I got a Helix 12 and a 10 for Christmas.. Wondering..what comes preloaded on them for mapping? and If I’m traveling the country is the Navionics+ a good card to get? Will it do autochart live or do I need to get the chip from Humminbird to do that? I know there is up to 8 hours just on the machine I can use. Any help would be great!
Helix units and mapping…
