learning to use the sonar...

[reelfast]

those are some nice lakers. The sonar side of the unit as well as most units do will track fish on the way up. They guys I ice fish run the sonar and when a fish comes in its like a fire drill to work the jigs. They show as a solid line on the screen just like in the video on u tube. Side imaging is like a scanner. As you move across an area it uses a narrow band of sonar to scan about 150 feet out each side and creates an image on the screen as it scans. If you stop or go faster than it can proccess the image becomes distorted. the hummingbird web site has a pretty good explanation of how it works.
