How and where is your transducer mounted? I have a Helix 9 Gen2 that has 2D and GPS only that I had all sorts of problems with and discovered that the shoot through transducer in the bilge was not installed correctly.

Below the live well pump bracket, in the area specified for a transducer on a pontoon boat. On the center of the left pontoon. And it's been leveled to position at searching speed (3.5 to 4 mph)
