Know your numbers.
Independent buyer guides for golf launch monitors and home simulators — compared on the numbers that actually decide the buy: what a unit truly measures versus what it calculates, the data method (Doppler radar or photometric camera), the published accuracy band, and which sim platforms it drives. Plus a measured-vs-calculated comparator and a sim space planner that tell you the truth before you spend. Written by a golfer who built a swing change on numbers he could not trust, so you don't have to.

Choose your path
Three doors. Where you start depends on whether you are building your first sim, want to know what a unit actually measures, or just need to know it will fit your garage.
I'm building my first home sim
Start with the R10-as-home-sim build guide. The four price tiers in plain English, what the unit measures vs calculates, the full cart-stack order, and why ceiling height matters more than budget.
Open →I want to know what it really measures
Use the Measured-vs-Calculated comparator. Filter by must-measure-spin, budget band, indoor vs outdoor and GSPro/E6 compatibility — and see each parameter labelled measured, calculated or not-captured.
Open →I need to know if a sim fits my garage
Use the Sim Space & Ceiling-Height Planner. Enter room length, width and ceiling height plus your dominant hand, and get whether a full-swing enclosure fits and the build-killer ceiling flag.
Open →Where to start
By Budget Tier
Entry portable (sub-$1k), mid prosumer ($1k–$5k) and full enclosure-grade ($5k+) — what each tier actually measures vs estimates, and where the price jumps buy you real data.
View guides →By Data Depth
What each unit measures vs calculates — ball speed, club speed, spin (measured vs derived), launch angle, smash factor, carry. Doppler radar vs photometric camera, and the published accuracy bands.
View guides →Sim Compatibility
Which monitors drive GSPro, E6 Connect, TGC and The Golf Club; projector and impact-screen pairing; and the indoor space and ceiling-height requirements that quietly kill more garage builds than budget does.
View guides →Enclosures & Accessories
The build kit behind every monitor — enclosures, hitting nets, mats, impact screens, projectors and mounts. What to buy first and how it stacks onto the launch monitor.
View guides →The four guides most readers start with
Best golf launch monitors under $1,000
Affordable portable units compared on tech type, what they measure vs calculate, indoor/outdoor use and sim compatibility — the cleanest way into the data.
Best launch monitors for measured spin
Units that actually measure spin (not calculate it from ball speed) compared on data method, parameters and accuracy band — the heart of the brand.
Best budget golf simulators
R10, Phigolf and more compared on what they measure, sim-platform support and the space they need — the buy-side companion to the pillar.
Best golf simulator enclosures
Enclosures, impact screens, mats and nets compared on type, size, material and compatibility — the natural cart-stack behind every monitor.

Who writes here
Launch Monitor Data is founded and written by Danny Hollis, a mid-handicap golfer outside Columbus, Ohio who built a garage simulator to practise through the long Ohio winter. He started the site after learning the hard way that his first, cheap launch monitor was calculating his spin numbers instead of measuring them — he built a swing change on data he could not trust, and nearly bought a unit and screen his garage ceiling could never swing under. Some articles also come from rotating contributors — longtime home-sim builders and club golfers. Product comparisons stay neutral and spec-led — no fabricated hands-on accuracy testing.

Launch Monitor Data sits inside a small family of spec-led sports-gear sites. If your off-season runs on more than golf, the same numbers-first approach powers our coverage of pickleball paddle specs and a starter guide to disc golf discs and gear.
