One great thing about using a fish finder is that there’s always more to learn. You can start simple, with a display that shows just depth and fish icons.

Our detailed tutorial gives the basic skills you’ll need to identify fish and judge their size, locate different types of underwater features, and judge bottom type and hardness.
