But you get 60' of the upper 10 feet. Right?

Forgive me.. I'm on midnights and my brain doesn't function well on nightshift...

Can you explain the question a little more..??

To get 60ft of linear bottom to show on the screen.. Set the SI Range setting to an equation of "60 + water depth"...

If the water depth is 10ft... The SI Range setting should need be set at 70ft to show 60ft of linear distance bottom...
Because the first 10ft of the linear "70ft SI Range" setting is the 10ft of water column...

An extreme example (but still true) would be...

If the SI Range setting is 60ft (left and right)...and..
If the water is 50ft deep...

Only 10ft of linear bottom would be showing (left and right)....

Because the first 50 linear feet of the 60ft SI Range setting is 50ft of water column...

Thanks guys,that was great information

This is all very helpful for first time si guys. keep it coming.

If I understand this right, If straight under boat bottom is 20 feet and SI is on 50 ,then 30 feet of SI is really all I see because the rest would be off screen? hope I am not making you upset,just slow at learning anything thats computerize. THANKS. As I see it now ,its like in a house and measuring the wall to the floor, then measure the floor andif room is 20 feet and wall is 10 feet , I would need SI set 30 feet to reach other wall?

I think you are getting it...

The SI Range setting has been misconstrued by HB customers from the very beginning of SI's introduction into the marketplace...

The confusion is understandable because the HB advertisement says ..."480ft of bottom coverage can be seen with the HB SI"....so people just automatically think that the HB "SI Range" setting is what gives this advertisement of 480ft...

In reality... The "SI Range" setting is an equation of 2 separate linear distances added together...

The first linear distance is the water column...(depth of water in ft)..
The second linear distance starts at the point where the SI beam first contacts the bottom (straight down) and reaches out along the bottom until the remainder of the SI Range setting is reached...

An easier way to see this SI Range setting equation is turn on the "Range Lines" in the main menu...(I think its under the sonar tab in the latest software update)...

As soon as the "Range Lines" are turned on (in the SI View)... The actual water depth your boat is currently in will be displayed on the SI image at the exact point where the "dark blue water column" touches the "lighter blue bottom"...

This is because SI Range setting first measures straight down ... and then continues measuring out to the sides until the SI Range setting is reached...

Rickie, I really thank you, i would have never figured that out,I am glad this board have people like you with knowledge that is willing to help us that are struggling and it has been many on this board and so I want to thank all of you
