Sonar Operations
As you can see from the quick reference on the previous page, basic operation is pretty easy, right out of the box. If you are a sonar novice, try operating the unit with the factory defaults until you get a feel for it.
As you are learning the basics, there is one setting you might want to tinker with from time to time — Sensitivity.
Sensitivity controls the unit's ability to pick up echoes. If you want to see more detail, try increasing the sensitivity. There are times when too much clutter appears on the screen. Decreasing sensitivity will re- duce the clutter and show the strongest fish echoes — if fish are pre- sent. As you change the sensitivity setting, you can see the difference on the chart as it scrolls.
