Prism 2 User Manual
As you can see from the preceding checklist, it is broken down into 3 main setup sections:
“Prism 2 Component Inspection”, “Prism 2 Assembly Order” and “Prism 2 Operational
Checklist”. The fourth sub-section of the operational checklist, “ Immediate pre-dive checks
& system settings” are for final “systems go” verifications prior to entering the water. You can
use the 3 main sections individually as follows:
Prism 2 Component Inspection: This section of the checklist is used to help you verify that
all parts of a complete Prism 2 are present and visually undamaged prior to packing it for
transport. There is nothing worse than boarding a local dive boat or landing in a foreign country
just to find out that you left your DSV/BOV in your dive locker back home.
Prism 2 Assembly Order: This is the list you will normally use to “build your rebreather” from
component parts.
Prism 2 Operational checklist: This is the section where you will test all assembled
components of the rebreather to make sure they are functioning properly prior to entering the
water. You will complete these steps after assembly and between dives, or if a piece of the
functioning rebreather has been disassembled at any time. This is the most critical part of the
entire set up process, since a non-functional rebreather will always become evident at some
point as you go through the operational checks. Do not dive the rebreather if it has not passed
every step of this checklist.
Immediate pre-dive checks & system settings:
These are the final few checks done with the unit secured to your body before jumping in
the water. While most checks are verifications of previously checked items, it is absolutely
imperative that you check these again before entering the water.
