2. Your exhale gas goes directly in to the scrubber, so if you use the sofnolime option, the absorbent will be soaked if you get water in the loop through the mouthpiece.

As a diver and instructor on the Sentinel, I can tell you that water ingress into the scrubber does not seem to be any more of a concern than on OTS counter lungs. The way the unit is designed, it is very simple to flush water through the system. Additionally, the insulation of the canister is some of the best on the market, which keeps the heat at a substantial level. I believe this contributes to the evaporation of water in the scrubber more quickly than a lot of units.
During our initial training, one of the students while doing drills, accidentally left his dsv open with the loop out of his mouth at about 20 meters. It floated above his head for 10 or 15 seconds. We were all very anxious after the dive to inspect his scrubber and see how much water was in the bottom on it. To our surprise, there was almost none. A combination of forcing water down through the scrubber and out the OPV in the bottom of the scrubber as well as the heat of the scrubber completely removed the water. It was actually quite amazing.
I like the unit a lot. The electronics are top notch. I really don't notice the size of the unit at all, especially in the water. I love the uncluttered chest area. It trims out almost perfectly for me right out of the box. The build quality is wonderful. The service from Delta P has been great. The breathing hoses are VERY long, but when you feel how easy the WOB is, you can put up with long hoses! The BOV is very good. The forced pre-dive checks may seem draconian to some, but I can already tell you from personal experience, that they absolutely force you to pay attention! Part of the thickness of the unit is because of the way the insulating space is around the canister. It is obviously by design, and it simply works. Good canister duration. Good WOB. Good durability. Good performance What else could you ask for? I know, I know, half the size, half the weight and half the price! Of course, with that, you would get half the performance! With many of the same performance features and some improvements from the Oroborous, it really is a VERY nice unit. Try it, you'll like it!
