This is my mast so far. The Axion head attaches to the ram ball. I’ve yet to fab a transducer mount. The arms straddle the hole and the center pole rotates while arms are stationary on the ice. The transducer cable runs up the inside of the pole.
So it’s been a year… but I’m thinking about trying this since it’s impossible to find a Helix ice transducer right now. How did it work for you? Any advice?
