High-Frequency Sensing

1,666
samples per second.

While cameras guess at 30fps, our IMU sensors capture 1,666 data points every second. That's 55x more temporal resolution. The difference between seeing a blur and seeing the truth.

TEMPORAL RESOLUTION

Your downswing in numbers.

A full downswing takes ~250ms. Here's what each technology captures in that window:

THE MATH

The gap between segment peaks: 20–50ms.
Camera resolution: 33ms.

At 30fps, a camera might capture ONE frame during the critical timing window between segment peaks. Our IMU captures 33–83 data points in that same window. That's the difference between "it looked fast" and "your pelvis peaked 12ms before your thorax."

WHAT HIGH-FREQUENCY REVEALS

The micro-timing that separates scratch from bogey.

With 1666Hz resolution, we can detect timing differences of ±9ms. That's the precision needed to diagnose kinematic sequence problems.

Sequence Overlap Detection

Know exactly when segments overlap instead of sequencing properly. 10ms difference = visible in our data.

Peak Velocity Tracking

Pinpoint the exact millisecond each segment reaches maximum angular velocity. Miss the peak = miss the transfer.

Deceleration Patterns

See if segments decelerate before the next one accelerates — the hallmark of efficient energy transfer.

Tempo Consistency

Compare timing gaps across swings. A consistent kinematic sequence = a repeatable swing.
