This is why I believe SI is king.......With SI, you know where the fish or other structure actually is........ You may miss it on 2D......With DI, you see it, but the range side to side is pretty large and you don't know where it's at ..... With SI, you can narrow the range to get a good look and know exactly where it is.Quote:

This article must have been before HB announced the 360, since there was only mention of the Furino Omni?Quote:

I just read what I just posted and I'm not your if I understand it:Rofl
Happens to me all the time....:biggrinQuote:

That would preclude choice #1 ... so #2 wins by default.

How about an answer #3 than?
(3) the sonar signal from the transducer does reflect off of objects close to a sharp drop, but the control head that the transducer is connected to, does not display them due to user controlled settings (such as Bottom Black in the Matrix 67 unit) or because the stronger signal strength of the sloped bottom is overpowering them.
By “overpowering” I am meaning that the unit can only display one color for each pixel in the display and it is programmed to display the strongest sonar signal returned to it. So the weaker returned signal from the object does not get displayed.
- Having said that; if the sloped bottom were very soft and did not reflect a lot of sonar while the object was very hard and reflected a lot of sonar: you would see a stronger signal within the sloped bottom. But most would just assume that this was a part of the drop.
I woulda said that ..... but it was just too obvious....:biggrin
:ThumbsUp Thanks for another educated perspective Greg.
