Johnson Outdoors keeps sports buffs from staying indoors. The company makes, markets, and sells camping and outdoor equipment (such as Eureka! tents and backpacks). It also focuses on supplying equipment for water activities with its diving gear (Scubapro and Uwatec masks, fins, snorkels, and tanks), trolling motors (Minn Kota), fishfinders (Humminbird), autopilot systems (Navicontrol), and watercraft (Old Town canoes, Necky kayaks). With GPS technologies and electric boat motors, Johnson Outdoors' marine electronics unit generates about 50% of the firm's sales. The Johnson family, including CEO Helen Johnson-Leipold, owns around 51% of the company.
