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?
This is a number of years old, but has helpful answers to the same question – https://scubaboard.com/community/threads/computer-that-will-monitor-2-people.577876/ I am a Shearwater fan, but have not used the device in the scenario you described. I concur with the other commenter that teaching your kids monitoring discipline is a core scuba skill, along with agreeing on pressure callouts and reserve amounts during the pre-dive briefing.
