Adding measurements from laser to yardage book for tournaments

[flopster]

What the real question here is can a player make additional measurements using the slope feature during practice rounds and use those measurements for a tournament afterwards? I did see numerous professionals using Bushnells just like mine at Olympic and was curious if they were also getting elevation distances as well.

No problem. Information collected before a round may be recorded for use during the round. You may not actually measure gradient during a round.

The lasers that the pros used will not have a gradient feature.

Why would they not have the slope feature if it's allowed to retrieve important measurements? IMO this is imperative to playing from elevations on a course you would be unfamiliar with. Still a little confused but I do believe in a practice round it will be okay to obtain gradient measurements during a practice round and record on a yardage book for use during competition. I'm sorry if I misunderstood.

Perhaps I misunderstood. I assumed you meant they were using bushnells during the round.

They probably were using elevation. But their yardage books will often have those pre-marked, too, and often they're just confirming things in practice rounds.

Note that elevation can play differently if you hit the ball higher or lower than average.

Do you mean during the round?

If their bushnells have an elevation feature they cannot be used during a round (even if the feature is not used or even switched off).

Yeah, we're talking about pros using range finders WITH elevation enabled DURING SCORING ROUNDS AT THE U.S. OPEN!

He's clearly talking about practice rounds. Both the OP and I have said "practice rounds."

[Rulesman]

The construction of the sentences misled me into thinking that the posts were suggesting that the pros may be using (the same) DMDs in scoring rounds that they had previously used in practice rounds to measure gradient.

If that was so, then they were in breach of the rule whether or not the feature was used or enabled.

But the pros don't allow dmd's of any kind during competition anyway, do they? I've never seen a caddy pull out a laser during a round.

No they don't.  The caddie and the player add to the preprinted yardage books with information obtained in many ways - with lasers, by pacing, by playing those shots in practice rounds.  On the greens, they also roll balls and putt from every possible angle to each of the anticipated hole positions.  That information is also added to the yardage books that both of them carry during tournament play.

Despite all of that planning and preparation, they still misclub, they still misread putts.  It all goes to show just how tough a game this really is.

Correct: the PGA Tour (and the USGA, and the R&A;, in events they control) does not allow DMDs at all.

That's precisely why assuming that's what's being asked about players at the U.S. Open is ridiculous.

Using any information gathered and written down in a yardage book from an electronic device during practice is OK...since the yardage book isn't an electronic device...

[flopster]

The lasers that the pros used will not have a gradient feature.

Why??? I understand what Erik said about players hitting shots at different elevations but I'm also aware you do get the degrees the elevation is as well and that may be prudent info for a player at that level. I think the real question just never got through well enough but it eventually got answered.

It's OK because the information has been gathered before the round rather than because the yardage book isn't electronic.  There is nothing to stop a player using an electronic device during a round to look up information previously entered into it. What he cannot of course do, is to use it to calculate, measure or gauge anything during his round that might assist his play.

Unless there is a Local Rule permitting the measuring of distance and the device has no non-conforming functions.

Indeed, but then only distance.  Your and raise you .

so your're saying the one that measures gravitational pull on the ball can't be used unless otherwise stated in a local rule? ;-)

the answer to your first question is yes ;-) simple right lol
