Howdy Greg,
Software version 6.830
Here are a couple images I copied and pasted from the playback on the HumViewer. I was going fast so there is some prop wash.
What the heck is it?
I've got a couple of actual "snap shots", from the Humminbird, but nothing of interest.
These picts are from the "save snap shop " feature of the HumViewer. I've got the entire playback of the HumViewer, with different views and color pallets, to play with. I love it.
Only problem I have experienced with the 999 was with Downview.
My Downview was getting streaks and being unreadable at a chart speed of 2 mph.
I had set it at my boat speed. I often troll at 2 mph.
Humminbird said there is a glitch in the software. To change my chart speed to 1 mph or 3 mph.
Fixed the problem, as you can see.
Chris
