My wife, a dub and I are all certified and I’m starting 2 more kids on certification this winter. I’m looking for an air integrated wrist computer that can monitor multiple wireless units (preferably at least 4). Anybody have any favorites or recommendations?
If the point is to monitor the other divers’ cylinder pressure, I believe there’s only the Garmin transmitters that have sufficient range for that (and even then, it’s tricky). Most transmitters will top out around 1-2m range, whereas the Garmin transmitters can have a range up to 10m (in ideal, line-of-sight conditions). I believe you can have up to 4-5 transmitters paired with a computer.
I would recommend teaching everyone good habits and have them monitoring their own pressure, but that’s just me.
