11 distance-measuring devices that the Rules of Golf will soon allow

A proposed change to the Rules of Golf allows players to use distance-measuring devices. Here's a round-up of the best ones, including GPS units, rangefinders and smart gadgets.

Tech-heads, rejoice! A proposed change to the Rules of Golf—if adopted, the rule will go into effect in 2019—allows players to use distance-measuring devices (DMD) including GPS units, rangefinders, and smartphone or tablet apps during play, unless a Local Rule prohibits it. (Currently, DMDs are permitted under a local rule so, in essence, the rule would be flipped.) When it comes to high-tech DMDs, the future is now. Here’s a roundup of the best stroke-saving models.

SCOREBAND PULSE

Available at amazon.com, $136 

The Pulse features 6x magnification, a range up to 400 yards (250 yards to flags), a user-friendly flag-lock display, is accurate by plus or minus one yard, and can display distances in meters. It also weighs less than five ounces and fits comfortably in your hand with dimensions of 4 x 3 x 1.5. The $136 price tag proves that good things can come in small, not-too pricey packages.

TLINK

Weighing just an ounce, this Bluetooth-enabled device pairs with the TLink app on your smartphone for instant yardages. It's also a pedometer, tracking steps, calories burned, and distance walked on or off the course. Enter scores, putts, and greens and fairways hit for post-round review. (Stat tracking is $1/round, $5/month, or $30/year.) The TLink comes with a white or black wristband and a belt clip. Red, blue, and pink wristbands are sold separately ($15 apiece or $30 for all three).

The device also shows the shape of the green and gives exact yardages from your angle of approach.

Available at amazon.com, from $400 

The company's VR (vibration reduction) system compensates for hand movement, which makes it easier to direct the laser to your target. The powerful units provide distances to the nearest 0.1-yard in less than half a second, with a range up to 1,000 yards, while a scan mode is also available. Locked On Technology helps deliver accurate distances to the flag, even when objects like trees, bushes, or buildings appear in the rangefinder.

LEUPOLD GX–2i2

Available at amazon.com, $230 

A high-definition LCD display and the company's updated pin-finding technology delivers faster, more precise distances by better filtering out background objects. The 6.8-ounce unit can also capture distances through fog, has 6x magnification and seven aiming reticles (crosshair styles), and works with pins outfitted with reflective prisms up to 800 yards away. Plus, the rangefinder has a "True Golf Range" mode that provides measurements that factor in slope, temperature and altitude to within one-half yard, and even recommends what club to hit. (The mode can be turned off for use in tournaments).

GOLFBUDDY VOICE 2

Available at amazon.com, $130 

The water-resistant, second-generation Voice 2 has more battery life (14 hours) than before. Tap the main button to hear the distance to the middle of the green, or hold it down for the yardage to the front and back. The screen displays all three yardages and shows the shape of the green. Clip it to your hat, pocket, belt, or wristband (sold separately, $25). Comes in blue/white or rose/white.

CALLAWAY GPSy

Available at amazon.com, $180 

This sleek, lightweight unit features an odometer, shot distance calculator, and the ability to enter your score, number of greens in regulation and number of putts per round.

Available at amazon.com, from $300 

The ergonomic Tour V4 is twice as fast as the company's Tour V3 and 30% smaller. It weighs 6.6 ounces, has a range from 5 to 1,000 yards (400 yards to flags), and 5x magnification. The Slope Edition has patented technology to compensate for elevation changes, and is legal for tournament play as long as the Slope mode is turned off. But here’s the coolest feature— the unit provides short vibrating pulses when it locks onto flags, so even when your game is off, you can claim a great "feel" for distance.

GARMIN APPROACH X40

Available at amazon.com, $250 

This watch doubles as an activity tracker, recording distance walked, calories burned, and heart rate.
