Golf drivers help you achieve distance and flight off the tee. You can select from standard, midsize and oversized clubheads and a variety of materials, from innovative titanium to popular aluminum. Today’s larger clubfaces have larger sweet spots and promote greater stability and power on impact. In addition, drivers come in many lofts, typically between 8 and 15 degrees for men and 10 and 15 degrees for women.
Rangefinders allow a golfer to measure exact distance to the hole from their current position; they are illegal according to Rule 14-3 of the rules of golf, but the USGA allows individual course clubs to institute a local rule permitting rangefinders, and they are common among recreational golfers. The typical rangefinder is an optical device that is aimed by sighting the scope on the flag and using the calibrated gauge in the optics to estimate the distance based on the flagstick's apparent height. Other rangefinders estimate range using a calibrated focus or parallax control; the user sights the target, brings it into focus, and reads the distance mark on the control. Newer laser rangefinders operate by simply sighting any target and pressing a switch to take a very precise distance reading using an invisible laser. Newer golf carts often include GPS tracking which, combined with an electronic map of the course, can serve a similar function.
