Rapsodo MLM2PRO vs SkyTrak ST MAX
Buy the Rapsodo MLM2PRO (under $1,000) if you want shot-tracer video, measured spin, and a unit that handles a tight indoor space but still travels to the range. Buy the SkyTrak ST MAX ($2,000+ tier) if you're building a real home golf simulator you'll play serious virtual rounds in: its photometric indoor accuracy and simulator-software ecosystem are what you're paying for. The MLM2PRO wins on price, portability, and video; the ST MAX wins on sim-grade indoor numbers and dedicated simulator software. Decide what you're actually building before you decide which to buy.

The short answer
These aren't really the same kind of device. The SkyTrak ST MAX is a sim-first unit built for a permanent indoor bay, while the MLM2PRO is a portable practice tool that also does casual home simulation. People cross-shop them because both read the ball at impact with cameras and both can "run a simulator," but they're aimed at different golfers. The decision really comes down to two questions: Is this unit going to live in one fixed spot, or travel with you? and Is serious simulator golf the goal, or is it practice with video?
A note on names: SkyTrak's current unit is the ST MAX. On the manufacturer's published spec pages the ST+ (SkyTrak+) shares the same measured-data split, so this comparison covers the family; our Data Points Index lists both rows.
Rapsodo MLM2PRO: the portable video & spin pick
Rapsodo MLM2PRO
Best for Video, Spin & Fixed-or-Portable Use
Verdict: Pick the MLM2PRO for tight indoor practice, measured spin, and shot-tracer video in a unit that also goes to the range.

The MLM2PRO pairs Doppler radar with two cameras: one that records your swing and ball flight for shot-tracer replays, and a high-speed impact camera that reads the ball at the moment of contact. Because the cameras read the ball at impact, it doesn't need the long tracking runway that radar units want, so it is far more forgiving of a short garage bay. With the Premium membership it supports simulator play, including integration with third-party sim software and Rapsodo's own courses and ranges. It isn't a $2,000+ photometric sim engine, but for casual home simulation under $1,000 it's a capable setup, and it is the pick if you also want to take the unit to the range.
✓ Pros
- Automatic shot-tracer video on every swing
- Measured spin rate and spin axis (not estimated) with RPT balls
- Camera-based tracking handles tight indoor rooms better than radar
- Portable and battery-powered; works at the range too
- A fraction of the ST MAX's price tier
✗ Cons
- Full data, including spin, requires the recurring Premium membership
- RPT balls are a consumable cost for measured spin
- Not a sim-grade photometric engine like the ST MAX
- Club-path style delivery data is thinner than premium photometric or radar systems provide
SkyTrak ST MAX: the home-simulator pick

For a dedicated garage or basement simulator, the SkyTrak ST MAX is the long-time favorite. SkyTrak attributes its ball data (carry, total distance, ball speed, back spin, side spin, descent angle, side angle, launch angle, shot shape) to the photometric camera system and its club data (club head speed, smash factor, club path, face angle, face-to-path) to the Doppler radar. Its camera system reads the ball at impact, so it needs minimal space behind the ball and fits a roughly 12-foot-deep bay with about 9 feet of ceiling. It pairs with the popular simulator platforms for full virtual rounds. If you want a bay you'll genuinely play in, not just hit into, this is the unit that holds up.
✓ Pros
- Sim-grade indoor accuracy in tight spaces
- Works with leading simulator software (GSPro, E6, etc.)
- Ball data and club data each attributed to a dedicated sensor system
- Built for a permanent, play-serious home setup
✗ Cons
- $2,000+ tier, well above the MLM2PRO
- Needs a PC, mat, net/screen and ideally a projector
- Best simulator play is subscription-based
- Not a grab-and-go range tool
Head-to-head: where each one wins
Price & value
The MLM2PRO sits under $1,000; the ST MAX is the $2,000+ tier before you add a PC, mat, net or screen, and projector. If you want practice data, video, and casual sim play, the gap buys you little. Value goes to the MLM2PRO.
Indoor accuracy in a permanent bay
Both read the ball at impact with cameras, so both are forgiving of a short room. But the ST MAX is built around sim-grade indoor numbers with a dedicated photometric system for ball data and radar for club data. Indoor accuracy goes to the ST MAX.
Portability & the range
The MLM2PRO is battery-powered and portable, so it works at the range as well as in the garage. The ST MAX is built for a fixed indoor bay and is not a grab-and-go range tool. Portability goes to the MLM2PRO.
Video & spin
Automatic shot-tracer video is the MLM2PRO's whole pitch; nothing on this site documents tracer video for the ST MAX. Both measure spin optically: the ST MAX via its photometric cameras, the MLM2PRO via its impact camera with marked RPT balls and the membership. Video goes to the MLM2PRO; spin is a tie on method, with the ST MAX not needing marked balls stated as a requirement.
Simulator software & subscriptions
The ST MAX pairs with dedicated simulator software such as GSPro and E6, typically subscription-based. The MLM2PRO supports simulator play with the Premium membership, including third-party sim software and Rapsodo's own courses and ranges. For serious simulator golf, the ST MAX's ecosystem is the purpose-built choice. Either way, budget for a recurring cost on top of the hardware.
Which should you buy?
- Buy the Rapsodo MLM2PRO if: you practice in a tight indoor space, you want automatic shot-tracer video and measured spin, you want a unit that also travels to the range, and you've priced in the Premium membership.
- Buy the SkyTrak ST MAX if: you have (or are building) a permanent indoor bay, you want to play serious simulator golf in GSPro or E6, and sim-grade indoor accuracy is the priority.
The biggest mistake is buying up for a use-case you don't have. If you're not sure you'll build a real bay, start with the MLM2PRO: you'll learn what you actually want, and the ST MAX will still be there later.

The SkyTrak ST MAX. It is a photometric (camera) unit with added radar, built to read the ball at impact in a permanent indoor bay, and it pairs with dedicated simulator software such as GSPro and E6. The MLM2PRO supports simulator play with the Premium membership, including integration with third-party sim software and Rapsodo's own courses and ranges, but it isn't a $2,000+ photometric sim engine like the ST MAX. If serious simulator golf is the goal, the ST MAX is the purpose-built choice.
It depends on what you're building. If you want a true home golf simulator you'll play serious virtual rounds in, the ST MAX's indoor accuracy and simulator-software ecosystem justify the price. If you want shot-tracer video, measured spin, and a launch monitor that behaves well in a tight indoor space but also travels to the range, the MLM2PRO (under $1,000) is one of the strongest options in its class. Don't pay ST MAX money for MLM2PRO use-cases.
The Rapsodo MLM2PRO. It is portable and battery-powered, so it works at the range as well as indoors. The SkyTrak ST MAX is built for a fixed indoor bay and is not a grab-and-go range tool; plan for a net or impact screen, a mat, and a PC to complete the bay.
Both have recurring-cost angles. The MLM2PRO works without a plan for basic metrics, but measured spin, spin axis, the full shot-vision video toolset, and simulator play require the paid MLM2PRO Premium membership. The ST MAX unlocks its full value through simulator software that is typically subscription-based. Add the recurring cost to the sticker price when you compare.
Both measure spin optically, with a difference in how. SkyTrak attributes back spin and side spin to the ST MAX's photometric camera system. The MLM2PRO's impact camera measures spin rate and spin axis when you use Rapsodo's marked RPT balls with the membership; on unmarked balls its spin falls back to estimation.
On the manufacturer's published spec pages they share the same measured-data split: ball data (carry, total, ball speed, back spin, side spin, descent angle, side angle, launch angle, shot shape) under the photometric camera system, and club data (club head speed, smash factor, club path, face angle, face-to-path) under the Doppler radar system. This site's price-band guidance treats the family as the $2,000+ tier. Beyond that attribution, this site has not documented further differences between the two models.
