SI And DI whn sitting still

i read a lot of forums and try to learn everything i can about humminbirds and electronic in general. most people say si and di do not work for marking fish when you are not moving more than 1 mph and your scroll speed set to match. i say hogwash. me and jigslinger were fishing a bridge the other day. and marking very little at all. i looked down to see the screen and watched as this shool moved up to this pilon and stopped. in the shot on the left you can see them coming to it from the upper right. the lines are kind of strung out cause they are moving and we are not. then as they stop next to the pilon you can see them more like they would look if you were moving and scanning the bridge.you can also see them in the 2d sonar. they dont apear as arches because we are not moving and they are not passing all the way through the sonar beam. in the pic on the right you can see the fish stacked up around the old bridge pilon under the newer bridge, in this pic we were not moving either.what do you guys think. and what is your oppinion on this

One thing we know for a fact is crappie are always on the that old piling...and sometimes they go into a feeding frenzy,and there mostly nice fish! The only thing is timing.... being there when it happens!

Most times we dont get a good reading when sitting still, maybe with the wind blowing hard as it was we could have been moving more than we thought?

No when I took the screen shot we were at the end of the pilon and told you to look at this screen. We had the boat pined against the edge of it with the wind. Just goes to show these things can produce some amazing images.

I've had my Humminbird with si & di for a year now guess I am going to have to get the book out and learn all the secrets and controlls.All I did last year was flip and play with it.But I see where it is a great tool when operated like it was intended.

I use that method all the time to see how the fish move in and out of the cover. You can tell how deep, what side, and sometimes which direction they are moving in.

What model unit do you have. I may be able to help you with your settings

Gtojoe what model do you have. I'm looking into getting one..thanks in advance

Hey GTO. In your split screen pic remember, the si view refreshes from top to bottom. In other words, the newest data is at the top. Your fish are moving away from the pylon. Trolling below 1mph all the time and I always get excellent pics so I throw the bs flag on the 1mph minimum thing. I try to match the screen speed with the boat speed for a real accurate picture. Too slow or fast tends to distort the image. But it will still work, just depends on how pretty a picture you want. I tend to prefer sonar for fish and si/di for structure. Just my opinion. I'm still learning it.

I see you have your side settings set at 60, will you try to explain to me which distance is best( im at 74). I got some of your settings from Danbo but I aint real good wid dis unit
Thanks

I have a 798ci SI. If I had it to do again I would save a few more bucks and get a 898, 998 or 1198. The picture is so much better. It is also capable of using the 800khz in the SI and DI.and it is eithernet ready. But at the same same time I must say the 798 is pretty incredible.

Yes I know that. In the pic the fish had been moving in for a while.. I kept watching them. I wish I took more screen shots.or a recording. There were very few fish when we started fishing the bridge. As we were holding still at the end of the pilon I watched as they came in and we started catching some. The direction they were coming from is not the same as where I stated they were coming from on the screen. Guess I should have said that.

I have a 997 when im stopped yes you turn the scroll speed to 1 mph then switch screen to di an watch the party in question . switch fire you can put a jig in the water an watch it dance not a pro at that just yet but still trying . Humminbird is good equipment go to doug venturinburg i know i didnt spell his name right you can watch u-tube for hours on anything you need to learn have a pen an paper ready quality stuff.

fuzbo try depth times 3 on side imageing and play with it from there as to how you want them to look

When I am scanning a area my SI distance is usually set to 2 to 3 times the depth of water I am in. But I change it up and down depending on what I am trying to see. Remember that you should set your chart speed to match your boat speed. When scanning.

Works great doesn't it. When I push minnows and spider rig I use 2d and DI or SI split screen. To stay on top of a school. Doug's videos are great for learning about these units. I also read all the posts on bbcboards Doug, Wayne p and Humminbird Greg are a couple amazing guys.
