I've got a Helix 9 gen1 at the bow and a new 10 gen2 at the console, and the Mega Imaging is a huge difference in clarity in DI, SI, and 2D sonar with the chirp. The reason I went with a gen1 at the bow was because I'm wanting to use it strictly for 360 imaging. The Mega Imaging just doesn't seem to be that useful at the bow IMO, but is worth the money at the console, because that is where you spend most of the time graphing and marking waypoints.
