Topic: helix 7 chirp si gps g2n compatibility with new my ultrex with mega di

[MM7966756]

I have a helix 7 si g2n. I recently got a mk ulterra that has the built in mega image di. Will I be able to use this? I understand it will not be mega imaging but will I not have si on this unit? Also what about the 2d sonar with chirp?

Depends on your Helix software version
ver 2.1 - I believe it's High Wide Chirp transducer and all is good
No SI but good 2D/temp and DI
