!WARNING:
Use of The Explorer manual
This user manual does not, nor is it intended to
contain any information needed to safely dive with
any type of SCUBA apparatus. It is designed as a
guide for the proper setup, operation, maintenance,
and field service of the Hollis Explorer only. It does
NOT take the place of a recognized training agency
instructor-led diver-training course or its associated
training manual(s) and materials. This user manual
is intended to be used only as a type specific ad-
dition to such training and materials, and as a user
reference. This manual cannot be used as a sub-
stitute guide for any other type of Self Contained
Underwater Breathing Apparatus (SCUBA).

!WARNING:
GENERAL SAFETY
No person should breathe from, or attempt to operate in any way, a Hollis Explorer rebreather, or any
component part thereof, without first completing an appropriate Hollis Certified user-training course.
Further, no Explorer diver should use a Hollis Explorer without direct Hollis instructor supervision until
they have mastered the proper set-up and operation of the Hollis Explorer rebreather. This includes
new Explorer divers as well as Explorer certified divers who have been away from diving for an extend-
ed period of time and would benefit from an instructor-led refresher course to regain skills and mastery
of the Hollis Explorer. Failure to do so can lead to serious injury or death.
!WARNING:
NITROX STATEMENT
The EXPLORER equipment is classified as being suitable for use with nitrogen-oxygen (Nitrox) breath-
ing gas mixtures containing up to 40% oxygen by volume without the need for special preparation,
cleaning, or component parts.
If Explorer equipment is subsequently used with equipment, or connected to an air supply system, that
is not rated for Oxygen Service, it can subsequently be used with Nitrox (32 - 40% O2) as long as the
equipment is maintained in accordance with the procedures and parts specified by Hollis.
The EXPLORER was designed for use with Nitrox (32 - 40% O2). DO NOT use gas mixtures with a
fraction of oxygen greater than 40% with your EXPLORER.
!WARNING:
CAUSTIC MATERIAL
The CO2absorbent used in the scrubber is caustic alkaline material. Take steps to protect yourself from
direct lung and skin contact. Furthermore, poor management of the breathing loop could lead to water
contact with the CO2absorbent, causing a “caustic cocktail” (very caustic liquid). This could lead to se-
vere chemical burns and if inhaled - possible drowning. Proper handling procedures, pre-dive checks,
dive techniques, and maintenance mitigates this risk.
GENERAL SAFETY
STATEMENTS + WARNINGS

!WARNING:
BATTERY WARNING
The Explorer relies on batteries to maintain a safe breathing gas content. Never dive the Explorer
without a sufficient charge on the rechargeable batteries. See "Batteries" PART 2 Section 1 for further
details.
!WARNING:
DESIGN AND TESTING
The Hollis Explorer has been designed and tested, both in materials and function to operate safely
and consistently under a wide range of diving environments. You must not alter, add, remove, or re-
shape any functional item of the Hollis Explorer. Additionally, NEVER substitute any part of the Hollis
Explorer with third-party items which have not been tested and approved by Hollis for use with the
Explorer.
This includes, but is not limited to, hoses, breathing assemblies, electronics, breathing gas delivery
assemblies and their constituent parts, sealing rings, valves and their constituent parts and sealing
surfaces, latches, buoyancy devices, inflation and deflation mechanisms and onboard alternate
breathing devices.
Altering, adding, removing, re-shaping or substituting any part of the Hollis Explorer with non-ap-
proved parts can adversely alter the breathing, gas delivery or CO2absorption characteristics of the
Hollis Explorer and may create a very unpredictable and dangerous breathing device, possibly lead-
ing to serious injury or death.
Non-approved alterations to functional parts of the Explorer will automatically void all factory war-
ranties, and no repairs or service work will be performed by any Hollis service professional until the
altered Explorer unit is brought back into factory specifications by a Hollis service professional at the
owner’s expense.
!WARNING:
COMPUTER / CONTROLLER-SPECIFIC WARNINGS
This computer is capable of calculating deco stop requirements. These calculations are predictions of
physiological decompression requirements. Calculations are for contingency use only. The Explorer
in this “sport” configuration is not intended for decompression use.

!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 (CO2poisoning), 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.

!WARNING:
COLD WATER
Diving rebreathers in frigid water requires special equipment, training, and preparation to prevent pos-
sible injury or death. Rebreathers present unique variables to cold water diving that are not a factor in
open circuit diving in the same temperatures. Cold water diving is beyond the scope of this manual.
There are many variables not listed here. It is essential and the responsibility of the diver to be aware
of all issues. The diver must know how to best prepare their equipment, and how to best prepare
themselves for the cold water environment. The diver must obtain further training beyond standard
Explorer training or Open Circuit Ice Diver certification alone.
Cold Water Issues Include The Following:
- Changes in temperature may lead to expansion and contraction of CO2absorbent material possibly
leading to channeling.
- Decreases in temperature effect the efficiency of the scrubber and greatly reduce the rated use
times.
- Sensors are sensitive to extreme temperatures. Storage of Oxygen Sensors below 32° F (0°) or
above 100° F (37.8° C) can damage or greatly shorten the life of the sensor.
- Mushroom valves may freeze open or closed if condensation is allowed to cool. Always perform the
Pre-Dive Sequence and pre-breathe the unit before entering the water and before any subsequent
dives. The diver should warm and visually inspect the mushroom valves between dives.
- Open circuit bailout must be rated and compatible with the environments dived in.
- Check the scrubber MSDS (Material Safety Data Sheet) for specific warnings about storage tem-
peratures. Scrubber material should not be allowed to freeze inside or outside of the rebreather.
