Answer:
The maximum depth is determined by which mission pack is fitted: O2-CCR, SCR, Dual Mode or eCCR.
The recommended maximum operating depth is 100m.
Under BS EN 14143:2013, the maximum depth any product can be certified to is 100m. However, the tests audited by the Notified Body prove the product remains within the EU limits for performance even at 350m. The product is also certified to NORSOK U101 to a depth of 450m.
In reality, the maximum working depth is limited only by the bailout that can be carried by the diver, and it is for this reason that Open Safety advise 100m to be the effective depth limit for this rebreather. For deeper diving, the Incursion Extended Range rebreather is recommended.
