Ok, so I got some private messages about this unit I was using last time I posted a video. So I made this video since it has some of my commentary on the unit. This was my first day out using it, so I'm no pro with it yet. But at least you can see how it works a little better in this video. I kept getting interrupted by the fish. They just wouldn't stop biting.

Here is the Deeper Fishfinder Review video for those who were interested last video I posted.

What a great product do you find that the phone laying on the ice kills the battery quick?

It was pretty warm out and the battery actually did just find.  The sonar died before the phone,  I just turn down the device lighting.  In cold weather though like -15 and below the phones die really fast, so would only work well in a tent on those days.
