UTERNavionics is a navigation chart, and a very good one. It shows you the bottom in detail, but it won't tell you which fish are on that bottom this month, or which tide and wind will make them feed. Fish Scouter is built for that part: it scores every species for the spot you're on, shows charted public structure as fishing spots, and exports your marks as GPX that Navionics and the major plotters read. Most boat anglers are best served by using both. Here's who needs which, as of November 2026.
What Navionics is, and what it costs
Navionics Boating is Garmin's chart app. Its App Store listing describes nautical charts you can use offline, SonarChart HD bathymetry with 1-foot (0.5 m) bottom contours, relief shading, NOAA government charts, daily chart updates, dock-to-dock Auto Guidance+ routing, weather, tides and currents, Community Edits and ActiveCaptain, plotter sync, and GPX import and export. With a compatible sonar and plotter, SonarChart Live builds your own contour map as you drive.
The app is free to download with a free trial. After that, charts and advanced features need a yearly auto-renewing subscription. On the US App Store the US & Canada subscription is $49.99 a year as of November 2026, and the other regions are priced separately (for example Mexico, Caribbean to Brazil at $49.99).
What Navionics is great at for fishing
- Reading the bottom. One-foot contours and relief shading show humps, drop-offs, channel edges and holes that don't show on a satellite photo. For finding new structure, nothing on a phone beats it.
- Getting there and back. Routing, depth shading for your draft and shallow-water highlighting keep the boat off the bar. Fish Scouter doesn't do any of this, and it's marked not for navigation.
- Your plotter. Navionics syncs routes and markers with Garmin plotters and can renew your chartplotter card.
- Coverage. Navionics sells charts for many regions of the world. Fish Scouter covers US waters only.
What Navionics doesn't tell you
A chart answers "where is the structure?" A day on the water also needs answers to these:
- What's biting here right now? Is it gag on the ledge or mangrove snapper on the wreck? Navionics has no species forecast.
- When? Which tide stage, which hour of low light, which day of the week the wind lies down?
- Which spots are fish spots? A contour line is not a reef. Navionics shows charted features, but it doesn't pull in state artificial reef deployments, fish attractors, fishing piers or shore access as fishing spots, or tell you which fish each one holds this month.
- Can I fish it from where I am? If you're on foot or in a kayak, a chart won't sort spots by what you can reach.
How Fish Scouter fills that gap
A forecast for the spot
Fish Scouter scores every species in the water you're on from 0 to 100, this hour, with the reasons: the season stage, the water temperature from the nearest reporting sensor, the NOAA tide stage and the next turn, low light, the pressure trend, wind and the solunar periods. Tap a spot and it shows the fish that spot's kind of structure holds this month, the season stage of each one, and whether the next seven days suit it.
Structure as fishing spots
The map carries every charted wreck, obstruction and rock from NOAA's electronic navigational charts, state artificial reefs and fish attractors, ledges and hard bottom, plus the inshore and shore side: piers, fishable bridges, jetties, seawalls, beach access, beach cuts, boat ramps, marinas and kayak launches. That's tens of thousands of spots across every US coast, on satellite, chart or street maps, with NOAA bathymetry depth shading and contours.
Wind against the bank, seas outside
The outlook (three days on Angler, seven on Captain and Guide) scores each day for wind, gusts, seas, rain and the barometer, and scores each spot by its exposure. An offshore reef is judged on the seas, a mangrove bank on the wind against the way that shoreline faces, and in Florida's bays on the wind chop worked out from fetch and depth. Tell the app what you fish from (shore, wade, kayak, jet ski, flats skiff, bay boat or offshore boat) and it checks which spots and days suit it.
Season calendars
Every species, every water, month by month. For example, the Panhandle or redfish in Tampa Bay, readable without an account.
The handoff: GPX from Fish Scouter into Navionics
This is where the two apps fit together. Fish Scouter reads GPX files (Navionics exports markers as GPX), so you can bring your existing marks in on any plan. On Captain and Guide, Fish Scouter exports your saved spots, including any public reefs and wrecks you've saved, as a standard GPX 1.1 waypoint file. Import it into Navionics Boating, or load it onto a Garmin, Lowrance, Simrad or Humminbird plotter, and run to the marks on the chart. Coordinates are also shown in degrees-minutes for typing straight into a plotter.
- Find the spots in Fish Scouter: filter to Structure, check the seven-day outlook for a calm day, and save the reefs and wrecks the forecast likes.
- My spots → Export GPX.
- Import the file into Navionics or your plotter.
- Navigate on the chart. Fish on the forecast.

Who needs which
- Offshore and big-bay boaters: both. Navionics to run the boat safely and read the contours; Fish Scouter to pick the day, the structure and the species, then GPX the marks across.
- Flats and backcountry skiffs: both helps. Navionics for the channels and shallow-water shading; Fish Scouter for the tide window, which bank the wind leaves flat, and what's on the flat this month.
- Shore, pier, bridge and wade anglers: Fish Scouter. You don't need a nautical chart to walk a seawall, and Fish Scouter's Shore and Wade filters show the spots you can reach on foot.
- Kayak anglers: Fish Scouter first, for launches, wind and the spots within paddling range. Add Navionics if you paddle open water and want the contours.
- Anglers outside the US: Navionics. Fish Scouter only covers US waters.
Whatever you keep, check the current rules with your state agency first, such as Florida FWC. Seasons and limits change. If you're still deciding on a map, our guide to the best app to find fishing spots walks through every approach.
Our verdict
For navigating, Navionics wins, and Fish Scouter doesn't compete there. For finding fish, we think Fish Scouter is the better app: it tells you which species are on which structure this month, which tide and which day to fish it, and it puts reefs, wrecks, attractors and shore spots on the map as fishing spots. Then it hands the marks to Navionics as GPX. Boaters should run both. Shore and kayak anglers only need Fish Scouter.
