I just bought a 597 and not sure if I have this setup right or not. I’ve got the factory defaults and today was getting a picture like this.
On the 200khz lots and lots of stuff on the screen (switchfire set to clear mode, sensitivity is 10) and hardly anything on the 455khz view.
I know the river is high and dirty right now, not sure if this is normal or not. On the DI view (455khz) I seem to be able to get decent readings of sunken trees and what not, I think I have this mounted correctly.
sensitivity is too high
back down until clutter disappears
Looks fine to me. In that shallow of water, on a river, there will tend to be a lot of debri that will cause false fish echos and clutter up the screen. Different depths will require different sensitivity settings. On my 797 in shallower water I turn the gain down a little (7-8). In 20+ fow I will have it set at 12-13 and as much as 15. I like to run it just high enough so the little dots similar to the left of the screen capture just disappear.

That is it exactly. I have same unit and in December when the flow was nill the screen would be crystal clear, and now, very much like yours. Its a great unit enjoy!
When running my Hird 90% of the time I have my sensitivity up so I can adjust as bottom changes, or depth.
x2
same with my 798
more junk in the water and you are picking it up on the graph
Thanks, nothing like getting confirmation from someone with exactly the same finder.
I’ll try cranking the sensitivity down a bit next weekend. This finder is much better than anything I’ve ever owned (and does about 600x as much). Upgraded from a Piranhamax 160 which is a kids toy compared to this thing.
On another note has anyone used the Navionics SonarCharts? I fish pool 6 and 7 a lot which aren’t mapped real good….supposedly you can upload your own sonar recordings and they update their charts with ’em. Would be great to get better maps of the area.
