I have a buddy that is looking at getting a new depth finder. He is looking at the Helix 5 DI / GPS and The Helix 7 MEGA DI (G3) / GPS. I told him that I have the Helix 5 DI/GPS and the Helix 7 Mega DI/Mega SI /GPS and that the DI on my 5 is better than the DI on my 7. What are you guys/gals opinions?
Thanks for any feedback.
Get the 7. Screen size is worth it.Quote:

Thus the HELIX 5 DI data is coming from “straight down” - - whereas the HELIX 7 MEGA DI/SI data is coming from the sides ...

Now that is your scenario of why the HELIX 5 DI has better DI than your HELIX MEGA DI/SI ...
You mention your buddy is considering the HELIX 5 DI or the HELIX 7 MEGA DI - both have a dedicated DI piezo so the DI image should be similar (except HELIX 7 MEGA DI also has the MEGA 1200kHz frequency choice that the HELIX 5 DI does not) ...

I don't think so, but I will check. Thanks for the input.Quote:
