I agree, I used to run my vex off the universal sonar, not too impressed with running a cable up the shaft, but I’m thinking it’ll be nice enough to have drifting, vertical jigging, etc that I’ll deal with it.
I bought the universal dual beam ducer, not the high speed. I already have a HDS in the counsel and I really don’t need two high speed units. They come with a kit that mounts to the trolling motors drive unit via a hose clamp.
Mine is out in the cold shed 50 yards away, but I found this picture online.
