi-Fi transfer to external devices (smartphones and tablets) with some of their models. For example, we regularly use the Dragonfly Raymarine 5 Pro and transfer its SonarCharts to our iPhone. Pretty neat!

The Navionics web app

The Navionics web app gives you the option of planning your trip from the comfort of your own home using your computer or tablet. You can view depth contours and quickly identify hotspots – it’s a whole new way to familiarize yourself with your local body of water. Go ahead and give the Navionics web app a try – you might just find inspiration for next spring.

Making the most of the Navionics web app

On the right side of the screen, you can zoom in and out of the details of your Navionics web app map. At the bottom right, you can set your distance scale to nautical miles or kilometers. The most important on-screen icon is the SonarCharts symbol in the bottom left corner. You’ll find that the overlay setting is useless on the water – anglers can pretty much ignore it. The Navionics web app should display just fine in any available browser.

How can you use the Navionics web app?

The app is a great way to get to know your local body of water and plan your next fishing trip. It’s also good for scouting new bodies of water before you go on vacation; you don’t have to waste needless time looking around once you get there – you can simply focus on fishing. If you’re already on the water, you won’t get far without the Navionics app for your smartphone or tablet. The web app can tell you where the hotspots are, but it’s definitely better to have the GPS functionality of your smartphone if you want to squeeze out those last few meters to the best locations.

What does the Navionics web app cost?

Nothing at all – the web app is absolutely free. Thanks, Navionics!

How to interpret map details in the Navionics web app

The map includes all water-related details that anglers need – the most important being the given body of water’s depth contours. Using this info, you can locate drop-offs and underwater hills (a fish favorite). Especially on larger bodies of water – like our local Müritz – there are plenty of good spots, but even more that are pretty much fish-free. Fish like to hang around abundant sources of food, which is exactly what the Navionics maps can show you (in both the web-based and smartphone apps).

Navionics offers useful online seminars in which depth finder pros show you how to use the maps and how to find the best fishing spots in summer and winter. Lowrance is a regular partner of the Navionics webinars. The seminars are held in the evening hours in the USA, which means you’ll have to wait until around 1:00am here in Germany. It can be a bit of a pain to stay up that late, but we believe it’s a good investment of your time. The presentations are in English, but there are online slides which you can screenshot and translate after the fact.


You can usually find the webinars on Navionic’s Youtube channel. You’ll find a list of the webinars here:
