sonar images

I thought I would share a shot from a recent trip. Surprisingly no fish were there, or at least willing to bite. I am using a HumminBird 798ci SI Combo. This shot was from a run about 5 feet to the left of center along a laydown. You can see there is good image from the right side of the side imaging transducer and a "ghost" image from the left side of the transducer. Apparently humminbird side imaging has a small overlap from side to side, a tad cross-eyed if you will. The deeper the water the more pronounced the overlap. I was wondering if Lowrance has the same issue.Attachment 147661

Here is another shot, different tree side by side with regular sonar and side imaging. mAttachment 147662

Man I would love to fish that about March!! Great image Fishers! If you turn the Contour Mode on or off (can't remember which) you will have a nice pretty picture, but you will loose the water column.

I am running an HDS8 and mine does the same thing

Good to know, thanks!

Remember your angles guys, you must drive over the brush perfectly to get clear view. Plus if the brush is on a slope it will appear better on one side or the other. EB

I do not see the overlap on mine. As EB said, get far enough away and for the cone to concentrate on one side, but i have not noticed it on mine. Was showing Achiro the rooftop Saturday and it was only on one side.

Sounds like you guys need help understanding side imaging. You are not getting a ghost image of the tree. You are looking at the water colum under the boat and catching some of the tree on the left also. If you were to use the Down scan, that would only show some of the tree but the structure scan will show more as it goes futher out. If you need any more help, I would love to help out. Go to DoctorSonar.com and Doc will explain this to you better or ask him on Thursday at 7:00pm as he will be a guest here on CDC.

Shane, I spoke with you and BEBE sat when we pulled out. My LSS1 transducer went out, I replaced it 2 wks ago with LSS2. It is mounted to the bottom of my jackplate. Once i get above 6mph it goes away. I am ok with that bc of its location. But, when i come off plane or back below that speed, The down and sidescan scroll super fast, white, and flashes 5.0 for depth. Is what helps most, if boat comes to complete stop, reverse for a little turbulence, then forward, it generally clears out. sometimes this can take 4-5 min to clear out. The 2d sonar becomes grainy at this time also. it is mounted at the bottom of the hull like they should be. It happened occasionally with my LSS1, but not enough to remember the last time. Turning the unit off, and restarting does not help either. Suggestions?

I would love to help you but I don't remember much about your boat other than it's size. If you want to take a picture and send it to me, I might be able to help before this weekend. If you want to wait, I can help out sat. You can email me at [email protected] or call me at 316-323-0010. By the way, this is Jim and I Saturday going north. I am glad we were in his ranger and not my Triton..

Yowsa! Did you find open water after all that? We didn't even try it in Ledge's boat and I wouldn't have in mine either.
I just want to figure out how to see my jigs on the front HDS5 like Ledge had going on, that was awesome to know if you are above or in the brush! I've got the HDS12 touch and another 5 at the dash. One transducer on the back and one on the trolling motor. Its the trolling motor sonar transducer I need to figure out.

Give me a shout on Sat. I will help you out Achiro.. No we didn't find any fish after breaking up the ice. That was the bad part.

Maybe this will help you.

I can't see any ghosting in the picture. I see the contrast needs some tweaking. I think the shadow is what you are considering
ghosting". If anything is casting a shadow, that's an indicator of how far it is hanging above the bottom. One end of the tree the shadow will be close, then as the limb gets higher, the shadow will be futher away. Make sure you have a look at the Down scan while over the same pile.

Swollen, get your LSS2 off the jack plate and onto the transom in a proper spot. You're getting a cavitation issue with it mounted there. You should be able to clearly read the side/down scan at much less the 6mph. It all depends on the speed settings on the unit. I was getting a clear picture creeping past items at around 1mph.

Everyone should remember when passing over something so nice, the time you have seen the full image on your unit, most of it is behind your boat a ways. I toss a marker out, then will cross pattern it once or twice using the bouy as a marker as to where I really need to fish.

Craig...my LSS is on the bottom of the boat, not on my jack plate. I just thought what I was seeing was normal because it seems as if it would make sence if you pass directly over structure, you would probably pick it up on the right and the left of your side imaging screen with one side being more clear then the other. But now I am hearing this isnt normal, so how do you make a uint not show structure on both sides if your passing over the top.

These are great questions and you guys need to sit in and ask these questions to "Doc" Doctor Sonar tomorrow night at 7:00. He will be the guest on CDC for one hour. get your images and questions ready.

Well I guess I might as well add my two C's. This is how it was explain to me. I have a HB 998 SI. Remember you are only looking at a small slice of the water column as you go over structure or fish. Please see attached, I hope they are readable. Look at #1 first then #2Attachment 147926Attachment 147927
