We're from Northern Australia and the fish species we use in the demo are as well. But our concepts work worldwide! We've had happy students in 28+ countries. This goes to show you that fish targets are fish targets and our concepts work wherever you are in the world.
We have also included some deeper water stuff for the offshore anglers using only 2D traditional. It is especially important you bed these concepts into your mind and really put them into practice as depth exacerbates the problems we have seeing fish and identifying large fish vs small fish.
Understanding these concepts really is the difference between the marketing hype and the reality of what you see in your boat.
