I have purchased an ONIX 10 SI unit. I am at the end stage of installing the the transom mount SI transducer. Please reference page 15 of your installation guide for this unit.
On the right side of the page then top figure where it refers to the headed pin, screw, nylon washer and SST washer. When the transducer secured/tightened down with the headed pin as a pivot and the hardware is tightened the transducer is still able to rotate a few degrees. This does not seem right as with this set up the transducer will be able to wobble up and down for the few degrees of movement when underway. This certainly would change the angle of attack/signal of the transducer at different speeds. It is almost like the black plastic pivot piece that actually attaches to the transducer has a bottom tap that is too short or the metal bracket is not to specification.
I have had 4 different Humminbird fish finders over the years and the transducer was never allowed to wobble/pivot like this transducer is allowed to do.
The metal bracket is securely mounted to the boat transom. The machine screws that are tightened with the allen wrench are tightened. But the transducer still can pivot on that headed pin assemble.
I talked with your customer service today on the phone and Beverly said that the wobble would be OK. I find that a little hard to swallow.
Please advise concerning this wobbling/pivoting transducer and tell me how I can get consistent reading with the transducer wobbling up and down. I think it can pivot up and down about 5 degrees. The transducer would have one angular relationship with the boat at slow speeds and another angular relationship to the boat at speeds where the water pressure was enough to press up on the transducer having it pivot up.
Thank you for your prompt assistance.
