Garmin’s gone after swimmers, runners, pilots and golfers with its specialty watch lineup, and now battlefield-trained agents are getting some attention from the global GPS giant as well. The company’s latest wrist-mounted machine is dubbed Tactix, and as you may have guessed from the design, it was “inspired by the requirements of law enforcement and police special operations.” There’s an altimeter, barometer and a 3-axis compass. US devices come preloaded with tide data (for amphibious wearers) and all watches include Jumpmaster software (for airborne use). It’s waterproof to 50 meters, has a night-vision-friendly green backlight and can track GPS coordinates for up to 50 hours on a single charge. It also functions as a boring ole wristwatch, with timer, stopwatch, world clock and alarm functionality. The Garmin Tactix, which ships in matte black, is expected in stores later this year for $450.
