I just added an LSS2 to my HDS 7 touch. I did not change the setting for the 2D.(83/200/455/800)
The LSS2 is on a different cable to the DF and I think when it is connected the side scan and down scan default to the LSS2. Played with mine for the first time and I am not getting the clarity and object identification that I have seen posted. I obviously need to tweak my setting. I ran beside a dock and the pilings showed up as very thin lines almost unintelligible so I must not have the gain or something set right.
I am referring to the side scan images. The down images are fine, but I was using them on the other transducer before I added the LSS2.
