Sometimes the best upgrades are the ones that don’t cost you anything extra.
That’s exactly what Rapsodo has delivered with the addition of attack angle and swing path measurements to its MLM2PRO launch monitor. A simple app update (v 2.17.5) and firmware refresh (3.8.59) unlocks two metrics that have traditionally been reserved for significantly more expensive systems.
For golfers already using the MLM2PRO, it’s like finding twenty bucks in your jacket pocket. For those considering a launch monitor purchase, it further solidifies the MLM2PRO’s position as the best value in consumer launch monitors under $1,000.
What are attack angle and swing path?
Attack angle measures whether your club is moving upward or downward at impact, expressed in degrees. Positive numbers indicate an upward strike while negative numbers show a downward blow. With a driver, most golfers benefit from a slightly upward attack angle (around +2 to +5 degrees) to maximize distance. With irons, a slightly downward attack angle (around -2 to -4 degrees) helps create solid contact and proper trajectory.
Swing path tracks the direction your clubhead is traveling relative to your target line at impact. A path of 0 degrees means you’re swinging directly down the target line. Positive numbers indicate an inside-out path (good for draws), while negative numbers show an outside-in path (often associated with fades and slices).
Both metrics provide crucial insights that can finally explain why that driver swing that felt identical to yesterday’s produces dramatically different results, or why your 7-iron sometimes flies 160 yards and other times barely reaches 145.
How Rapsodo captures the data
The MLM2PRO’s hybrid approach which combines radar (Doppler) and photometric (camera) components enables these new measurements without requiring any additional hardware or fiducials (stickers) on the clubface. The system tracks the club throughout the swing by combining data from the radar unit with footage from the Impact Vision Camera.
Rapsodo tested more than 10,000 shots during development and claims accuracy within 0.97 degrees of a Foresight GCQuad for attack angle and 0.76 degrees for swing path. While variance compared to TrackMan will be wider, that’s primarily due to differences in how the devices measure than accuracy itself.
For most golfers, absolute precision matters less than consistency. You’re typically seeking improvement rather than an exact number. You’ll likely be more concerned with achieving a more positive attack angle with your driver or a more neutral swing path to reduce that persistent slice. As long as your baseline measurements are reliable, you can track meaningful progress.
The value proposition gets even stronger
At less than $1,000, the MLM2PRO was already inarguably the best value in consumer launch monitors. You could spend another $1,000 and maybe not do better. (You could definitely do worse.) These new metrics strengthen that position significantly.
The system’s accuracy remains surprisingly good given the price point and now it provides data that was previously all but exclusive to much more expensive units. The trade-off is a slightly reduced hitting area, which isn’t particularly uncommon when tracking head data. Most users will find the compromise worthwhile.
What makes this update particularly appealing is its seamless integration: no additional purchase required, no new setup procedures to learn, no new costs. It’s simply more capability from the tools you already own.
From guesswork to targeted improvement
Having access to attack angle and swing path data transforms practice sessions from hopeful repetition into targeted improvement. That driver swing that felt pure but produced a weak pop-fly? Attack angle data will show you were probably coming down too steeply. Your iron shots that occasionally decide to fly shorter than expected? Swing path might reveal you’re coming over the top when fatigue sets in.
The data becomes especially valuable when combined with the MLM2PRO’s existing ball flight metrics. Understanding not just where your ball goes but why it goes there accelerates improvement in ways that feel-based adjustments alone simply can’t match.
For golfers working with instructors, these metrics provide objective feedback that separates, “I think you’re doing this” from “here’s exactly what you’re doing.” It’s the difference between speculation and evidence, hope, and actual knowledge.
The bottom line
Rapsodo’s decision to roll out these new metrics without increasing the price demonstrates confidence in their core product and respect for existing customers. In an industry where upgrades often mean upgrade fees, this approach feels refreshingly customer-focused.
The MLM2PRO continues to punch well above its weight class, now delivering professional-grade swing analysis at a fraction of traditional costs. For golfers serious about improvement but realistic about budgets, it’s becoming increasingly difficult to justify spending significantly more on a launch monitor.
