Garmin offers an additional type of BlueChart cartography designed
for fishermen: bathymetric charts.
Our bathymetric charts include many details such as depth contours,
names of local canyons, wrecks, obstructions and more. Bathymetric
data is intended to be used as a fishing chart and is designed for
use in conjunction with our traditional BlueChart data.
Plan your next offshore fishing trip using bathymetric chart
data (unlocked by region) from Garmin's MapSource Americas
BlueChart v5.5 (or later versions) CD-ROM or sold separately on pre-programmed data cards. Use our bathymetric charts to find canyons and wrecks
before even leaving the dock to catch that big fish.
