I just purchased a new regulator from a going out of business sale from a semi-local (meaning not to far away) dive shop. I currently dive a Zeagle Flathead XP, about to go doubles, so the new reg i've purchased is a Zeagle din Flathead VI. The reg was brand new and has never seen the water. I took it in the pool and it was great...easy breathing, no leaks....in 7 feet of water anyway. However there is one thing and basically i'm wondering if an environmentally sealed reg breathes different then a non-sealed, VI vs. XP. The new VI is the same when taking a slow breath, however when i take a deep fast breath it feels like something else opens up with a slight cracking sound. It does this dry or in the water....but as i said before no leaks or anything.....Is this normal with an environmentally sealed reg? My XP doesn't do anything like this....just wondering if i got a bad one.
