Launch Monitor Placement: Exact Specs Guide
Exact Distances, Tilt Specs, and Room Depth Requirements for Every Major Unit
Placement is the biggest variable in LM accuracy. Exact distances, tilt angles, and room depth for GC3, R10, Mevo+, EYE MINI, ProTee VX, and more.
The Short Answer
Placement is the biggest variable in LM accuracy. Exact distances, tilt angles, and room depth for GC3, R10, Mevo+, EYE MINI, ProTee VX, and more.
I have a buddy — let’s call him Dave — who spent $2,500 on a Bushnell Launch Pro and spent two months convincing himself his swing was broken. He was slicing everything. Numbers made no sense. Club path showing +6 degrees every time.
His monitor was six inches too far from the ball and tilted three degrees off perpendicular.
That six inches and three degrees turned a perfectly fine swing into what looked like a hosel rocket factory. He almost returned the unit, sold his net, and gave up on the whole idea. All because of placement.
Your launch monitor can be the best in the world. If you put it in the wrong spot, it lies to you. Period. A $14,000 TrackMan iO misaligned by a few degrees will give you worse data than a $500 Garmin R10 set up correctly. I’m not exaggerating.
This guide covers exactly where to put every major launch monitor on the market, what tilt and height they need, and how much room your space actually requires. Not generic advice. Specific numbers you can take to your garage and use.
The Big Three: Where Your Monitor Sits
Every launch monitor fits one of three placement zones. Your room depth determines which zone you’re shopping in, not the other way around.
Radar Units (Behind the Golfer)
Radar monitors sit on the floor behind you and track the ball through flight. They need clear line of sight from the unit to the ball and from the ball to the screen. The radar beam needs room to develop — that’s why they need so much depth.
Which units: Garmin R10, FlightScope Mevo+ and Mevo Gen 2, Rapsodo MLM2PRO, Full Swing KIT, TrackMan 4
Sits: Floor behind the golfer, centered on the target line
Room depth required: 18 to 21 feet minimum
Photometric/Camera Units (Beside the Ball)
Camera monitors sit beside or just ahead of the ball and capture data at impact. They measure the ball in the first few inches after contact. Everything happens in a fraction of a second. No ball flight required.
Which units: SkyTrak+, Foresight GC3, Bushnell Launch Pro, Foresight GCQuad, Square Golf, Garmin R50, Uneekor Eye Mini, GolfJoy Spica 3, Voice Caddie SC4 Pro
Sits: Floor beside the ball, typically 6 to 24 inches to the side
Room depth required: 12 to 17 feet
Overhead Units (Ceiling-Mounted)
Overhead monitors mount to the ceiling above the hitting area. They look down at the hitting zone. No floor unit to trip over, no repositioning for lefties. But they require a permanent mount and sufficient ceiling height.
Which units: Uneekor Eye XO and Eye XO2, TrackMan iO, ProTee VX, GolfIn IDRA II, Foresight GCHawk, Uneekor Eye XR
Sits: Ceiling, 3 to 4 feet in front of the tee, 9 to 10 feet up
Room depth required: 14 to 18 feet. Ceiling height: 9 feet minimum, 10 feet recommended
Here’s the thing that trips most people up: you don’t choose the technology and then check if your room fits. You measure your room first and let it pick your technology. A 14-foot deep garage? You’re buying a camera unit. End of discussion.
The Room Depth Formula
Before we get to specific products, let’s establish how room depth actually works. It’s three zones:
Zone 1: Behind-screen buffer (1 to 1.5 feet) Your impact screen needs space to flex backward when a ball hits it at 150 mph. If the screen is against the wall, the ball punches through. If it’s 12 inches off the wall, the screen absorbs the energy and the ball drops. Don’t skip this.
Zone 2: Ball-to-screen distance (10 feet minimum) Ten feet is the safety minimum. Some manufacturers quote 8 feet as a “tracking minimum” — that’s what the sensor needs to see data, not what’s safe for your face. The ball comes back off the screen. Ten feet gives it room to slow down before it reaches you. Use 10 feet. Not 9. Not 8. The one guy who thought 8 feet was fine caught a Titleist in the teeth. Don’t be that guy.
Zone 3: Behind the ball (varies by technology) For camera units: 2 to 4 feet. Just enough room to swing a club and not hit the wall. For radar units: 7 to 9 feet. The radar beam needs room behind the ball to build its tracking arc. For overhead units: 3 to 5 feet. You need swing clearance. The monitor is on the ceiling.
Total formula: Zone 1 + Zone 2 + Zone 3 = minimum room depth
For a camera setup: 1.5 + 10 + 4 = 15.5 feet minimum. For a radar setup: 1.5 + 10 + 8 = 19.5 feet minimum. For an overhead setup: 1.5 + 10 + 5 = 16.5 feet minimum.
Measure your room. Plug in the numbers. If the total doesn’t fit, you’re buying a different type.
Now let’s get specific.
Radar Placement: Exact Distances Per Unit
Radar is the trickiest placement because the unit sits behind you and you can’t see it while you’re swinging. Get it wrong and every number is off.
Garmin Approach R10
The R10 is the most popular launch monitor on the market, which means it’s also the most commonly mispositioned.
| Parameter | Specification |
|---|---|
| Unit to ball (behind golfer) | 6 to 8 feet; 7 feet recommended |
| Ball to screen (tracking minimum) | 8 feet (safety minimum is 10 feet — use 10) |
| Ball to screen (best accuracy) | 13+ feet |
| Unit height | Bottom edge level with or slightly above hitting mat surface |
| Lateral ball offset | Ball can be up to 1 foot either side of target line |
| Total room depth needed | 18 to 20 feet |
The R10’s dirty secret: Garmin says 8 feet ball-to-screen is enough for tracking. That’s true for getting numbers. It’s NOT true for getting accurate spin data. The R10 estimates spin from ball flight curvature, and it needs at least 13 feet of flight to do that well. If your room is 18 feet deep, you’re getting estimated spin (which means wedge numbers will be unreliable). If your room is 22 feet deep, the R10 performs noticeably better.
Most guys put the R10 too close to the ball (under 6 feet) because their room is tight. If the R10 is closer than 6 feet, it can’t build a proper tracking arc. Ball speed and club speed readings drift. If you’re seeing 95 mph club speed and you’re not a professional athlete, check your R10 distance first.
The R10 also needs to be on the same surface as the ball. Not on a stool. Not on a box. On the floor or hitting mat. The radar beam comes out at a fixed angle and expects the ball to be in a specific vertical window.
FlightScope Mevo+ and Mevo Gen 2
The Mevo+ has a Short Indoor Mode that lets it work in tighter spaces. But “short” is relative.
| Parameter | Short Indoor Mode | Regular Mode |
|---|---|---|
| Unit to ball | 8 feet | 7 to 9 feet |
| Ball to screen (tracking spec) | 8 feet (use 10 for safety) | 13 feet (best accuracy) |
| Required tilt | 18 degrees | 18 degrees |
| Roll angle | 0 degrees (level) | 0 degrees (level) |
| Total room depth needed | 19 feet | 20 to 23 feet |
The Mevo Gen 2 uses the same Fusion Tracking as the Mevo+ and has the same placement requirements. That 18-degree tilt spec is critical — the radar beam points upward at an angle, and if the unit is flat on the ground, the beam misses the ball’s flight path entirely. You need the unit tilted back so the radar sees the ball’s trajectory.
FlightScope sells a tilt stand. Use it. A few degrees off and your launch angle readings will be consistently low or high. The Mevo+ manual specifies 18 degrees, not “roughly 20” or “eyeball it.” Get an angle finder or use the alignment app. I’ve seen guys use folded cardboard under the back edge and wonder why their data was erratic.
Rapsodo MLM2PRO
| Parameter | Specification |
|---|---|
| Unit to ball | 6.5 to 8.5 feet |
| Ball to screen | 8 feet minimum (10 feet safety) |
| Total room depth needed | 17 to 20 feet |
| Unit height | On the ground or low tee, level with ball |
The MLM2PRO uses dual cameras plus Doppler radar. The radar still needs the same behind-the-golfer positioning as the R10. The cameras handle spin measurement (with marked balls), which takes pressure off the radar for that metric. But placement still matters for ball speed and launch angle.
Full Swing KIT
| Parameter | Specification |
|---|---|
| Unit to ball | 10 feet |
| Ball to screen | 10 feet minimum |
| Total room depth needed | 21 to 22 feet |
| Unit height | Floor level, centered on target line |
The Full Swing KIT needs 10 feet behind the ball — more than any other portable radar unit. That’s because its Doppler radar tracks the full ball flight (not just the first 8 feet like the R10). It also has a built-in 4K camera that captures swing video from behind. The camera angle is optimized for the 10-foot distance.
If your room is under 21 feet deep, the Full Swing KIT is going to struggle. I’ve seen guys buy it for 18-foot garages because “the specs say it works indoors” and then fight with inconsistent numbers for months. It works indoors — if you have the space.
TrackMan 4
| Parameter | Specification |
|---|---|
| Unit to ball | 6 to 9.5 feet |
| Ball to screen | 10 feet minimum |
| Total room depth needed | 18 to 20 feet |
| Unit height | Floor level, precisely centered |
The TrackMan 4 is the gold standard for outdoor radar. Indoors, it’s functional but compromised unless you have 20+ feet of depth. The TrackMan iO (overhead version) is the purpose-built indoor solution.
Camera/Photometric Placement: Exact Distances Per Unit
Camera units are easier to place because they sit beside the ball and don’t need rear clearance. But “beside the ball” has specific measurements, and getting them wrong means missed shots and bad data.
SkyTrak+
| Parameter | Specification |
|---|---|
| Unit to ball (horizontal) | 12 inches from ball on target line side |
| Unit height | Level with the ball on the hitting mat |
| Ball to screen | 10 feet minimum |
| Total room depth needed | 14 to 17 feet |
| Hitting zone | Dead center of mat — off-center by 2 inches and the camera misses |
The SkyTrak+ has a small hitting zone. The camera needs the ball in a very specific spot. If you move the ball 2 inches forward or backward on the mat, the unit can lose it entirely. This is the #1 complaint from new SkyTrak+ owners: “it keeps missing shots.” Nine times out of ten, it’s because the ball isn’t in the sensor’s field of view.
The fix is simple: mark your hitting spot. Use a piece of tape, a Sharpie on the mat, or a divot strip insert. Put the ball in the same spot every time. Once you do that, the SkyTrak+ stops missing shots.
The unit sits beside the ball on the target line. Most right-handed golfers put it on their left side (between them and the target). The manual says 12 inches. I’ve found 10 to 14 inches workable, but 12 is the sweet spot. Too close and the clubhead can hit the housing on the follow-through. Too far and the camera can’t get a clear image of the ball at impact.
Foresight GC3 and Bushnell Launch Pro
The GC3 and Bushnell Launch Pro are the same hardware with different branding and software. Placement is identical.
| Parameter | Specification |
|---|---|
| Unit to ball (horizontal) | 24 inches (2 feet) from the ball |
| Unit height | Level with hitting surface |
| Ball to screen | 8 feet minimum (10 feet safety) |
| Total room depth needed | 12 to 15 feet |
| Hitting zone | 7 x 10 inches — centered on mat |
The GC3 sits 2 feet from the ball — double the distance of the SkyTrak+. That makes it less likely to get hit by a club (the housing is further from the swing path). It also means the hitting zone is larger and more forgiving. The 7x10 inch window is almost twice the area of the SkyTrak+’s.
The GC3 has three cameras (Triscopic system) and a transflective LCD screen. The screen shows your ball speed, club speed, and smash factor right on the unit. You don’t need to look at a phone or PC to get immediate feedback. It’s part of why the GC3 costs three times what the SkyTrak+ does.
One thing GC3 owners get wrong: the unit needs to be perfectly level with the hitting surface. If your hitting mat is thick and the GC3 is on the floor, the cameras are looking up at the ball instead of level with it. Put the GC3 on a low platform or trim your mat so both are at the same height.
Square Golf Launch Monitor
| Parameter | Specification |
|---|---|
| Unit to ball (horizontal) | 16.5 inches |
| Unit height | Level with hitting surface |
| Ball to screen | 8 feet minimum |
| Total room depth needed | 12 to 15 feet |
| Hitting zone | 5.9 x 5.9 inches (small — be precise) |
The Square Golf is the cheapest camera-based unit on the market, and it has the smallest hitting zone. That 5.9-inch window is tight. You need the ball centered. Off by an inch and the camera either misses the shot or reads an edge strike as a center strike (which means wrong ball speed).
The good news: Square Golf includes an alignment app that shows you exactly where the unit needs to be relative to the ball. Use it. Don’t eyeball it.
Square Golf placement is also the most tolerant of limited room depth. The unit needs 8 feet of ball flight (minimum) and sits beside the ball. If your room is 12 feet deep, this is the unit to buy.
Garmin Approach R50
| Parameter | Specification |
|---|---|
| Unit to ball (horizontal) | 18 inches (1.5 feet) |
| Unit height | Level with hitting surface |
| Ball to screen | 8 feet minimum |
| Total room depth needed | 12 to 15 feet |
The R50 is interesting because it’s a camera-based unit in Garmin’s lineup (their other units — R10, G82 — are radar). Three cameras, measured spin, 10-inch built-in display. Placement is similar to the GC3: beside the ball, about 18 inches away.
The R50’s built-in display shows the hitting zone in real time. You can see exactly where the unit sees the ball before you swing. If the ball isn’t in the green zone on the screen, move it. This eliminates the guessing game that other camera units force you into.
Foresight GCQuad
| Parameter | Specification |
|---|---|
| Unit to ball (horizontal) | 22 inches |
| Unit height | Level with ball |
| Ball to screen | 8 feet minimum |
| Total room depth needed | 12 to 15 feet |
| Hitting zone | 14 x 18 inches (massive) |
The GCQuad is the most forgiving camera unit for placement. That 14 x 18 inch hitting zone means you can place the ball almost anywhere on a standard mat and the Quad will read it. It’s also the heaviest portable unit at 7.5 pounds, which means it doesn’t slide around on the hitting surface.
If you have GCQuad money ($12K+) and GCQuad space (12 foot room works), placement is the easiest part of the setup. Level with the ball, 22 inches beside it, and you’re done.
Overhead Placement: Exact Distances Per Unit
Overhead units have the most complex installation but the simplest daily setup. Once they’re mounted correctly, you don’t touch them again.
Uneekor Eye XO and Eye XO2
| Parameter | Specification |
|---|---|
| Mount location | Ceiling, 3.5 feet in front of the tee |
| Mount height | 9 to 10 feet above the hitting surface |
| Ball to screen | 10 feet minimum |
| Total room depth needed | 16 to 17 feet |
| Hitting zone (Eye XO) | 12 x 16 inches |
| Hitting zone (Eye XO2) | 28 x 21 inches |
Uneekor overhead units mount directly above the hitting area, looking down at an angle. The unit goes 3.5 feet in front of the tee position. That means the tee should be 3.5 feet behind the unit’s mounting point.
The ceiling height matters more than room depth for these units. If your ceiling is under 9 feet, the Eye XO’s cameras can’t get enough field of view. At 9 feet it works but the hitting zone shrinks. At 10 feet it’s optimal.
The Eye XO2’s 300% larger hitting zone (28x21 inches vs 12x16) means you can mount it less precisely and still get good reads. But you’re paying $11,000 for that forgiveness.
TrackMan iO
| Parameter | Specification |
|---|---|
| Mount location | Ceiling, 3 feet 3 inches to 3 feet 5 inches in front of the tee |
| Mount height | 9 feet 4 inches minimum (112 inches) |
| Ball to screen | 8 feet minimum |
| Total room depth needed | 14 to 18 feet |
| Hitting zone | Full coverage — no ball positioning constraints |
The TrackMan iO is unique: it uses radar + infrared + cameras in a ceiling-mounted package. It has no minimum distance in front of or behind the ball, which means it works in rooms where floor radar fails and camera units need precise ball placement.
The iO needs 112 inches (9 feet 4 inches) of ceiling clearance. That’s taller than most overhead units. If your garage ceiling is 9 feet flat, the iO won’t fit. At 10 feet it’s comfortable.
The iO’s biggest placement advantage: it tracks the ball from impact through flight regardless of where the ball is on the mat. No small hitting zone. No “ball must be in this exact 6-inch square.” You can drop a ball anywhere on the mat and the iO reads it. This is the single feature that justifies the $14,000 price for some buyers.
ProTee VX
| Parameter | Specification |
|---|---|
| Mount location | Ceiling, 3.5 feet in front of the tee |
| Mount height | 9 feet minimum |
| Ball to screen | 8 feet minimum |
| Total room depth needed | 14 to 16 feet |
The ProTee VX is the most affordable ceiling-mounted unit at roughly $5,000. Placement is similar to the Uneekor Eye XO: 3.5 feet in front of the tee, mounted at 9+ feet. The ProTee VX’s software ecosystem is its differentiator (it runs GSPro natively), not its placement flexibility.
GolfIn IDRA II
| Parameter | Specification |
|---|---|
| Mount location | Ceiling, roughly 3 to 4 feet in front of the tee |
| Mount height | 9 to 10 feet |
| Ball to screen | 8 feet minimum |
| Total room depth needed | 14 to 17 feet |
| Hitting zone | 32 x 18 inches |
The IDRA II has the largest hitting zone of any overhead unit at 32x18 inches. That’s bigger than the Eye XO2. The dual-camera system with AI-powered tracking is generous with ball placement. It also has a rugged metal shell with protective grilles — if your ceiling mount is off by a few inches, the IDRA II is less likely to get damaged by a stray clubhead than a front-mounted unit would.
The IDRA II works without marked balls (it uses AI pattern recognition instead of dimple tracking). This means you don’t need to worry about ball placement relative to camera markers. Place the ball anywhere in that 32x18 inch zone and it reads.
Tilt Specs: The Detail Everyone Gets Wrong
Camera units need to be level. Radar units need to be tilted. Here’s the full table:
| Unit | Tilt Required | Roll Required | Notes |
|---|---|---|---|
| Garmin R10 | 0 degrees (level) | 0 degrees | Bottom edge must be at or above mat height |
| FlightScope Mevo+/Gen 2 | 18 degrees up | 0 degrees | Critical for accuracy — use the tilt stand |
| Rapsodo MLM2PRO | 0 degrees (level) | 0 degrees | Radar + camera; level on ground |
| Full Swing KIT | 0 degrees (level) | 0 degrees | Level, centered, 10 feet behind ball |
| TrackMan 4 | 0 degrees (level) | 0 degrees | Level, precisely centered on target line |
| SkyTrak+ | 0 degrees (level) | 0 degrees | Level with hitting surface |
| GC3 / Launch Pro | 0 degrees (level) | 0 degrees | Level with hitting surface |
| Square Golf | 0 degrees (level) | 0 degrees | Level with hitting surface |
| Garmin R50 | 0 degrees (level) | 0 degrees | Level with hitting surface; display shows zone |
| GCQuad | 0 degrees (level) | 0 degrees | Level with hitting surface |
| Uneekor Eye XO/XO2 | Mount-specific | Mount-specific | Per manual, mount parallel to floor |
| TrackMan iO | Mount-specific | Mount-specific | Per manual, mount parallel to floor |
| ProTee VX | Mount-specific | Mount-specific | Per manual |
| GolfIn IDRA II | Mount-specific | Mount-specific | Per manual |
The Mevo+ tilt is the standout. It needs 18 degrees of backward tilt because the radar beam points upward to track the ball’s trajectory. Without that tilt, the beam misses the ball’s flight entirely or catches it too late. The Mevo+ manual says 18 degrees. Not 15. Not 20. Get an angle finder app on your phone and set it.
For camera units, being level is more important than most people realize. A camera unit tilted 2 degrees forward or backward changes the perspective on the ball at impact. Launch angle readings drift. If your SkyTrak+ is showing consistently low launch angles compared to what you see at the range, check if it’s level first.
Lighting Requirements Per Unit Type
Nobody talks about this at purchase time. It becomes your problem at 9 PM on a Tuesday.
Camera units (SkyTrak+, GC3, Launch Pro, Square Golf, R50): Need consistent, diffused lighting. Direct sunlight blinds the cameras. LED panel lights at 45-degree angles, 3 to 4 feet from the ball, with no harsh shadows. If your garage has a single overhead bulb, the camera unit will miss shots. Two cheap LED work lights from Home Depot ($30 each) will fix this. I’ve seen it a dozen times.
Radar units (R10, Mevo+, Full Swing KIT): Don’t care about lighting. They use radar, not cameras. They DO care about temperature. Radar accuracy shifts about 2 to 3 yards per 20 degrees Fahrenheit. If you practice in a 40-degree garage in January and a 90-degree garage in July, expect different carry numbers with the same swing. It’s not you. It’s physics.
Overhead units (Eye XO, iO, ProTee VX, IDRA II): Most use infrared illumination, which means they don’t care about room lighting at all. You can swing in the dark. The IR system sees the ball and club regardless. This is a genuine advantage for permanent installations.
The lighting issue is why so many first-time buyers get frustrated with camera units. They set up in their garage with existing lighting, the unit misses every third shot, and they assume the unit is bad. The unit isn’t bad. The lighting is bad. Two LED panels will fix it 90% of the time.
Common Placement Mistakes
These are the ones I see most often in Home Golf Hero reader emails and forum threads.
1. Buying a radar unit for a room that’s too small.
It’s the most expensive common mistake in simulator building. A Garmin R10 needs 18 feet of total room depth minimum. A FlightScope Mevo+ needs 19 feet minimum. If you have a 14-foot garage, you cannot use these units. Period. The numbers will be wrong, spin will be estimated badly, and you’ll think you’ve lost 30 yards of carry when really it’s the unit not having enough space to track the ball.
I know you want the $599 option. Everyone does. But if your room is 14 feet deep, buy the Square Golf ($699) or the SkyTrak+ ($1,995). They’ll work. The R10 won’t.
2. Not marking your hitting position.
Camera units need the ball in the same spot every time. If you drop a ball on your mat randomly and swing, the SkyTrak+ or Square Golf will miss 20% of your shots. Put a piece of tape down. Mark the spot. Make it a habit.
3. Placing the monitor on a different surface than the ball.
This is a radar problem and a camera problem. Radar: if the R10 is on a low table and the ball is on the floor, the radar beam geometry is wrong. Camera: if the GC3 is on the concrete floor and the ball is on a 2-inch thick mat, the cameras are looking up at the ball instead of level with it.
Both need to be on the same plane. Same surface height. Zero tolerance.
4. Assuming “close enough” for tilt angles.
The Mevo+ needs exactly 18 degrees. I’ve seen guys say “it looks about right” and then wonder why their launch angle is 4 degrees low. It’s not about the Mevo+. It’s about being precise. Every degree of tilt error changes launch angle readings by roughly half a degree. A 4-degree error in tilt = a 2-degree error in launch angle. That’s 10 yards of carry on a driver.
5. Putting the monitor in the ball rebound path.
Radar units behind the golfer can get hit by balls bouncing off the screen. I’ve seen an R10 get knocked over by a ball that came straight back. Put the radar unit slightly off-center or behind a small protection barrier. Camera units beside the ball can get hit by shanked shots or an overactive follow-through. A protective case ($30-50) is cheaper than a new launch monitor.
The Floor Marker Setup Routine
Here’s the routine that the smartest simulator owners use. It takes 5 minutes once and saves you months of inconsistent data.
- Measure your room depth accurately (not a tape measure eyeball — actually measure from wall to wall).
- Mark your tee position on the mat with tape.
- Mark your ball position on the mat (exact center of the camera’s hitting zone).
- Measure and mark your monitor position on the floor with tape.
- For camera units: mark the spot where the unit sits, plus a line showing the correct orientation.
- For radar units: mark the spot behind the ball and a line showing the center of the target line.
- Every session: put the monitor on the marks, put the ball on the marks, swing.
Floor markers eliminate the #1 source of inconsistent data: you moving the monitor to a slightly different spot every time you set up. The guy who leaves his unit in a permanent spot doesn’t have this problem. The guy who packs it away after every session absolutely does.
If your unit is portable, buy a hard case and keep the floor markers in place. A roll of blue painter’s tape costs $5 at Home Depot. A misread launch monitor costs a lot more.
What This Means for Your Build
Here’s the decision tree in plain English:
If your room is under 15 feet deep: Buy a camera unit. SkyTrak+ ($1,995), Square Golf ($699), or GC3 ($5,249). They sit beside the ball and work in tight spaces. Do not buy radar.
If your room is 15 to 17 feet deep: Camera is comfortable. Overhead is possible. TrackMan iO works here. Floor radar is still marginal.
If your room is 18 to 21 feet deep: Radar works at minimum spec. You can use the R10 or Mevo+ but spin accuracy improves significantly if you can hit 13+ feet of ball flight.
If your room is 22+ feet deep: All options work at full accuracy. Buy what fits your budget and feature needs. The room is not your constraint.
The single most important number in your entire simulator build is not your budget. It’s your room depth. Measure it first. Buy the launch monitor second. Everything else follows from that decision.
Here’s the link to my room depth compatibility matrix if you want the exact product-by-product breakdown. And if you’re still shopping, go measure your garage right now. Tape measure, wall to wall. The answer to “which launch monitor should I buy?” is written on that tape measure.
