Re: Lowrance Structure Scan Questions

OK, thanks for the help. To me, it looks like there is a "light source" coming from the top, but I frequently have problems interpreting 3D information displayed in a 2D format. I guess I am defective.

Re: Lowrance Structure Scan Questions

No problem.

Regrettably, I need apprise you that there is no directional source of illumination. Lowrance does not make an entity with said functionality unless it is an imperfection isolated to mine. Alternatively your fallible observation could be ascribed to the hues on the screen itself…darker at the top, lighter at the bottom.

Stated otherwise and without the help of MicroSoft Word Synonym, there aint no fucking directional light source other than the flashlight hitting the wall through ones ears.

Re: Lowrance Structure Scan Questions

That is some neat stuff right there. Ditto thanks to Setthehook for posting the tutorial.

One question I have. I have noticed that the gradients are illuminated by an imaginary light source coming from a rather acute angle. Can that angle be shifted to a different position to help clarify minor features of the topography? For example, it looks like the light is coming from low on the horizon and to the top of the screen pics you captured, could it be rotated to come from the bottom or side of the image?

Thanks, setthehook! That technology is amazing.....................just not what I was hoping it would be. Thanks a bunch for taking the time to post those pics! I appreciate you help.

Re: Lowrance Structure Scan Questions

Here is an example. Pics are blury but I could not find my SD card, had to take a pic with my cheap camera. The first pic shows Structure Map layed over a Navonics map. Things I dont like are the overlap caused when I went back and forth. When going in a straight line you dont get overlap and the overlaped area is darker...harder to see through. I also dont like the centerline (directly below the boat, it is misleading)

Second pic is the same pic with my edits and the things I do like. I can see the break is partially where the map shows (longer red line). It also shows boulders on one edge of the cut (red circles).

Re: Lowrance Structure Scan Questions

Agree. If you are looking for actual depth lines (not what Nav thinks) then Dr Depth is the best I know of. If you want a view of what is below the boat (tree to the right, rock to the left and be able to GPS them) then Structure Map is the best. Keep in mind and from my time with the Gen 2 stuff, Structure Map lays a picture of rock/trees (structure) on top of the Nav does not redraw or create the gradient map.

A point of clarification, Structure Scan is different than Structure Map. Scan is this, (first 7 screen pics).

Map takes the Scan view and lays it on top of the map that is on your Lowrance. (next two pics)

Re: Lowrance Structure Scan Questions

Thanks for all the replies so far! I'm looking for contours under water much more than the gps location on a tree and such. I have researched the Lowrance option more and it appears that the detail of the map is dictated by Navionics or Insight etc. I don't want those maps to be my contour map - they don't show what I want to see on the waters I fish.

I think I'll go ahead and make a doctor appointment. After a closer look, it appears that Dr. Depth is the only real option for what I want to do.

Re: Lowrance Structure Scan Questions

I have a hard enough time distinguishing what I see DIRECTLY below the boat..... You want Me to look sideways, too?
Sructure scan sounds cool, I don't think I'd ever use it.
