Humminbird Helix 7

[Bad Habit]

Mounted a new Humminbird helix 7. Seems to work fine trolling but when up on plane the depth goes crazy. I mounted the transducer according to the instructions provided. It might be tilted a little back slightly. I thought this would be better than forward to read rigger balls if not exactly parallel with the water line. (Hard to distinguish on the trailer) Could it be air bubbles and turbulence when running faster? Any thoughts would be appreciated. Rick

Probably not mounted deep enough in the water. What kind of boat?

Yup this or too much disturbance in the water when running.
