Allright, full disclosure. What i've done is taken an ida72d2, replaced the dsv with one from an ida59, removed the O2 injection system, and replaced this with a normal second stage with the exhaust ports blocked. At this juncture, the only gas I have available is air. What I believe it is capable of doing is: 1. Giving me 4 breaths to each vent at the surface, 2.Giving me twenty breaths per vent at 132 feet. I have no means of monitoring the pO2 YET! The second I have my scrubber filled properly, I intend to test these beliefs. I will not be alone, and if a Mod1 class for converted ida72d2' s were offered, I would of course be the first in line.
Now that my dirty little secret is out, is anybody still willing to talk to me, or have we already reserved a space in the memorials? LOL
