Seadog,
You posted two screen shots, one where it looks like your in the water and the another when you are out. Since these two screen shots are completely different can you repost only one so I have a better idea of these vertical lines you are referring to?

Seadog,
There are two things that I see see in your screen shots. First is the tail of the bottom is much weaker in your unit than your friends. While you have doubled checked that the wiring is correct, have you double checked that your transducer setup is correct on your machine? If you are sure that is correct, I would then do a system reset (Restore default settings).

Seadog,
The Demo mode is a learning tool and not very useful for trouble shooting.
Your last screen shot is showing your HF gain setting at 0.1 and your in 200ft+. For me, that is a red flag. I would like to see a screen shot showing both frequencies while the vessel is at the dock. If you are 10ft of water please set the range to around 50-60ft. Set both gain controls at zero. I want to see how the LF compares to the HF side.

Seadog,
Thanks for that. Is see two things in your screen shot. First the HF side has more returns than the LF. Second is that the width of the primary return really doesn't match the beam width of the transducers you are using. So what I would like you to do is at the dock (not moving) is to take another screen shot after you reset (restore default settings). I need to see the returns when both the LF/HF have exactly the same settings. Your transducers (82M and 9HR) have a four to one beam width difference, below are screen shots of what bottom returns will look like using transducers with a three to one ratio. Also with the settings the same the LF and have more returns than the HF side. I would also like to see a screen shots of the Transducer Set-up and Frequency Choice menus.

Seadog,
If you mounted the CA38BL-9HR in a box that would explain why your CA200B-82M has more returns. Just know that transducer was not designed to be installed like that and in doing so you have decreased its performance by roughly 30%.
So going back to your 82M, I can see by where and how your transducer is mounted it is going to be susceptible to turbulence depending on sea conditions. I trust that you have defaulted your settings which should have reset the TX Rate to Auto. Next time out if the bottom appears like you have seen before reset the right side of the display from 0-250ft (not shifted like you have) and change the TX Rate from Auto to 17 to see what affect that has.

Seadog,
I am here to help, but unfortunately I am not on your vessel to do the tests I would like to do. If you feel that the sounder has a issue please feel free to take it to a dealer to have it checked out.
