Took these with the Touch 7. White bass with crappie and smalllies mixed in. Still fine tuning, and I can not figure out interpreting side imaging to save my soul.

Next time slide the info on the right side off, get a full screen
Yeah I was trying to find them with side scan, but struggled and switched to downscan. Got these instead. Spotlocked over the top and it was game on.
Good pics,you must have been going slow,now show us your si in action
zummy...are you having trouble picking out fish and structure on the SI image...or are you having trouble visualizing how that SI image actually lays under the boat...??
Here's a short video I made that shows how the SI processor morphs the 3 dimensional underwater world into the 2 dimensional SI image...

Pretty much every aspect of SI I am struggling with. These are some I took 2 weeks ago.

Go SI full screen, it's working,
Make sure and raise the motor abit if it's in the way of the transducer.
Mark something," go to it".
Check it out on DI, you got it.
Ps , go left and right view full screen
Let's use this one as an example (but just speaking of the SI image side)...
http://i49.photobucket.com/albums/f2...ps79086d57.png
There are 2 side pointing SI beams (one pointing left 30° from horizontal...one pointing right 30° from horizontal)...
These sonar beams are very narrow front to back...but very wide top to bottom...(picture a Chinese folding fan opened upside down under your xducer...)
Each time the unit pings, the unit takes the echo information in that thin slice and plots that echo information on the SI image across the very top of the SI image in a thin line...1 pixel thick horizontally across the display...
The very next ping echo information is plotted at the top of that same SI image... Pushing the previous echo Information down on the image...into the "History"...or "what you have already passed over"...
It is this pinging, plotting, stacking (of the thin lines of echo information on the image) .... That builds the SI image on the screen...( it is not a camera snapshot of the bottom)...
It is very similar to how an MRI works...pictures of individual slices...and then those slices are stacked together by the processor to make a "compiled" image of the whole....
The vertical centerline is your boat's track...
Everything to the left of the centerline is being "pinged" by the "left pointing" SI sonar beam...
Everything to the right of the centerline is being "pinged" by the "right pointing" SI sonar beam..
The wide dark strip on each side of the centerline is the water column between your xducer and where that side's SI beam 1st contacts the bottom...
The wide lighter strips to the outside of the dark water column is the bottom detail from where that side's SI beam 1st contacts the bottom and continuing out thru the possible "reach" of that SI beams ping strength...(the ping is a sound pulse and it only carried out so far before it fades to nothing)...
Now...help me help you...which part of my gobbledygook can I break down into something that can help you...??

I was running along the dam of a small community lake and didn't see the need for it to be going 360 so I just ran it so it was looking out away from the dam.Quote:
