I think what kosmo was referring to was that because the 200kHz 2d sonar beam is only a 20° cone... If it shows on the 200kHz 2d sonar - it should show on the DI...

Conversely the 83kHz 2d sonar beam is a 60° cone... Returns could be picked up in the outer fringes of this 60° cone, but yet "not" show on the DI...

Here is the HB Dualbeam 83/200 2d sonar cones..



Also realize that these cone sizes are for the DI from SI series units...

The HB dedicated DI units have different cone angles (and frequencies) for the 2d cones...

Here is the specs for the HB Dedicated DI units...



(Kosmo has 1 of each type HB unit..998c SI & 597c HD DI...but I'm pretty sure he was talking about his 998c SI as the "split view" in his original post is "side by side" like a 998...instead of a "split view" of "over and under" like the 597...I think...lol)...
