Tx Track Pro
The versatile transmitter with a wide detection zone

Versatile transmitter
The Tx Track Pro is a versatile Freelap transmitter designed to act as a start, split or finish point depending on your setup.
Use it across several disciplines, including biking, alpine skiing, biathlon and speed skating, with a wide detection zone and fast setup in the field.
What is the Tx Track Pro used for ?
- start
- split
- finish
Choose the correct START, LAP or FINISH code according to your training scenario, then place the transmitter along the course.
Its extended detection zone makes it particularly suitable for disciplines where the athlete or rider cannot pass as close to the transmitter as in running.
The Tx Track Pro works with FxChip and FxChip BLE transponders, depending on the setup used.
Key strengths
Versatile
Use the same transmitter across several disciplines and for several roles in the setup : start, split or finish.
Wide detection zone
Benefit from a detection distance of approximately 3 m on each side, particularly useful for sports such as skiing, biking, biathlon or speed skating.
Easy to configure
Quickly select the START, LAP or FINISH code according to your needs.
Robust and rechargeable
Use a field-ready transmitter, designed to be resistant and rechargeable.
Multisport compatible
Integrate the Tx Track Pro into several configurations depending on your sport and level of practice.
Use according to your sport
01
Biking
Use the Tx Track Pro at the edge of the course to time a start, split or finish.
Place it less than 3 m from the rider’s or bike’s path, with the arrow perpendicular to the trajectory. For certain loop training setups, a single transmitter coded as FINISH may be enough.
