Yep, I just hooked up my new 93sv on Sunday. Maybe I'll pick up the new Plus for the console and move that one up front. As long as the new Echomap Plus units and Echomap Chirps can be networked, which I would assume is possible.
Only issue with that is Garmin mentioned the new units have sonar sharing across units. If that requires a different connection than the User Data cable, maybe the new and old ones can't be networked.
Either way, I love my Garmin so far. Blows my buddies Elite 9TI out of the water when it comes to imaging and the quick draw is incredible. Much better than the insight genesis map I was using on my old Lowrance Hook 7.
