Main use cases in American football
Sprints
Time your Start-Finish drills and measure total time, speed, best time, time gap, and ranking. The American football packs are designed for this type of use.
Split times
Add one or more intermediate transmitters to analyze specific running sections. The current page and quick guide indicate that it is possible to obtain up to 2 split times with the setups presented.
Combine-style agility drills
Use MyFreelap preconfigured drills to time your combine drills.
Agility tests
Start your agility tests from the MyFreelap library of preconfigured drills, with detailed tutorials to get started faster.
Group training
Time multiple players with a setup designed for team training. The current page presents an advanced pack that can time up to 5 players in standard timing mode.
Useful components
FxChip BLE + FxBelt
Attach the FxChip BLE to the player’s shorts or to the FxBelt. Place it at waist level, centered in line with the navel and in a vertical position. Activate it by shaking it horizontally. Its stated battery life is approximately 100 h, its charging time approximately 5 h, and it automatically turns off after 30 minutes without transmitter detection.
Tx Pad Pro
Use the Tx Pad Pro as a ground start trigger. Place it on the start line, keep your finger in the start zone, then quickly remove your finger to instantly trigger the start of the timing.
Tx Pro Team
Use the Tx Pro Team as a start transmitter for certain drills. Clip it to a stake or tripod, place it on the start line, set it approximately at the same height as the player’s transponder, and point the arrow in the running direction. Start approximately 50 cm before the transmitter, always passing within 80 cm of it.
Tx Junior Pro
Use the Tx Junior Pro as a split or finish transmitter. Place it on the ground, at the edge of the track, less than 1.5 m from the player’s path, and 80 cm after the desired distance, except for flying starts. Then select the correct code : START / LAP / FINISH.
MyFreelap
Create your training session in MyFreelap from the home screen. Select a preconfigured drill with tutorial, or use Quick Timing to start with the basic features, then click Start to receive your data.
Mobile device
To ensure perfect data reception, place your mobile device between 10 m and 50 m maximum after the FINISH transmitter, approximately 1 meter above the ground. If you are using a Relay Coach BLE, place it 10 m after the FINISH transmitter, approximately 1 meter above the ground.
