    Unbalanced regulator for high O2 deco mixes

    I need to get an O2 clean regulator for deco BO mixes with high O2 that will be used in the 3-12 m | 10-40 ft range. Does it matter if the first is balanced given these depths? I am condemning Dive Rite FT1 (FT1 First Stage - Dive Rite) which is balanced and costs ~470$ vs Dive Rite O2 regulator...

    How does AluS080 11.1 ltr for deco/stage tanks sound?

    Best Digital Dive Planner

    While reading a recent thread on dive planning using tables vs computers I noticed a few divers throwing out digital app based dive planners or homemade smart sheets they use for basic deco dives to more complex multi gas deep dives. I’m hoping this will become the thread where everyone shares...

    Riding deco ceiling on ascent

    I recently had a look at a friend's Suunto D5 user manual and was very surprised to see this statement: NOTE: It is always recommended to keep close to the decompression ceiling when ascending. In fact, the depth -- labeled "Stop" on the main screen -- seems to be identically the ceiling value...

    Hello everyone, I'm looking for a bailout/deco reg set that will first see use on a pony bottle, then maybe on a stage cylinder later.

    Dive computer between several days?

    I just recieve my first dive computer. My question is do we turn the computer off between Days? For example I will be on a dive vacation for several dive in a row. Should I just leave my Cressi Leonardo in post dive mode, or turn it completely off at the end of the day?

    Problem trimming out with two deco tanks

    I have a upcoming Trimix course in September so I’m practicing diving with two deco tanks. Before this I used to carry either an AL80 or AL40 for deco, which I hardly notice through the whole dive. I like the idea m carrying both tanks on my left. However, I had some trouble with my trim with...

    GUE lost deco bottle procedure

    Hi, I would like to understand how the GUE procedure works when one team members has lost his deco bottle and it is time to perform deco. As I understand, teammates then share their deco bottle with the diver who lost his deco bottle, but I am not clear as to how this is done. Let's say you need...

    No deco time proximity.

    I am having a long time discussion with a buddy about the no deco time shown in a computer. How close can you get to the zero time while diving, without risking too much. Some opinions are to go up when you reach the 10 min mark, some consider the 5 minute mark.

    Where to put a stage bottle?

    Hello Ladies and Gents, Here is the question. Where do you guys and gals carry a stage when you also have 2 deco bottles. I generally don't carry bottles on the right side due to my canister light which comes with me on almost all dives unless absolutely no light would be required (40 ft...

    Simple Theory Question

    Let me apologize in advance if this has already been discussed ad nauseam in another post. Two divers diving at the same depth, let's say 100', diver 1 starts the dive with 80CF of gas, diver 2 starts with 120CF of gas. Both get back on the boat with 15CF of gas remaining. Seems to me that...
