Initial Setup The gFlight V2 works by using micro-sensor technology and laser beams so both units can talk to one another, making the gFlight V2 a completely wireless device Distances of up to 19-feet can be used with full battery power...
Proper Jump Alignment Line up your pinky toes with the sensors. You may want to take a small hop before you take your first jump. This will test to make sure the sensors are lined up properly and the metrics are appearing on the display unit The gFlight’s sensors need to be free of all obstructions...
Proper Landing Alignment Landings need to be consistent. If you land outside of the sensors, the jump will not register. We have found that a couple of practice jumps or adding a visual landing marker can help limit the error. Optimal Landing Not Optimal Landing...

gFlight Performance Metrics The gFlight will provide you with 4 metrics: IN = Jump Height in Inches CM = Jump Height in Centimeters GCT = Ground Contact Time (ms) RSI = Reactive Strength Index Each metric will be explained in depth on the following pages.
Jump Height The gFlight measures the time the athlete is in air. Time in air is measured in milliseconds (ms). It is measured from the time the athletes foot leaves the sensor’s beam to when it comes back into contact with the sensor’s beam (beam disruption).
Ground Contact Time (GCT) GCT is the length of time one’s feet are on the ground preceding the jump. This metric is typically only useful for continuous movements (i.e depth jumps, hops, or bounds). GCT will not be useful for a single jump. Drop Jump...
Reactive Strength Index (RSI) RSI is derived from ground contact time (GCT) and jump height. It is a composite score used to measure the level of “reactive strength”. Typically a higher RSI will yield a more explosive athlete It was developed at the Australian Institute of Sport and more information can be easily found on the web (link below).
gFlight Best Practices - Review The gFlight is best used indoors (no sun interference from outside) The gFlight needs to be lined up properly (sensors facing each other) The gFlight metrics will be best if landings and takeoffs are controlled. The gFlight needs 6 AAA batteries, 3 in each unit to function The gFlight’s sensors need to be free of all obstructions...

Athlete Testing & Tracking Force-Velocity Profile Testing- using the JB Morin Force-Velocity profile generator (or other FVP generator) you can input jump height into the data sheet, along with other anthropometric measurements the generator will tell you if your athlete is force, or velocity deficient to help the coach build a better, more individualized program Percent Drop-Offs (Fatigability)- percent drop-offs in jump height can be assessed using the gFlight, first obtain a baseline jump height for the day,...

Athlete Testing & Tracking Power Test- this test is used to determine an athlete’s ability to produce and maintain power, this can be done via a simple power maintenance calculation Have the athlete jump 15 consecutive times, record each jump with the gFlight app. Take the average of the first 5 jumps (J1) and the average of the last 5 jumps (J2) Power Maintained (PM %) = J2 / J1 This percentage represents the athlete’s ability to maintain power overtime...
Third Party Testing - Force Plate The gFlight has proven time and time again to be a valid and reliable product. When compared to state-of-the-art force plates the average difference is 1.03 cm Click here to see the study...
Page 22
Third Party Testing - Reliability The gFlight has been compared to the industry standard of force plates to validate the accuracy and reliability of jump height. gFlight was on average less than a 1 cm difference in jump height over the course of 200 jumps over ten days.
If you are still having trouble connecting to the app, check to make sure that your phone’s bluetooth is turned on and is within range If problems persist, please contact support@exsurgo.zendesk.com...
