I installed my Humminbird 386CI DI combo through hull in my kayak with down scan imaging and the sonar, gps, etc all work, but I get a black screen for my down scan. It shows depth fine, but no images at all. It is a through hull install and I used the humminbird through hull mounting kit.
The kit is essentially a plastic piece that adheres to the hull and then is filled with marine grease then the transducer is strapped into the grease per the instructions. I made sure that the grease doesn't have any bubbles, etc but still no image. Going to try to take out transducer and see if I get a down scan image holding it in water.
Anyone ever run into this? searched internet and all I could find was send either the unit or transducer in to humminbird...wanted to make sure i am not missing something before i do that...
Thanks in advance...
