Take the Guesswork Out of Finding Fish

Built By Fishermen For Fishermen

SatFish is not just another Sea Surface Temperature chart that you could get for free.

By joining SatFish you are tapping into high-tech software built by fishermen for fishermen to process all of the most important layers of data collected from satellites as they scan the earth. These layers are processed by a Ph.D. in marine science, painting you a real-life picture of your fishing grounds. SatFish is the most powerful tool online, helping you find more fish. Knowing which way to point your boat translates directly into more fishing time, saving a ton of money on fuel and putting more fish in your holds.

With live satellite imaging, wind, sea state, currents, and more, you can make those crucial decisions to keep your crew safe and make the most of your free time.

No more running blind looking for the edge of the Gulf Stream. Need to find that warm water eddy where your buddies caught fish a few days ago? Just find it and plot it with SatFish. Built-in plotting tools let you plan and print your route before you go. It’s a fact that bait and predatory gamefish gather along the edges and breaks that form between moving bodies of water offshore. Subtle differences in temperature, color, and clarity can be a magnet for fish. You can spend too much of your precious time and fuel running around scouting the old-fashioned way. SatFish gives you the high-tech advantage, in an easy-to-use proven package. SatFish can pay for itself in fuel savings in just one trip, and how do you put a price tag on catching more fish?
