I fished with my 7 for the first time this week. The 2d sonar view was pretty awesome, I could get a much better feel for how many were actually down there. I will be mainly using that for sure. I will say the flasher mode was impressive too, I wasn't sure what exactly to expect with an LCD unit in flasher mode. So for guys who's comfort zone is looking at a flasher the unit does that really well too and with split screen you can gain confidence in both. Having a Lakemaster map chip/GPS makes a huge difference in the waters I fish and took a lot of guesswork out of where to start punching holes. Definitely going to hang onto my ICE 45 as a back up, but I am really excited about the capabilities of this unit. I didn't get a chance to mess around with settings much but I was a big fan of bumping up my chart speed all the way up to ultra on 2d sonar.
