I haven’t had the least bit of trouble with my pole made from pvc. I also have the IMS perspective mode mount that Iasacc sales on bass boat central. I did put a bench mount bicycle repair stand on the deck to hold the pvc pole & if you don’t over do the tightnesses it can move back away from a standing tree that you may not see under the water. I like it myself. However a person could make a pole out of aluminium tubing with something to hold an aluminum shaft running down through the center that would let it turn whatever direction you wanted to view. I’d be afraid if it didn’t give like mine does that it would break the transducer bracket if you hit a submerged tree. They do make some nice pole mounts that may suit you better than a diy mount.
