Callaway Golf has introduced the Allsport watch, which the company describes as the first multi-sport watch designed specifically for golfers. The Allsport incorporates popular features of fitness tracking devices into a conventional GPS watch, including a calorie tracker, a step counter and multi-sport training features suitable for other sports, including cycling, running and swimming. As for golf, the GPS-enabled watch offers yardages to the front, middle and back of greens on more than 30,000 pre-loaded courses. It also measures the shot distance and charts the player's total shots with a scorecard tracker. The Allsport's battery, which can be recharged via a magnetic charger, is said to last for 8 to 12 hours. The Allsport can be synchronized via Bluetooth to the free Callaway smartphone app, which enables reception of calls, text and email notifications directly to the device.
