Regarding the resealing of sensors, I've come to understand that statement from a couple of other experienced Rebreather divers. Do you have any material information that can be thrown in the public domain that illustrates that the statement is accurate?
Can you clarify the second part of your statement? Is the bag being filled with dry nitrogen associated with the failure or were you just noting that you shouldn't fill the bag with nitrogen? And if not nitrogen, what do you fill it with?
I have had long discussions with manufacturers on the bag, with them explaining to me the importance of this apparently simple feature. Sounds silly, but little details all add up to make a product.
The plastic the bag is made from is not just any old polythene that it appears. Then on the gas fill inside the bag, it is nitrogen, but humidity has to be at the right level. The effect changes to this has on storage life is quite dramatic. Basically, rebreather manufacturers should not mess with the bag: they should arrange with the manufacturer to get the correct product in the first place - properly specified, properly tested.
