For the last year I have been diving in Honduras in OC padi-land. Even though Im diving my evo I am on their profiles so I get 4 50-60 minute dives a day (god willing and the creek don't rise). Generaly I expect my scrubber to last through 4 tropical temp dives with the last two staying above the 20m range.

I also use 2442 psi bottles and expect to get 4 dives out of the O2 bottle and 3 from the dil. That means I either refill the dil bottle at lunch or take a spare bottle and change for the fourth dive. I carry a 40 with dil with an inlator hose attached as well.

There is no way in hell I would dive that way without a way to always know what's in all three bottles all through the dive. And since SPGs are known to be inaccurate at the bottom of their scales I bail out to OC if the O2 gets below 500 psi. Its a good drill and it avoids running the PO2 down while distracted by something else.

There are so many other failure points in an ECCR that are much more likely and have much worse consquenses than an spg leak, especially when compared to the benifit an spg gives.

I wouldn't want to drive a car without a working gas guage, certainly would'nt do it on life support equipment.
