What's the difference between UNO, DUO and G4?
Updated 20 October 2026
FYI, we only make G4 gates now, in either single or dual beam.
Functionally the only difference between G4 and UNO or DUO is the inclusion of SwiftAir.
SwiftAir has a different connection process in the SYNCRO app, which guides you through the process. Follow the in-app prompts and you should have no problem.
Also, you should note that SwiftAir must be enabled in settings in the Syncro App.
With the latest gate firmware, SwiftAir works across all drills.
