What does 1 degree equal in distance

[Lagerlover]

A bit of a how long is a piece of string type question, but with optimum swing speed, launch angle, and any other factor/s being at their most ideal to maximise distance, what would the difference between 8.5 and 9.5 degrees represent in meters??

[markTHEblake]

I will take a stab in the dark. the 9.5 will have slightly longer carry.

[mike]

12 metres. Exactly.

[Lagerlover]

12 metres. Exactly.

Sorry Mike, which way, 9.5 plus 12 more than 8.5??

[Outcast]

:roll:
12 metres. Exactly.

I'm sorry Mike but, on this you are wrong! It's 12.32 metres Exactly:roll:

Unless u can put an identical swing on the club every single time, not enough to worry about I would say.

[razaar]

Probably nothing. The ball will take off apprx 2* less with both clubs. 7.5* with the 9.5 driver and 6.5* with the 8.5 driver. Much depends on the angle of attack, whether it is a decending, accending or level blow. lOne degree won't make any difference to ball speed, so it is possible that there may even be a slight loss of distance on a solf fairway and a slight increase on a hard fairway.

Are we talking left side or right side of the fairway?
:lol:

[matty]

Probably whatever you want it to represent.

[Dotty]

African or European metre ?

[mike]

Take your pick.

You were never going to get a serious answer, especially not from me. :D

Too many variables.

[mike]

African or European metre ?You wouldn't believe how many times I've watched that movie.

[Yossarian]

African or European metre ?

Damn it! Great call.

[SeptemberSquall]

Damn it! Great call.

boom boom, tish...

What is the ball speed??? - my software can tell you exactly.

Can also do it into the wind - with the wind, on a hot day or a cold day . . .

Help me out and i will plug it in.

[mike]

Well there you go.

[yannana]

The 9.5 will have slightly longer carry. About 12 metres.

[TourFit]

Not for a 70 yr old with a 72mph driver swing speed it won't...

The point is, there are far too many variables to answer the question accurately. That's why Virge asked about swing speed, he should also have asked about angle of attack because that will affect the ACTUAL loft of the club at impact and then have a knock-on effect to launch angle, which then makes the difference to carry distance and roll after impact (due to descent angle).

Exactly . . . so, if you want an answer - give me a question.

[mike]

Altitude too.

Apologies guys, I thought there may have been one answer to this question if everything was at it's optimum condition.

So can I word this better and ask, in the majority of situations would you get more distance out of an 8.5 degree driver compared to a 9.5 degree driver, or is that still too mirky?

I am actually happy with how my current driver behaves, it's only because I found a cheap 9.5 to have a go at, that I'm giving a swap some thought.

Thanks to all those who offered thoughts.

I can answer that - if you give me your ball speed . . .

Cant do it with out ball speed...

[Lagerlover]

Thanks virge, I will jump on a monitor sometime next week

[rubin]

out of curiosity Virge - lets say at 185 - 190mph.

[virge666]

You know that is long driving speed . . .

[rubin]

You know that is long driving speed . . .

I do. LL did mention for maximum distance.

i have seen a few get up to the 185 188 mark.

think Bubba is about 188-194ish.

At that speed the difference in carry is 3 yards.

i would assume that the level of carry would increase slightly at a slightly slower swing speed? in comparison to an 8.5

[virge666]

It is more about controlling spin rates with that kind of swing speed.

[Veefore]

What about at say 140-145mph. Comparing a 10.5° to a 9.5° and 8.5° with either a level or slightly rising club at impact?

[razaar]

The scientific publication "Search for the Perfect Swing" Chapter23 Ballistics of Golf provides a chart with some details which may help with this. A driver with zero loft (which will be a direct hit) with a swing speed of 100mph achieves 135mph ball speed with zero spin and flat trajectory (0*). A driver with 10* loft (less direct hit because of the loft) with 100mph swing speed achieves a ball speed of 134mph with a spin rate of 60revs per sec and a trajectory of 8*.

And that would be with 1970's technology...

Meanwhile with a current golf ball and club - the numbers are substantially higher.

Ray, please find a newer book when talking about equipment . . . this one just does not cut it anymore.

[razaar]

Actually it is 1960's technology. The ball speeds will be different but the science is still the same. Wishon gives a maximum smash factor of 1.5 ball speed to clubhead speed but it has to be struck right on the sweet spot (about the size of this .) to get those numbers.
