Sportsbox AI Level 2

Specialist performance sessions
Technology provides information. Coaching turns that information into a useful change.
60 minutes · £80
A specialist session using HackMotion technology to help you understand how wrist movement influences the clubface, ball flight, attack angle and quality of strike.
HackMotion provides real-time feedback through 3D visualisation, audio and vibration. Depending on your swing, we can investigate slicing, hooking, inconsistent contact, clubface control or difficulty repeating a change.
The objective is not to chase numbers for their own sake. We use the technology to make an important part of your swing easier to see, understand and feel, then leave you with one practical focus for continued practice.
90 minutes · £100
A structured session built around the complete putting process—not just the stroke.
We can assess setup, aim, putter-face alignment, stroke technique, pace control, green reading and pre-shot routine. Depending on your needs, the session may include Blast Golf, HackMotion, video analysis, putting mirrors, the Visio Golf putting template, the Eyeline Stroke Meter, Putt A-Line and Stack Putting practice guidance.
We’ll establish a clear picture of your current technique, identify the area most likely to improve and leave you with a practical way to practise it.
Premium performance coaching
The GC3 Performance Session is for golfers who want a deeper look at their ball flight, club delivery and performance patterns. The three-camera system measures ball and club data, indoors or outdoors, so Mark can use the information to focus the conversation on what matters—not to bury you in numbers.

Clarify the shots, questions or performance pattern you want to explore.
Use GC3 data, video and conversation where they genuinely add clarity.
Agree a practical priority you can take to your next practice.
