Garmin sonar colors
The waves make it difficult for me to get a clear picture of the bottom so I'm hoping to use the colors to better identify the bottom. I understand that a very dark skinny line mean's rock bottom but I hope to get a little better understanding how the fish finder works. Neil |

Gradual change from color to color typically means less-dense bottom. Think sand, grass/vegetation. Quick changes in color (like you describe as skinny lines) typically mean dense bottom. Hard pack, rock, or concrete/asphalt (seen mostly in freshwater, obviously.) The best way to learn your unit is to use your unit. The best education is time on the water...... |
