CNS oxygen toxicity is not considered likely at PO2 levels below 1.30 ATA. It is however related to
the diver's work level. Performing strenuous tasks could cause the symptoms of oxygen poisoning to
occur at PO2 levels lower than they normally would appear during casual recreational diving.
WARNING: The nitrox features of the INSIGHT are intended for use only by
recreational divers trained for nitrox diving by an instructor certified by a
recognized training agency to teach diving with nitrox.
Diving with enriched nitrogen-oxygen (nitrox) mixtures requires special knowledge of the variations
imposed upon divers, their activities, and their equipment by the increased percentage of oxygen.
Sherwood Scuba recommends completion of a specialized Nitrox training course by a recognized
training agency prior to diving with any enriched nitrogen-oxygen (nitrox) mixtures.
WARNING: In the event that you exceed the maximum limit of per dive
allowable oxygen exposure, it is recommended that you allow a surface
interval of at least 2 hours before reentering the water. If you exceed the
maximum limit of 24 hour period allowable oxygen exposure, you should allow
a surface interval of at least 24 hours before reentering the water.
