Best Sim Golf Balls: Kirkland, Pro V1, RCT?
What to Hit and What to Avoid
Kirkland ($15/30) for most sims. Pro V1s for premium. RCT for radar indoors. Range balls wreck screens. Here's what to hit.
The Short Answer
Kirkland ($15/30) for most sims. Pro V1s for premium. RCT for radar indoors. Range balls wreck screens. Here's what to hit.
You spent $2,000 on a launch monitor that measures spin to the nearest 100 RPM. You’re hitting range balls you found in a bucket at the municipal course.
Stop. You’re feeding a precision instrument garbage inputs and wondering why the numbers look wrong.
The ball matters. Not for feel (though that matters too) — for data. Camera-based launch monitors read spin by watching the ball’s surface. Radar units estimate spin from ball flight. Either way, the physical ball you put on the mat affects whether your data is trustworthy.
The One Rule
Radar-based launch monitors measure the ball in flight. They don’t care about markings. They don’t care about color. They read the ball’s spin and speed from the dimples as it flies through the air. Any regulation golf ball works.
Camera-based launch monitors take photos of the ball at impact. They need to see markings on the ball to calculate spin. If you feed them a blank white ball, they shrug and guess.
That’s it. That’s the whole rule. Radar: any ball. Camera: marked ball. The rest is details.
(If you have a Mevo+, it’s a hybrid — radar for speed and launch angle, camera for spin at close range. So Mevo+ needs marked balls too.)
Why the Ball Affects Your Data
Camera-Based Launch Monitors (SkyTrak+, GC3, EYE XO, Square Golf, R50)
These units read spin by photographing the ball at impact. They track the rotation of dimples, markings, or logos between high-speed frames. The clearer the ball’s surface features, the more accurate the spin reading.
What this means: White balls with clear, consistent dimple patterns read best. Balls with markings (a logo, an alignment line) give the camera more reference points. Dirty, scuffed, or colored balls read worse.
Radar-Based Launch Monitors (Mevo+, Garmin R10, Full Swing KIT)
Radar tracks the ball in flight and estimates spin from the trajectory. The ball’s surface matters less — but the ball’s physical properties (weight, compression, dimple pattern) affect how it flies, which affects the radar’s calculations.
What this means: Radar units are less picky about ball surface, but they still need consistent balls. A mixed bucket of range balls gives inconsistent data because each ball flies differently.
Special Balls (RCT, RPT)
Some launch monitors require or work best with special balls:
- Titleist RCT balls have a metal dot inside that helps radar units (Mevo+) read spin indoors. Required for accurate indoor spin on some radar units.
- Callaway RPT balls (used by Rapsodo MLM2PRO) have a specific pattern that the Rapsodo cameras read for measured spin. Required for MLM2PRO’s measured spin feature.
If your launch monitor needs special balls, use them. Don’t try to save $20 by hitting regular balls and getting wrong spin data.
The Best Balls for Simulator Use
1. Kirkland Practice Golf Balls — The Pick ($15 for 30)
This is the answer for most people. Costco’s Kirkland practice balls are 30 balls for $15. Fifty cents each. They perform identically to a standard urethane-covered tour ball for launch monitor purposes.
The secret: they’re not “practice balls” in the way range balls are practice balls. They’re just Kirkland Signature golf balls (the same three-piece urethane ball that gets compared to Pro V1s in every budget ball article) sold in a 30-pack without the retail packaging. They spin, they launch, they feel like a real ball. The launch monitor can’t tell the difference between this and a $5 Pro V1, because there basically isn’t one.
Downside: You get 30 of them and they all look the same. Also, no markings — so camera-based LM owners need to draw a line on them with a Sharpie. Takes 10 seconds per ball.
Best for: Most people. Sim-only use. Budget-conscious setups.
Cost: $15 for 30 at Costco ($0.50/ball).
2. Titleist Pro V1 / Pro V1x (Best Premium)
The gold standard. Consistent dimple pattern, clear white surface, durable. Camera launch monitors read the Pro V1’s dimples cleanly. The alignment stamp gives the camera an extra reference point.
Cost: $55/dozen. Yes, that’s expensive for practice balls. But you’re hitting into a net or screen — they don’t get lost. A dozen Pro V1s lasts months in a simulator.
Better option: Titleist Pro V1 Practice (24-pack for $45). These are Pro V1s that failed aesthetic QC — they play identically but cost half as much. Functionally perfect, cosmetically flawed.
Best for: All camera-based launch monitors. The default recommendation if you want premium feel.
3. Callaway Chrome Soft (Best Value)
Same quality tier as the Pro V1 at a slightly lower price. Clear white surface, consistent dimples, camera-friendly. The Chrome Soft’s alignment line is longer than the Pro V1’s, giving camera units more surface reference.
Cost: $48/dozen.
Better option: Callaway Chrome Soft Practice (24-pack for $30). Same deal as Titleist — cosmetic rejects that play exactly like retail Chrome Softs. Sometimes include mixed colors (yellow, orange) which makes them easy to distinguish from your regular balls.
Best for: Camera-based launch monitors. Great all-around practice ball.
4. Titleist RCT (Best for Radar Units Indoors)
The RCT (Radar Capture Technology) ball has a metal dot inside that helps radar units read spin in short indoor spaces. If you have a Mevo+ or FlightScope unit, RCT balls significantly improve indoor spin accuracy.
Cost: $55/dozen (same as Pro V1).
Best for: FlightScope Mevo+, Mevo Gen 2 (indoor mode). Required for accurate indoor measured spin on radar units.
5. Callaway RPT (Required for Rapsodo MLM2PRO)
If you have a Rapsodo MLM2PRO, you need RPT (Rapsodo Precision Technology) balls for the measured spin feature. These are Chrome Soft or Supersoft balls with a specific pattern that the MLM2PRO’s cameras read. Without them, you get estimated spin, not measured.
Cost: $50-60/dozen.
Best for: Rapsodo MLM2PRO only.
6. Wilson Duo Optix (Best for Camera LMs With Markings)
The Wilson Duo Optix comes with a visible seam that acts as a natural marking for camera-based LMs. No Sharpie needed. Soft feel, low compression, easy on impact screens.
Cost: $30/dozen.
Best for: Anyone with a camera-based LM who doesn’t want to draw lines on balls.
Balls to Avoid
Range Balls
Range balls are inconsistent. Different compression, different dimple patterns, different weights. A bucket of range balls gives you a different ball on every shot. Your data will be all over the place because the balls are all over the place.
Also, range balls have hard, slick covers that damage impact screens faster than regular balls. The cover material is designed for durability at a driving range, not for a soft landing on your $300 screen.
If you’re just swinging to feel your motion, range balls are fine. If you’re reading data, they’re not.
Worn or Scuffed Balls
A ball with a scuff or cut has an inconsistent surface. The camera may read the scuff as a marking, throwing off spin calculations. And on radar units, a damaged cover changes the ball’s aerodynamics enough to affect flight data — even at indoor distances.
Toss scuffed balls. In a simulator, you’re not losing balls to water hazards. There’s no reason to hit a damaged ball.
Brand-New Premium Balls (Screen Scuff Risk)
This sounds counterintuitive — aren’t premium balls the best? Yes, for real golf. But at 190 mph ball speed into an impact screen from 8 feet, a fresh Pro V1 leaves a scuff mark on your screen. Not always, not every time. But often enough that you’ll notice. The screen costs $300+. The ball costs $5. Use the ball you don’t care about.
Colored Balls (Yellow, Orange, Red)
Some camera launch monitors struggle with colored balls. The camera’s image processing is tuned for white balls with dimple contrast. Yellow and orange balls can reduce contrast and cause spin misreads.
Test your specific launch monitor with a colored ball before committing. Some handle it fine (the R50 and GC3 are robust). Others (older SkyTrak units, budget cameras) misread. Bright colors are actually better for finding balls in your net — just test first.
Foam Practice Balls
Foam balls don’t spin like real balls. Camera units can’t read foam spin reliably. Radar units can’t track foam ball flight accurately. See our foam balls guide for the full breakdown — but the short version is: don’t use foam if you care about data.

What About Marked Balls?
If you have a camera-based launch monitor (SkyTrak+, Mevo+, MLM2Pro, SC4 Pro, Eye Mini, or any Golfjoy unit), you need markings. Here are your options:
Draw a line. A Sharpie and a stencil. This takes 10 seconds per ball. Do it while you’re watching TV. Mark 20 balls in one sitting and you’re set for weeks. Use a Callaway Golf Ball Marking Stencil ($12 on Amazon) or just freehand it. The LM doesn’t care about precision — it just needs something contrast-y on the ball to track rotation.
Buy pre-marked. Callaway and Titleist both sell practice balls with alignment lines or dots. Callaway’s practice balls often come with a line. Wilson’s Duo Optix come with a visible seam. Any ball that has a line or a pattern works.
Reflective dots. The Garmin R10 needs three reflective dots applied to the ball for spin measurement. You can buy R10 reflective dot stickers on Amazon for $8 (800 dots). They stick to any ball. Apply three dots in a triangle pattern. Works fine. Takes 30 seconds per ball.
The re-mark trick. When your dots wear off, clean the ball with rubbing alcohol and reapply. The same ball lasts indefinitely. Across forum threads, MLM2Pro owners report using the same 12 balls for six months with fresh dots every few weeks.
How Many Balls Do You Need?
For simulator use, 6-12 balls is plenty. You’re hitting into a net or screen. The balls come back to you (or you pick them up). You don’t need a bucket.
A dozen quality balls lasts 3-6 months in a simulator before they get too scuffed for reliable data. Rotate them — don’t hit the same ball 500 times. Spread the wear across all 12.
Budget: $15 (Kirkland practice) to $55 (premium). That’s your ball cost for 3-6 months of simulator use. Not bad.
Screen Durability: Does the Ball Matter?
Yes. A harder ball (Pro V1) hits your impact screen harder than a softer ball (Duo Optix). Over thousands of shots, harder balls wear the screen faster.
If screen longevity is a concern, consider a slightly softer ball for high-volume practice. But don’t sacrifice data accuracy for screen life — screens are replaceable ($150-300), and the whole point of a simulator is accurate data.
FAQ
Can I use real golf balls indoors?
Yes. Any regulation golf ball is safe for impact screens at normal swing speeds. The screen is designed to stop a ball at 190 mph. A standard ball won’t damage it. The only exception is brand-new premium balls (Pro V1, TP5, Chrome Soft) which can leave scuff marks on the screen fabric — not damage, just discoloration. Use practice balls or slightly used premium balls instead.
Do I need special balls for a golf simulator?
No. Any standard golf ball works with radar-based launch monitors. Camera-based LMs need balls with visible markings (dots, lines, or patterns). The $40 “simulator balls” sold on Amazon are a waste of money — a $0.50 Kirkland ball with a Sharpie line does the same thing.
Why does my launch monitor show the wrong spin?
If you have a camera-based LM and you’re using blank white balls, that’s why. The camera can’t see rotation on a blank surface. Draw lines on the ball or buy pre-marked balls. If you have a radar LM and the data looks wrong, try a different ball — some worn balls have damaged covers that cause inconsistent aerodynamics even at 8 feet.
What about colored golf balls?
Most launch monitors don’t care about ball color. Red, yellow, orange, pink — they all read fine. Matte finishes can be slightly less reflective for camera LMs (the ball appears dimmer in the impact photo), but in practice it rarely matters. Bright colors are actually better because you can find them in your net faster.
What about foam or plastic practice balls?
You can use them, but the data will be useless. Foam balls don’t compress like real golf balls. They spin differently, launch differently, and feel nothing like hitting a real shot. Your launch monitor will show numbers, but those numbers have no relation to what happens when you hit a real ball. Just use real balls.
Do I need Titleist RCT balls?
Only if you have a radar-based launch monitor and you’re using it indoors. The RCT ball’s metal layer helps radar units (Mevo+, FlightScope) measure spin accurately at short indoor distances. If you have a camera-based LM, regular balls work fine. If you have a radar LM outdoors, the RCT isn’t needed either — the radar has enough flight path to calculate spin naturally.
Can I use Kirkland practice balls with a camera-based LM?
Yes, but you need to draw markings on them. They’re blank white balls with no markings. Grab a Sharpie, draw a line from pole to pole, and you’re set. The camera needs that contrast to track rotation. Takes 10 seconds.
The Verdict
Buy the Kirkland practice 30-pack for $15. If you have a camera-based LM, spend 10 minutes drawing lines on them with a Sharpie. If you have a Garmin R10 or R50, stick three reflective dots on each one. If you have a Mevo+ indoors, buy the Titleist RCT balls for accurate spin data.
The whole setup costs $15-20 and lasts six months. When you run out, buy another pack.
You don’t need $55 Pro V1s (unless you want the best feel). You don’t need special simulator balls (those exist at $40/dozen and they’re a scam). You don’t need range balls (they’ll trash your screen and give you garbage data). You need Kirklands with a Sharpie line.
That’s it. That’s the whole guide. Buy the balls, draw the line, hit the shots.
