Why Choose the Sensor 4S Pro?
Ultra-Direct Pro Feel
The Pro version uses Tectanium 2 lines for a thinner, stronger, more direct connection to the kite. Riders who value instant feedback, precise steering, and clean response will feel the difference immediately.
Minimalist in the Hands
CORE keeps the Sensor concept clean and intuitive: no clutter, no overbuilt feel, just a refined control system with premium components and a precise, confidence-inspiring layout.
More Versatile Safety System
SFS+ single-frontline safety gives the Sensor 4S Pro a modern flag-out system designed for maximum safety and broader kite compatibility, including fixed-bridle and pulley-bridled kite designs.
Built for Demanding Riders
Big air, freestyle, freeride, wave, and foil riders all benefit from the Pro’s crisp response, durable construction, smooth trim system, and fast line untwist after rotations.
Key Features
Tectanium 2 Lines
The Sensor 4S Pro uses Tectanium 2 lines for a thinner, stronger, ultra-direct feel. They reduce stretch and sharpen control, giving performance riders a more connected response from kite to bar.
Carbon Long-Fiber Bar
A new long-fiber carbon-reinforced high-performance polymer bar increases stiffness, strength, and load resistance while keeping the bar light and responsive.
Click-In Service Inserts
Reworked click-in inserts in the bar center can be replaced without disassembling the bar, helping reduce wear and extend the service life of the control system.
FlexTrim Backline Tuning
Integrated into the floater, FlexTrim allows fast and precise backline fine-tuning directly at the bar without untying knots or overcomplicating setup changes.
SFS+ Single Frontline Safety
The SFS+ system flags the kite on one frontline for a clean safety release and is designed to work with CORE models as well as many other compatible kite platforms.
Auto Untwist
Below-the-bar Auto Untwist uses ceramic bearings to automatically untwist the front lines after rotations, keeping the system clean and helping riders stay focused on the session.
High V or Low V Line Split
The adjustable line split lets riders tune the bar for CORE’s preferred High V setup or switch to Low V for specific kite preferences, short-line riding, or broader compatibility.
Vario Line Lengths
The included Vario line setup allows 24m, 22m, 20m, and 18m configurations, making it easier to tune kite speed, power, and feel for different conditions.
Pro Version Advantages
More Direct Steering
The Pro’s Tectanium 2 lines are designed for lower stretch and higher precision, giving the kite a sharper, cleaner response during loops, jumps, transitions, and powered riding.
Sharper Feedback Under Load
For big air and freestyle riders, line stiffness matters. The Sensor 4S Pro gives more immediate feedback when edging, loading, sending the kite, or redirecting for landings.
Premium Build for Heavy Use
From the refined grip to the replaceable inserts, premium line set, ceramic-bearing untwist, and clean bar architecture, the 4S Pro is designed for riders who spend serious time on the water.
Optional Compact Bar
The Sensor 4S Pro is also available in a compact 45cm version for smaller kites, precise wave control, or riders who prefer a shorter bar throw and tighter steering feel.
