How a race morning actually runs
A packed finish is a reader problem. Chip the field, stand up the line, and the last runner still gets a time — checked against backups and posted live.
Chip the field
Issue bibs and chips. Import the start list. Passive RFID — no battery on the runner. The antenna powers each chip as they cross.
Stand up the finish
Jaguar G4, antennas, jClock, PhotoVision. One or two people. Recording before the first wave hits the line.
Backup reads, live results
Times recorded, checked against backups, matched to registration, and posted to live results. You score the race in the workflow you already run.

The finish kit
Built for companies that time for a living
The Jaguar G4 is a 4th-generation RFID decoder — 300 reads per second — in a sealed case. The same system behind 18,000+ events a year, trusted by 500+ timing companies worldwide.
300 reads per second
Sealed field case
Trusted by 500+ timing companies
IP-67 with the cover closed. Rated −30 °F to 140 °F. Designed and manufactured in the United States.
Chip, photo, clock, backup
You're not selling a stopwatch. You're selling a finish the race director can defend — and an experience participants talk about after.
Chip timing
Jaguar G4 reads 300 chips per second — 4th-generation RFID, times to the thousandth. Built to capture a packed chute, not just a trickle of finishers.
Photo finish
PhotoVision cameras capture high-resolution, time-stamped finish images. Review close races frame-by-frame when a chip time needs visual proof.
Finish clocks
jClock puts sunlight-readable LED time on the chute — bib and finish time on the big display moments after they cross. Clients notice. Spectators stay.
Backup reads
Primary chip reads checked against backups in the same workflow. When a race director asks how you know, you have the file — not a stopwatch argument.

jClock on the finish
Race directors hire you for times. Spectators remember the clock. jClock is large-format, sunlight-readable LED time — 10+ hours of battery, Bluetooth or network control, designed and assembled in the United States.
