Predator Firmware V59
V59 is recommended to all Predator users, as it addresses a flaw in the dive logging that can prevent dive logs from closing properly. This affected several of the previous versions, so all users are recommended to update.
For rebreather controller models, the 0.19 setpoint is no longer automatically promoted up to the low setpoint when wet.
In V56, a change was made to promote the 0.19 PPO2 setpoint up to the low setpoint (e.g. 0.7) whenever the wet contacts detected water. This change proved to be unpopular to the point that divers refused to update, so we have decided to remove this feature. The intent was to improve safety by preventing a diver from performing a surface swim with the setpoint at 0.19.
As a reminder, the 0.19 setpoint is only for maintenance and storage, and should never be selected when breathing on the loop, even if just pre-breathing out of the water.
As in all other versions, the 0.19 setpoint is automatically promoted to low setpoint when a dive begins.
For rebreather controller models, a “SetP = .19” warning is shown on the main screen when the PPO2 setpoint is 0.19.
This is to make it very obvious that the 0.19 setpoint is selected, as the 0.19 setpoint should never be used when breathing on the loop. See above.
Fixed a problem that could cause the dive log to be closed incorrectly, preventing that log from appearing on the Predator or in the downloaded logs.
Made changes to how non-volatile memory is updated during dive logging to improve long term reliability of the memory.
