You may have a dual transducer Finders "search Fish> split screen and allow the screen to display images from both transducers simultaneously. Another application is to have a split screen database window in the middle of the screen. A window can display data of digital information such as speed, depth, water temperature or length and latitude. The other half of the screen can display graphics that are common objects in the water.

Grayline ®, white or Bottom Hardness

More fish finder shows the bottom are shown by a thin line with a variable width band underneath. This section of the screen allows see the objectives in the bottom and also indicates bottom hardness. An experienced fisherman will often be able to differentiate between the mud, sand and rocky bottoms.
