Helix 9 g2 Side Image distorted
« on: August 10, 2019, 04:13:26 PM »
I have tried adjusting this transducer its a mega. One side remains good its always the drivers side. But the other side is distorted. Now if I turn on max mode they both will show, but the starboard side does not any contour of the lake. 2D is great it will keep the bottom when the boat is on lane at 43mph. Down imaging is great too can see straight down like I'm looking at my shoes. But port side is terrible almost black. I can see side image straight line in in the left plane if I look good.

I have adjusted my jackplate to make sure its not blocking. I had a 798CS SI HD transducer mounted on the same spot at the new (LONG) transducer that I got with the Helix9.

What is wrong here. I have mounted any HB transducers, but this long one is making me question what is going on. Is it being blocked by my motor?
If I use a y cable and add a second transducer will I have to switch transducers to view them both simultaneously? I want to see both sides while I'm slowly moving through.

Will a second transducer draw more power?

Boat is a 06 Triton Sp175 Aluminum W 90hp Merc W Atlas Micro Jacker Jackplate. If you need a pic Ill send one.
One last point I have used the level technique to properly set the down angle. I have tried twisting the port side down by the adjusting screws, still no difference.


HELP!!!!!

The most definitive test in this scenario can be by temporarily mount the xducer to a stick and immerse it in the water deeper than the boat hull  ...

If the image resolves = the issue is blockage  ...
If the image is still distorted = the xducer or head unit is malfunctioning  ...
-----

Left and right dual SI xducers can be used with the 9 M SILR Y cable  ... Left SI would always come from the port xducer / right SI, 2d and temp would always come from the starboard xducer  ... This does not draw more power  ... The unit does not even recognize that there is a Dual xducer Setup simply because the 9 M SILR Y cable is nothing more than wires that reroute the data channels to different piezoes than normal  ....

Rickie, I have a 9M SIDBY cable can I use that or do I definitely need the SILRY cable? Thank you so much for responding!!!!!!

The 9 M SIDB Y cable is used with an additional 2d xducer in cases where high speed depth readings are difficult to obtain with the SI xducer  ... With this cable 2d always comes from the additional 2d xducer and left SI/ right SI/ DI / Temp always comes from the SI xducer  ...

The 9 M SILR Y cable is used with an additional side imaging xducer in cases where SI blockage is an issue  ... With this cable left SI always comes from the port SI xducer and 2d/ DI/ right SI/ Temp always comes from the starboard SI xducer  ...
