    Drysuit and squeeze question

    True, because the pressure inside the hardhat dropped to 1 ATM because of the failure. The external pressure then forced the diver into the hardhat. The end result was kinda messy. I've even heard tales of divers exiting through the air hose. Nope. Cannot happen. The drysuit is not connected to...

    Drysuit and squeeze question

    Your breathing capacity would be maybe 30 % but not zero. This is widely experimentally proven in squeeze training/competitions in caving where people actually breathe (laborously) without being able to expand their chest. Enough to survive, enough to cause panic in the uninitiated.

    Drysuit and squeeze question

    So, it will be tight to the skin, but it will not crush you (because you are not compressible, as you said). The suit will be VERY tight, but it will only become a second skin.

    Cold water urticaria.

    A drysuit AND warm clothing beneath it. Gloves and woollen socks, too. Get a warm hood. Some of you skin (face) could get exposed though, so perhaps you want an "icehood" (search for one online, e.g. the H2 icehood).

    Drysuit and squeeze question

    In this video the backpressure valve of the helmet has failed (and the pump too). In this case the pressure inside the helmet is 1 ATM and outside maybe 6 ATM. And guess what happens. Now, your drysuit (helmet) will not have a hose connected to the surface unless you are a commercial diver.

    Drysuit and squeeze question

    As the ambient pressure increases (and hence the pressure inside the suit - they are equal because the suit is not a pressure vessel but made of flexible cloth) the air inside the suit gets compressed. This allows the suit fabric to come closer to your skin. You may wear some undergarments...

    Canister light routing

    I do ask you to think. If you do wear a drysuit, then the exhaust valve controlling you buoyancy is on your left hand. This means your depth gauge (which you constantly need to see) must be on your right arm. Hence, the light must be on the left.

    Diving at Iceland/Silfra

    I do not remember which company I relied on. Pick one though, that guarantees small teams. Please familiarize yourself with the drysuit. It is a beast to controll. Ten hours with it will make you "experience" so much better.

    Coolest/Most Unique "Finds" While Diving?

    If not a winner, then at least worth a honorable mention in the "weirdest thing affecting a diver on high seas". I mean, thats, ... epic!

    Yes! Those precious moments of life are worth cherishing! And even if the phone would no work, the pics on the SD-card (removable, hopefully), are intact. You do live in a happy place. ♥️ 😨

    Coolest/Most Unique "Finds" While Diving?

    I am a search and recovery diver. Hence, my list is a bit long. I could have picked one or two items only, but it is fun to share, so... I've found a few interesting things, indeed. I live in a city that was formed in the 13th century and it has a river flowing through it. On one of my dives I...

    Question Separate pool equipment for DMs/instructors?

    Four hours in a pool? Wow, that's epic! I've only seen 2 hours max. It wasn't a full time job, though.

    New diver, happy to be here!

    Welcome!

    Question Separate pool equipment for DMs/instructors?

    Doing business does incur some costs. Why neoprene in a pool? The water is warm. Soaking is against the ocean salt. Please refactor it in course fees.

    Finally did my first SCUBA experience and enjoyed it despite my disability

    Deep diving is a required part - at least for PADI and CMAS. CMAS International Diver Training Standards and Procedures Manual, for example, sets a 25m or 82ft dive as a requirement, but it does not specify how much time you need to spend below 60 ft. PADI has its own requirements. And then we...

    Finally did my first SCUBA experience and enjoyed it despite my disability

    The 90 feet limit for advanced open water divers is a maximum safe depth. I don't think it's a compulsory depth :) The "experience a deep dive to 90ft" AOWD-thing is for people with no pressure related limitations. For you 60 feet is probably "deep" because of the imminent danger that you pump...
