Golf clubs are the tools we use to strike the golf ball. A golf club has three components — lub taub hau, ncej thiab tuav. The txoj cai ntawm golf constrain golf club designs, but the goal of clubmakers is to create golf clubs, within those constraints that maximize the physics behind a golfer's swing while allowing for some range of swing error to provide an accurate, long, and forgiving shot. The better your swing, the less forgiving club you require whereas the more your swing needs work, the better off you are with a more forgiving club design.
Cov txheej txheem niaj hnub ntawm cov koom haum ntaus golf feem ntau muaj peb ntoo (tus tsav tsheb 1, 3, thiab 5), yam tsawg kawg yog 1 hybrid (3H) xya hlau (4, 5, 6, 7, 8, 9, thiab PW), thiab ib putter. Qhov no muab rau koj tag nrho ntawm kaum ob lub club. Cov kev cai ntawm kev ntaus golf tso cai rau koj nqa kaum plaub lub koom haum hauv koj lub hnab, yog li ntau tus neeg ntaus golf ntxiv lwm qhov sib txawv lossis tshwj xeeb hybrid. Tom qab tag nrho, ntau cov cuab yeej peb muaj nyob rau hauv peb lub thawv, ntau txoj kev xaiv koj yuav tsum ua kom koj txoj hauj lwm yooj yim dua!

Woods are used to hit long shots. If a golf hole is 450 yards from tee to green, most golfers use a wood to hit off the tee. A wood is a hollow-bodied large headed golf club. It's customary to use your woods when you are 175 yards or more away from the green.
The tus tsav tsheb (also called the 1 txua) muaj qhov qis tshaj plaws ntawm txhua lub club golf. Loft yog lub kaum sab xis ntawm lub ntsej muag lub ntsej muag uas tswj kev sib tw thiab cuam tshuam kev deb. Tus neeg tsav tsheb muaj qhov siab ntawm 7 thiab 12 degrees. Cov neeg ntaus golf uas muaj kev paub dhau los tau ib txwm nyiam cov neeg tsav tsheb qis dua (tsawg dua 10 degrees ntawm loft), uas yuav tsum muaj kev txawj ntau dua los ntaus dua cov tsav tsheb siab dua.
A dramatic development has occurred over the past several years — professional golfers are throwing out their low lofted drivers and opting for large-headed, higher-lofted 10 and 11 degree drivers. Their argument is that the longest drives are achieved by combining a high launch angle with lower spin. This change is a huge reversal from prior years. During the mid to late 1990's, the average loft on the PGA Tour was around 7 degrees. However, those were difficult shots for the pros to make and the low loft resulted in lots of spin on the ball. The experts in ball flight analysis showed that the longest golf drives are achieved with a high launch angle combined with low spin. The new solid core golf balls provide that low spin which was not available in the golf balls of yesterday. A higher lofted club gives the golfer the higher launch angle.
Feem ntau PGA pros tam sim no nqa cov tsav tsheb nrog lofts ntawm 8.5 txog 10 degrees lossis ntau dua. Tsis yog-pros yuav tsum tau ua si tsav tsheb nrog nqa 10 degrees lossis siab dua. Yog li, peb cov lus pom zoo yog: ua raws li cov lus qhia ntawm PGA pros thiab ua kom lub siab ntawm koj tus neeg tsav tsheb.
Most golfers also carry 3 and 5 loj in their bag. A 3 wood has a loft between 15 and 18 degrees, and a 5 wood has a loft between 20 and 22 degrees. The higher the golf club number, the higher the loft. Also, the higher the golf club number, the shorter the club shaft length. The 3 wood and 5 wood are commonly referred to as ntoo fairway, because they are most often used during the second shot of play, when you are supposed to be in the fairway of the golf hole (as opposed to in the woods!). All higher lofted woods (7, 9, 11, and so on) are commonly referred to as siv ntoo. A 3 wood is generally ½" shorter than a driver and so on with each successive club. However, we build all our woods higher than a 5 wood the same length as the 5 wood. This is because shortening a club decreases the arc of the swing. The smaller the arc, the less speed the golf club will have when it strikes the ball — ergo the less distance the ball will travel. We believe that a 5 wood is short enough and while the 7 and 9 zoo provide more forgiveness, we also want longer distance in our shots. Arghh, the physics of golf!
What about 2 and 4 loj? Cov ntoo no yeej muaj nyob thiab tau nrov 20 lossis ntau xyoo dhau los, tab sis lawv tau poob tawm ntawm kev nyiam vim tias cov thev naus laus zis tshiab tau txhim kho kev ua haujlwm ntawm ntoo. Niaj hnub no, cov golfers feem ntau nyiam 7 thiab 9 ntoo hauv lawv lub hnab (uas tuaj yeem muaj kaum plaub lub club nkaus xwb) dua li 2 lossis 4 ntoo. Qhov tseeb, tam sim no muaj ib txoj hauv kev los suav nrog cov ntoo ntau dua thiab tshem tawm cov tsoos tsis tshua muaj lej hauv koj cov koom haum ntaus golf. Qhov ntawd yuav tau tham ntau dua thaum peb tham txog cov hlau.
Why aren't woods made of wood? They used to be, but since the 1980's woods have been made of metal. Metal has many advantages over wood. For the beginning golfer, the most important features are perimeter qhov hnyav and qis nruab nrab ntawm lub ntiajteb txawj nqus (LCG) which can only be achieved through precisely molded metal. Both of these design technologies result in golf clubs that are much more forgiving than wooden woods. Perimeter weighting helps create a larger qab zib — a larger area on the face of the club that will result in a good hit. Low center of gravity creates mass at the right place — increasing the height that the ball will launch off the club and reducing the likelihood of miss-hits into the ground.
