Hi Russ,
Not sure I understand your comment about "2-3x your depth for best image quality" .. what should be 2-3x your depth ?
i beleive he may mean if ur in 10 ft of water you wanna set the SI to look only 30ft to each side. and hes right, you will get alot better resolution. i have mine set to scan 75ft each way and get really good resolution in all depths. theres tricks to it, chart speed combined with boat speed is very important, if ur going to fast and the chart speed set to slow or vice versa i dont care what you adjust you will not get the best possible resolution. that along with not staying in as straight of line as possible is the biggest factors that affect resolution. adjusting contrast,sensitivity,color pallette etc... will get you know where fast if you dont do what was stated above first...
Shawn - are you using Lowrance or Humminbird? I too keep mine set around 75' for sidescan when I'm in 20' or less. I usually stay in 12-20' zones year round too.
As far as a 4' river.. well, you can scan out as far as you want - but you won't be able to see much detail on a small screen. I've got 8" screens on my fish finders, and when I get to that depth, I just switch over to down imaging or only have left scan or right scan on independently. I think I usually get around 20' out to one side when I do it like that. You can go out further, but it may not be quite as clear as if you were in a little deeper water.
