Does anyone know what this is in the picture on the back of my Lowrance Hook2 7"?

Thanks, everyone, lots of good opinions. Especially having three units. My wife will love that one.

Just what I'm looking for, opinions and the reasons that go with them. That's what will help me make my decision. Thanks

I just received a Lowrance Hook 5 w/ down scanning for Christmas and I've decided to add a Lowrance Hook 7 w/ side scanning to go with it. My question is, where would you put the side scan? Bow or console? I'm thinking the bow so I can get the best image of the bottom while fishing. What do you think? Thanks
