If you looked at someone's boat with it installed you wouldn't be confused at all. It's pretty simple. The transducer and graph plug into the black box. The graph and the black box have a power cable that goes to a battery. That's it. Now, how you run the wires, mount the graph, and install the black box and transducer can be different on every boat. Bluball on here works at Performance Fishing Electronics. I'd send him a private message and discuss. He and his boss Danny can do the entire process from start to finish and are great guys to deal with.
