PADI Open Water - Equipment I Complete Assignment With Questions Fully Solved.

suitability, fit, and comfort - correct answer What are the three most important considerations in choosing scuba equipment? Suitability means that the equipment is appropriate for you and the dive. - correct answer What does "suitability" mean? Fit means the equipment is sized and adjusted for you. - correct answer What does "fit" mean? Comfort means you can wear the item for an hour or more without a significant ant distraction due to its feel or configuration. - correct answer What does "comfort" mean? cost and features, serviceability, color and style, and accessories - correct answer What are four secondary considerations when choosing scuba equipment? 1. Inspect your equipment for proper operation, wear, and damage before each use. 2. Rinse everything thoroughly in clean, fresh water after use in salt water, chlorinated, or fresh water with silt or dirt. When it's dry, store in a cool, dry place. 3. Avoid leaving your kit exposed to direct sunlight for extended periods, and cover it between dives. 4. Have items that require periodic professional inspection serviced regularly. 5. Follow any maintenance requirements specified by the manufacturer. - correct answer Different pieces of scuba gear have specific care requirements, but all items have five steps in common. What are these five steps? d. comfort - correct answer The three most important considerations in choosing scuba equipment are suitability, fit, and __________. a. cost and features b. color and style c. manufacturer d. comfort a. true - correct answer Getting the service my gear needs may be a consideration when choosing equipment. a. true b. false a. inspect - correct answer Before each use, I should __________ my equipment. a. inspect b. wash c. warm d. dry You need a mask to see clearly underwater. - correct answer Why do I need a mask? Your eyes must be in air to focus properly, but your mask creates an air space that you have to equalize. This is why your mask must enclose your nose — so you can blow air into it. - correct answer Why does my mask need to enclose my nose? 1. Low profile masks that sits close to your face gives you a wider field of view and requires less air for clearing of water and equalizing. 2. Wide vision field. 3. Silicone color can either reduce glare or offer a more open water feel. 4. Frame color. - correct answer What are four desirable features to consider when choosing a mask? To check the fit, place the mask gently against your face and inhale slightly through your nose. It should stay in place with light suction without pushing or twisting to make it seal. - correct answer How do I check the fit? You may need to scrub the interior of the glass with a mask cleaner to remove chemicals that increase fogging. Other than that, your main preparation is to adjust the strap. - correct answer How do I prepare a new mask for diving? b. my eyes must be in air to focus - correct answer I need a mask because... a. I will inhale water without it b. my eyes must be in air to focus a. equalize the mask - correct answer My mask encloses my nose so I can... a. equalize the mask b. suck the mask into place b. false - correct answer From among masks that fit me, I should choose a mask that fits as far away from my face as possible. a. true b. false c. above my ears, over the crown of my head - correct answer I want to adjust my mask so the strap rests... a. below my ears, above the neck b. over my ears, below the crown of my head c. above my ears, over the crown of my head 1. A flexible lower portion to allow the snorkel mouthpiece to drop out of the way when not in use. 2. A self-drain valve to make it easier to blow water out of the snorkel. 3. A splash guard to reduce the amount of water that can splash in during use. 4. A color that you can math to your other gear, or a bright color that is easy to see. - correct answer What are four features to consider when choosing a snorkel? Your snorkel goes on the left side of the mask strap using its clip, slot, or keeper. With the mouthpiece in, the tip is over the crown of your head. - correct answer How do I prepare my snorkel for diving? a. true - correct answer Snorkels are standard equipment for scuba diving because they allow me to breathe with my face in the water, or in rough conditions, without wasting my scuba air, especially when I have little scuba air remaining. a. true b. false a. true - correct answer Some scuba divers prefer a snorkel with a flexible lower portion so it drops out of the way when not in use. a. true b. false b. over the crown of my head - correct answer When my snorkel is in my mouth, the tip should be... a. above my forehead b. over the crown of my head c. at the base of my skull Fins provide a large surface area for your powerful leg muscles to push against so you move efficiently through water. - correct answer Why do I need fins? Adjustable strap fins are open at the heel and straps hold them in place. They are usually worn with wet suit boots, which provide warmth and foot protection when walking on shore or a boat deck. Full-foot fins enclose the heel and fit like snug shoes or slippers. They are usually worn with bare feet or thin fin socks, so they're for warm water use. Full-foot fins have different blade sizes — some are suited to scuba, but others are best for snorkeling only. - correct answer What are the two basic fin styles? Describe each. Primary considerations in choosing fins are fit and blade size. Optional features and considerations include material, split fins, vents, quick-release straps, and spring straps. - correct answer What features should I consider when choosing fins? a. true - correct answer Fins provide a large surface area so my legs can push against the water effectively. a. true b. false d. adjustable and full-foot - correct answer The two basic fin styles are __________ fins. a. large blade and small blade b. freshwater and marine c. vented and split d. adjustable and full-foot a. blade size - correct answer My primary considerations when choosing fins are fit and... a. blade size b. material c. splits d. vents a. true - correct answer To prepare adjustable fins, I should adjust the straps wearing my wet suit boots. a. true b. false 1. BCD (Buoyancy Control Device) — holds your kit together and allows you to adjust buoyancy throughout the dive. 2. Regulator — delivers breathing air at the surrounding pressure when you inhale and directs exhaled air into the water. 3. Cylinder — holds the high-pressure breathing air supplied by your regulator during the dive. 4. Weight system — holds lead weight to counteract the positive buoyancy of your body and some of your equipment, with a mechanism for dropping some or all the weight in an emergency. - correct answer What four equipment systems combine to make my scuba kit (scuba unit), and what is the purpose of each? Consider choosing the components of your scuba kit as an integrated package to assure that it best meets your preferences. - correct answer What should I consider when choosing my scuba kit? 1. Inflatable bladder — this is a very durable bag that you inflate or deflate to change your buoyancy. 2. Cylinder band and harness/jacket — the bladder integrates with an adjustable harness that holds the cylinder on your back. 3. LPI (low-pressure inflator) mechanism — usually at the end of a large-diameter hose, the LPI inflates the bladder with air from your cylinder, via the regulator, when you press a button. Another button allows you to deflate the bladder, or inflate it orally
