Topic: First Pics, need a little help tuning

[vahntitrio]

Taken with a new 798, they didn't look nearly so grainy on the head unit. I believe sensitivity is at 12 and the SI Enhance is set on low. Should I lower the sensitivity to clean this up a bit? Turn enhance off completely?

The main thing is up here in Minnesota on natural lakes there is very different structure than the saltwater or southern reservoir guys see. There really isn't anything well defined enough to fine tune this on the water. The main thing with those settings is I can find weedlines, and I can find oddities in the bottom. I just want to clean them up a bit to get a better idea of what those oddities might be. For the most part I will be fishing less than 15 feet of water.

Large Muskie off to the right (it moved from 1st to 2nd pass so I know it's a fish)


Downed wood to the left, thick weeds (curly-leaf pondweed for those familiar with it) to the right.

I wish my images looked that good.  Turning down the sensitivity a couple of notches will darken the image just a little.   From my experience getting that good of an image in 7' of water is not the norm.

Yes, lower the sensitivity to darken the view. Think of the sensitivity setting as a brightness adjustment. Although I fish waters with a lot of features, some areas are quite plain and still have something interesting. I caught a couple of mid size bass from these:

What I always recommend is to make a recording and play it back.  Then you can pause it and fiddle with all the settings to get the best snapshot.  This is also really good learning tool to understand what each setting will do and how it affects the image. 

By the way, these are some very nice images for your first time!  Keep em coming and certainly would liek to see some submitted in the month Image Contest.
