Suunto computers are notorious for locking the diver out. They also have crazy conservative settings.Wife and I sold our eon cores and got perdix AI’s after hers locked her out for no reason. And yes it was no reason, she had 4 hours of battery time left, locked her out for 48 hours because of a “low battery.” Sold them the next week.
Shearwater on the other hand…. Excellent well-earned reputation for no-nonsense operation.
