I bought one of these(Da Ducer.) did not like it. too clunky. hard to deploy. bolts broke. put a one inch pvc pipe on an old motor guide trolling motor bracket with gas assist cylinders. easy in. easy out. can turn pvc pipe to any direction (poor mans 360). I think "Canepole" used something like this at one time. i liked the fact that i do not have side image on a trolling motor motor(turns too much) and there is no electrical interference when mounted away from electronics and trolling motor. plus is motor guide trooling motor bracket has a breakaway spring systen and pvc gives also.
(no breabing transducer). i broke a transducer on (Da ducer)
