I'm off to pick up breakfast rnvinc, you guessed it,donuts.
I like it. I have noticed that stuff marked farther from the boat has a more accurate wpt than stuff marked close to boat. This is why I asked about the skew in the image without the water column. Just curious.
Sorry guys but I post on this board on the side and have an actual job that I have to do stuff at and so cannot always show up and comment quickly. At home this morning waiting for everyone else to get ready to go celebrate my Wife’s birthday, so I have a few minutes.
When you mark a waypoint you are saving a set of coordinates. These do not change with or without the Contour mode on. When marking a waypoint in Si there will be some differences due to the slant range versus the actual horizontal range. How much? It would depend on the distance of the object marked, the current water depth, the actual water depth of the object and I think the geography of the bottom itself. More things than the unit would know or could guess at. Most have found that waypoints marked in this way are close enough to find and fish the structure.
There is a split screen with Si and Di sonar already CP. I’m not sure how we would fill the water column area with the Di image unless you are meaning to essentially paste the Di image in the area (middle) of the Si image. I think that would make it very hard for most folks to understand what it is they are seeing then.
The arc is there is the Si beams. Remember that when looking from overhead; they are wide left-to-right but very narrow front-to-rear. There will still be an arc as shown in the drawing this arc represents the same slant range distance from the transducer.
mduncan62 what you say is correct:
“Even with the explanation of the contour lines, I don't find it to be that useful of a feature, as you basically have to hold your arm at a 45 degree angle and say it's 38ft down that way. It still seems to me that if you took the measurement from the contour mode, you'd get a much better measurement and then you could actually say, that hump or stump or whatever is x ft away from the boat on the bottom, and I'm in x feet of water, so if I cast x amount of feet and let it drop, my bait will go over the stump. As it is now, it still leaves a lot to the imagination, and being able to apply it into fishing would seem a little difficult to me.”
If the bottom of ever lake and river were perfectly flat (and therefore the water depth would be the same) than the Si Range lines while using the Contour mode would show the horizontal or “casting” distance to the object. However, since the water depth changes, the value of each of the Si Range lines changes as well and so there are no numbers shown when using the Contour mode. So you would still have to take an educated guess as to how far you would have to cast to fish that object.
Man, wish I would have gotten on here earlier. We have a place here in Eufaula that has some of the best donuts and sausage dogs… Mmmmm, those would have better than the bowl of cereal I ate!
Thanks for the follow up Greg. You are a valuable asset for this board. I had the little hostess donuts, in honor of the HB donut. :)
So, the markings further from the boat are more accurate then? Thanks Greg.
Like Greg stated if the bottom was flat you can formulate how far to cast and have the range easily. Problem is the bottom isn't flat in contour mode or straight up SI mode. I cast across points all the time, Retrieve uphill, downhill, fish ledges, humps etc etc so I don't think it's feasible to get a 100% accurate number to use the C2 = A2 + B2 formula. So they did the next best thing distance from the ducer. It's information you don't already have so any extra info is a plus. If you can see a shadow from a fish you can then get a good idea of how deep the fish is. I deep water spoon fish like this all the time. Once you get things straight in your head you can get an idea of how far to cast based on the range of your beams. It's gonna be good to have some more info (the contour lines) on the screen to try to be even more accurate.
Thanks TMike, Greg, Joby. Some people you just can't please no matter what. Reading this and other HB threads kind of reminds me when I decided to buy a homeless guy a hamburger and a bottle of water. Instead of being grateful that someone helped him for FREE, the homeless guy says to me, "where's the fries and apple pie?"
I wonder how many free enhancement downloads has Lowrance offered? How many of their employees monitor this board and others FOR FREE???
If you are reference me, I am asking intelligent questions instead of making snotty remarks about others comments. If not fine, if so well go pee up a rope.
Iceman and nymph, I'm happy with both units. Both units have free updates and upgrades. I guess asking legitimate questions, and wanting to actually understand what formula is being used to create the contour lines means something negative? Some, not all like to know more then look at the pictures on the screen. It's the useless ramblings of "how many free enhancements has Lowrance offered" that creates animosity. For the record, you can go to the Lowrance site and download the updates and enhancements for your Lowrance unit, same as HB.
Greg and Joby do a great job, it might be part of their job also, but they are appreciated. Mike and Doug, I have no idea, but both are sponsored by HB. You may have seen a guy with the name "Jason Gilstrap LOWRANCE" who represents Lowrance on C.Com. If you're going to trash talk, do a little homework first. If you own a unit from either brand and you aren't interested in knowing how it works, and what the features do and how they do them, I feel sorry for you.
Nice homeless joke, classy. Like CP said, well just read what he said.
