Full Swing KIT — 16 Data Points and What to Do With Them

The 16 data points explained

The Full Swing KIT uses 24GHz dual-mode Doppler radar enhanced with machine learning to capture a complete picture of both club delivery and ball flight. Every metric is unlocked out of the box — no subscriptions, no paywalls, no premium tiers.

Ball data (8 metrics)

Ball speed — the speed of the ball immediately after impact, measured in mph. This is the single biggest determinant of distance. Launch angle — the vertical angle at which the ball leaves the clubface. Spin rate — revolutions per minute of backspin. Spin axis — the tilt of the spin axis that produces draw or fade curvature. Carry distance and total distance — how far the ball flies and how far it rolls out. Apex height — the peak of the ball’s trajectory. Horizontal launch angle — the starting direction relative to the target line.

Club data (8 metrics)

Club speed — how fast the club head is moving at impact. Smash factor — ball speed divided by club speed, measuring energy transfer efficiency. Attack angle — whether the club is moving up or down at impact. Club path — the horizontal direction the club head is traveling through impact (in-to-out or out-to-in). Face angle — where the clubface points at impact relative to the target. Face to path — the difference between face angle and club path, which determines curvature. Side carry and side total — how far offline the ball finishes.

The relationships that matter

Sixteen numbers per shot can feel overwhelming. The key is understanding which metrics explain which other metrics. Here are the three relationships that unlock the most insight:

Face to path → shot shape

The KIT reports face to path directly, which is the single number that determines whether the ball curves left, right, or flies straight. Face angle controls roughly 75–85% of starting direction (higher percentage with driver, lower with wedges). The gap between face and path determines curvature magnitude. A consistent face-to-path number means a predictable shot shape — even if that shape is a fade or draw, consistency is what you can aim with.

Attack angle + dynamic loft → spin loft

The KIT doesn’t report dynamic loft directly, but attack angle combined with launch angle allows you to estimate it. Spin loft — the gap between dynamic loft and attack angle — is the primary driver of backspin rate. If your irons spin too much, the answer is almost always in spin loft: you’re either swinging too steep (negative attack angle too large) or presenting too much loft at impact.

Club speed × smash factor → ball speed

Ball speed equals club speed multiplied by smash factor. This decomposition tells you whether a distance problem is a speed problem (swing faster) or a strike problem (hit the center). A driver smash factor below 1.44 means you’re leaving significant distance on the table through off-center contact, regardless of how fast you swing.

The Full Swing app and data access

The Full Swing app is free, cloud-based, and available on iOS (no Android app as of early 2026). It stores every shot from every session with unlimited cloud storage, provides swing video replay, dispersion charts, club-by-club history, and trend tracking over time. The app also integrates with Apple Watch for real-time metrics on your wrist.

For simulation, the KIT is compatible with GSPro and E6 Connect, both of which log shot data in their own formats. The built-in 5.3” OLED display also shows metrics in real time without requiring a connected device — useful for quick range sessions where you don’t want to set up a phone.

Getting data out

The Full Swing app provides session history and shot-by-shot data that can be shared or exported. For CSV-format data, the GSPro integration path provides structured export. FlushLab’s Flush in a Flash AI Photo Scan also works with the KIT’s on-screen display — snap a photo of the OLED screen or the app’s shot result and FlushLab extracts the data automatically.

Where the KIT excels

The KIT’s standout strength is completeness without compromise. All 16 metrics are available immediately with no subscription. The OLED display means you can practice without a phone. The radar technology works equally well indoors and outdoors. And the accuracy, particularly for ball speed and carry distance, has been validated by independent reviewers against Foresight GCQuad-level devices.

The FS Combine feature, powered by Clippd’s AI, scores every shot to assess different aspects of your game — providing structured practice feedback that goes beyond raw numbers.

Where the KIT needs help

Independent testing has noted that spin rate consistency from the KIT’s radar can be less stable than camera-based systems like Foresight. Radar measures spin differently than photometric systems — it infers spin from the ball’s Doppler signature rather than directly observing rotation. For most golfers, the accuracy is more than sufficient, but if you’re doing precise wedge calibration where 200 rpm matters, be aware of this.

The app is iOS only — no Android support as of early 2026. For Android users, the OLED display and GSPro integration are the primary interfaces. The KIT also lacks the video-overlay integration that Rapsodo’s MLM2PRO does well — video and data are separate rather than combined in one view.
