lvi-57 rebreather tryouts

marwan, I would definately take heed of kiwi-diver's advice. Keep in mind the Soviets had different standards for the safe operational use of pure O2 than almost anyone else. If I am not mistaken, the US Navy had a 10 meter limit on 100% O2 for some time then changed it to 6 meters for saftey's sake. These limits also vary from individual to individual & are always under study & subject to revision. You can download the latest Navy dive manual, I believe someone posted a link here. You can search for it. If I am not mistaken, it will show some recent changes in the depth limits of pure O2, but it is still no where near 20 meters. It will also provide very good reasons to adhere to the limits. The Soviet's acceptable loss was quite different than any western country. Hope this helps.

i like the term acceptable loss - sounds so nice and clean, however keep in mind the soviets where not talking about the loss of equipment but loss of diver.

in any case the survival time of a Naval Spetsnaz was messured more in minutes than in days

AFAIK, this unit is not even a dive-able unit - it's for mine rescue / NBC / hazmat etc I do believe. Doubt you'd be able to take it ti the bath let alone to 20M; well, definitely not back anyway. No Spg - worse WOB than Kiwi_divers AKA-60, no superoxide scrubber usual on these sorts of units. About the only thing this unit has in common with a diving unit is the case, looks like a modified IDA64 case.

Greetings

I have seen this rig for sale on EBAY. It is a kind of Ox Rebreather - Russian made. The internal components look very much like an IDA type of rig.
I have an Russian IDA 64 - which is very nice Ox rig and works very well at shallow depths (under 30 fsw). The US Navy Ox tables do allow deeper dives and what are referred to as "excursions" - but they are for military purposes only.

Some of the Russian Ox rigs have some potentially dangerous design spects built into them. If you are not aware of these, you can get into serious trouble and not even be aware of how it can occur.
I would highly suggest you speak with Dave Sutton about this rig BEFORE you actually dive it. He has spent a lot time studying Russian Ox rigs and may be able to give you some information about this rig and whether it is safe to use.

Dave is a member of Rebreather World and can be contacted through this website.

Hope this helps.

It's a fire apparatus. Uses normal scrubber stuff.

Easially modifiable to be an 02 rig.

'Barely' modifiable to be a mCCR. Not worth the effort.

Deathtrap from a WOB standpoint.
