I'm working through a variety of new Down Images collected in rocky areas....places that have many small rocks, a smaller number of very big rocks, and of rocky wing dams in rivers. A few images are included here. As soon as I have the article finished up, I'll let everyone here know. In the meanwhile, for more Down Imaging information, be sure to check out the instructional pieces at the link below:
An introduction to Humminbird's Down Imaging technology
do you see any fish in these pictures?
Here is one large fish, either a walleye or a cat, sitting over some rocks.
Here is a group of smaller fish riding high on the back side of a wingdam.
how in the world can u tell that is a fish? that thing is at least 2 1/2ft high. it looks more like a hurdle
nice pics though
what makes you think that is a fish?Quote:

From all the posts Ive ever seen on this site Ive only really been able to point out fish a few times on si and down imaging and that is only when there suspended off the bottom. On the bottom i cant tell crap. We catfish on the ohio river and 2-d sonar is still better than even this special "down imaging" and "sideimaging" because atleast I can tell there are fish underneath the boat. To me if Im gonna have $2000.00 sideimaging unit, I want to be able to easily identify a large fish laying on the bottom Ive had folks say on a screen shot that the white streaks that im seeing in side imaging are fish, then others say its a branch lieing on the bottom. That is worthless for the type of fishing Im wanting to do. I can tell you what either Humminbird or lowrance needs to do. IT WOULD CLEAR UP A LOT FOR THOSE OF US WHO ARE SO CONFUSED BY WHAT FISH LOOK LIKE AND HOPEFULLY A HB OR LOWRANCE EMPLOYEE WILL PASS THIS INFO ALONG! I know that in dirty water you could not do this but in saltwater it would be possible. For those of us that are confused on what we are seeing on these down imaging and side imaging shots think about this. Would it or would it not clear up so much especially on what fish would show up as if they could run the split screens and have an aqua-view camera rolling???? Ive said this ever since these high dollar units came about. If That 2.5 tall symbol is in fact a large walleye or catfish how in the heck could you tell. No matter what your answer is it will still be hard for many people to believe. Doesnt look any different than a piece of structure on the bottom. The best think they could do is run the split screens with an aquaview running to prove what is being seen on the downimaging and side imaging. Yeah its no problem to determine a boat lieing on the bottom or a car but its still not helping me locate the fish.
That is because there is no such thing as a fish finder.;)
Heres fish and I find fish with mine each trip. For people that think they don't show fish. Heres some shots with fish. And caught fish out of them.
Also have some from last week where i found fish 150ft left of the boat. Marked them and took the trolling motor with the waypoint shared between the units. Went to that spot and caught 7 fish fast out of a ball of fish about the size of a couch. Theses are still on the SD card will try to get them on here also.
Around 75 crappie were caught from this one also. Show fish in 2-d and SI also.

This one shows baitfish and you can see each fish around the bait.

Does that mean the fish was moving?Quote:

"Does that mean the fish was moving?"
That is correct. If the transducer is not moving, and nothing passes by, the entire image will be streaked by the screen scrolling. A fixed object, like a tree or stump will make a long line. Also, fish have to be moving the right speed and direction to make a good shadow. In this example, the fish on the left isn't too bad - the ones on the right aren't good at all. If there are a number of fish passing by a stationary boat, some shadows will show up very well.

Fish ID clutters up the screen two much for me. But it does show fish where I see fish on the 2-D screen.Quote:
