Change keeps disappearing
A position may look better on video, yet the old delivery returns when speed rises. Measurement can show what changed elsewhere in the system.

Why measure
When the Ball Flight Shows the Effect, but Not the Cause
A golfer can see a poor strike, unwanted curvature or lost speed without knowing which part of the movement is actually responsible. A 3D assessment is useful when the question requires several evidence streams to be compared at the same moment.
Speed feels expensive
The golfer can create effort but not proportionate club speed. Force, sequence and delivery can be examined together rather than assumed.
Advice conflicts
Different visual diagnoses have produced different fixes. Synchronized data helps establish which feature is relevant to the actual shot outcome.
The miss lacks an explanation
Face, path, strike or low-point patterns may vary. The assessment works backwards from the measured result to the movement associated with it.
The aim is not to produce the largest report. It is to determine what the evidence supports, what remains functional and which priority is most useful to train next.
Three connected views
What the Studio Systems Measure
Each system answers a different part of the question. Their value comes from synchronisation and interpretation—not from treating any single number as an ideal every golfer must copy.
TrackMan 4
Club delivery and ball flight.
TrackMan can measure parameters such as club speed, attack angle, club path, face angle, dynamic loft, spin loft, impact location, ball speed, launch, spin and carry.
- What the club delivered at impact
- What the ball did as a consequence
- Whether a change altered the intended outcome
SwingCatalyst 3D Motion Plate
Pressure and ground reaction force.
The plate measures pressure beneath the feet and ground reaction force in three dimensions, allowing the timing and direction of force to be viewed alongside the swing.
- How pressure moves during the motion
- Vertical and horizontal force components
- How the force pattern relates to the measured delivery
Full-Body 3D Motion Capture
Movement through time.
Three-dimensional body mapping provides a view of how segments such as the pelvis and thorax translate and rotate, and how their movement is organised through the swing.
- Segment motion and timing
- Posture and rotational organisation
- Movement differences between successful and unsuccessful shots
Technology is selected, not performed for theatre. Some questions need all three systems. Others can be answered with a narrower capture. The assessment should gather only the information needed to make the next decision clearer.
From numbers to a coaching decision
What Linked Data Can Help Clarify
The same visible swing feature can emerge for different reasons. The job is to compare the shot, club, ground and body data before deciding what should—or should not—change.
| Observed problem | Evidence compared | Question the assessment explores |
|---|---|---|
| Unstable start line or curvature | Face angle, club path, face-to-path, impact location and body motion | Which measured variable is changing first, and what movement is associated with that change? |
| Inconsistent low point or strike | Attack angle, low point, impact location, pressure movement and segment motion | Is the strike pattern linked to setup, movement timing, force use or a combination? |
| Club speed below the golfer's potential | Club speed, swing radius, force-time data and body-segment velocities | Where is speed being created, interrupted or reorganised—and what does the golfer naturally use well? |
| Movement changes at higher effort | Lower- and higher-speed captures across body, ground, club and ball data | Which part of the organisation changes as intent rises, and which elements remain stable? |
| A technical change will not consolidate | Baseline capture, coached intervention, re-test and the golfer's reported feel | Did the intended movement change, did the delivery improve, and is the cue producing the response claimed? |
These are examples of questions, not preset diagnoses. A force pattern, body position or sequence is not labelled good or bad without considering the golfer, the task and the resulting shot.
Assessment structure
How the Session Works
The session moves from context to capture, from capture to interpretation, and from interpretation to a practical test. The golfer should understand the conclusion, not merely be shown the data.
Establish the question
Discuss the ball flight, strike pattern, coaching history, physical considerations, current feels and what changes under speed or pressure.
Build a baseline
Record representative shots before making a correction. The relevant systems are selected according to the problem being investigated.
Interpret and test
Compare body, ground, club and ball information. Introduce one useful intervention and re-measure rather than assuming it worked.
Define the next phase
Leave with the relevant explanation, a narrow set of priorities and a practice structure. Follow-up is recommended only where it serves the plan.
What to bring
- Your normal golf shoes and the clubs relevant to the problem
- A short description of your common strike and ball-flight pattern
- Current drills or cues so useful work is not discarded automatically
- Any guidance already provided by a qualified healthcare professional
What you should leave with
- A plain-language explanation of the evidence that matters
- Clarity about what remains functional and should be protected
- One or two priorities rather than a complete swing overhaul
- A way to practise and evaluate whether the change is consolidating
The wider framework
Measurement Sits Inside the Clarity Method
The 3D systems measure movement and delivery. They do not, by themselves, explain why a golfer loses access to a movement under consequence or what that performance means to the golfer. Those questions belong to the wider coaching framework.
Biomechanics
How the golfer moves, uses force and delivers the club. This is where 3D capture, force-plate information and TrackMan data provide objective evidence.
Performance Psychology
How attention, intention, pressure, trust and emotional state influence access to the movement. These factors are coached, not inferred from a graph.
Performance Identity
How the golfer's self-story and the meaning attached to success or failure can shape decisions, effort and behaviour when the game matters.
Biomechanical data answers an important part of the problem, not the whole of the golfer. The Clarity Method keeps objective measurement connected to how the movement will be learned, practised and used.
A precise scope
What This Assessment Is—and What It Is Not
This assessment is useful if you:
- Want objective evidence rather than another visual opinion
- Have a persistent strike, flight or speed question
- Want to understand how movement relates to delivery
- Are prepared to train a small number of priorities after the session
- Value explanation and re-testing over a technology demonstration
This assessment is not:
- A promise that every available system will be used
- A search for one model swing that every golfer must copy
- A guarantee of speed, consistency or transfer within a fixed time
- A medical diagnosis, rehabilitation service or clearance to play
- An online 3D capture presented as equivalent to the studio
Studio or remote
3D Capture Requires the Studio
The combined assessment is completed in person because the force plate, TrackMan and motion-capture systems must record the golfer at the studio. Remote coaching remains useful, but it is a different service with different evidence.
Choose studio 3D analysis when:
You want synchronised body, ground, club and ball measurement, or a technical question has resisted simpler observation and coaching.

Frequently asked questions
3D Golf Biomechanical Analysis
What does a 3D golf biomechanical analysis measure?
The assessment can compare TrackMan club and ball data, SwingCatalyst pressure and three-dimensional ground reaction force data, and full-body movement data. The systems are interpreted together to clarify how movement and force use relate to club delivery and ball flight.
Will every assessment use every system?
Not necessarily. The technology is selected according to the golfer's question and the information needed. The purpose is to answer the problem clearly, not to collect every available number.
Can the same 3D assessment be completed online?
No. The combined 3D assessment requires the studio equipment and is completed in person near Bournemouth. Online coaching can use clear video and any data the golfer already has, but it is a separate service and is not presented as equivalent to studio capture.
Is this a medical or injury assessment?
No. This is a golf coaching and performance service, not a medical diagnosis or treatment. Golfers with pain, injury or clinical restrictions should seek advice from an appropriately qualified healthcare professional and share any relevant guidance before participating.
How long should I book for an initial assessment?
A 90-minute session is normally the best starting point for a new golfer. If the intended scope is unusually broad, contact Chris before booking so the appropriate session length can be agreed.
Where can I see current prices and availability?
The live booking calendar shows the session lengths currently offered, their prices and all available dates and times.
