I have the upgraded ducer. I did upgrade at point of purchase just because it is cheaper. But I normally ALWAYS run mine on the 455khz. Which is the same khz setting your basic transducer uses. You should be getting beautiful images even at the 455khz with that unit. Make sure in your menu that you have the right transducer selected. Believe it should be the SI compact (if im wrong on the selection someone correct me please). If all that is matched correctly plus what is mentioned above....then the structure is just not there. If it is there.....the graph will show it. You have a great unit.....now "trust" it.

The correct setting for the stock XNT 9 SI 180 T (Compact Sidescan xducer) is listed under the "Connected Transducer" menu (under the Sonar tab) as simply "Sidescan" ...
This setting enables the 83kHz/200kHz transmit frequencies for 2d and the 455kHz transmit frequency for SI/Blended DI ...

For the Helix 9 SI, the default setting for Connected Transducer should be for the compact transducer ("Sidescan"). If you upgrade to the HDSI transducer, you will need to change the Connected Transducer setting. Also, anytime thereafter if you reset factory defaults then you will need to change the Connected Transducer setting.

cjones,on your helix si ,if the brushpile is old,small limbs,not in water colum and if hard bottom ,it will not show you those limbs,yours or theres.what you have to do to help you on older brush is to train your eyes and the best way to do this is to find a good pile and put a marker on it ,then go over it just far enough that it will not be in water column,stop unit by hitting cursor,then adjust it as good as you can,after that look at it until you know what you are seeing,it will usually be a light spot with a little shadow behind it.do not range out too far and for practice ,just use one side to give you a bigger pic.go by it at different angles and see how well you can pick it up with unit and with your eyes.All of us have a tendercy to think of our units as greater than they are,we see fish and brush that just jumps out on the screen but fail to take into account all those times that we miss seeing piles that we pass by.practice is going to be your greatest friend,and being alone is the best way unless you have someone more knowledgeable than you going with you

Cjones, did you make it out this weekend? How did it go?
-
Made it out but shortly into my trip hit a piece of debris in the water and spun the hub on the prop so the trip got cut short. Hope to have it fixed and back out Saturday so hopefully I have a report this weekend.

Finally got out and got to use the unit a little. I appreciate the help because the wrong transducer was selected and a couple of other things that were mentioned needed adjusted as well. Still not seeing the brush/fish like I thought I would(based on others pictures I see posted) but still trying to train my eyes and get it a little more fine tuned. I forgot to take a screen shot but will try to do that and post it. Thanks again for the help.

It is worthy of note that most of the pictures people post of side imaging are when they run over something really cool looking. Like right over it. It is easy to see stuff right under the boat on SI because it basically looks just like a regular display. When you view things way out to the side they look wierd most of the time and there is nothing to be done about it but figure out how to interpret the image. This is coming from someone who is still learning btw so dont think i am being holier than thou.
