The boat i bought came with 2 7612's and all i can say after the first time out is wow. Im highly impressed. Granted the graphs were already set up and im not an electronics guru by any means but they were impressive. I had L's in my last boat and my buddy that was with me has L's and even he was impressed. The SI was gin clear, the sonar was perfect and the 1' contours were great although its going to take me some getting used to as to how to set on stuff. The DI was a bit lacking but i can deal with that. Came with a nib panoptics ducer that i may or may not install. These units quickly went from something i was skeptical of (had never been in a boat with them) to something im sure im going to love
