CB I am definitely loving it. Just having so much experience on the water has helped me dive into it pretty easily.
That F&D is a nice boat...plenty of room, plenty of stability and plenty of storage. I ALMOST bought one but after Saturday glad I didn't. My Redfish will SMOKE it with half the effort.
I am powering the fish finder with a small motorcycle battery.
However, most of the guys in my club use the small rechargeable 9.6V RC car batterys. Easy to recharge and last all day with no problems. I will eventually go to that but I had the motorcycle battery anyways. They don't require 12v to run though because the 9.6 runs em fine. I forgot to charge mine and it read 7.5V most of the day....never missed a beat.
