Essential Accessory

How it Works
You'll notice the difference before your first session is over.
STEP 1 • Set Your Radius
Slide the Connector between your forearms. The super-soft memory foam settles in and you feel the connection immediately — the Radius Strap adds subtle awareness of your width. Keep that feeling.

STEP 2 • Maintain Width
Take the club back. Your arms and body move together — you can feel them working as one unit. The moment they try to separate, you know. There's no ambiguity. The Connector tells you before your have time to think about it.
As you move into the backswing, the strap stays with you — gentle elastic resistance keeping the arms and torso working together as one unit. The moment the radius collapses, you feel it.
STEP 3 • Rotate Through Impact
Rotate through. The connection holds. The centre rod shows your shaft lean at impact, the alignment rods confirm your structure stayed intact through the strike. That's what a connected swing feels like — and now your body has a reference point to repeat it.
Rotate through the ball with the radius intact. The strap holds the structure you set at address, letting your body lead and your arms follow. What you trained at setup is what arrives at the ball.
