Sound about right Rickie?
Correct ....

Let's get some more info to see what we can set up ...

I think I understand there is the HDSI and an additional 2d xducer attached to the transom and both connected to the 998 (with the HB TS3 Switch) ...

1. Where is the 998 going to be after adding the HELIX ...??

2. Where is the Helix unit going to be ...??

3. Will there be a unit at the bow ...??
