SmartStrike is a family of map cards that parallels the standard Humminbird LakeMaster editions. Coverage area and lake lists remain the same and both are compatible with all LakeMaster compatible products. The difference is that when a SmartStrike card is used in a HELIX 12, 10 and 9, HELIX 7 G2 and G2N modes along with all SOLIX, ONIX, ION Series units, it has the special capability of using the contour Elite search functions on (and only on) any of the high definition lake maps for that card. It's like looking into a digital crystal ball. SmartStrike also brings the groundbreaking technology of follow the contour to your fingertips. When combined with a compatible i-Pilot Link system, your map card allows your boat to automatically follow a path directly on or offset from any contour, so you can focus on fishing.i-Pilot Link compatibleEasy to read contoursDepth highlight rangeWater level offsetShallow water highlightScrollable lake list
