    Sorb-how much bouncing around in car is bad for packed scrubbers?

    My anecdote: The Prism 2 scrubber is annoying to pack and doesn't have a spring to compensate for settling, but its soft mesh sides do allow you to squeeze it and feel how tight the packing is, unlike some other scrubbers. I have often experienced carefully packing it tight, taking it on a very...

    Where to dive in November?

    Seeing as you're in NY, for something close to home you can actually still dive the St. Lawrence with decent comfort in November, the water stays relatively warm compared to local ocean diving through the Fall.

    How long can you store scrubber in the original canister?

    Does sofnolime break down or lose potency over time at all? If so, how? Is there a reason they put an expiration date on it? Is there science behind it? I've been considering whether to trash or dive an untapped keg of just recently expired sorb. Seems like it should be fine, but nobody wants...

    Came here expecting this thread to be an argument about when and if it's appropriate for children to do deco, lol.

    Tips on starting diving doubles

    My biggest tip for starting to dive doubles: go dive them A LOT. Lots and lots of shallow easy dives. Practice, make adjustments, take notes, do more dives, repeat. If you're diving a drysuit or thick wetsuit, you want steel not aluminum doubles.

    CCR training question

    What unit? Doesn't strike me as the worst thing, but you'll need some extra practice and training when the different unit arrives. That's alright because you should be doing LOTS of easy practice dives after your course anyway. You'll want to drill any procedures that are different, maybe do...

    Question Is there a high pressure version of LP50's?

    Don't overfill aluminum tanks! Well, maybe by like 10%, but you cannot safely "cave fill" aluminum like you can steels.

    Helium drysuit bouyancy

    No noticeable difference in buoyancy. It's a little bit colder and costs a few extra bucks. I do it on mild trimix dives when I don't want to carry a separate suit inflation bottle.

    Booty Recommendation??

    - Go to dive shops and try them on. - You can wear neoprene or other socks with your boots, might help - I like to use the thickest sturdiest neoprene boot I can get, I've had cold feet in cold water but never overheating feet in warm water. - You might look into sailing dinghy boots, similar...

    Half-packing sorb -- Possible, or deadly?

    I hate to be that guy on the internet attacking the premise without answering the question, but what's the issue with storing one packed scrubber for use over a couple of short dives? Why would it be so "impractical" to leave it sealed in the unit or a labeled drybag?

    Mask on forehead=panic. Where did this mask signal originate?

    Sometimes I pull my mask up on my forehead. It's a perfectly reasonable place to put it, sometimes. I don't put it up there when it could get easily knocked off and lost, eg. surf entry/exit or floating in deep water. More often I pull it down around my neck, where it is much more secure, but...

    Best CCR in 2025-2030 Rebreather Markets

    Small companies generally make the best technical diving equipment. More innovative features, higher build quality, fewer corners cut to pinch a penny. Big companies are just as (if not more!) likely to end support for an unprofitable product as small companies are to die.

    Best CCR in 2025-2030 Rebreather Markets

    Are you looking for a unit to dive, and looking for a big company to trust for long term product support? If so what kind of diving do you want to do? Or looking to buy units for some agency or company with specific procurement rules? If so, again, what kind of diving do you want to do? Or...

    Which do you think is less dangerous at 160ft? Open-circuit air or CCR trimix?

    Rather than continue to rehash the deep air debate - at what depth does CCR become safer than OC Trimix?

    To STA or not to STA?

    Some wings need them, some don't. I use one with my Dive Rite EXP. My Apeks WTX-D30 doesn't require one, it has little tank stabilizers built in. This keeps the tank closer and feels more stable than the EXP with STA.

    When my dad was in Boy Scouts, he dived some helium mix with navy divers in a pool and he got sick after

    - It's possible (but unlikely) that there was low O2 or even some CO in the mix. - It's possible that he wasn't equalizing properly and experienced some alternobaric vertigo which can cause severe nausea, I've seen this first hand more than once. It could happen in a pool. - It's possible he...
