Garmin Approach S6 Golf GPS Watch - Garmin's Most Advanced GPS Golf Watch! (Black) he Garmin S6 may be Garmin's lightest, thinnest golf watch, but it comes preloaded it with more than 30,000 international courses  without extra fees or paid subscriptions. In addition, you'll be able to download free course updates whenever they become available. One glance at your Garmin Approach S6 watch, from any point on the course is all it takes to get yardages to the front, back and middle of greens with clear, easy-to-read numbering. Garmin's amazing 'SwingTempo' feature measures your backswing compared to your downswing times and expresses this in a ratio. According to studies of successful golf swings this ratio should be 3:1 - your personal SwingTempo shows you where you stand compared to the optimal ratio. The 'SwingStrength' feature allows you to compare how hard you swing with your normal full swing. Save a great shot then measure your next shot or swing against this shot during practice. This way you can train yourself to swing more consistently. There's no need for subscription fees, costly downloads or additional set up charges. The Approach S6 comes with FREE lifetime course updates The Approach S6 Golf GPS Unit is fully compatible with Garmin's amazing Garmin Connect community, so you can play, share and compare your game and scores with other golfers. Download your round and contrast it to your last round, track improvements to your handicap for every course you play. The Garmin S6 also lets you manually position pins, get distances to doglegs and layups, customise yardage points (mark bunkers and water hazards), and print digital scorecards for Stroke Play. A dedicated 'GreenView' button takes you to the GreenView screen in 1 push, no more scrolling through the menu. GreenView gives you the true shape from wherever you are on the course, even if you're behind it. The 'CourseView' function gives you full colour hole-by-hole details for more than 30,000 golf courses, even before you play them. Preview doglegs, hazards and green shapes from wherever you are on the course, or even from home. Never miss another text, email or even an alert from your favourite social media feeds just because your smartphone is in the cart (or deep in your bag). S6 acts as a wireless extension of your Apple iPhone device (iPhone 4s or newer with iOS7 installed), displaying whatever your phone does, right on your watch. Now you can read that email or text you've been waiting for wirelessly  even in the middle of the fairway. The Garmin S6 GPS watch uses a rechargeable lithium-ion battery which gives up to 10 hours in full GPS and 12 weeks in watch mode before the lithium-ion battery needs to be recharged.
