Mark,
I recognize your wishes, but some of the settings you mention are not critical because most images presented here come from viewers and are not screen captures from the units. Images from viewers, like Humviewer and SiView, which have much better resolution than screen captures, are not affected by instrument settings of contrast, sensitivity, sharpness, scroll speed etc, they show the raw recording without any after processing. That's why the only critical and reported info is about frequency, cable length, towfish/transducer altitude and speed.
Regards,
Rickard
