I came from the HELIX mega my SI and DI was nothing short of astounding. I decided to go to 7612s and I cannot believe how terrible my SI and DI are. It looks like the traditional 2d is on par or better than the HELIX. But looking at my side imaging makes me want to cry compared to the much cheaper HELIX units. Is it possible that my units need to be updated or something? I set up my transducer in the same manner as the Humminbird units.
