Gapping Your Bag on a Launch Monitor

Here's a bet you'll almost certainly lose: write down, right now, your carry distance for every club in your bag. Not "about 150" — the actual number, in the air, before the bounce. Most golfers can't do it, and the ones who try are usually working off one flushed 7-iron from 2019. Then they wonder why they're long over one green and three clubs short of the next par 3.

Gapping is the fix, and it's the single most useful hour you can spend on a launch monitor without changing a thing about your swing. You hit every club, you learn what each one actually carries, and you find out where your set has overlaps and holes. No lessons, no new move, no swing thoughts. Just data — and then a couple of cheap, boring adjustments that quietly save you strokes for years.

Carry is the number that matters

First, get one distinction straight: carry versus total. Carry is how far the ball flies before it lands. Total is carry plus rollout. Your buddy who "hits his 8-iron 165" is usually quoting total, downwind, off a firm fairway, on his best strike of the month.

On approach shots — the shots where distance control actually earns you money — carry is the only number that counts. The bunker doesn't care about your rollout; you either flew it or you didn't. Water, false fronts, tucked pins: all carry problems. Total distance matters off the tee, where rollout is your friend, and almost nowhere else.

This is exactly why a launch monitor is the right tool for the job. The sim gives you carry directly, on every single shot, measured instead of guessed. And it removes the range's two great liars: mystery wind and range balls. (Limited-flight range balls can knock real yardage off your longer clubs, which is one reason so many golfers "gain distance" the moment someone measures them properly.)

How to run the session

Here's the whole protocol. Book an hour in a bay, bring your full set, and work through it like this:

1. Warm up first. Ten minutes of easy wedges. Cold-swing data is garbage data.
2. Start at one end and go club by club. Lob wedge up through driver, or driver down — doesn't matter. Just be systematic.
3. Hit 5–10 shots per club with your normal, on-course swing. Not your "launch monitor swing." You're measuring the golfer who shows up on Saturday, not the one showing off.
4. Throw out the junk. Delete the tops, the shanks, the one you stepped on. But keep your ordinary mishits — the slightly thin one, the toe strike. Those are part of your real game, and your real carry number should include them. Discarding everything but your three purest strikes is how you end up with fantasy yardages and wet golf balls.
5. Record the average carry for each club. Most launch monitor software will average this for you; if not, a notes app works fine.

FlightScope's own guidance is to hit around 10 shots per club and cut the outliers before averaging, and coach Will Shaw at Golf Insider runs the same drill with five shots per club, tossing only the truly dreadful ones. Either way, one hour and one bay gets you through the whole bag.

One warning: this session is boring in the best way. It is not a practice session (see practice with intent for that). You're not fixing anything, you're taking inventory. Resist the urge to start tinkering mid-session.

Reading the chart: overlaps and holes

Now line your averages up from lob wedge to driver and look at the steps between clubs. Healthy gapping is roughly even steps — for most golfers that's somewhere between 8 and 15 yards per club, scaled to your speed. Golf Insider's guideline: shorter hitters should expect 5–8 yards between irons, longer hitters 9–16. The exact number matters less than the consistency.

Two problems show up constantly.

The pileup at the top. This is the classic: 3-wood, 5-wood, hybrid, and 4-iron all carrying within about 15 yards of each other. Four clubs, one job. It happens because long clubs are hard to hit, so most amateurs don't compress any of them well — the 4-iron flies like a 5-iron, the 3-wood flies like a 5-wood, and everything bunches around the same anticlimactic number. If four of your fourteen clubs cover 15 yards of golf course, you're paying a fortune in bag space for redundancy.

The hole at the bottom. Meanwhile, look at your wedges. A stock setup of pitching wedge plus one sand wedge often leaves a 25–30 yard crater between them — and that crater sits exactly in prime scoring range, where you face more shots than anywhere else. Modern pitching wedges have gotten stronger-lofted over the years (plenty are now 43–44 degrees), which quietly widens this hole unless you do something about it.

You may also find small overlaps in the middle — a hybrid and an iron carrying the same number, or a pitching wedge only 5 yards behind your 9-iron. All of it is invisible until you measure it, and all of it is fixable.

Fixing the gaps

The good news: fixing gapping is club adjustment, not swing rebuilding.

Loft tweaks. Most modern irons and adjustable woods can be bent or set a degree or two either way, and a useful rule of thumb is that one degree of loft is worth roughly three yards of carry. A fitter can turn two clubs that carry 148 and 152 into clubs that carry 145 and 155 in about ten minutes. This is the cheapest distance-control upgrade in golf.

Wedge spacing. Build your wedges down from your pitching wedge in 4–6 degree steps — that spacing is what produces natural 10–15 yard gaps at the bottom of the bag. If your PW is 44 degrees, something like 48–52–56 (or 50–56) covers the scoring zone without craters. More on grinds and bounce in wedges, bounce, and grind — but get the lofts right first.

Subtract and add. You get fourteen clubs (here's how that budget works), and every slot in a pileup is a slot you could spend where you actually have a hole. If the 4-iron and hybrid carry the same number, one of them goes — keep whichever you hit more solidly, which your session data will tell you plainly. Spend the freed-up slot on the extra wedge that fills your bottom-end crater. That trade alone is worth more than most driver upgrades.

Then re-check. Gapping isn't permanent — new clubs, a speed gain from lessons, even seasonal changes shift your numbers. FlightScope suggests re-gapping about twice a year, and any time new clubs come in.

Run it at Clubhouse

This is genuinely the perfect bay session, and it needs nothing but you and your clubs. Book an hour, pull up the range in GSPro, and work the protocol above — the launch monitor hands you carry, ball speed, and spin on every shot, and you'll walk out with a card that tells you your real number for all fourteen clubs. Snap a photo of it and put it in your yardage book or phone.

If your chart comes back ugly — a four-club pileup, a wedge crater, gaps that lurch from 6 yards to 22 — that's not a failure, that's the entire point. Bring it to a fitting session and the fix is usually a loft tweak and a swap, not a new set. And if the gaps are inconsistent because the strikes are inconsistent, that's a conversation for Pat, because no amount of loft bending fixes contact.

Either way, you'll never stand over a 160-yard shot guessing again. You'll know. That's the whole game.
