USGA / R&A ruling on Rangefinders

As the governing authorities for the Rules of Golf, R&A Rules Limited (“The R&A” or Royal and Ancient Golf Club i.e. St. Andrews) and the United States Golf Association (“USGA”) issued a ‘Joint Statement of Principles’ on the Rules with regard to golf equipment in May 2002. The principles that they outlined continue to be relevant to the game and have proved to be invaluable in guiding the governing authorities’ actions since their publication eight years ago.

Since then, the effects of advancing equipment technology on the playing of the game have spread way beyond golf clubs and golf balls to electronic devices, especially devices that measure distance. The R&A and USGA are aware that the subject of distance measurement has attracted wide ranging comment and quite a number of conflicting views. It is of the greatest importance to golf’s continuing appeal that such advances are judged against clearly articulated principles that are designed to preserve the integrity of the sport.

Distance Information

In an historical context, the game of golf has seen progressive developments in the means by which distance information is available to golfers. From the early days when selecting a club was a matter of human judgment, the use of yardage books and hole location sheets and reference to on course markings has increased significantly. I remember when you were lucky to have a 150 yardage marker on the hole. Now, many course mark every sprinkler head. Most recently, the use of distance-measuring devices has become more widespread.
The R&A and USGA first allowed the use of distance-measuring devices in January 2006. Prior to this, while the use of yardage books was permitted, the use of distance-measuring devices was prohibited by Rule 14-3. The change introduced in 2006 permitted the committee in charge of a competition or course to introduce a Local Rule allowing distance measuring devices. A very important proviso of this permission is that the device must measure distance only; it must not also measure other conditions such as wind speed or direction, the slope of the ground or the temperature.

The Rules and their Purpose
While now accepting this development in the provision of distance information, The R&A and USGA will remain vigilant when considering the Rules on distance-measuring devices. As with the equipment Rules, the purpose of these Rules is to protect golf’s best traditions, to
prevent an over-reliance on technological advances rather than skill, and to ensure that skill is the dominant element of success throughout the game.  Allowing the use of a measuring device to provide the same information that can be obtained through use of a yardage book or on-course markings is not considered to diminish the skill level required to play the game.  (Imagine that)  The R&A and USGA feel that the current practice of permitting distance measuring devices by Local Rule remains appropriate.   Under the present circumstances, The R&A and USGA are not advocating that this common practice should be changed and neither The R&A nor USGA plan to introduce the Local Rule at any of their championships.

A Clarification of the Rules
The emergence of multi-functional devices that can provide additional information to golfers (that could, for example, further help the golfer to determine how to make his next stroke or that could otherwise affect his playing of the game) is a relatively new development.  For
the avoidance of doubt, the governing bodies do not believe that it is necessary or appropriate for the Rules of Golf to allow all such devices.  The following points clarify how the Rules will be applied:
1. Distance measuring devices (i.e. devices whose primary function is to measure distance) may continue to be used only if the Local Rule is in effect.
2. When the Local Rule is in effect, distance measuring devices must be limited to measuring distance only. The use of a distance measuring device would constitute a breach of the Rules if:
· The device has the capability of gauging or measuring other conditions that might affect play (e.g. wind speed, gradient, temperature, etc), or;
· The device has some other non-conforming feature, including, but not limited to, recommendations that might assist the player in making a stroke or in his play, such as club selection, type of shot to be played (e.g. punch shot, pitch and run, etc.), or green reading (i.e. a recommended line of putt), or other advice-related matters. However, it is permissible to use such a device, during a stipulated round, to access distance information from previous rounds that has been processed prior to the commencement of the current round (e.g. a chart of all club yardages), or;
· The device has the capability to assist in calculating the effective distance between two points (i.e. distance after considering gradient, wind speed and/or direction, temperature or other environmental factors). There would be a breach of the Rules even if all of the above features can be switched off or disengaged, and in fact are switched off or disengaged.
3. Multi-functional devices such as mobile phones, PDAs, etc (i.e. devices that are primarily communication devices, but which may have other potential uses) may be used as follows:
· The device may be used for any non-golfing purpose (e.g. as a communication tool to phone, text or email), subject to any club / course
regulations and the Rules on accessing advice-related matters – see Decision 14-3/16.
· When the Local Rule is in effect, a distance measuring application may be used, provided the specific application is restricted to “distance only” and the device does not have any other “non-conforming” features. This is the case even if these other features are not being used. As above, the Rules on advice-related communications (including the use of the internet) still apply.

The R&A and USGA have no intention to permit the use of electronic devices to go beyond the current Rules and interpretations. This means that distance-measuring devices and applications will be limited to distance information only.  If a device that is being used for distance-measuring purposes has any additional features, all such features must conform to the Rules of Golf.
All manufacturers of distance-measuring products are encouraged to submit their devices or applications to the appropriate governing body for a ruling

Opti-Logic GL Rangefinder for Golf

Opti-logic Insight GL
Opti-Logic has come out with a new series of golf laser rangefinders which, similar to Bushnell, offers an internal pin sensoring technology which locks onto the flag stick to permit easy for all. According to Opti-logic and others around the web, Point and shoot can’t be any simpler. The manufacturer believe they’ve mastered the KIS concept (Keep It Simple). Just press a button, point at the flag and release. That’s it. nothing could be simpler or easier. Pinpointing a flag, bunker, hazard, tree line and a lot more, is as easy as point and shoot. No reflectors. No hesitation.


Min Range: 4 yards
Max Range: 1200 Yards yards (to a reflector)
800 yards (reflector-less) (mode 1)
exceeds 250 yards to a flag
Repeatability & Resolution:+/- 1 yard/meter
Precision: +/- 1 yard/meter
Size: 1.5″x4″x5″
Weight: Less than 11oz.

Nikon 350 Rangefinder

nikon 350, nikon 350g

The Specs:

  • Compact, high-performance laser rangefinder specifically designed for golf
  • First Target Priority Mode enables easy measurement of the distance to your target pin at the golf course
  • Depressing the POWER button provides 8-second continuous measurement, which enables measurement even with slight hand movement.
  • Measurement range: 10-500m (11-550 yd.)
  • Distance measurement display step is 0.5m (shorter than 100m/yd.)
  • High-quality 6x monocular with multilayer coating for bright, clear images
  • Easy one-push measurement after the power is turned on
  • High-eye point design affords eyeglass wearers easy viewing
  • Compact, lightweight design enables easy, single-hand operation
  • Diopter adjustment function
  • Capable of distancing different targets in succession with a single press of the button.
  • Waterproof (up to 1 meter for 10 minutes), but not for underwater usage; the battery chamber is water resistant.
  • Wide temperature tolerance: -10ºC to +50ºC

The Nikon Laser 350G is compact and very easy to use and, of course, has been specifically designed for golf.

First Target Priority mode enables easy measurement of the distance to the target even against a background of trees or buildings. And by ‘target’ it doesn’t have to be the flag. Distances to water/bunker hazards or angles of a dogleg can also be easily measured.

It’s also waterproof, measures from 11 to 550 yards and thanks to the R&A’s recently amended ruling on range finders (Rule 14-3B)* it’s now a legal addition to your golf bag.

One other consideration is that it can also be utilised at the practice ground. Hit each club 10 times, discount your bad shots and record the distance to the good shots, then simply take the average.

In summary, if your preference is for a laser rangefinder, the Nikon Laser 350G is an excellent, and very affordable, option.

If, however, you’re prepared to pay a little more, the Nikon Laser 350G also has a more advanced brother – the 550A S – more suited to the serious amateur and professional.

It takes distance measurement one-step further by allowing for the slope of the golf course terrain. That means that if you have an uphill or downhill shot to play, the Nikon Laser 550A S will take into account both height distances and slope angles and adjust your yardage to the pin accordingly.

Note that, at present, it is only legal for use in practice, not in competition play.
