My new 998 hd si ???

Not so sure if i did the right thing. I fish Lake Dardanelle, Arkansas all the time. I have been out with the new toy several times and the unit itself does a great job, so far no probs except I can't find brush piles. I bet I have marked 50 potential brush piles just to go to them and find nothing. I haven't figured out yet what exactly I'm looking for on the screen. I have passed some piles I know are there just to see and there might be a little sqiggly looking something, but when you see my snaps you can see why there are millions of squiggly things. Picture#1 is a typical shot anywhere near a creek channel. picture# 2 is where I am crossing a submerged paved road and what I thought might be some brush to the left. But none there. Sometimes I think maybe there is so many fish showing up the beam can,t get through the fish to get to the brush. Its got me scratching my head.
Any fish here??

Someone who knows SI, please analyze this next shot. All i care about is finding brush. I have been fishing this lake since 1965 and have caught hundreds of limits of crappie, I just want to understand this new Hummer so I can find new places. Thanks

Ray, the last shot looks like fish. Lots and lots of fish. The larger white returns may be some kind of structure, but a person may need to zoom in to see for sure. One thing is for sure. There are lots of fish in all those pics. I'm sure the real experts will chime in before long. We fished the Clarksville end, and there wasn't a whole lot of structure in the bay we fished. I'll go back and see if I have any pics from there.

you're not trying to see the brush with the downscan feature I hope.
just use the si to mark brush.
you may not have scanned any good piles yet

set the range to about 3 times the depth. maybe just look to one side. will do wonders couldn't that be brush on the road on the left of #2?? something is casting a shadow there.

I don't see any brush shadows in any of your shots...(lots of fish tho...)

Here is an example of the shadows you should be looking for...
(the first shot is the actual screenshot...the 2nd is explainations of the same shot)...

Place waypoints on brush piles (in the SI image)...at the exact spot on the lake bottom where the structure touches the shadow...

Then reposition the boat to slowly pass over the waypoint watching the split screen Sonar/Chart...
(Be sure "Beam Frequency" under the "Sonar" tab is set to 83/200 to get the wider 60° 83kHz sonar cone)...

If the brush does not show up in the Sonar view...switch back to SI and see if you missed the brush left or right (and mark another waypoint on the SI image...)

Like Brett mentioned...DI in the HB SI units is "lacking", at best...you will have better luck spotting brush on the SI and then verifying the brush with the 2d...

Thanks for the advice and hello RCC. Right away I learned that the DI was of little to no help to me. On that roadbed shot, I did check out what I thought was brush but it wasn't. Rickie your post was a lot of help, thanks for the time and trouble. I think that 3 times depth is a good rule so I will be trying that next time out. The next shot is about the closest I have that resembles yours. I can't remember if I found brush in it or not. I think it has some in it. The next one is a 2d and DI comparision. I like the 2d better. I'll get the hang of it. The key is to keep using it.

The 2d looks like brush whereas the DI looks like a little turbulence.

Ray, here is a pic from Lake Nimrod. Buncha stumps with a few fish thrown in. This was recorded on a 798 and viewed in Deepview. You can roll the cursor over to your target and see the GPS coordinates on the bottom left.

This was a shot I had Sat. in DI/SI. Just getting started as well with my unit but these guys have given a ton of tips that really helped me with the learning curve and hope to learn more.

After making changes...going over a target...making changes ect, I was able to find the settings that gave me what I felt I should be looking at. The best part about it is: To learn it, means we get to go out on the water and fish:ThumbsUp

Why wouldn't he want to use the downscan to see the brush? I use it all the time, with downscan you can see the brush and actually see fish in the brush. With sonar, you just see the red/yellow return from the brush and it is impossible to tell if fish are actually in the brush.

My sentiments, exactly, SYG :ThumbsUp

Exactly why I don't miss 2d sonar !!! My E5DSI is downscan only ... and I look at it waaaaay more than I ever looked at my previous 2d DF's !!

... cp :kewl

I bought me an HB 998 about 9 months ago. I have not taken the time to really figure it out yet. I seem to want to fish more than figure the unit out. However what little time I have used it I am confused at times and amazed at times. I really only know when I am in 2d and SI view. I do not really know what the down imaging view is on there but I think I may have an idea. I get really good returns in deep water. I do not even really know how to set it up much. The brush shows up almost like a mirror image, I can see every little detail it seems. However, in shallow water say 8 feet or less I see nothing. I have tried adjusting the depth but it does not seem to matter. What shows up in deep water shows up really well. What is in shallow water does not show up much.

X3 I very rarely use 2d anymore except on plane at speed. I use the DI to fish with.

What Beam width are you using in DI? (sonar tab: Down imaging / Beam width)

not really sure slab what should I be using

di is the best thing on a depth finder, most detail and by far the easiest to see what is there in my opinion

x2 clfarms1, had two DI units then switched the console unit out for the SI unit (with DI). DI is just like anything else its a tool but thats one tool I dont want to be without.

I used a wide beam Sat. in the 20 fow or less with DI after I found something I liked in SI. The DI, like these guys said will show all the detail ya need about the structure to include where the fish are at..ie in it, above it or hugging the bottom.

The reason I asked what beam was used is it seems that a narrow beam in 8fow or less, you could miss a piece of structure just to the side. You may be going just past something. The other thing I thought of you spoke of already...making sure the upper and lower range settings were right for that area.



Maybe one of the guys with more time on the unit will chime in and see if I'm on track or shooting in the dark.

You are on track.

use what works, my 998 gave me very poor results on the downscan, si was excellent

I tired to tell you to go with lowrance.......glad you got you one though.

Uh-oh.......:)

hey, I have HDS 9 touch, I love it,

You don't get good DI results with it? I have a 9 touch also and I get pretty decent detail. You have to be going at least 3-4 mph to get a detailed image. If you troll or sit on top of it the image gets elongated and blends together...........you probably already know this, just trying to give a suggestion for better images. I use mine on the factory settings in 455kz almost all the time and think its amazing.

I'm good with mine, used it today, found new brush, 1 had fish, 9 total

Update to the newest version of the HB software. Latest is always greatest!!! Enjoy the new unit. Don't listen to negative comments.
