I'll post several pictures that I have captured as screen shots. I'm new to the entire SI thing. All of these are taken from a HB 798. Is this as clear as I can get with a 798?

The horizontal black lines (that are not indicative of structure shadows) are usually a sign of turbulent aerated water flowing across the face of the xducer...
If we eliminate this issue...your pix are actually pretty good...
Can you post pix of your xducer installation ...??

I personally dont think the images are too bad. Are these pics of your screenshots, or been uploaded to computer and then enhanced? Can probably get a little more detail with increasing image size, and ya can do that by just setting the screen to show just one side of the boat at a time. Also switch between pallets to determine which color shows the most detail. Outside light can cause the need for a different color pallet each trip out. When ya stop the screen on something then you can experiment with these different pallets and settings to get the optimum image. Great shots man, keep em coming. I love these kinds of threads!
Learned something new again Rickie! I would have thought the lines were RF interference.Quote:

I can experiment this way until I find the optimum place for the transducer and then mount it permanently. I will adjust the mount and get the lines out that are not part of the structure. That will probably take care of my poor screens at speeds above 3.5 mph.Quote:

I appreciate the quick feedback. This SI is exciting and fun. I have already found I can burn up a lot of gas riding around "looking" at stuff.
OOOOOHH but ain't it fun!!!!!
good shots, keep them coming after ya get the mount in.
Black horizontal lines are usually aerated water (bubbles blocking minuscule sections of the sound pulse)...Quote:

Light colored horizontal bands (of a lighter color of the same Pallete color)..are usually TM interference...

"Sprites" on the SI image are usually crosstalk from another unit or just errant RFI...

THATS GOOD RICKIE,GOOD INFORMATION,ARKCRAPPIE,GET THAT DUCER CORRECTED AND YOU WILL HAVE IT:ThumbsUp
Thanks for the excellent tutorial Rickie!
The images aren't bad at all. As for the interference I will use the info I gain here to help me properly mount my 899 on a boat when I get it built....I don't get much interference from a kayak....LOL. One of the things that really surprised me after using si is just how barren the bottom is in some lakes. Fishing with an si unit is addicting. I fish 4-5 days a week and I need to send the 899 in to get the 800 kHz problem fixed but I don't even want to be without the unit for one day...LOL. Keep up the good info all.
Regards
Pictures are not bad, but Rickie is right.you should be able to clear up the water column area and that will help.something that I think helps to while setting up your unit is to watch the screen while your outboard is running, then turn the outboard off to see if the image quality changes.
I'm being very cautious with how and where I mount the transducer because of the lakes I fish. Reelfoot is one example. Sliding over one stump can wipe out a transducer. I see it every year over there. This is the first time I've had a console mounted anything on my boat. When I get to the point I have the SI unit figured out and decide to leave it, I'll make something permanent. I wish I had the luxury of fishing lakes that are not full of stumps. I just have to figure out how and where to mount the transducer so that I'm not buying 3 or 4 transducers a year. That could get expensive.
Pictures 1, 6 and 7 were taken on Reelfoot Sunday. Several of the stumps and logs are visible. I had some others I took while around some lily pads (lotus). Those showed up as hundreds of white dots. Here's a couple of shots that I captured just prior to getting into one of the ditches. I guess the deeper line is part of the old bayou that runs through the lake.

I forgot to answer an earlier question. Someone asked if the pictures had been enhanced. I guess I'm not that savy with this stuff yet. All of these pictures are uploaded straight from my SD card. Are there enhancements that can be done to improve the image quality once it has been uploaded to my computer?
I'm glad you mentioned reel foot lake.the quality of images that you get will be best on a hard bottom.reelfoot is definitely not a hard bottom lake.im guessing that your not going to get much improvement in image quality there.as far as those stumps go, I can see were your concerned
I have been told once uploaded to your computer, you can open the images in microsoft paint and then edit or enhance the image. Like deleting gps coordinances and stuff like that. Also supposed to be able to clear up the image, and draw lines on it to point something in particular out. I havent done this yet, been told about it tho.Quote:

It may not be, but I hope it is possible to see that, im going to pay more attention from now on! Man im getting excited now.
Sure is awefully curvy to be a beaver tho, now that I have looked at it more. But im still excited!
LowePro, I am familiar with Microsoft Paint enough to do a little work in there. I just didn't think about putting my screenshots in it. I have to use Paint for work applications all the time. I try to leave my work at work and not cross the two.
That run is pretty long. I'm thinking it may have been created a few years back when Reelfoot got really low and that area of the lake was dry. That's probably where the last bit of water was draining to the south. I saw a lot of stuff in that really shallow water. The SI picked up more than I ever expected in less than 3 FOW.
Kosmo, that's good to know about the soft bottom/hard bottom. I fish several oxbows, but I also fish some other lakes like Kentucky Lake, Dardanelle, Greers Ferry, etc. That will be good to see this thing in use on one of those lakes.........

Just wanna add something to make the trip there every month to be more worth it.
I'm just the opposite. I catch crappie up there on most every trip but I rarely catch a walleye! It's a great lake to fish. I'm curious as to what the side imaging will look like in 30-100 feet of water.
Paint can be used to zoom crop and point stuff out but the impression of actually "inhancing" it is not done. The shot that comes off the card is what you have.
this can be seen in a earlier shot I posted then went into paint to get a zoomed shot of structure. I would think that if a shot was made to look like something that was not good to begin with would be altered to give a fails shot. Paint is a great tool in scouting when used with HV and HumPC.
Low if I gave that impression then I apologize.
As as shallow as that is and with having more than one I would lean toward someone not know where the trim button was lol
Slabbacks, shallow means nothing. There are regularly people running wide open with anything from 5 hp up to 250 hp. Reelfoot is notorius for claiming several lower units every year. I am actually one of the very few that drops off plane in that area.
Maybe someone could explain the use of Humviewer and Humminbird PC to arkcrappie (and to me!). I think they take recordings and snapshots from sd card and put them on these software programs. From there all of your unit controls (zoom, pallette, sensitivity, contrast, etc) can be changed on your computer. I think lots of detail comes from the computer that isn't able to be seen on the water....at least I think that's how these guys who are really good are doing it.
Ark I've always said that lake would come off the bucket list some day but I also think the unknown and the stories of loosing a lower unit has held me back. I've seen some great px come from up there...ice cover...glass...to the wind making it look like the east banks. With my luck if I went, you next shot would show several more cuts in the mud and a nice shot of a lower unit :Rofl
Just don't run wide open over there unless you are positive about where you are!! I run a 70hp motor and there are places I run full out, and many more I idle. Lot's of structure to hit in the right places. PM me if you ever head that way and I'll give you all the help I can.
Humminbird PC is navigation data management...(it is a free program available in your HB account when you register your unit)...Quote:

HumViewer
Humviewer has better tools for manipulating the recordings than playing the recording on the HB unit....
