Chirp or Non Chirp

In order to get CHIRP in a Humminbird Helix, the Helix 12 is the only unit that offers a chirp version. Quite a bit of coin to get chirp.

I recently bought a Garmin Stryker 7 SV with Chirp. The 2D is amazing at showing fish. The DI and SI has better target separation than I was expecting. I can now tell a school of fish from a school of shad because you can see individual fish in the school.

LOZ,BEFORE THESE UNITS HAD CHIRP ,DI ANS SI WOULD SHOW INDIVIUAL FISH IN A SCHOOL,HAVE 859 AND 1199 AND THEY DO NOT HAVE CHIRP YET I CAN SEE INDIVIUAL CRAPPIES AND CAN TELL ABOUT THE SIZE OF THEM

Has anyone seen a comparison SI/DI chirp to non-chirp? If so, could someone post a link. All I ever see is 2D which looks great! If chirp is so good in SI/DI why are they not pushing it more?

I ALSO HAVE ELITE 7 DI WITH CHIRP,I CAN NOT SEE ANY DIFFERENT ON DI,NOT IN MY THINKING ANYWAY

I hope H'bird puts CHIRP in their under 9" models.

Here's a picture of 4 ping pong balls,that are tied on a line,about 5 inches apart.I really don't see were chirping di would help the separation get any better on di.

Thanks for the replies. It is a lot of information to digest and make a good choice for the buck.
