Fish Finder Training – Screenshots & Interpretations

[Feathers and Fins]

Nathan, Its the saltwater fisherman in me. The pic is a color break and to me that was GOLD any day of the week and three times on Sunday. A thermocline is the same Gold for open water fish. I run baits above and below them and they are highly productive just like ocean current breaks.

Short of a total bathometric survey of a lake and an angler willing to pay for that map I dont see sonars coming with that much details. A batho is expensive and I have been told from several people in the GIS field Beaver is going to be done soon. If the maps under 1000.00 I will get it. I use to have one for a smaller lake that was a gift from a buddy in GIS and the detail was unreal ( to the point the water didnt matter with that map in had )

Yea, that's what I have always seen in doing research(docs pic). But I guess if you crank up the sensitivity you would darken the area below that temp change? Try it sometime doc, see what happens.

I was just thinking more along the lines of taking the data from the sonar(2d, SI, and DI, and doing some programing, and then out comes a 3d representation. Not so much a map to download, but realtime data that would also show fish. The technology is there. I know it is. Not sure why its not being developed more finely than it is. It really is just like a camera, then taking those photo's and putting them together to make a virtual 3d picture. My wife has this app that she can take panoramic photos with by simply taking a photo, moving a little to the right, up, down, or left and taking another photo. The app takes the "image" looks it over and puts it together. There is some times that it gets the picture a little off, but what can you say for a cheap app.

Now take that, add some real tech geeks, and start making some true fish finders.

Keep us up to date if you hear anymore on that map.

Your almost talking about a google earth 3d and street view look. I know it can be possible but the expense involved being under water would be enormous and that would be passed on the the consumer and doubtful anyone would spend the thousands of dollars for a unit with that information.

[nathanhooper]

Yea, I don't want to drag it out anymore, but I guess I'm still not coming across clearly in what I have in-visioned. It would not be like a google earth view, it would be completely sonar imaging, which is under water, but stationary. It would be more like the batho, but real time and not based on GPS. But anyways. If I ever get smart enough to take the thoughts from my head and put them into a computer then maybe I'll buy everyone one of these new fish finders and then no fish in the lake will be safe...

I'm pretty sure they aleady have what you are talking about. It's used by the Navy. You and I just can't afford to put it on our boats unless we can somehow get some defense funding thrown our way.

[nathanhooper]

Hey, i got a question. Is it common practice to offset your sonar depth? I guess I have never thought of it, but it cannot be more than a foot or two off while sitting still or trolling right? Opinions?

[J-Doc]

I offset mine to measure depth from the keel at the stern. So if my graph says 1ft when I'm loading the boat, I know it's got 1ft between the keel and the ramp. Make sense? As for the trolling motor, I try to use keel depth as well so if I look at the front graph and the back graph, I hope they are within less than 1ft of each other but it doesn't matter up front as much as the keel I think.

So if I'm on plane and running, and my graph says 10ft, I get a bit cautious for underwater stumps and such.

[Feathers and Fins]

Yup I set mine so it is where the water level is on my boat +1 basically.

I wish Doc or I would have thought about it but we had a loon last weekend I showed him on side scan real time as it was swimming. This is another advantage to sidescann is being able to watch something moving around.

How do you pull pictures off a lowrance card after you saved to it?
