1st test...

*Put the "Beam Select" on 83kHz...
*Put the "Imaging Frequency" on 455kHz...
*Get a clean straight full screen history in SI....(your normal scanning boat speed and Chart Speed)...
*Open a zoom box on the vertical line where the water column meets the bottom detail...
*Zoom all the way in on this vertical line...
*Take a screenshot...
*Post the screenshot...

2nd test....

Rickie,these are using the 83 on the 2d.i don't believe that there is a noticeable difference in chart speed between the two.there is a big difference in chart speed with the si range way out though.
