I came across a fish finder basics video on YouTube and thought it would be cool to share it. The video is 17 minutes long and explains how side imaging works at a real basic level. You know, something even I could understand. Definitely take the time and watch this video if you are considering a side imaging unit. I also recommend subscribing to the Fish The Moment Youtube channel as he has some very cool videos on imaging and some cool fishing videos.
