2D versus DI .....

[CrappiePappy]

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 .....

Never used the "beep" function, even when all I had was b/w 2d units. Never trusted the "fish ID" symbols to really show me that fish were present, after seeing them on the screen, even when I was sitting in 5fow and could see bottom. I think I may have seen "fish ID" icon(s) in about 3-4 instances where I actually caught a fish at that spot/depth. And I can't say that I EVER saw fish arches ... generally just using the units to show me depth & possible cover.

Once I got my DI unit and learned how to tweak it sufficiently for my purposes, and was able to easily identify exactly what was below me, the whole idea/need for 2d sonar went out the window. And I was not impressed, nor pleased, when my DI only unit was discontinued ... and 2d sonar was added back to it (under a new model name).

But, hey ... if it works for you, then good for you !! DI took the guesswork out of interpretation for me :
