Three Variables. Complete Jump Profile.

01 — Jump Height
in / cm

Displayed instantly on the device and synced to EPS for longitudinal athlete tracking across sessions.

02 — Ground Contact Time
GCT

Time spent in contact with the ground during takeoff — a key indicator of explosive power and plyometric efficiency.

03 — Reactive Strength Index
RSI

Jump height divided by ground contact time — one of the most powerful single metrics for neuromuscular readiness.

Built for the Field. Not the Lab.

Solar-Shielded Sensor

Eliminates ambient light interference so you get reliable jump reads outdoors — on fields, tracks, and open courts.

Up to 10-Foot Sensor Range

Wider beam distance enables multi-athlete configurations without repositioning the unit between tests.

Instant On-Device Display

Jump height, GCT, and RSI appear on screen immediately after each rep — no phone required at the moment of testing.

Bluetooth to EPS App

Syncs wirelessly to iOS and Android for athlete profiles, session history, trend analysis, and program integration.

Multi-Athlete Testing

Rotate athletes through quickly in team environments — consistent, objective readings every single rep.

Your gFlight V2 + EPS = Complete Picture

EPS stores every session and builds a longitudinal record of each athlete — so you can track response to training, catch readiness dips, and program with confidence.
