Thread: Humminbird New Features for 2011

There are four new software features in the Side Imaging Units for 2011. They are:

* Contour / Terrain Mode
* SI Navigation
* Down Imaging Zoom
* Side Imaging Range Lines

These features are in the 2011 798ci SI HD, 898cSI, 998c SI and 1198c SI models. Software upgrades for previous side imaging units (1197,997,987 and 798). The 797 and 981 will not get these software upgrades due to limitations in the units.

Contour Modes:
With Contour Mode OFF the water column is shown as it has been since we first came out with SI. Showing the water column can be valuable as it shows suspended fish and great shots of structure near or under the boat; however, the display of the water column can be confusing to some

OFF:



ON:



OFF:



ON:



SI Range Lines:
The SI Range Lines can be turned OFF or ON from a setting under the SONAR tab. The Range Lines give the user a quick reference of how far objects are away from the boat.



Side Imaging Navigation:
When you are Navigating (GOTO) to a waypoint NOTE the boat icon on top of the side imaging screen will point to the direction of the waypoint. This icon will move around to provide the direction to the waypoint.



Down Imaging Zoom:
New Software Feature. Ability to Zoom in on DI

Just a question on the range lines. It appears that the water depth, plus an additional 9ft on either side are added into the first depth line. So the building on the right side of the boat on the 75ft line would actually more like 38ft away from the boat if my math is correct. That's a pretty large margin of error, in my opinion. If I'm reading this wrong, please let me know. For guys the scan on lake like Stockton in 50 -70ft of water the error would be even more. Seems like it would be pretty easy to subtract the depth out of the range calculation, so that it would at least be within 9 ft.

WOW, I have to agree with what was said here and am awaiting a professional answer??????

I bet they are filling in the water column with down imaging, so no error. SWAGGING.

I think the water depth is shown as wide as it is deep but with the boat in the middle it would be 14ft. on each side of boat. That would make the bottum line to the 37 mark 23ft. But the 37 line is the same distance from the boat as the 37 line is from the 75ft. line. I think were missing something here on the water column width.

Even if it's just the depth, in 30-50ft of water the measurement is going to be off by the amount of water depth. That renders is pretty useless, unless you want to sit and have to adjust by doing the math in your head to get an idea where things really are.

I am no expert on this heck I dont even own one yet but will. I am just guessing here but, is it because there are two different distances here. Well I dont know how to say what I want. One being the depth is straight down and the other measurements are to the left and right or horziantal arcoss the water. Meaning that the Buildng is 75 feet to the right of the boat, so a person needs to go that distance and then go down with the depth reading. If that is the case you wouldnt really be able to read the graph literally and just make take it that the SI adjusted the image.

Or maybe I am totally wrong and the building is 75 feet from the boat at a direct line from the boat at an angle.

Heck I dont know, I am just reading up on these because I will have one before spring and what to have some Idea on how it works and how to read it.

Thanks

They doing something magic, but I like it.
