I've been messing with mine to try to install my Panoptix and no luck yet. I think the transducer is too heavy for the stow/deploy mechanism. I used a coiled hose and was able to get about 60% success stow/deploys but once in a while the cables would get caught underneath the unit.
What sort of hose? Im thinking that might could work. Maybe a bigger hose is better. I dont think my unit has any issues lift the HB transducer. Got any pictures? You could text me some at 254-542-1516
