S*^t you not (pun intended), but was diving in turks last week and this was on my mind as I hadn't gone in literally days but was afraid to take a laxative for fear of having to go while on the boat to and from the dive site or god forbid, during the dive. By the fifth day, I gave in to ducolax...

Given the speeds required to sustain high altitude flight, I would think that At 10000' your soda explodes yet commercial flights are pressurized to about 8000' and soda cans are routinely opened without incident. Hmmm....

Not true. Okay, given a catastrophic yes. The FAA classifies three levels of decompression: https://www.faa.gov/documentLibrary/media/Advisory_Circular/AC_61-107B_CHG_1_FAA.pdf (3) Types of Decompression. (a) Explosive Decompression. A change in cabin pressure faster than the lungs can...

Love your videos in the LI sound where i sail but do NOT envy the divers cleaning my hull in Manhasset bay. Ick.

It's not the pressurization per se that is required on any particular flight, it's the the partial pressure of oxygen available. FAA requirements are : Sea Level to 12,500' - No oxygen required. 12,501' to 14,000' - Required by the required crew if over 30 minutes at this altitude. 14,001' to...

Not sure if it was covered above but as a pilot, I can say that the FAA specifies in the AIM 8-1-2-d: Decompression Sickness After Scuba Diving. A pilot or passenger who intends to fly after scuba diving should allow the body sufficient time to rid itself of excess nitrogen absorbed during...

Hey Craig, Is that 48 hours with the unit off after a full charge?

Anyone know the turn around time for a battery change? I'm past the 5 year mark and probably due but have trip coming up at the end of the month.

As a non tec diver, I just leave one gas on and go to EDIT GAS to change the % before each dive as needed.

There's a reason pilots rely on checklists.

You want to perform some kind of a half assed autopsy on a fish?

But what units does it display RMV in? :troll:

Lashed to my inflator hose.

Or skip the long hose and use medium size one (40”) while still having a primary donate setup?

:clapping:

A DC that can display your actual air consumption rate while you dive will immediately tell you if you’re breathing too fast. Then you can make a conscious effort to slow your breathing and physical exertion to some target rate. I find it invaluable.

Get a dive computer that displays your SAC rate.

Try using an air integrated dive computer that displays your SAC rate. Here’s how I find it helpful…. I know from experience my rmv is typically between 0.4 to 0.5 cf per min for warm water drift dives. I know I can get a full hour dive at about 65ft with an hp100 if I keep my breathing in...
