This is what you see while running the unit. Top center is the boat location heading up. Everything below is behind the boat. Screen scrolls from the top down. The bottom of the screen is the furtherest behind. Whatever is shown in the dark blue area is directly below the boat. The lighter area is a birds eye view of the bottom out to the side.









This is the same image rotated and folded so it shows a better idea of the situation. The boat at top right, headed to the right with the blue area below and the lighter area out to the right side all the way to the creek bank. (The left side is hidden in this view.)

You very quickly adjust to the vertical format once you understand it. Also when you set the side scan to 50', for example, in 20' of water it will display 20' of blue + 30' of bottom for a total of 50'.

(Actually I turned the picture backwards accidentally but you get the idea)

Ernest you should get out of property managment and become a full time artist!!! Just kidding! You have a great gift for a explaining difficult things in a way that's easy for people to understand.

Cool site which talks and shows graphics as well.

What does the display look like if the boat is not moving?
Does a bridge column still look like a column or would it look like a wall ?

Cool man I need to get me one of those!!!

Ernest,
Great explaination. Now I understand. Thanks.

Ernest,

First, thanks for the succint explanation w/pics. I'm trying to fully understand so please bear with me. Secondly, I was reading the explanation one sentence at a time and then looking at the pic. I thought it was the left side and was glad to see your correction as I read further to confirm what I thought I was seeing.

Using the pic and the chart readings, the blue area is actually 17.5' wide directly under the boat and 31.5' to each side (49' - 17.5' = 31.5'). Since the ball of bait (?) and scattering of fish (lighter specs) are in the dark blue, it means the fish are in the 17.5 band of blue. Is this correct? It would also appear, two horizontal logs are on the bottom in this same blue area, however close to the edge of the 17.5' width. Right?

If I have this correct, it would also mean that the SI shows a much greater (understatement) area under the boat as compared to the traditional 2D units. At a depth 17.5', the 2D sonars would be showing basically 5-6 feet of area directly under the transducer. Again, is this correct? If so, WOW for the SI.

Am I understanding this correctly?

Thanks,

I get it....it's upside down and backwards.

ujc, correct except there's only one log under the boat, you are seeing both sides of it. Being close to the edge of the blue means they are close to the bottom. I something shows on one side only in the blue, it's close to the edge of the cone on that side. If it shows on both sides it's directly under the boat. Pretty cool huh?

Thanks to you, my wife prefers that I look at porn pictures on the net. She knows I would never pay for a prostitute, but she can't say the same thing about me buying a SI.

Thats funny!

It looked like the same log since the clarity wasn't quite the same. Yes, it makes sense and it is COOL.

Oh, $#^@, I just realize what you mean by the edge of the blue being the bottom. That means the ball of fish (@ bottome of pic) are on the bottom to about 5' off the bottom.

Thanks for the confirmation and correction.

Beautiful explaination.

Thanks Ernest!

Regards,
Jason
