Okay I was in BP a few weeks ago looking at livescope and talking to the sales rep. I have two Helix 9s and Humminbird 360 on my boat. The guy told me I could use my Helix SI and DI to find the spots I want to fish that I didn't need that on the livescope. He said i could just get the livescope screen with the transducer that comes with it to see the fish without spending the $1500 on the other part. Is that correct or do you need the entire pkg? Thanks I'm not hi tech enough to know what to do.
