which is the best to use and why?
Bow or console? How are you fishing?
My vote would be for DI ... given a head to head comparison.
Main reason being that the DI "picture image" is going to tell you a lot more about what's under you, than the best 2d "finger painting" image could ever hope to show.
Being able to look at your screen and see images like these :
Attachment 194794
Attachment 194795
... and know what they are the instance they appear on the screen, and not have to guess or spend a lot of time going through the learning curve of interpreting the shapes & colors of the blobs that 2d produces ... is just a no-brainer IMHO. :twocents
... cp :kewl
If moving I would say DI, but sitting still it would probably be 2D or a split screen
I fish from the bow but the screen is at the back of the boat. I have a small jon boat and can see it from anywhere. it is mounted on a ram mount and I just turn the screen to wherever I am sitting at the time.
thanks to all. the di does give a very good picture and I have trouble interpreting the 2d.
Post some of your 2d images and we will help you understand ...Quote:

going out tomorrow and will take a few for posting as you suggest. thanks, just learning.Quote:

I am very fortunate to live close to a TWRA lake that has thousands of crappie in it along with catfish...bluegill, hybrids and largemouth. I go to that lake just to get experience in trying to tell what kind of fish I am seeing. Catfish give off a somewhat unique signature as do crappie. Bluegill will just be small specs on the di.Quote:

Di is better for seeing structure.
If moving a lil faster, you might not even see fish on Di or they will be a tiny dot. The pics above the boat is moving slow (drifting) so the Di images are stretched a bit
I use both togeter in a split screen. Mainly look at the 2d and use to Di to see if that blob is fish or brush.

Crappie with a big fish next to a log.

Nice school of Crappie

For a few dollars more you can have 2d, Down or Side image and not be upgrading later. I would even go with a smaller screen if need be. With the smaller screen you can reduce the distance out to the sides to improve the image or use only out one side. Yes bigger is better just go with the best Side image you can afford. I put the HB down image on my trolling motor and wish I had spent the extra buck for Side image.
I have a lowrance hds7 gen 2 touch. it has it all, but I am new to the technology and haven't learned to read the graphs yet.
thanks for all the input and pictures. have been out of pocket and not fished again yet, but will post pictures for more input soon.

Both. They made them for the unit for a reason. Each has it's own merits. Together they are formidable at finding structure and fish. I always refer to the DI and then when I see structure I watch my 2D for arches. Simple.
This is what I have so far.Quote:

That 2d overlay just seems to gob up the DI screen to the point of chaos & confusion.
Just sayin :twocents

actually, that is kind of what I am leaning toward unless somebody really has some good reasons to do otherwise. one of my biggest concerns is to learn how to fine tune so both the SI and the DI are crisper. any suggestions are certainly welcome.
I agree with Pappy ...turn off the 2d overlay and run 2d in a separate panel ...
Then you can compare targets in each sonar format ... 2d - DI - SI ...
When a target enters the right edge of the 2d or the DI image ...that same target should enter the top of the SI image ...
Lots of jumbled echo masses on the 2d or DI image can be masses of fish, baitballs, or brush ... This is where the SI image should help distinguish what the 2d and DI are showing ...
Anytime you see a target that looks like an individual smear ... It's a target that happened to get "pinged" multiple times ...either by the boat and the target not moving ... Or by the target moving with the boat ...
Either way that target was in the beam long enough to get "pinged" multiple times ...

thanks all. I hope to go out tomorrow and am going to set up a SI/ DI blue and run that and ditch the 2D sonar and see what I find.
I like to run 2d and ds side by side, I also overlay the ds just a little. Also it seems I like to run my contrast lower than a lot of people. Mine is usually in the 50-65 range and will change depending on what. color pallet I'm running.
The best advice I got on depth finders when I started was to get on the water and use it, push buttons and see what changes it makes. If you screw it up you can always go back th the factory default settings.
I like that Justin. just haven't put in enough time yet, but now that the weather is better, I m going to get with the program. am now retired, so I can go out more :biggrin
