After a brief wait, Epson's first batch of fitness trackers is reaching the US. To get things started, it's launching a new golf swing analyzer (the not so elegantly titled M-Tracer MT500GTII, below) that attaches to your club's grip and sends real-time feedback to your phone, ranging from the swing path to the ball impact. It'll arrive in stores in March for $299. The company's Runsense GPS watches are coming along for the ride, although you won't have the option of the basic SF-310 that launched in the UK. Instead, you'll have to consider the stride-tracking SF-510, altitude-aware SF-710 and heart rate monitor-equipped SF-810 (above) when the lineup ships sometime in the second quarter of the year. With prices between $250 and $350, they're squarely in competition with watches from the likes of Garmin and TomTom -- you'll want to comparison shop before you commit to buying sport-minded wristwear.
