Thread: help with side imaging

For the "graininess" of the SI image...open the SI Enhance menu...:

*Try turning the "Contrast" down a click or two...
*And maybe turn the "Sharpness" down or Off...
*Then turn Sensitivity up until the image is to a brightness level that looks good to you..

(I very seldom change Contrast or Sharpness unless I'm looking specifically for fish...higher Contrast and Sharpness will help the fish echoes pop out better...but at the expense of making the image "grainy" lookin)...

(I change SI Sensitivity constantly depending on what bottom composition I'm over...a mud bottom will need a higher sensitivity setting - a hard bottom will need a lower sensitivity setting)...

I believe you are correct that those white specks around that piece of brush are fish...

thanks rickie, i just needed some clarification i guess. also the settings suggestions will help a bunch, I'm actually gonna run out to the garage now and change the settings.

I'm still editing one of your pix..I'll get it loaded here in a sec...

Rickie

ok....thanks a lot for your help bud

I probably missed a few...

About SI image orientation...

Do you understand how the information in the image actually lies under your boat ...to discern where those echoes (fish and structure)...really are under the water...??

I think so. data scrolls from top to bottom new to old I've done the fold the chart to show the water column thing so the width of the column on paper or the screen basically shows the depth. And after some research I now know that the 2d only shows a portion of bottom relative to the water depth and transducer setting.
