Thread: 997 settings

I hate to ask a questions that's probably already answered somewhere else but I sure would love to get some thoughts on how you've got your SI units set up, chart speed, sensitivity, mph, etc......I played with mine more these past weekend than ever and just don't feel like I'm getting the pictures I should be getting....

I have most of my setttings on their defaults. Many here say that your chart speed should match your boat speed. (I like to run mine 1-2 above that) Others have also said to set your side imaging distance to 2-3 times the depth of the water you are in but I do not go by this. I have run mine 150' to either side and have found strucure, though lately I playing with 75'-100'.

Most of my settings are middle of the road. I have lately been running my chart speed on 10 no matter what. It might elongate the structure, but I feel this gives me a bit more detail, since at most any speed, you pass something very fast. It is only in the beam a short time.

The last update gave us control on the TVG. I'm not sure I'm liking it. I was doing better with it the old way, thus I am leaving it off or only on low.

Chart speed for me is 5 or 6. Any faster I'm not getting all the info.
I have to change setting's with water depth how far I'm shooting out the side. If the water is shallow I don't run the SI out over 75ft as this gives you the best pictures.

This one above is 12ft deep and out the side 86 ft. Some people try to set the unit and never change the settings. It does not work as good doing this. Also these shots are from the old unit the 987c-SI

This shot was me finding a school of crappie in winter time. On a lake I had never been on. In less then 10 minutes I had found these. Then caught fish out of this school of fish also.
But if I had not changed the settings, I would not have found these.

Shiloh, what do you think about running the chart speed on max? My thinking is when we look any picture, we zoom in for details. There are two ways to make the image larger (zoom). 1) set the scan distance to a lesser amount, thus giving the image more horizontal room. 2) by setting the chart to max you spread out the data available. The frequency is plenty fast to gather all the date of the object, but by using a lower scroll, I feel that it is forced to compress the image. I feel the faster the better.

Both of these demensions could be thought of like drawing on an inflated balloon. IF you let some air out, the image gets compressed and is harder to see detail. If you add more air the same info is still there, just more spread out and a small detail might be seen.

Maybe I'm backwards, but that is what I am thinking.

Hey TO64...I really enjoy your videos on youtube...I hope you will be adding more in the future....

They are very informative....

WOW is all I can say about the SI

The faster I run my Chart speed to me the less I see as in the real world. With it set around 5 or 6 I see what is there. Run by something sticking out of the water with the chart speed at 10 and then at 5 or 6. And see what it looks like. ON 10 I only get part of what is there. Its scanning so fast that even a dock does not look right.
Now if your running say 7 or 8 MPH (I run this fast at times) I have my speed bumped up to 8 or 10 then. AS to keep up with what is there with the boat.
Just like this shot of a school of bait fish and fish feeding on them. You can see each fish around the school of fish. If I had the chart speed on 10 they would not show up as good.



Or this dock Scanning under it.
