I'm going to ask the question of how good is your boat control? With the qualifier of I've never fished with Livescope, it seems to me you'd better have a pretty steady platform to keep if focused on where you want to look. As in a good trolling motor with some sort of spot lock that works. I don't, and that's why I have no interest in the live stuff from either HB or Garmin. The side imaging works great for me in finding fish and structure but I really can't stay on a given spot well enough to put the live action stuff to good use. A lot of the video's on YT show the user making constant adjustments with the livescope, seemingly to get it pointed just so.
Yes, I was talking to myself; sometimes even I have to ask for expert advice.
