Sonar Lifts Garmin Marine Sales 16% and Nearly Doubles Segment Profit

Garmin's Marine segment grew 16% to $309.9 million in the third quarter, led by sonar, in the same quarter it launched LiveScope 2 and ran a 30% operating margin. The tournament fight over forward-facing sonar has not dented buying, and may be helping it, since every proposed ban tells weekend anglers which tool the pros think wins. Garmin now has more to fear from a rulebook than from any rival screen.
