800Khz High Detail Side Imaging

[Doug Vahrenberg]

I personally don't use the 800kHz due to it's more limited coverage area versus the 455kHz; but I was playing around a little today and scanning the river bed and flipped to 800kHz and got some interesting images. Might have to start playing with it more as it offers a different view of the underwater world. Check out these images of the old river channel below one of my local lakes.

Whats with all the clutter on the switchfire image?

Also, whats the hard white line on the boulder or mound?

Just trying to make sense of it all.
