In this quote, Ashley Scott is going over the challenges of diving and the constraints that include it. She discusses having doubles for some of the devices, which could describe having backup gear in case something fails. Nevertheless, she likewise notes that there are particular hours in which diving is enabled and then a mandatory waiting period of 12 hours before diving again.
