I'm so honored to be the topic of this week's video! Thanks for your insight and advice Mark. Not to mention the cool points I just got with my fiance.

The added comfort of the updated omni-swivel was immediate and noticeable. While it does technically add another failure point, that risk is incredibly low. Look at any CCR diver and the number of failure points they have on their setup. Dr. Richard Harris has dove 243m/800ft on CCR. If that number of failure points is acceptable at those depths, an added swivel for recreational diving (especially with modern gear) is not an issue. The shop being discussed here seems to be overreacting.

I agree. Technically they're right, but the odds of a failure are so low that it really isn't worth obsessing about.

I see 110° adapters available online from many suppliers. Maybe a good option if you can't find a 120°

I use 90 elbows on my sidemount and twins rigs to give me the ideal hose routing and I personaly have never felt any need for a swivel. But unfortunately the only gen on mean time between failures for any of these things is anecdotal at best. I suspect the probability of failure per dive is very, very small, and we generally have some redundancy anyway. But does redundancy mean more failure points and is that therefore less safe........

Doesn't that depend on where the redundancy is?

#askmark I'll do my divemaster in a few month time and plan on trying some tec diving this year as well. My computer at this point is enough for recreational diving but certainly not enough for tec. Would you recommend buying a top end computer like a perdix if I want to go into tec or should I rather buy something in between if I only do entry level tec diving? greetings!

You won't regret investing in a Perdix, even if you only ever use it for recreational diving. For entry-level Tec you'll probably be surprised how much your dive computer can do. Most computers have enough settings to allow for deco diving and diving beyond 40m. If you do fancy an upgrade though, the Perdix is at the top of my list to recommend.

# Ask Mark, Mark you talk about maintenance of a swivel joint, I have an Atomic Aquatic regulator and I don’t think it has any screw adjustments for the swivel joint?

Now I see (Plastic) 360 swivel what is your opinion used it in "salt water" 03/37/24

I tend to stay away from plastic as much as possible because it usually hardens and breaks in cold water. And if plastic clips have moving parts, they wear much faster than metal clips and fail at some point.

#askmark Hi Mark, always informative content, keep going ! I am at the beginning of my recreational diving career and considering my first dive computer. I already own an Apple Watch Ultra: would you use it together with the needed Oraceanic+ subscription or would you suggest to look at other options, I like the Sheawater Peregrine, and it'd be even better if it had a compass. Note: at this stage no plan to go into tec-diving .

The Apple Watch is good for a recreational dive computer. You have access to all of the essential diving features on the app for free. the paid version unlocks a few extras but, it isn't essential. I do love Shearwater dive computers and the Peregrine is a smart computer. I'd try the Apple Watch first, see how you get on with that first as a dive computer before investing in another computer. If you don't get on with it then the Peregrine would be a great choice.

Hi Mark. Just stupid question here but I will ask you anyway. Trying to use an air integrated computer with a transmitter connected to my first but I'm not ready to say goodbye to my SPG just yet . Can I use both or you think it is an overkill ? also if my first only have one hpp can I use an adapter ? if so can you tell me wich one , thanks

#askmark Hi Mark I'm thinking about becoming a sidemount diver, so but BCDs could become quiet expensive, if you got a back-, sidemount and maybe a double tank BCD. So I thought about to choose a Hollis SMS 75 or something similar. But I wonder which BCD would recommend. Secoundly would you even recommend a BCD which is something like 2:1? Maybe I'm weird but I thought about a 2:1 because this way I would be able to get three tanks but smaller ones then one 15L. Thanks. Ben

I've dived the Hollis SMS 100 on singles and sidemount which is similar to the 75. It's an ok solution if you only intend to invest in a single BCD. Most sidemount divers invest in a dedicated sidemount BCD. It's hard to get a backmount BCD that does pure sidemount very well. It's better to use a school sidemount BCD for the course and then decide if you want to invest in a pure sidemount BCD. For diving single or twin cylinders with a sidemounted cylinder then a standard Backplate and Wing is your best choice

#Askmark Talking about failurepoints. I recently had a discussion with my buddies whether or not to have air integration. Their stand was about the additional failurepoint. I am thinking there is just little difference between an AI transmitter compared to a dummy plug in the first stage. Not talking about a short hose that would indeed add additional o-rings. Do I miss something important here?

@ScubaDiverMagazine

Жыл бұрын

I'm fine with transmitters. They're an acceptable failure point in my books and the benefits outweigh the costs. I always fit one to my regs when I go diving and I've never had a failure on one.

#askmark Hi Mark - i do about 4 trips per year for warm water, recreational diving. Is there a problem with disassembling my hoses and regulators for travel and storage? I protect the exposed hose ends from damage and debris with rubber caps. I also like the fact that all of my hoses hang straight with no tension when stored. I ask because I do not see anybody else following this practice. I look forward to your thoughts.

@ScubaDiverMagazine

The only problem is increased risk of contaminants and stripping threads. You sound like you know what you're doing and you're not going to strip threads by over-torquing. I pull my regs apart frequently and haven't seen any issues with additional wear or anything. Just keep dust and moisture out and you should be fine

Dont you do buddy checks when you get into the water anyway? What are the odds that both 0 rings begin to leak at the same time and go unnoticed?

Sorry Mark, swivels are poor design. 1st time, dive 15 of swivel, medium leak. Screw backed out. Tightened with tiny bit of threadlock. 2nd failure, 30 dives later, full O ring blow out at 90' with a tiny bit of deco. Barely able to complete, surface with 300 psi. 20 bar. Checked fitting evry dive. Swivel went in bin. Swivels are a bad idea imo.

"full O ring blow out at 90' with a tiny bit of deco. Barely able to complete, surface with 300 psi. 20 bar" I would be less concerned about the swivel and more concerned about going into deco without the ability to finish it on a single tank without going to empty.

#askmark different Steve here what about using quick disconnects on your second stages?

@ScubaDiverMagazine

Жыл бұрын

Quick disconnects are ok if they're required but, I'd always choose one with a locking mechanism to reduce the chance of accidental disconnection. Sometimes an inline shutoff valve can be more practical to prevent a freeflow. I only tend to see QDs on full face masks so you can disconnect the hose on the surface and breathe from the SAV. that way you don't leave your FFM dangling in the water or dragging on the floor.

They are captive so they aren't going to "go" anywhere. They might get leaky but nothing that would be more than a nuisance.
