I had the opportunity to run my boat with a Mega transducer (710268-1) connected on the port side and a Mega+ transducer (710292-1) on the starboard side. They go to a Y cable and then into my Solix G2. I only have a few minutes on the water but you can see the range difference. My understanding is that the difference would be even more significant connected to a regular Mega control head.
