Golf Simulator Club Fitting at Home: DIY Distance Gapping (2026)

The first thing to do with a new launch monitor in a garage or garden is hit your 7-iron and 6-iron back to back. Often the two carry numbers land within a couple of yards of each other. That's a wasted club, and the golfer had no idea until the screen said so. You don't need a fitting studio to catch that any more — if you've got a simulator or launch monitor at home, you already own the tool the fitters charge you to use. Here's how I'd actually use it to gap your bag, without pretending it replaces everything a proper fitter does.

Distance gapping is not the same as a full fitting

Let's be straight about the line I won't let people cross. Distance gapping means checking the carry gaps between your clubs and closing the ones that are too tight or too wide. That's a job your home launch monitor does brilliantly, because it comes down to one number you can trust: carry distance. Full club fitting — shaft profile, lie angle, grip size, building a set from scratch — is a different animal that leans on club-delivery data and a fitter's eye. Your simulator can inform those decisions and stop you buying the wrong thing, but it doesn't finish the job on its own.

So treat this as the DIY half: get your carry gaps clean, spot the clubs doing nothing, and walk into any paid fitting already knowing what your bag actually does.

The only number that matters for gapping: carry

Total distance is the number every golfer quotes down the pub, and it's the number I ignore for gapping. Total is carry plus roll, and roll depends on the ground — firm links in July versus a soggy fairway in February. Carry is the club's honest signature, and it's the same indoors as it is on the course — which is the whole reason a home launch monitor is legitimate for this. Through the irons I look for roughly 10–15 yards a club: any tighter and two clubs are doing one job; any wider and there's a shot you simply can't hit.

One more split worth knowing: every unit here measures ball flight and turns it into carry, which is all gapping needs. Only the premium units also read the club — path, face, dynamic loft, lie — and that's what edges a session toward a real fitting. For most people at home, ball data is plenty.

Radar or camera — and where it sits in the room

This decides your room layout more than the price does, and it's the thing people forget until the box arrives. Radar units read the ball flying away from them, so they live behind the ball — you want roughly 2.4m of clear space behind your ball position. In a tight garage that can mean the unit ends up near the back wall, and you have to make sure it can see enough flight before the ball hits the screen.

Camera-based units are the opposite. They sit in front of or beside the ball and only need around 0.6m of clearance, which is why they thrive in short rooms and small enclosures. If your space is tight front-to-back, a camera unit almost always wins on fit alone — before you've even looked at the data quality.

How I run a home gapping session

The data is only as good as the way you collect it. Here's the routine I recommend:

• Warm up properly. Cold-muscle numbers are junk. Hit a dozen easy shots before anything counts.
• Use one ball model throughout. Mixing a premium ball with range rocks skews spin and carry. Pick one and stick with it.
• Hit about ten shots per club. Bin the best and worst, average the rest. That average carry is what you play with, not your one flushed career shot.
• Work top-down and log it. Wedges up through irons, then hybrids, fairways and driver, mat and ball position consistent. Write the average carry next to each club — the gaps jump off the page in a column.

The single biggest mistake I see is gapping off your best strike. Your longest 7-iron of the day is not your 7-iron — the average is. Gap to the average and your on-course club selection gets a lot more honest.

The units I'd actually use for this

You do not need to spend four grand to gap a bag. Here's the ladder I talk customers through, cheapest first, with what each one gives you for fitting-style work.

Garmin Approach R10 — £421

The most affordable way in that I'll happily recommend. It's radar, so mind that 2.4m behind the ball, but the carry numbers are consistent enough to gap a bag confidently. No real club data to speak of, and you're leaning on ballistic modelling rather than measured spin, but for a first launch monitor doing gapping duty it punches miles above £421.

FlightScope Mevo Gen2 — £1,199

This is the one I point most home golfers at for gapping, and it's the budget comparator worth understanding properly — the Mevo Gen2 is a radar unit that measures spin rather than estimating it, which sharpens the carry data noticeably. It reads club head speed too, so you get a genuine feel for whether a swing change is doing anything. For the money, it's the sweet spot between trustworthy and sane.

Foresight GC3 — £7,500

Camera-based photometric data, and the carry numbers get fitting-bay tight. The GC3 sits beside the ball on about 0.6m of clearance, so it's a dream in short rooms. Ball data first, with club speed, attack angle and path once the reflective marker is on the club, and if you want your gapping repeatable to the yard, this is where it starts.

Uneekor Eye Mini — £2,999

A camera unit that adds club-delivery data, so a home setup genuinely starts to resemble a fitting bay — path, face and impact, the numbers a fitter reads. If your DIY itch has gone past gapping into strike and lie, this is the honest entry point. There's a lighter Eye Mini Lite at £2,806 for camera accuracy without the full data suite.

Garmin Approach R50 — £4,299

The all-in-one. Camera-based, sits in front of or beside the ball, with a built-in touchscreen so the family can use it without a laptop. A brilliant switch-on simulator that also gives solid gapping data — the pick if you want practice, play and gapping in one box.

Foresight GCQuad — £16,788

The one the actual fitters use. Quadrascopic cameras read ball and club — path, face, lie, loft delivery — so it's a true fitting instrument. Overkill for closing a couple of iron gaps, and I'll tell you that to your face, but if you want a fitting studio at home, nothing here touches it.

The fixes you can make from your own data

Once the carry column is in front of you, a few honest tweaks fall out:

• Kill the duplicate. Two clubs carrying the same? One's redundant — a loft tweak re-spaces them, or you drop one and add a club where you've got a hole.
• Fill the wedge gaps. If your gap between pitching wedge and sand wedge is 25 yards, a gap wedge is a genuine scoring upgrade — and the data tells you the exact loft to buy.
• Question the long irons. If your 4-iron carries the same as your 5-iron, or won't launch, a hybrid usually carries further, higher and lands softer.
• Sanity-check the driver. Compare launch and spin at different tee heights to see which gives more carry. Loft and shaft changes still want a fitter, but you'll know what you're chasing.

When you still need a real fitter

I sell these units and I'll still tell you where the human wins. Lie-angle bending, shaft selection under real load, grip sizing, and building a coherent set from scratch — that's fitter territory, and a UK session typically runs £50–£150. The smart play: do your gapping at home first, arrive with your average carries and problem clubs already flagged, and let the fitter spend the paid hour on the things only they can do.

Which one for gapping vs fitting

FAQ

Can I really gap my bag at home without a fitter?

Yes — gapping is the part that transfers cleanly to a home launch monitor, because it hinges on carry distance, which reads the same indoors as out. Hit ten shots a club, bin the outliers, average the rest, and your carry gaps are as good as anything you'd get in a bay. Shaft and lie work is where you still want a fitter.

Do I need club data or is ball data enough?

For distance gapping, ball data is plenty — carry is derived from ball speed, launch and spin, and every unit here measures those. Club data (path, face, lie, dynamic loft) only matters once you're chasing strike patterns or lie angle, which is when a Uneekor Eye Mini or GCQuad earns its keep.

Why should I gap to carry and not total distance?

Total distance includes roll, and roll changes with the ground — firm in summer, soft in winter. Carry is the club's fixed signature and it's identical indoors, so it's the only number that gives you a stable ladder to gap against. Quote total down the pub; gap on carry.

How much clearance does each type of monitor need behind the ball?

Radar units like the R10 and Mevo Gen2 read the ball flying away, so they sit behind your hitting spot and want roughly 2.4m of clearance. Camera units like the GC3, Eye Mini and R50 sit in front of or beside the ball and only need about 0.6m — far friendlier for short garages and small enclosures.

What's the cheapest launch monitor that gaps a bag properly?

The Garmin Approach R10 at £421 is the floor I'll recommend for gapping — consistent carry numbers, just mind the space behind the ball. If you can stretch, the FlightScope Mevo Gen2 at £1,199 measures spin rather than modelling it, and that's the one I steer most home golfers toward.

My honest steer

If you just want to stop carrying two clubs the same distance, buy the R10, run one careful session and fix your bag this weekend. If you want carry numbers you'll trust for years, the Mevo Gen2 is the one most people should own. Go camera — GC3 or Eye Mini — when short-room fit or fitting-grade accuracy matters, and only the GCQuad if you truly want a fitting studio at home. Whatever you land on, do the DIY gapping first: it's the highest-value hour you'll spend on your bag, and it costs nothing but a bucket of the same ball.
