Data-backed Forecasts. Powered by ROFFS®.

FishCast® uses the same oceanographic intelligence trusted by tournament pros—including the more important target fish species habitat parameters such as water temps, ocean clarity, currents, frontal boundaries, bottom structure, ROFFS® historical hot spot data and more.

That data is then analyzed by cutting edge data analytics and turned into forecasts that decreases the uncertainty by producing an optimal catch location map. Instead of wasting hours chasing dockside rumors or old reports, you can head straight to the most promising water conditions, saving time, fuel, and frustration while fishing with the same confidence as the pros.

Planned with precision.
3-hour forecasts, updated daily.

Fish are always on the move. FishCast® keeps you one step ahead with forecasts you can scroll through hour by hour, day by day. Each daily forecast includes 3-hour windows so you know when and where conditions—and fish—will be at their best. That means less waiting, less guessing, and more casting when it counts. With FishCast®, you’re always fishing at the right place, at the right time.

Predicted top fishing hotspots.
Simple C-MAP® chart overlay.

Smart overlays. Instant clarity. When you’re on the water, you don’t need complex data, you need answers. FishCast® delivers a ranked list of the top local fishing hotspots, clearly prioritized by probability of success. Define your own search area, up to 120 NM from your home port, and FishCast® does the work of narrowing it down for you.

As a simple overlay on your C-MAP® X chart, forecasts can be toggled on or off in a single press. The result? Smarter decisions in seconds, and more time with your line in the water.

Seamless integration.

Exclusive to C-MAP® and Simrad® marine electronics.
