When Two Clubs Report the Same Distance

I do not run fittings. I build clubs and I audit sets, which means the version of this problem I see arrives on a bench rather than in a bay, usually attached to a note from Rosalind or Perpetua saying something like "six and seven are three yards apart, find out why".

It happens constantly. Of the full set audits that come through here, something close to half contain at least one pair of consecutive clubs producing carries within five yards of each other. Almost none of those players knew. You cannot feel a three-yard difference on a golf course, so the set quietly stops being a set and nobody is alerted.

There are four causes. I check them in this order, cheapest first, and the fourth is by some margin the least common despite being the one people assume.

One: The Lofts Are Not What Is Stamped on Them

First thing, always, because it is quick and because it is the answer more often than the other three combined.

Every head goes on the gauge. What I am looking for is the progression: whether the loft steps evenly from club to club, not whether any individual head matches its stamp. Manufacturing tolerance means a stamped thirty-degree head might genuinely measure twenty-nine and a half, and that is fine and normal. What is not fine is when one head in the middle of a set sits a degree and a half out of line with its neighbours.

Two ways that happens. Occasionally it left the factory that way, at the wide end of tolerance, and nobody checked. Far more often somebody has bent it since. A set that has had a lie adjustment at some point in its life has frequently had its lofts disturbed at the same time, because the two are adjusted on the same machine and it is easy to move one while working on the other.

The fix is a bending job. Nine dollars a club, two days, and it resolves a good half of every doubling case that comes through here. This is the least glamorous paragraph on this website and it is the one I would most like people to read.

Two: The Lengths Have Drifted

Second check, also on the bench, also quick.

Clubs in a set should step in length by a consistent increment, generally half an inch between irons. When one does not, the club that is short relative to its neighbour will produce less speed and therefore less carry, closing the gap below it and widening the one above.

The usual causes are a reshaft done without matching the original length, a grip change where somebody trimmed the butt to remove a worn section, or a set that was assembled from two different sources at different times. Mixed sets are increasingly common as people replace broken clubs individually, and the replacement is very rarely built to match what it joined.

I measure from the heel with the club soled properly. It is worth saying that a lot of the length figures people believe about their own clubs come from a manufacturer's chart rather than from a ruler, and charts describe intentions rather than objects.

Three: The Shafts Are Not Progressing

Third check, and the first one that requires anything beyond a gauge.

Across an iron set, the assembled clubs should get progressively stiffer as they get shorter. That progression should be smooth. When one club in the middle is noticeably out of step, because it was reshafted with something different, or because it came from another set, or because it was tip-trimmed differently during assembly, it will behave differently in a way the player experiences as "that one is odd" without being able to say more.

I take a frequency reading on every club in an audit and write the series out. A smooth series looks like a staircase. A disturbed one has a step that is obviously too tall or too short, and it usually sits exactly where the player says the trouble is.

The fix here depends. Sometimes it is a reshaft to match, which is thirty-two dollars plus a shaft. Sometimes, when the odd club out is one the player likes and the rest of the set is what is wrong, the honest answer is more expensive and I say so.

Four: The Player Cannot Separate Them

Last, and the one that cannot be fixed on a bench.

Sometimes every measurement checks out. Lofts step evenly, lengths are correct, the frequency series is smooth, and two clubs still produce the same carry. What is happening is that the player is delivering them almost identically, usually because the loft difference between them is too small relative to how much their own strike varies.

This shows up most often at the top of an iron set. A four iron and a five iron separated by three degrees, in the hands of a player whose spread is twenty-five yards, are effectively the same club. The three degrees are real and the player's variation is swallowing them whole.

There is no bench fix. The answers are either to remove one of the two clubs and replace it with something genuinely different, which is usually where a hybrid conversation starts, or to accept it and use the freed slot elsewhere in the bag.

I mention this last for a reason. It is the diagnosis a lot of shops reach first, because it is the one that leads to a purchase. In my experience it is the correct answer in perhaps one doubling case in six.

What an Audit Costs Against What It Finds

A full set audit here is sixty-five dollars and takes two days. Roughly four sets in ten come back with a finding worth acting on, and the median cost of acting on it is under fifty dollars of additional labour.

I am aware that this is a strange thing for a business to publish, since the alternative diagnosis in every one of these cases is "you need new irons". But the gauge says what the gauge says, and I would rather write it down than pretend the last decade of audits pointed somewhere else.

How to Tell Whether You Have This

You almost certainly cannot tell on a golf course, which is the entire difficulty. Three yards is invisible inside normal variation, and players compensate for a doubled pair without ever consciously noticing they are doing it. The usual symptom is a vague preference: a club you reach for and one you do not, in the same part of the bag, for reasons you could not articulate.

If you have a club like that, it is worth putting the set on a gauge. It costs sixty-five dollars and the odds are close to even that something turns up.
