How launch monitors track a shot
Every home simulator launch monitor does the same job: it measures the ball (and sometimes the club) around impact and hands those numbers to software that draws the shot on the screen. The technology it uses changes where it has to sit.
Radar (Doppler)
Radar units sit behind the golfer, facing the screen, and follow the ball after it leaves the clubface. They are usually compact and portable and are popular for outdoor practice. Indoors, the ball reaches the screen almost immediately, so the unit relies on its indoor processing, and it needs open space behind the hitting position. Entry radar units commonly sit roughly 6–8½ ft behind the ball (Carl’s Place measuring guide).
Camera (photometric)
Camera-based units photograph the ball — and in premium models the club head — at very high speed right at impact. Because they measure what happens at the ball rather than its flight, they work well in a room where the ball travels only a few yards. Floor cameras sit beside the ball on the golfer’s toe side; overhead cameras are fixed to the ceiling.
Hybrid and overhead systems
Some ceiling units combine radar and cameras. Overhead tracking keeps the floor clear and removes the need for space behind the golfer; Trackman notes that its overhead unit leaves nothing behind the player, whereas its behind-the-ball radar needs about 18 ft from screen to unit (Trackman room guidance).
The six categories
Model names change every year. The categories below are more stable, and they are the same tiers the Cost Planner uses.
Entry portable radar
Lowest cost; sits behind the ball, so it needs more room depth. Highly portable; often usable outdoors.
Midrange portable camera or hybrid
Floor unit beside the ball; strong indoor accuracy for the price. Portable; can move between rooms.
Premium floor-based photometric
High-speed cameras beside the ball; detailed ball and club data. Portable but heavier and more expensive to move.
Overhead camera-based
Ceiling-mounted; nothing on the floor and often easier for both hands. Not portable — permanently mounted.
Rear-mounted or side-mounted system
Ceiling-rear or side mounting keeps the floor clear. Usually fixed.
Premium radar or tour-level system
Professional-grade tracking; behind-the-ball radars need the deepest rooms. Radar units are portable and work outdoors.
Category comparison
The first table covers room fit; the second covers features and the typical price range per tier. Price ranges are planning ranges built from the dated manufacturer examples below — where a product was on sale, the range is anchored on its regular price.
| Category | Mounting | Room depth | Right/left switching |
|---|---|---|---|
| Entry portable radar | On the floor several feet behind the ball, facing the screen. | Radar units commonly sit about 6–8½ ft behind the ball, so they add depth beyond the swing space itself. Indoor ball flight is shorter, so readings depend on room depth. | Usually works for both hands without moving the unit, if the room is wide enough for a centered hitting position. |
| Midrange portable camera or hybrid | On the floor beside the ball, on the golfer’s toe side. | Sits beside the ball, so it does not add depth behind the golfer. | Usually must be moved to the opposite side for the other hand, which also moves the hitting position — plan width for both positions. |
| Premium floor-based photometric | On the floor beside the ball, on the golfer’s toe side. | Sits beside the ball; depth is governed by swing space and screen distance. | Generally repositioned for the other hand; some units detect both sides. |
| Overhead camera-based | Fixed to the ceiling, typically just in front of or above the hitting area. | Adds little or no depth behind the golfer, but needs a specific ceiling height and mounting position. | Many overhead systems support left- and right-handed play without moving hardware; confirm per model. |
| Rear-mounted or side-mounted system | Mounted on the ceiling behind the golfer or on a side wall or floor position. | Rear ceiling units sit within the swing zone above the golfer; confirm mounting height and distance. | Varies by model; some require relocation for the other hand. |
| Premium radar or tour-level system | Behind the ball on the floor or tripod (radar), or overhead for some tour-level systems. | Behind-the-ball radar can require a much deeper room — one manufacturer lists 18 ft or more from screen to unit. | Radar behind the ball works for both hands when the hitting position is centered. |
| Category | Putting | Computer | Typical price |
|---|---|---|---|
| Entry portable radar | Putting support is limited or absent on many entry radar units. | Many work with a phone or tablet; PC software and a paid membership may be needed for simulation. | $500–$900 |
| Midrange portable camera or hybrid | Many support putting with the right software; confirm for the specific model. | Typically pairs with a PC or tablet; some features require a membership. | $2,000–$7,000 |
| Premium floor-based photometric | Often supports putting; confirm with the software you plan to use. | Usually requires a capable gaming PC for simulation software. | $5,000–$20,000 |
| Overhead camera-based | Commonly supports putting within the camera zone. | Usually requires a gaming PC and Ethernet or PoE connection. | $6,000–$17,000 |
| Rear-mounted or side-mounted system | Varies by model. | Usually requires a gaming PC. | $5,000–$12,000 |
| Premium radar or tour-level system | Varies by system and software. | Requires a capable PC and typically an annual software subscription. | $5,000–$26,000 |
Ball data, club data, and putting
Ball data
Ball speed, launch angle, launch direction, and spin are the foundation of every simulated shot. Nearly every unit in every tier reports them, but how spin is measured, and how consistently it is read indoors, differs between technologies and models. If you mostly want to play simulated rounds, solid ball data matters more than anything else.
Club data
Club speed, path, face angle, angle of attack, and impact location are what help you understand why a shot curved. Premium camera and overhead systems tend to report more of them. On several midrange units, some club data sits behind a paid membership tier rather than coming with the hardware — check the membership page before you assume a feature is included.
Putting
Putting support varies more than any other feature. Many entry radars do not read putts well; many camera and overhead units do, but only within their camera zone and only in software that supports it. If putting matters to you, confirm it for the exact model and the exact software, and plan a hitting surface or turf that rolls reasonably true.
Room depth, hitting zone, and handedness
Room-depth requirements
Total depth is the swing space behind the ball, the distance from the ball to the screen, the space behind the screen, and — for behind-the-ball radar — the unit itself. Retail guidance suggests about 18–20 ft of depth, at least 10 ft from screen to ball, and about 7 ft behind the ball for the swing (Carl’s Place). A radar that sits 8 ft behind the ball pushes that depth further. Floor cameras beside the ball and overhead units add no depth behind you.
Hitting-zone size
Camera and overhead units only see a defined area. A small zone means teeing up in nearly the same spot every shot; a larger zone is more forgiving and matters more for putting and chipping. For example, Uneekor lists a hitting zone of 14 × 12 in for its rear-mounted EYE XR and a larger zone for its front-overhead model; check the zone size for any ceiling unit before you finalize the mat position (Uneekor EYE XR).
Right- and left-handed switching
A floor camera sits on the golfer’s toe side. For a left-handed golfer, it has to move to the other side of the ball, and the hitting position usually shifts with it. That is fine in a wide room and a problem in a narrow one: retail guidance suggests 14 ft or more for a centered hitting position that serves both hands, and 10 ft as a minimum with an offset single-handed position (Carl’s Place). Radar behind the ball and many overhead systems track both hands from one centered spot; confirm this for the specific model.
See the room size and ceiling height guide for the full measurement method.
Mounting, portability, and indoor vs. indoor/outdoor use
Mounting
Floor units need a level, repeatable position — many owners mark it on the mat or turf. Ceiling units need a solid mounting point at a specified height and distance from the ball, a cable run to the computer (often Ethernet or power-over-Ethernet), and calibration after installation. Uneekor, for instance, lists an optimal 10 ft mount height for its ceiling units (Uneekor EYE XO2). Ask a qualified professional about the ceiling structure before mounting anything overhead.
Portability
Portable radars and floor cameras can come out to the range or move between rooms. Moving a unit means re-aligning it each time, which is a small but real cost in a shared or multipurpose space. Ceiling units are permanent; that is a benefit in a dedicated room and a drawback if you might move house soon.
Indoor only or indoor/outdoor
Radar is naturally suited to outdoor use with full ball flight. Camera units read impact, so they suit indoor rooms; many floor cameras can also be used outdoors. Overhead and rear-mounted units are indoor only. Decide honestly how often you will take it outside — portability you never use still shapes the room you need.
Software compatibility, memberships, and computers
Software compatibility
Most launch monitors ship with their own app or range software, and many connect to third-party simulation programs. Compatibility is model-specific and sometimes requires a particular membership level on the launch monitor side. GSPro, for example, notes that some launch monitors need their own paid subscription to connect (GSPro). Confirm both halves before buying.
Memberships
Many units sell annual plans that unlock courses, club data, or third-party connections. On the access date, published plans ranged from a free basic tier up to about $600 per year for midrange brands, and $700–$1,100 per year for Trackman’s iO home subscriptions (sources in the total cost section).
Computer requirements
Entry radars often run on a phone or tablet, but full simulation software generally needs a Windows gaming PC. GSPro lists Windows 10 or 11 with an RTX 3060-class graphics card as its 1080p minimum and an RTX 3080 or better for 4K (GSPro system requirements). Overhead systems typically also need a wired network connection from the ceiling to the PC.
Support and warranty
Warranty length, what it covers, and how repairs or recalibration work vary by manufacturer and by where you buy. A ceiling unit that needs service means someone on a ladder; a floor unit can be boxed and shipped. Read the terms on the manufacturer’s site before purchase, keep proof of purchase, and ask whether buying through a retailer changes who handles support.

Which category to consider
There is no single right launch monitor — only one that suits your room, players, and budget. Start from the constraint that is hardest to change.
A tight room (short on depth and width)
Consider: Midrange portable camera or hybrid; Premium floor-based photometric.
Floor units beside the ball add nothing behind the ball, so the room only has to hold the swing and the screen distance. The trade-off is that they usually move to the other side of the ball for the opposite hand, so width has to cover both hitting positions if you need both.
You want to take it to the range or another room
Consider: Entry portable radar; Midrange portable camera or hybrid; Premium radar or tour-level system.
Portable radars and floor cameras pack up in minutes. Behind-the-ball radars need about 6 ft–8 ft 6 in behind the ball (entry units) or about 8 ft–10 ft behind the ball (premium units), so the indoor room still has to be deep.
Right- and left-handed golfers share the room
Consider: Entry portable radar; Overhead camera-based; Premium radar or tour-level system.
Entry portable radar, Overhead camera-based, Premium radar or tour-level system can usually track both hands from one centered hitting position. Floor cameras beside the ball generally need to be moved or the hitting position mirrored, which costs width. Confirm dual-handed support for the specific model.
A premium, permanently integrated room
Consider: Overhead camera-based; Rear-mounted or side-mounted system.
Ceiling units keep the floor clear and are less likely to be kicked or moved, which helps calibration. They need a ceiling-mount position in the right place — the planner screens for at least 9 ft 6 in and prefers 10 ft — plus a capable PC and a wired connection.
Limited room depth
Consider: Midrange portable camera or hybrid; Premium floor-based photometric; Overhead camera-based.
Midrange portable camera or hybrid, Premium floor-based photometric, Overhead camera-based add nothing behind the ball. Avoid behind-the-ball radar if depth is the limiting dimension: entry radars sit about 6 ft–8 ft 6 in behind the ball, and one manufacturer lists 18 ft or more from screen to unit for its tour-level radar.
Indoor and outdoor flexibility
Consider: Entry portable radar; Premium radar or tour-level system.
Radar measures the ball in flight and is naturally suited to outdoor use with a full ball flight. Indoors, the ball hits the screen within a few yards, so readings rely more on the unit’s indoor mode — and the room has to be deep enough for the unit behind you.
Check my room against each tier
Total cost of ownership
The purchase price is the visible part. Over three to five years, recurring costs can match or exceed it. Plan for three layers:
1. One-time hardware price
Use the regular price, not a temporary sale, when you budget — the tier ranges in the comparison table above do this.
2. Memberships and software
- SkyTrak plans listed from $99.99 to $599.99 per year (SkyTrak membership plans).
- Uneekor: free Player tier; Pro $199, Champion $399, Ultimate $599 per year (Uneekor EYE XR page).
- Bushnell Launch Pro: free tier, Silver $199 and Gold $599 per year, with course passes $295–$595 per year (Bushnell Launch Pro).
- Rapsodo Premium membership: $199.99 for one year (Rapsodo subscriptions).
- Trackman iO: Home $700 per year, Home Complete $1,100 per year (Trackman iO subscriptions).
- Third-party software such as GSPro: $250 per year, in addition to any launch-monitor plan needed to connect (GSPro).
3. The computer
If your software needs a Windows gaming PC, budget for one that meets its published requirements — GSPro’s 4K recommendation calls for a much stronger graphics card than its 1080p minimum (GSPro). The cost guide covers PC allowances.
Before you buy
Launch monitor pre-purchase checklist
- Confirm the unit’s placement (behind, beside, or above the ball) and measure that distance in your room.
- Confirm which hand(s) it tracks from one position, and whether it must be moved to switch.
- For ceiling units, confirm the required mount height and distance from the ball, and how the cable reaches the PC.
- Check which data needs a paid membership — club data, course play, and third-party software connections are common paywalls.
- Check that the simulation software you want supports this model, and whether that software needs its own subscription.
- Check the software’s PC requirements (graphics card, memory, Windows version) before you budget for the computer.
- Confirm putting support in the software you will actually use.
- Read the warranty terms and how service or calibration is handled.
- Add up the purchase price plus three to five years of memberships and software before comparing tiers.
- Plan to test a controlled full swing in the finished space before relying on the setup.
Safety note: no placement figure guarantees a safe swing. Test a controlled full swing with your longest club in the finished space, and involve qualified professionals for any ceiling mounting, electrical, or structural question.
