Discussion Exit bag or scuba mask

[CosmicVoid]

I know this question has been asked a million times, but after reading many threads on this topic I still haven't received a conclusive answer.
I've read the instructions on how to set up both of these methods, both of them have something that worries me.

An exit bag is very fragile. One wrong move and I can pull it off or damage it. However an exit bag sort of guarantees that it will maintain the inert environment as long as the constant flow of gas is ensured and since the bottom of the bag isn't sealed completely, all the gas will escape not allowing any oxygen in.

A scuba mask is much more robust, because it's fixated on the head and it won't be accidentally pulled off or damaged, which is why it's more appealing to me, as well as the aesthetic factor of a mask vs a bag. The issue that I have with a mask is that unlike a bag it relies on having a tight seal to the face so that water doesn't get in, and while it may be a water tight seal, does that mean it's also a gas tight seal? Does that depend on the mask? I've seen masks online where it says in the description that if water gets in it will be quickly removed through the exhaust valve at the bottom or something like that, does that mean there's a chance for water/gas to get in?

If anyone could clarify this I would really appreciate it, thanks.

Some people have succeeded with a mask, some with a bag, both work.

It's down to personal choice, you'll need to use the search function, it's all been answered before, many times.

Mostly bag, a mask needs a proff. regulator-ventil.

Hi. Scuba mask is much better and safer, than exit bag. I have a PDF-instruction that shows what you need to buy and how it works. It´s in German, so I need some time to translate it. But if you want I can upload it for you and you can see on the photos what you need and how it works.

There is an English version of your SCUBA Mask process on my blog. Cheers!

I wrote you a message, Robin.
With the cheap mask in the guide, it will not work due to shallow breathing, but to learn the principle, it's very good. The needed adapter to connect the G5/8" 1st stage of the diving mask with the W24 N2 tank valve, is availabe in Germany without any problems or questions.

Ich habe dir eine Nachricht geschrieben, Robin.
Mit der billigen Maske in der Anleitung wird es aufgrund flacher Atmung nicht funktionieren, aber das Prinzip zu lernen ist sehr gut. Der benötigte Adapter um die 1. Stufe der Tauchmaske mit der N2 Flasche zu verbinden, ist in Deutschland problemlos und ohne Rückfragen erhältlich.

Da hast du recht
