FAQ
Questions about this package
How far can the wireless reach?
T-Link 3.0 runs 250mW with excellent range for typical autocross paddocks. If your site has line-of-sight obstructions (trailers, buildings), we can add an extended-range antenna kit to the quote.
What's the battery runtime on the wireless sensors?
USB-rechargeable IR emitters run 55–60 hours per charge. Plenty for a full weekend event. Bring a 5500 USB battery charger for overnight rotation.
Traveling between venues?
If you run multiple events per season at different sites, we can bundle extra sensor foam blocks, antenna extensions, and a display. Tell us what you travel with.
