I was kinda wondering about that, seeing as how the slanted line on the screen looked almost like it was in Down Scan mode. And the sonar circle in the upper right of the screen looked similar to the Perspective mode directional icon.
I can almost "assume" that he may have his transducer tilted forward a click or two, which may be the cause of the slanted line being so long back towards/under the boat. But as far as buying a LS34 just to get the sonar circle .... uhhh, nah, I don't see me going quite that far, even though I'd love to have that option.
