Looking to the Forum Brain Trust for some feedback. On my last boat I could never get the Helix XHS 9 HDSI 180 T transducer to read depth when on plane so I had to add the 2nd 2D sonar skimmer transducer and Y cable to compensate. On my new boat I am trying again to get the XHS 9 HDSI 180 T to read depth accurately at high speed. The new boat has a much smoother hull bottom and so far I have gotten very promising results with crystal clear SI/DI readings up to 8mph before having to get the boat up to speed and get on plane. Even on plane I have gotten great readings up to about 32 mph. After 32mph the depth readings get erratic.
1. What is the highest speed (greater than 32 mph) that you have gotten your XHS 9 HDSI 180 T to consistently read depth?
2. Is there any danger of destroying this expensive transducer by consistently operating it at higher speeds say >45mph?
