Frequently Asked Questions

How accurate is the Freelap Timing System?
The Freelap Stopwatch has an accuracy of 1/100th of a second. The Freelap Timing System provides measurements that are typically within a couple hundredths of a second compared to photocell timing systems.

Does the Freelap Stopwatch use more battery when used in automated timing mode?
Yes, the Stopwatch uses more battery current when used in automated timing mode. The battery will last about 1,000 hours in this mode. The Stopwatch will automatically return to power save mode after 75 minutes of non-use. The Stopwatch can also be changed to power save mode manually when the training session is complete.

What is the purpose of the Freelap Sprint Belt? Can the Stopwatch be worn on the wrist?
Yes, all the automated timing functions will work with the Stopwatch worn on the wrist. When timing short sprints, placing the Stopwatch in the Sprint Belt is recommended to ensure the Stopwatch passes each transmitter at equal position with respect to the athlete to ensure the best accuracy.

Can multiple TX Junior Transmitters be used to measure splits?
Yes, splits can be measured using multiple transmitters. For example, it is possible to divide an 80 meter fly-in/fly-out sprint into four 20 meter zones using five TX Junior Transmitters.

What is the minimum spacing between transmitters?
The stopwatch has a "safe time" of one second, meaning the stopwatch can not be triggered twice in less than one second. This means the transmitters must be spaced with sufficient distance so that the time required to run that distance is at least one second. High school athletes typically have a maximum velocity that is less than ten meters per second, in which case, the transmitters could be spaced as close as ten meters. Elite athletes with a maximum velocity greater than ten meters per second would require a longer minimum spacing.

What type of batteries does Freelap use?
The stopwatch uses a CR2032 and can be replaced at a watch repair shop. The TX Junior uses 2 AA batteries and are user replaceable. The TX Touch has a permanent battery (can not be replaced) that is rated for 15,000 starts.
