If this was true then this means that the side signals would be overlaping. the side signals go out on a angle not directly down so how could they overlap, what or how does the water depth figure into it, as the deeper the water the wider the dead space between your side signals...

Notice how the side angles both contain the same tree. The tree was directly under the transducer. Unless my year and a half of using SI was in vein.

The water depth is represented by the space from the middle line, to where you start seeing the ground.

Yes I agree so look at the first pict there is 20 feet on either side of the middle line representing the dead area that side beams cannot reach in this 23 depth pict. So how can that tree be on each side? is it 40 feet wide??? Remember the side beams cannot read anything on the bottom of that 40 foot area, unless it is sticking up into the beams path.

That's not exactly correct. The transducer reads everything from directly under the boat, to the ground, and on the ground to where you set your limit. It just flattens out the image. If you go over a school of shad, or you run your boat through an area with the big motor, and the go directly bach through it slowley, the bubble, or shad, will show up in the area that you are calling dead. there is no dead area on SI. The down imaging just shows you this area in a vertical format.

The tree is direcly in the center. If you print that out and fold it in half at the center line, and the fold the edges out where the ground starts, you'd have a true representation of what the down imaging does, and how to read side imaging pictures on a flat surface.

Here is the image printed out and folded, which is the correct way to read it. If I flip it around to the other side it's identical. The image quality isn't the best. Sorry about that.

Yes U can see bubbles/shad casuse they are hi in water column near source of beams and yes folding paper trick is how side image works but u still have that dead area on bottom that's why you have to fold paper. look at Hb's image of how their si works. Oh well have a good nite, & a great Xmas

Well, i'm no professional at this and don't fish for money cause if i did, i wouldn't be here.:D I fish for fun on the weekends and that's not every weekend either. I just enjoy it and thank the lord that i can afford these type of toys. And the last thing, i'm not sponsored by anyone but myself. LOL! I dont know why some guys get there panties all in a wad when this lowrance and HB imaging comes up. Everybody has an opinion and its just that.

With that being said, i'm posting a few more pics cause the man requested them.

All these pics i posted were taken on my HDS 8. I done all my own installation down to the ducers for the 2D sonar and SS. It might could be better but for me it works and i understand what i'm seeing. I do think the my SS could be tweaked a little more. Anyway here are a few pics with the 2d sonar setup. Nothing much in the imaging pics but fish. These are at the local river where i fish. If i had to guess what type of fish, i would say catfish, garfish, spoon bills and maybe a few bass mixed in.

2D Sonar at 200kHz


The next two are with 2D sonar at 83kHz

The down scan window shows a few fish archs also.

thanks for the pictures, looks good
