I am putting together the electronics for my new Canyon commuter. Any thoughts, recommendations, problems with CMAP same question for Navionics. Additionally, do I need a dual chip set-up(one for inshore to 40 miles out and one for offshore canyons) Is a chip nessecary for the canyons as all the canyons and outlines showup on the underlying map anyway, do i need the additional detail of the chip.
I think my choices are
Navionics $199 each
US674XL US800XL
or
CMAP C312 but I'm not sure of the second chip
