Question for a friend

[Snarf]

My buddy has a Hummingbird Helix 9 DI GPS G2N CHIRP and the Trans he has is a XNT 9 DI.

First, although I've tried to convert him to my bass world he's a jet boat guy chasing kokes and walleye. Still a good time as long as you're on the water . I don't have humming birds not that I would be the greatest help to him anyhow; I have a hard time making sure my graphs are doing everything I want them too. Here are a few things we are wondering...

In the Advanced setting what transducer do we select since we cannot locate this one.
Fishing regularly deeper depths than me (30-50) foot range what Hz should he set his Sonar and DI each too.

These are the two main things i'm wondering before we take his boat out and make sure everything is working right.

Thanks for the help

The default transducer setting matches that transducer, you do not change it unless you purchase a different transducer.

The XNT 9 DI T is DI 200/455 kHz.
