• The Garmin Fish finder is not only easy to use, its high-resolution display makes the information easy to see. The 240-by-240 pixel high-definition display gives you a clear picture of fish, thermoclines, structure and bottom surface. By using various shades of grey, the0000 Fish finder paints a beautiful picture, leaving little to interpretation. Operational features include a unique control bar that identifies the most commonly used fishing settings. So without hunting through complicated menus, you can quickly configure and save the settings you want. As lake conditions change, you can fine-tune your Fish finder on the fly.
