Data & Accuracy

The MLM2PRO™ provides 13 metrics including:  

  • Ball Speed (measured)  
  • Club Speed (measured) 
  • Smash Factor  
  • Launch Angle (measured) 
  • Launch Direction (measured) 
  • Carry Distance  
  • Total Distance  
  • Spin Rate (measured) 
  • Spin Axis (measured) 
  • Descent Angle  
  • Side Carry  
  • Apex  
  • Shot Type  

Through our partnership with Callaway, we specially engineered balls using Callaway’s TruvisTechnology. These new golf balls are called, Callaway® RPT™ Chrome Soft X® Golf Balls and are designed with RapsodoPrecision Technology (RPT™) so the MLM2PRO™ can track the in-flight spin rate and spin axis of the ball. This allows you to receive spin measurements within 1% of the accuracy of high-priced launch monitors.

Callaway® RPT™ Golf Balls arerequired to show spin numbers.

The MLM2PRO™ is designed to sit 6.5-8.5 feet directly behind the ball aimed down the target line. 

A little more than 14 total feet is needed. First, 8 feet is needed from ball to the net. Then, the MLM2PRO™ requires another 6.5-8.5feet behind the ball.Taller players may need to place the device further back to capture their entire swing video.

Elevation affects distances, trajectory and descent angle  

  • The higher the elevation, the less dense the air is. Because of this, there is less drag force on the ball (resistance) allowing it to maintain speed during flight, resulting in greater distance.   
  • General rule of thumb is every 1500 ft of increased elevation = ball will travel 3-5% further  

A range ball vs premium ball will also affect your data. A range ball will fly shorter, generate less spin, and not produce as much ball speed as a premium golf ball.   

Within the MLM2PRO™ App, you can adjust your settings to account for elevation and ball type to ensure your data is as accurate as possible.  

No, MLM2PRO™ will not capture data with foam/plastic balls.  You will want to use a Range or Premium Golf Ball, and with MLM2PRO™ it is recommended that you use the included Callaway®RPT™ Chrome Soft X™ Balls to take advantage of all the metrics that can be captured (Spin and Spin Axis).

If your mobile phone or tablet has an active internet connection (Wi-Fi or Cellular), shots will sync to the cloud during the session. If you do not have an active internet connection, shots will begin syncing once your phone/tablet connects to the internet (the MLM2PRO™ App must stay open during the sync process). 

Additional golf balls can be purchased on the Rapsodo website for $65/dozen.

You can export videos with shot trace to share on social media, share with friends, or send them to an instructor!  Currently, we don’t offer the ability to export data from a session in CSV or similar format.


An internet connection is not required to use the MLM2PRO™, but it does provide the best range experiences.An internet connection is needed to sync the shots from your session, access Rapsodo Courses, Partner Simulation, Combines and Insights reports.

No. In order for you to get accurate data, you will need to use a real golf ball. The MLM will not trigger properly if using a wiffle or foam practice ball.

Yes, the MLM will only be able to provide data in well-lit environments.

High winds can affect the distances as we do not account for adverse conditions. Overheating can affect the MLM if your iPhone/iPad is placed in direct sunlight. If your iOS device starts to overheat, you will receive an alert informing you. Your MLM will still track data and record each shot for review in Sessions but instant video feedback during the session is disabled to help cooldown your device.

*Please note that if you have any credit cards or a magnetic case on your iPhone, it may cause interference with your iOS gyroscope. Please remove the case from your phone before starting your session.

MLM analyzes the initial flight of the ball to calculate trajectory and distance by using radar/camera technology. Golf Laboratories has conducted product comparison testing. See how the MLM compares to Trackman and to Flightscope Mevo.

Place the MLM 6-8ft behind you. When addressing the ball, look back at your iOS device to ensure you see your body in the “Player Area” and the ball in the “Ball Area”. The alignment line in between the two boxes and should be aimed parallel to your target line.

The MLM is tracking the actual ball velocity, launch, and initial trajectory. This data will vary with the type and quality of the ball. Range balls are often harder than standard balls which would result in high velo and higher launch angles. But the resulting distance and trajectory will be accurate for a range ball.

If you are hitting shots and the LED on the MLM turns from green to blue and back to green but no data shows:

Ensure the MLM is aligned 6-8 feet behind the ball and aimed down the target line

Check to make sure your iOS device is sitting on the MLM slot with the screen facing you

Ensure you do not have a magnetic case on your iOS device

The MLM does not take wind, weather, slope, or elevation into consideration. It assumes you are using a premium ball at 70 degrees with no humidity and assumes you are at sea level.

1. Open the MLM app and click the ‘Home’ tab

2. Tap on the session you wish to go back to

3. Search for the shot you wish to share. The list is sorted by the sequence you practiced. You can easily sort it by club type, distance, etc., just tap on the column description or club.

4. Once you found the shot you wish to share, slide from right to left on the favored shot and tap on the camera icon. It will open and play the video recording of that shot.

5. Once the video is played back a share icon will appear on the bottom right (U with an arrow up) the export process will take a few seconds.

6. This will open a menu which allows you to save the video on your phone in Photos or you can share it with your friends via message or other social media platforms.

The MLM is only compatible with iOS Devices that meet our minimum requirements.

The Public setting will qualify you for having your video appear on the Explore page of the application. The Private setting will not qualify you to show up on the Explore page.

You are able to drop a pin within the driving range that you are hitting at. Then you are able to look back on the shots and see exactly where they were on the range from a birds eye view map.

No, the only export feature is with the video with overlay which can be saved to your iPhone/iPad and shared to Twitter, Instagram, Facebook or other social media platforms.

Please remember that the auto club recognition feature only works outdoor for now, it does not work indoors. It might work better on irons, but on drivers and woods the numbers are more to the corners of the clubs, so please try not to show the club to the camera too close, it needs to focus on the numbers on the club.

Please make sure;

You have good lighting on the camera, not too bright and not too dark.

You fit the club head in the frame.

You keep the club head vertical.

Auto club recognition is disabled on net mode due to the lighting. As people are hitting at home or at their garage, the lighting is not sufficient for the phone’s camera to read the tiny details on the clubs and recognize them.

Distances are reported in “Carry”, however you have the option to select “Total” distance for drivers and woods. Here is how to change the driver and wood distance:

Open MLM app > Profile > App Settings > Driver wood settings (Carry/Total)

***This is the same on Outdoor and Indoor modes.

Golf Insight

To identify trends in your game, we need a reliable data set of six or more shots. The more shots you take with each club, the more accurate your averages will be.

Grayed out shots represent outliers from your session. Removing outliers from Insights gives you a better chance to clearly visualize trends from your session. We will only remove shots that are extremely offline, short or long based on the entire data set for each club. If you decide to delete a shot, outliers will recalculate.
