Deeper sonar pro plus Basically new. I've used it maybe 4 or 5 times. Very well in depth sonar will tell you everything a traditional fish finder will tell you. You may cast it out or set it along side your boat for a boat fish finder. Also it runs off a app on your phone so when it hits the water it's already communicating with your phone. It automatically turns off when it comes out the water. Last a very long time on a single charge. It's $249 brand new so my loss your gain. I also will show you how it works on your phone when you buy it.
