Garmin's sales in the Fitness segment jumped by 79 percent to $150.7 million in the second quarter ended June 28 on the strength of its Vivofit fitness trackers, its lower-priced Forerunner watches and the new Edge 1000 cycling computer. This led the segment's operating margin to improve to 42 percent. With a turnover of $106.0 million, the Outdoor segment posted a slight decline in sales and margins in spite of the introduction of a new golf wristwatch, the Approach S6. With nearly flat sales in Automotive and Marine, the company's total net sales increased by 12 percent to $777.8 million, delivering an operating margin of 28 percent.
