I run the Lowrance 83/200 and a P66. I would say that I'm getting a crisper image with the P66. You have to order specifically for a Lowrance and it comes with the blue connector. If you go that way don'forget to change the transducer choice in the menu installation. You got 2 choices for the 66 pick the P66/5000 the 2nd choice is 10,000 and I think with thac one you are missing the surface temp.
