Sauron
The photocells that see every millisecond.
Sauron is Athlense's wireless photocell for sports timing. It detects the athlete's passage with millisecond precision and sends the data to the ecosystem — without a single cable.
Price per photocell. Split timing requires multiple units.
Millisecond precision
High-speed optical detection with 0.001 s resolution on every passage.
100% wireless
No cables between photocells — they talk to each other and to AthLink.
Rugged and portable
Built for the field: light to carry, tough enough for everyday use.
Time any discipline
Athletics, skiing, cycling, swimming, agility drills: place the photocells at the start, the splits and the finish and get the times you need.
Many photocells, one system
Add pairs of photocells to measure splits and segments. With AthLink, everything flows into the same phone in real time.
