Air integration begins with the regulator
When tank pressure on the wrist is useful and what must remain in the gas scanA transmitter attaches to the first stage, so rental habits matter. A new diver who does not own regulators may be paying early for a feature that cannot be used on most trips.
01
Ownership
The regulator makes the feature available
Most rental operators will not reconfigure a rental first stage for a personal transmitter. Buyers planning to own regulators soon can still preserve the option.
- Now
- List how many dives use rental regulators.
- Later
- Confirm whether a non-integrated model can add the feature at all.
02
The scan
Tank pressure is one part of gas planning
Air integration can show consumption and remaining bottom time, but the diver still needs practiced checks, buddy communication and an understood backup pressure path.
- Transmitter
- Check compatible models, pairing and battery.
- Backup
- Follow training and team standards for an SPG or second pressure source.
03
The system
Network features require matching equipment
Garmin messaging and team pressure monitoring require compatible computers and T2 transceivers within stated ranges. A feature has no team value when the team does not share it.
- Buddy
- Price every required transmitter, not only the watch.
- Practice
- Rehearse alerts and lost-signal behavior before a trip.
