Helix questions

[bangbang]

I am converting to humminbird and I have a few questions before I buy 2 9" units. I plan on getting the helix 9 mega SI for my console and networking it to a bow unit. The bow unit's transducer is the us2 on the ultrex, I want the unit to have its own gps and the ability to use the DI off the console unit. There are many options, which one will fit my need?

thanks

Helix 9 CHIRP GPS G2N

Helix 9 Sonar GPS

The G2N would be the best one since it has CHIRP sonar.
