Six Ways to Customize Displays

Expert tricks to help you set up your chart plotter, fish finder and radar screens

Setup Problem #4
Slow scrolling speeds on your fish finder.
Why is it that most fish finders come out of the box set to medium scroll? I've been on boats with knowledgeable captains only to hear that the one complaint they have about their fish finder is the slow scroll speed - until I started pressing buttons and changed it for them. A slow scroll speed reduces detail level and can cause multiple targets to "stack" and appear as a single target. It's no different than the number of frames per second in a video: The more there are, the better the picture will be. In fact, the only reason ever to slow down scroll speed is to maintain a visible history on screen for a longer time period. But if you didn't notice a baitball or drop-off before it passed across the screen, you must not be paying much attention in the first place.

The Fix
Set the speed as high as it'll go. All fish finders come with this necessary adjustment; you just have to figure out where it's buried.
