WARNING:
HYPERCAPNIA, HYPOXIA, & HYPEROXIA RISKS
This device is designed to maintain a safe breathing gas under sport diving conditions. But like all
machines it could fail. To mitigate risks, it is essential that a diver is trained and fully understands the
risks of hypercapnia (CO
2
poisoning), hypoxia (oxygen starvation), and hyperoxia (oxygen poisoning).
It is also critical to have adequate bailout gas for the planned depth.
Be aware that a well packed and well maintained Scrubber is key in achieving a life-support system.
The Canister Duration Meter (CDM) is not a substitute for good system maintenance and Pre-Dive
checks. Always use your training and discipline to ensure the sub-systems in the EXPLORER are oper-
ating correctly.
Critical components and potential failures are:
- The scrubber seal around the scrubber
- A poorly packed scrubber
- Used or out of date scrubber material
Proper training and education are your best insurance against an inconvenient situation becoming a
deadly one.

WARNING:
ALTITUDE
For the Explorer to accurately gauge altitude and the preceding dive depths, the Explorer must be
turned on prior to diving. Additionally, diving at high altitude requires special knowledge of the varia-
tions imposed upon divers, their activities, and their equipment by the decrease in atmospheric pres-
sures. Hollis recommends completion of a specialized Altitude training course by a recognized training
agency prior to diving in high altitude lakes or rivers.
