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

Jimmy, as soon as i find a dang boat im getting one of those. What kind of fun we could have with that!!!

Whoopee!!!!! I'm waiting; I'm waiting; the clock is ticking.

Did you get it yet?

Clear as mud! I understand but I just can't get used to reading those side ways images. Cool pictures!

Thanks, Ernest

JERRY JERRY JERRY....

Why are there two speeds and two depths displayed ?

thanks

Mo

The bow goes faster; the stern is trying to catch up.

You guys are making me learn too much.

The small speed is the average over a period of time. The clock shows the hour used. The SM is statute miles traveled and the speed is the average.

It also will display the water temp, air temp, time and barometric preassure.

HATER!!!!!

ok, I can now join in the discussion. After an easy 2 hour installation I finally have one. I have had mine on my boat for two days now. I have ran it about 12 hours total. No brush pile is safe anymore! After seeing Ernest and Guy showing all these awesome pics I just couldnt handle it anymore. It's just money anyway right? Even if I cant eat for the next week.

I'm working on an a b/p that is invisible to SI units. If I figure it out, I'll get rich off guides alone!

It is cheating IMHO. I say we all go back to flashers! I can read those better than a SI.

I'm also working on a bumper sticker that reads "real men like flashers"......

I'm not a crappie fisherman. I usually lurk around here, admiring the pics of the stringers you guys catch.

I've got to tell ya that the reply by Ernest Paty to the SI question went above and beyond to get a guy a little help w/ an answer.

Ernest, way to go, man. That is what we need more of on t his Forum, not guys publicly trashng other guys and bickering back & forth.

Thanks again, Ernest, that was 1st class!

-Alton

PS I don't crappie fish - I don't know any of the crappie guys - I've never met Ernest Paty.

I just thought that it was cool to see someone going above & beyond to help someone else.

I think this is wrong.

It's 17.5' wide Blue Area total (left side and right side) directly under the boat. So each side is (half that blue area which is called the Water Colume) so each side is water colume of 8.75' plus 41.25' of bottom contour side image for a toal of 50 feet. (Not 17.5' water colume out of each side. Just half of that out of each side.)

I think that is correct.

Good Job Ernest (Like I've said before, If you are half as good of fisherman as you are a teacher and you kept all the fish you caught, there would not be a single fish left on the planet. Thank God you don't keep them all.)
