Helix side scan for beginner

I’m patiently waiting for the big brown truck to show up. I purchased the helix side scan with GPS. Any advice? Do I need to buy a SD card for it? If so what should I buy? Never had gps or side scan any tips would be appreciated!
Thank you!

Humminbird units use an SD Card (or micro SD Card depending on unit model) for saving Screenshots or for updating the unit software ...

What is the full model name of the unit ... ??
