Overhead CastAccurate Fly Casting Dynamics

Physics-based models allow the rod and line to accurately simulate real world casting. Effects of wind, water, current, gravity, air resistance, and rod motion are all integrated into the calculations resulting in casting so realistic it can be used as a training tool.

Roll CastLearn Fly Fishing Techniques

Practice different fly fishing techniques including overhead casting, roll casting, side casting, shooting line, and mending. Learn to cast in different wind conditions, when to shoot line for maximum distance, and how current affects mending.

DestinationsNine Unique US Destinations

FlySim includes nine scenic US destinations from Oregon to Maine. Some destinations are unlocked as you complete the goals.

FishTen Different Species of Fish

Ten unique 3D fish models, including rainbow, brown, brook, cutthroat, and golden trout. Fish are stored in your daily and complete logs, along with information such as length, weight, tippet, and fly.

FishingIntelligent Fish Behavior

The fish swim, feed, strike, and fight just like their real counterparts. A sophisticated strike engine determines when the fish will strike based on many factors including the fish's vision cone, fly selection, fly presentation, and fish spook factor.

WaterWater Modeling

3D water modeling includes current, stream beds, rocks, and rapids that vary from one destination to another. Look for fish near the rocks and rapids as you would in your favorite fishing destination.


You start each day with 25 different flies including dry flies, nymphs, and attractors. 6 Tippet sizes and 3 weight choices will help you optimize your setup for a trophy catch.
