deco

Looking for an O2 ready deco setup with 1st and 2nd stage. Preferably Hollis but I'll take what I can get. Let me know!

Hello, I am a recreational diver with an AOW license and I use a Garmin Descent 3. I can't understand the difference between using a medium conservatism profile, going beyond the NDL limits but ascending slowly, following the computer's instructions—in essence, the decompression happens during...

Shearwater peregrine computer. You can use up to 3 nitrox mixes per dive of up to 100%. deco ready but great for even the most advanced recreational dives. It has not been used and has all the goods (case, charger, band, whatever comes with it). Wanting to sell this so i can get a trimix...

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...

Searched a bit but couldn't find the exact answer in the existing topics, so here comes my question: I have four 12 liter 232 bar steel tanks for my SM and Twinset dives, which I normally do in cold waters of Stockholm, Sweden. Now I'm looking to buy 1 or 2 aluminum tanks to use as stage /...

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...

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. If beggars can be choosers, I'd like something environmentally sealed and diaphragm (or Poseidon haha). Something like DGX, Dive Rite, ScubaPro, etc. It's fine...

2 Dive Rite O2/Deco regs. Both worked flawlessly when last used. HOWEVER, I RECOMMEND HAVING ANY LIFE SUPPORT EQUIPMENT EXAMINED/SERVICED BY A QUALIFIED TECHNICIAN BEFORE USE. First reg: RG5400 as pictured. Only used on 100% and 50% O2. This reg has less than 15 dives on it. Last dove it a year...

Due to an injury, my tech days are postponed for quite a while so I would rather turn these into cash. I am motivated to sell. Located in Broward FL and prefer local pick-up. All tanks have current Hydro and are DIN LP 85 Doubles Matching Pair HYDRO 9/18 $425 LP 108s Hydros 2/19 $140 each...

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?

Hi all For a deco cylinder on the left side. What are peoples thoughts about using a regulator with a standard (right) hose inlet vs a left hose inlet (shorter hose and not going around the neck)?

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...

Want to buy a dive rite reg for deco. Nothing special, preferably o2 cleaned and unbalanced first stage. Located in cave country.

In February I went to Protec and completed both Sidemount and Intro to Cave, but before I return next January for Full Cave I would like to get through AN/DP. Does anyone here have recommendations for a solid instructor here in Washington State who knows sidemount and can teach at a tech level...

Has anyone come across the actual algorithm that can be used in MS Excel?

Hi all For deco dives, do you 1. Have one deco/tech computer then a gauge/timer and prewritten dive plan? 2. Use two deco/tech computers If option 1: Do you use the prewritten plan or the computer, as your primary means of following a decompression profile? Do you have the written plan on a...

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...

Hey everyone. I normally dive solo out here in pompano but I would like to do some longer dives on some of these wrecks and need to find a buddy. Doubles with 1 or 2 deco bottles depending on the dive. It's very hard to find someone who is deco certified down here for some reason... I'm a...

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.
