Humminbird mapping cards for UB

[thebentpole]

I know this probably belongs on the Humminbird page, but thought I'd have a more targeted audience here...

What mapping cards are you guys using to get charts of the Upper Bay? Will I need a separate tidal card to go along with a Mid-Atlantic card (like my Garmins do)? Switching to Helix 9's

Thanks!

Following this too....looking for Lowrance map options here.

I have Navionics. It's ok. Pretty sure I verified that they're not that accurate. Especially out on the flats.

I run Navionics in my Humminbird, but with the tides and the flood waters. They aren’t going to be 100% accurate. .
