Ideas about Helix 7 g4 and g3n

[Edwardbowen]

I have a helix 7 G4 with SI, chirp and is 1024 x 600v and I am looking to replace with helix 7 G3N
Mega Di,SI and chirp and 480v x 800H.
Is it worth going with the 3gn and less resolution but have Mega SI and Mega DI
Or should I keep the G4 with si and higher resolution. My console is a G4 Mega Si and Di so no matter what I cannot network. Any suggestions?

The G4 and G4N Helix 7 SI models are MEGA SI and have the same transducer as the G3/G3N Helix 7 MEGA SI units.

AND no Helix 7 SI model has true Down Imaging. They have composite DI views created by blending the two SI pulses==the same thing as all the number series SI units and first generation Helix SI units in all sizes.

Thanks Wayne. I guess what I am asking is, now I have helix 7 with SI ( Not Mega Side imaging) G4 on the bow and I picked up a Helix 7 with MEGA SI (3gn) to replace it. The resolution on the g4 is 1024H x 600v and the g3n is 480v x 800h. I am wondering if it is worth replacing the Si with msi.
I haven't opened the G3N yet and now I am having 2nd thoughts.
