Helix training videos or resources?

I have a trip scheduled with Slade at the end of the Month...between now and then I'd like to educate my self as much as possible on and off the water....any recommendations would be appreciated Thanks.

This is a good video. It is a sonar interpretation video that is optimized for the Humminbird Helix.
He also sells a quick reference card that is handy.
