Humminbird side image pictures

Well I watched a couple of my HB899ci HD SI videos from the SD card today. It was very windy today with rain moving in later so I took time and watched the video I had taken while fishing last week. Please commit on what you think about the pictures of how i could have done better or whatever. I took the pictures with my iphone camera I have not learned how to use the snapshot feature yet so I am just in the learning stage on this. I did catch crappie on a couple of these places. Third and fourty picture are the same I liked them best because of the shadows cast by the fish. The last picture was a really good crappie hole caught several their. Like I said I am just learning and maybe these sonar pictures will help others learning to read sonar.

Great job scrat ...

The only thing I would suggest is to overlay the SI Enhance window on SI imaging ... this gives you instance access to the SI Sensitivity setting where you can make minute adjustments to brighten/darken the SI image as the bottom composition changes from hard and soft returns ...

You know your stuff.:fish

Not to hijack thread but what is your experience in being able to see fish in hard bottom areas? I do ok in soft bottom areas but hard bottom the brightness of returns makes it difficult. I've played with SI enhance settings but I seem to wash out image. Thx

Seeing fish echoes against a hard bottom is definately challenging ...

Sometimes backing the SI Sensitivity way down will help see the fish's shadow ...

I like seeing the shadows also. It helps me decide for sure that it is bigger fish that I am seeing and not just bait. Changing or using different color pallets helps some times as for as helping if it is real sunny or cloudy amber and green as well as others but I us blue most of the time. I use less distance(40' to60') on my 899 side image as it shows a bigger picture of what I am seeing. That is the reason to buy the biggest screen sonar that you can afford as the picture of fish will show up bigger also. Like I said I am just learning some of this sonar stuff.

I run an 899si also. I usually run at 70-80 side range. I like having that confirmation of "dots" in the water column to indicate fish.

Another question that I've wondered about: if running say at 80' range on SI in 20' of water am I really only seeing off to the side of lake bottom 60' since the water depth is 20'? Does that make sense...?

Rickie had a write up somewhere awhile back about what you are talking about.

SI range is slant range distance (using the Pythagorean theorem) ...

Ok that makes sense. Thx

455 kHz and 800 kHz are at different angles I believe the 455 covers the surface all the way out

Thanks for all this SI information. I just ordered a Helix 5 SI. Pretty small screen which reflects my wallet. Pretty excited to have this new tool.
