Can you explain suit squeeze
Have been told it’s just uncomfortable, then also told it’s dangerous
Cheers for the content 👍

I recently did my drysuit course and found the latex neck seal to be very tight and because it was a demo suit i wasn’t able to trim it. By the second dive i found that i started to have pain behind my eyes when bending over or looking to far up or down. dives ended with no major issues but i had blood shot eyes by the time i got home and puffy and sore eyes the next day which leads me to believe i was slowly strangling myself. lesson of the day, don’t dive with an overly tight neck seal

I had the same problem diving in Norway once. I didn't bother bringing my own drysuit so I used their drysuits. All of their drysuits were brand-new and their neck seals hadn't been stretched yet. I started to feel light-headed in the RIB so I called it and took it off. Latex neck seals need to be stretched before you use them and if you ever feel 'off' in any way, just call it then and there.

@@ScubaDiverMagazine yes i’ve learnt my lesson in that respect it was just lucky that 4 out of the 11 people group were either DM’s or instructors so if something were to happen at least there were plenty of eyes on everyone. I also had issues with my mask letting water in around my nose which ended in my sinus’s taking in a lot of water which i thought might have been the cause of the discomfort. safe to say the next i dive dry will hopefully be in my own suit which i can trim/stretch the seals to my own comfort level. I also quickly learnt the importance of adequate under garments. i was diving in an AVATAR suit with one of there undergarments and it was no where near enough for 12 celsius water temp.

thank you mark. You did a very good job of explaining the mechanics of how a dry suit works is simple terms. keep up the good job you are doing

#askmark If I understood this correctly, neoprene drysuits aren't nearly as likely to bruise you when they squeeze because the material doesn't create creases the same way a trilaminate or bilaminate would. This makes sense. My question though, is a neoprene drysuit as likely to experience a dangerous level of suit squeeze as a membrane drysuit? Could they be "crushed" inside the neoprene the same way as if in a membrane? Thanks so much for all your content.

Sort of... One of the main benefits is that neoprene drysuits tend to be more form-fitted and you need less insulation so, there is less air space inside the suit to be affected by the volume change. That being said, you will still experience a squeeze if you don't add gas as you descend. There is an argument that the neoprene is more stretchy so it would be a bit more forgiving, but you will always need to add gas to your drysuit to alleviate a squeeze and add insulation no matter what your drysuit is made from.

I'm new to drysuit so I'm still working out how much gas to run in my suit. I run the shoulder dump fully open (as you should, except maybe if you're actively using your suit for buoyancy because your wing was destroyed somehow). However the first thing that gave me trouble other than learning how to vent gas reliably was that if you're vacuum packed you really lose the ability to back kick because you really need the material to be able to move around your torso and legs. Also it makes reaching twinset valves significantly more difficult. The issue is that these things are not super obvious to a new drysuit diver until they go to actually perform these actions - which could be for safety reasons! I think the problem with suit squeeze is not so much the squeezing on your body but more that the fabric folds get squeezed together and against your body. The sheer gripping force of all that friction means the material doesn't have the stretch and flexibility you need to move freely. I've never felt like I couldn't reach my drysuit valve, so there's never been any panic about not being able to add gas.

#askmark Hi Mark, would you compare Fourth Element HALO A°R with Santi 400, 200 or flex 190 undersuit in terms of keeping you warm capabilities ? Thank you

#ASKMARK how does the Weezle Extreme Plus. Compare to say 4th Element Halo AR and / Santi Bz 200/400. Looking to see comparisons of bulk, buoyancy and warmth

#askmark What is the best way to bring your emotional support boltsnap with you while flying? Tucking it in a pocket seems rude ... checking it in baggage just mean.

@ScubaDiverMagazine 7 ай бұрын

My Emotional Support Boltsnap is usually clipped to my keys in my pocket and most airport security understand it's importance to me and don't separate us for very long.

#askmark hey Mark, how do you know your drysuite is to big? A lot of people explain when it's to small but when is it to big?

@ScubaDiverMagazine 7 ай бұрын

If there are too many folds where air can get trapped inside, then your suit is too large. You need to be careful of long legs and large boots that don't fit properly because your boots will pop off your feet and you can lose your fins. It's a bit of a gut feeling, membrane suits do need to be roomy so they don't restrict you but, they still need to be fairly snug to prevent trapped gas and your boots slipping off.

#askmark hi Mark, my eyes needed glasses, for reading I needed +3 and a cylinder +1, same both eyes. My cousin -6 and -5.5 and about to order lenses for the diving mask. Since underwater things look closer, how to calculate the lens strenght our this cases. Thanks for your very informative videos.

#askmark Recently I seem to have developed a possibility of getting nausea during dives. Happened twice now. Both times while underwater, increased a bit till the end of the dive, but not enough to actually throw up. I don't get sea sick ever on boats. Someone told me it may be caused by coffee, and I did drink coffee on both of these days, which I didn't do for earlier dives. Is this a usual thing? Any other food that makes you nauseous?

@ScubaDiverMagazine 7 ай бұрын

Coffee is acidic and may be the cause of your nausea. Mixing with your stomach acid and the horizontal position I sometimes get reflux after a coffee. Orange juice and other acidic drinks or foods are best avoided along with excessive food right before a dive. I've read that ginger can help as well as peppermint but, I'd skip the coffee before a dive as much as you can

If you do spew, keep regulator in mouth. Vomit will exit through exhaust valve. Make certain to touch your tongue to the top of your mouth as a shield and inhale cautiously. Reason to keep second in mouth; we usually take deep breath immediately after puking.

probably the coffee. Drink water, maybe have some bread pre-dive @@TheRedbaron11
