Humminbird Cartography

Get advice the locals won't give you with a Humminbird® SmartStrike™ map card. Based on search parameters like season, time of day, temperature and fish species, SmartStrike highlights areas of the lake map where fish are most likely to be biting-before you even wet a line. No more guessing or wasted casting. Just fishing. Exclusive to Humminbird LakeMaster® High-Definition inland freshwater systems, and compatible with the Humminbird ONIX® and ION™ Series, and select HELIX™ Series models in March 2016 (software update required).
