HummingBird 7 SI Mega?

Is there such a thing? 9,10,12 cannot find 7..

Nope, the 5 and 7" are chirp. Mega ( large ) starts at 9.

what I thought.. I don't think I can get 9 or 10 on the dash my issue. Assuming Chirp and Mega there is difference? I.e. get the Mega?

I'm not happy with the 7 at all... They need to come up with a software upgrade even if you have to buy a different transducer.

Good input, i have Garmin on the front could go that way.. Still trying to figure out why they haven't incorporated the Navonics chip into there units. They own the sticking company..

The MEGA units CHIRP both 2D sonar and Imaging. You can choose single frequency or CHIRP.

MEGA is one of the three Imaging frequencies the MEGA SI and MEGA DI units have--1200 kHz or 1.2 MHz.
They also have 455 kHz, and 800 kHz Imaging.

Well is the 7 Chirp G2N worth it? I've got one no so far..

Id expect the new Humminbird graphs to be announced very soon......

Id hold off on getting a Helix 7.....

I want to clarify a few reasons I don't like the Helix 7. 1. Resolution is very bad and almost illegible on the si which is the reason I bought it. 2. Keys don't light up at night so you need to use a flashlight to figure out where the keys are in the dark.

Thx folks, appreciate the feedback
