2D versus DI .....

[Snuffy115]

Every tool has it's uses. 2D sonar is best when it comes to finding fish under your boat but it doesn't show the structure and bottom detail that fish use as their habitat very well. DI/SI is best at revealing that structure and makeup of the bottom. It does show fish, as little blips, but it can be difficult to distinguish them.
Just because there's no fish there now doesn't mean they will not be there at another time. If you know the makeup of the bottom, where the structure is, and the behaviors of the target fish species, all these tools will help you catch more fish.

I will have to try that contrast setting on my garmin. I bought my sonar all excited about DI and side imaging, but now use 2D 95% of the time. Do love side imaging to see bluegill spawning though. I get that i can see a nice tree on DI, but when i see the fish arches on 2D my confidence goes up

When I see the white dots on my DI my confidence goes up, if your not seeing crappie on your DI something is wrong.

2D will show a lot of stuff as arches, which is not fish.

It is mainly inexperience and no patience to learn on my part. I see all kinds of dots on DI at times...some go away depending on settings and frequency. I dont know which ones are fish right now. I need to play more with contrast and experiment with it all. Just so little time to fish i hate to play with sonar. I have never looked on DI and seen something i was sure was a fish...except on other peoples screenshots here occasionally

Spend some time watching YouTube videos on what fish look like, what shad look like, etc. The 30 minutes it will take you to learn will save you hours of time fishing in unproductive areas. Di is not rocket science. It will take you the longest to guess what size/type of fish it is you are looking at. Their size on the screen will change some depending on how zoomed in the screen is (10 ft of water vs 30 ft of water). White bass are the hardest to tell from crappie until you drop in and see what bites. It is easy to tell a big gar or catfish though.

Most of the major electronics companies will recommend that you turn off the "Fish ID" on their units. The problem with this feature is that it cannot differentiate between fish and floating vegetation or debris - sometimes. This is why you might want to learn what a fish looks like via arch interpretation. Much more reliable as to positive fish location, using 2D. This is what the pros do as well. JMO.

So none of yawl like to hear all that beeping ........I think the show is called tuna wars .....They use it .....
I kinda thought some folks wouldn't like this post ....but after looking at graphs of every possible design for 45 years ...yes EVEN the ole paper units ....AND ....up to 3500 dollar big screen units they just made this year .....I am still sticking to that's a fish and it's on something ......
The main point of the post is you can use 2D and do very well with it , mine don't tell stories ....if it goes to beeping and a bunch a lil blue fish show up .....I typically go to Ketchn ....when it gets quiet and the blue fish leave so does the bite ....
Simplicity at its best .....

I like simple and your solution is simple, it catches fish. I run 2d and di side by side to get the benefits of both.

Its acording to what lake you are on.Just 2d on KY lake,and I would be in trouble.si and di are great here,without them I would catch alot less fish.The thing is spending the time to learn how to effectively use them,ive probally side scanned 60 hrs total this year and have marked alot of structure.
