I don't have FFS or any sort of "live view" stuff on my boat, yet. I definitely see the value in having more information regarding what's going on under the surface. I just hate mandatory "clutter". I create enough clutter on my own w/lures, rods, Plano-boxes, bait containers, etc, etc, etc.
I'll get it when it's fully integrated into the bow-mount or there's a way to deploy it off the transom that doesn't stick up above the motor like a power-pole.
