One quick thing

MAVTRAX sends the call to your catcher over Bluetooth — so they'll need a headset under the helmet. It works with any Bluetooth headset, even cheap $20 ones.

Connect the helmet

Power on the helmet headset until it says “pairing.”
On this iPhone open Settings → Bluetooth.
Tap the headset under Other Devices to pair it.
Come back and press TEST — you should hear “MavTrax connected.”
Turn the helmet volume all the way up.

Pairing lives in iOS, not the app. Once paired, every call plays to the helmet.
