Qualifying To Teach The PADI Peak Performance Buoyancy Specialty Diver Course All new or upgraded Teaching status PADI Assistant Instructors and Teaching status Underwater Instructors (or higher rating) are authorized to conduct Peak Performance Buoyancy Specialty courses when using this outline. Unlike other PADI Specialty Diver courses, Instructors using this outline need not attend a Specialty Instructor Training Course or apply directly to PADI to be certified as a PADI Peak Performance Buoyancy Specialty Instructor. Likewise, PADI Instructors using this outline need not show experience in diving instruction (have certified at least 25 divers) nor submit documentation of having at least 20 “buoyancy” dives. All other General Standards for Specialty Diver courses apply. Specialty Instructor Training Course attendance is, however, recommended and encouraged. These courses provide hands-on training, technique demonstrations, course marketing information, current PADI Standards information, and instructor-level open water training. Peak Performance Buoyancy iii COURSE STANDARDS AND OVERVIEW The purpose of the PADI Peak Performance Buoyancy Specialty course is to polish a diver’s buoyancy control beyond the Open Water Diver level. The goal of PADI Peak Performance Buoyancy training is to enhance the student diver diver’s buoyancy control abilities through knowledge development and practical skills practice. Prerequisites To qualify for the Peak Performance Buoyancy course, an individual must: 1. Be certified as a PADI Open Water Diver, Junior Open Water Diver or have a qualifying certification from another training organization. 2. Be 10 years of age or older. The Peak Performance Buoyancy Dive conducted during the PADI Adventures in Diving Program may be counted toward this specialty at the discretion of the instructor conducting the specialty course. Instructor Supervision The Peak Performance Buoyancy Specialty may be conducted by any Teaching status PADI Assistant Instructor (or PADI Instructor with a higher rating). Specialty student divers may be indirectly supervised by the instructor during open water training dives. The maximum student diver-to-Instructor ratio for open water training is eight students per instructor (8:1). Considerations for Open Water Training The Peak Performance Buoyancy Course includes two open water training dives which may be conducted in one day. Student divers are required to log specialty training dives in their log books. Training dives may be conducted at night for divers who have completed the Night Adventure Dive or the first dive of the PADI Night Diver specialty course, or have qualifying night diving experience.

Administration a. [Complete paperwork – Enrollment, Standard Safe Diving Practices Statement of Understanding, PADI Medical Statement, Liability Release and Assumption of Risk. The PADI Student Record File contains all of these forms. Using it makes completing course paperwork easy and convenient.] Peak Performance Buoyancy 5 B. Peak Performance Buoyancy fundamentals – buoyancy check Learning Objectives. By the end of this topic, you will be able to: • Assess personal buoyancy control skills using the PADI Buoyancy Assessment. • Use the PADI “Basic Weighting Guidelines” to estimate the amount of weight needed to begin a buoyancy check. • Identify three circumstances when you should conduct a buoyancy check prior to diving. • Outline the five steps to help you conduct a buoyancy check at the surface. 1. The PADI Buoyancy Assessment a. [Have students individually complete the PADI Buoyancy Assessment and identify specific areas in need of development or further refinement during the course. See Peak Performance Buoyancy booklet or photocopy the pages at the end of this outline.] 2. Estimating needed weight using the PADI “Basic Weighting Guidelines.” a. The best divers don’t overweight. If you want peak buoyancy control, neither should you. b. [Review PADI’s “Basic Weighting Guidelines” with the students – basic guidelines, conversion estimates for salt or fresh water, estimating weight change due to air consumption and the examples. See Peak Performance Buoyancy booklet or photocopy the pages at the end of this outline.] c. Have each student estimate the amount of weight he’ll need to complete the dives in the course. 3. Buoyancy check a. When to conduct a buoyancy check • Each time you switch dive equipment • Each time you change diving environments • If you haven’t been diving in a while b. Five easy steps to help you conduct a buoyancy check at the surface: • Wear all your equipment • Enter water too deep to stand in and deflate your BCD completely • Hang vertical and motionless in the water while holding a normal breath • Add or subtract a small amount of weight until you float at eye level while holding a normal breath Specialty Course Instructor Outline 6 c. • As a final test, exhale. You should sink slowly Air consumption and the buoyancy check • During a dive, your tank will become more buoyant because the air you breathe from it has weight. • Take this into consideration when conducting buoyancy checks at the beginning of a dive, when your tank is full. • Depending on the tank you use, you may need to weight yourself slightly heavy at the beginning of a dive, so you’ll be neutrally buoyant at the end. • Consider conducting a buoyancy check at the end of your dive as well. C. Peak Performance Buoyancy fundamentals – fine-tuning buoyancy underwater Learning Objectives. By the end of this topic, you will be able to: • Identify three primary instances when buoyancy adjustment is needed underwater. • Identify when to use a BCD for buoyancy adjustment. • Describe how to fine-tune buoyancy underwater when using a dry suit. • Describe how lung volume affects buoyancy and how to use breath control to fine-tune buoyancy underwater. 1. Buoyancy adjustment underwater a. When properly weighted, and wearing only a swimsuit or dive skin, you’ll rarely need to adjust the amount of air in your BCD for neutral buoyancy. b. There are three primary instances when buoyancy adjustment is needed underwater: • To compensate for buoyancy changes as you use air from your tank. As the dive continues, you’ll slowly become more buoyant. This requires you to dump air from your BCD (or dry suit). • To compensate for buoyancy changes due to compression of an exposure suit (wet suit or dry suit). As water pressure increases on the suit (descending), it compresses, making you less buoyant. This requires you to add air to your BCD (or dry suit). • To compensate for buoyancy changes during ascent. As water pressure decreases on the suit (ascending), the air used to compensate for loss of buoyancy during descent must now be neutralized. This requires you to dump air from your BCD (or dry suit) upon ascent. Peak Performance Buoyancy 7 2. When to use your BCD for buoyancy adjustment a. The BCD is used primarily for surface support. b. Use the BCD to adjust your buoyancy underwater when diving with a wet suit. Those with Peak Performance Buoyancy avoid using their BCD like an elevator or lift. Use the BCD to adjust to neutral buoyancy at each depth level when wearing a wet suit. Put air in when descending to remain neutral; let air out when ascending. 3. Fine-tuning your buoyancy underwater with a dry suit a. Dry suit divers adjust their buoyancy by either adding air to their BCDs or their suits. b. The BCD is used primarily on the surface to attain positive buoyancy for comfort and swimming. c. Underwater, add air to the dry suit instead of the BCD. You add air to the dry suit to: • Avoid potential suit squeeze problems. • Easily dump air during ascent or in an emergency (you don’t have to vent air from both your BCD and your suit – avoids confusion). 4. Fine-tuning your buoyancy underwater using breath control. a. Your breathing pattern affects your lung volume, and lung volume affects buoyancy. b. When you’re neutrally buoyant underwater, you rise slightly as you inhale and sink slightly as you exhale. Because of this, you can make minor depth adjustments using breath control. c. Once you’re neutrally buoyant you shouldn’t have to use your BCD for minor depth adjustments. Fine-tune your buoyancy using breath control. D. Peak Performance Buoyancy fundamentals – weight position and distribution. Learning Objectives. By the end of this topic, you will be able to: • Position and distribute weight for greater control in the water. 1. Proper weight position and distribution gives you greater control in the water. Different diving applications require different positioning and distribution. • Example: A photographer working along a wall may prefer a head-up position, while a photographer working near the bottom may prefer a slightly head-down, feet-up position. a. Typically, you’ll want to position and distribute your weight so you swim horizontally – neither head-up nor head-down. Specialty Course Instructor Outline 8 • This minimizes water resistance (drag) and reduces fatigue. • Position your weights away from your spine, more toward your sides and stomach. This helps maintain a face down, horizontal position. b. Head-up, feet-down position for wall diving – position weights toward the middle of your stomach (particularly if you’re wearing a heavy tank). c. Slightly head-down, feet-up position – move tank higher or lower in the BCD or distribute weights more toward chest away from hips. 2. Other tips a. If your legs and feet rise uncomfortably while diving consider: • Switching to fins that don’t float or weigh more • Using ankle weights b. Consider using an integrated weight system – BCD and weights integrated into one unit. • Load all weight into an integrated BCD or divide your weight between the BCD and a weight belt. • Dry suit divers find that loading half their weight in an integrated BCD and half on a weight belt distributes the lead comfortably. E. Peak Performance Buoyancy fundamentals – streamlining Learning Objectives. By the end of this topic, you will be able to: • List four reasons for being streamlined while diving. • Describe how a streamlined diver looks while underwater. 1. Reasons to be streamlined while diving: a. Encourages efficient kicking style. b. Comfort c. Reduces energy needed to move through the water d. Helps keep equipment and body off the bottom, preserving aquatic life 2. Avoid overweighting a. Overweighting drags down the lower half of your body. b. Causes you to add air to your BCD to compensate. This floats your upper half, keeping you from attaining a streamlined position in the water. 3. Swim through the water as horizontal as possible. 4. Neatly attach all hoses to the BCD; keep them tucked close to your body. Secure: Peak Performance Buoyancy 9 a. Alternate air sources (in the triangle formed by your chin and lower corners of your rib cage). b. BCD inflator hose c. All gauges/computers d. Accessories – slates, lights, dive tables, etc. e. Straps – fins, knife, BCD, mask, etc. 5. Use the weight positioning and distribution techniques discussed previously to help you streamline your body underwater. F. Peak Performance Buoyancy fundamentals – visualization Learning Objectives. By the end of this topic, you will be able to: • Use visualization techniques to help you relax, establish a comfortable breathing pattern and move more gracefully through the water. • Use visualization techniques to achieve Peak Performance Buoyancy. 1. Many sports and recreational enthusiasts attain peak performance by visualizing themselves performing their best. 2. To help you relax before a dive, visualize yourself underwater: a. Using your equipment. b. Aware of your surroundings c. In control of your buoyancy 3. Think about relaxing – breathing slowly and deeply. 4. To help you establish a comfortable breathing pattern while diving, picture yourself moving calmly and confidently through the water. 5. Practice – visualize Peak Performance Buoyancy by retracing your last dive. G. Peak Performance Buoyancy fundamentals – staying physically fit Learning Objectives. By the end of this topic, you will be able to: • Explain how being physically fit helps you attain and maintain Peak Performance Buoyancy. 1. Your physical well-being plays an important role in Peak Performance Buoyancy. 2. Staying physically fit allows you to increase stamina, boost your energy level and make breath control easier. 3. Staying in shape helps you avoid getting winded as easily, assisting with breath control. This allows you to fine-tune your buoyancy more efficiently. Specialty Course Instructor Outline 10 H.

Dive One Dive One is the first dive of the Specialty Course, and may also be conducted as an Elective Dive for the PADI Adventures in Diving program. Buoyancy Clinic to PADI Members: PADI Divemasters may conduct the knowledge portion of this specialty (IV. Course Overview and Peak Performance Buoyancy Fundamentals) and Dive One as part of a buoyancy clinic. The Project A.W.A.R.E. certificate is available from PADI for participant recognition upon completion of the clinic. B. Dive Two Dive Two is conducted to complete the Peak Performance Buoyancy Specialty course. C. Additional dives (confined or open water training) may be added at the discretion of the PADI Instructor conducting the specialty course. D. Conduct a thorough knowledge orientation/review and dive briefing. The better the briefing, the more smoothly the dives will proceed. E. Make the dives fun and include buoyancy games. F. Consider having a variety of weight systems, buoyancy related accessories and BCDs for students to try. Students who have not purchased these items may appreciate the opportunity to try them prior to selection. Remember, learning buoyancy control is a two step process – owning their own equipment and then practicing buoyancy control with that equipment. Peak Performance Buoyancy 11 VI. Open Water Dives Skills and procedures different from other PADI Standardized Specialty Dives appear in boldface type. A. Dive One Performance Requirements. By the end of Dive One, you will be able to: • Rig a weight system with the following considerations in mind: 1. Use an estimated amount of weight from PADI’s “Basic Weighting Guidelines.” 2. Position and distribute the weight for comfort and desired body position (trim) in the water. • Use visualization techniques prior to the dive to help you relax, establish a comfortable breathing pattern and move gracefully through the water. • Conduct a buoyancy check by adjusting the amount of weight worn to achieve neutral buoyancy at the surface of the water with the BCD deflated. • Make a controlled, slow descent to the bottom and, if needed, adjust for neutral buoyancy using the BCD. • Adjust for neutral buoyancy at a predetermined depth. • Using buoyancy control, hover motionless (without kicking or hand movement) underwater for at least one minute. • Swim horizontally, while neutrally buoyant without touching the bottom or breaking the surface of the water with equipment or body. • Make minor depth adjustments using breath control only. • Demonstrate efficient fin kicks, using long, slow strokes and gliding. • Navigate an obstacle course without touching obstacle items, the bottom or breaking the surface. • Adjust weights (trim) and practice hovering in different positions – vertical, horizontal, feet slightly elevated and head slightly elevated. 1. Assembly of weight system and use of PADI’s “Basic Weighting Guidelines.” a. Estimate amount of weight needed for the dive – base determination on your build, water medium (salt or fresh), equipment used, estimated weight change due to air consumption. [Have students use the “Basic Weighting Guidelines” in the Peak Performance Buoyancy booklet when estimating the amount of weight they’ll need.] b. Assemble weight system. Note method of ditching weights in an emergency. Specialty Course Instructor Outline 12 to PADI Members: Allow students time to set up their weight systems. Emphasize proper weight positioning, distribution, trim, securing weights, right hand releases and ditching in an emergency. Students with integrated BCD weight systems should know how to a) load weights, b) release weights in an emergency, and c) how to reload the weights using the manufacturer’s instructions. 2. Visualization practice. Just before suiting-up, take time to visualize yourself attaining Peak Performance Buoyancy while diving. 3. Getting in the water, buoyancy check and descent. a. Put on all equipment for the dive – full scuba. Conduct the PADI Predive Safety Check with buddy (Begin With Review And Friend). Make sure all loose equipment (alternate air sources, gauges, BCD hose) is secured – don’t allow equipment to dangle, streamline equipment against the body. b. Make appropriate entry. c. Conduct buoyancy check. Add or subtract weight as needed. d. Buddy teams descend in water too deep to stand in. You should be able to descend without kicking – just by exhaling. Concentrate on descending slowly and neutralizing your buoyancy as needed during descent. 4. Hovering to PADI Members: Establishing neutral buoyancy is an important subskill of hovering. Fin pivoting can help students efficiently and easily establish neutral buoyancy. Students having difficulty hovering should be encouraged to establish neutral buoyancy using the fin pivot before attempting to hover. a. If appropriate, establish neutral buoyancy using the fin pivot. b. Once neutral buoyancy is established, hover for one minute without fin movement or hand movement. During the hover practice breath control to make minor depth adjustments. to PADI Members: Should you choose to conduct buoyancy clinics in a pool environment, use item 5 below. Should you choose to conduct the Peak Performance Buoyancy Specialty course or Adventure Dive, use item 6 below. Peak Performance Buoyancy 13 5. Peak Performance Buoyancy game – pool to PADI Members: Use this buoyancy game when conducting a clinic in a pool that has both a shallow section (approximately 1 metre/3 to 4 feet deep) and a deep section (at least 2 metres/6 feet). a. Directly from the hover, swim midwater to the outside edge of the pool with your buddy. Swim underwater from the deep end to the shallow end of the pool, next to the wall. During the swim adjust for neutral buoyancy, concentrate on an efficient kicking style, practice gliding after kicks and streamline your body/equipment as much as possible. b. Goal: Complete two back-to-back trips around the outside edge of the pool (alternately moving from deep to shallow water) without any part of your body or equipment touching the bottom of the pool or breaking the surface of the water. to PADI Members: It may take some individuals many trips around the outside edge of the pool to meet the objective. That’s okay, allow them as much time as they need to meet the objective. c. Buoyancy game add-ons: • Swim through an obstacle course with weighted PVC pipe, Hula-Hoops™ or other such devices in the middle of the pool. As a challenge, try to swim through the obstacles without touching them with your equipment or body. • Simulate a safety stop in the deep end of the pool – hover midwater for three minutes. • Practice the following: 1) One-finger push-offs – pretend the bottom of the pool is a dead portion of a reef and practice pushing off with one finger. 2) Sculling forward and backward using minimal hand or fin movement. 3) Dropping weights at the surface. [Do this at the end of the session, just before participants exit the pool. This may be the first time participants have actually dropped weights for practice. However, be cautious of divers under the weights and of damaging pool bottoms. Practice with “soft weights” loaded with lead shot only. Also, help students with integrated BCDs reload weights using the manufacturer’s instructions.] Specialty Course Instructor Outline 14 6. Peak Performance Buoyancy game – open water to PADI Members: Use this buoyancy game when in open water as part of the Peak Performance Buoyancy Specialty course or Adventure Dive. The outline assumes use of an environment that varies in depth. Try to plan the dive so it progresses from the deepest portion of the dive to shallow water. a. Directly from the hover, swim above the bottom. [The swim could be a guided tour by a clinic leader or directed along a marked route.] • During the swim, make minor depth adjustments using breath control only. While swimming, adjust for neutral buoyancy; concentrate on an efficient, relaxed kicking style; practice gliding after kicks; and streamline your body/equipment as much as possible. • Goal: To swim horizontally, while neutrally buoyant, without any part of the body or equipment touching the bottom or breaking the surface of the water. b. Buoyancy game add-ons: • Swim through an obstacle course with weighted PVC pipe, Hula-Hoops™ or other such devices in midwater. As a challenge, try to swim through the obstacles without touching them with your equipment or body. • Practice the following: 1) One-finger push-offs – practice on areas that won’t disturb aquatic life. 2) Sculling forward and backward using minimal hand or fin movement. 3) Streamlining to reduce drag while swimming on the surface. Practice efficient, well paced fin kicks with neutral buoyancy. 7. Ascent a. Ascend at a rate not to exceed 18 metres/60 feet per minute. Determine the rate of ascent using your depth gauge and timer or dive computer with ascent-rate indicator. b. Vent air as needed from your BCD to maintain neutral buoyancy. c. Perform a safety stop at 5 metres/15 feet for three minutes. Maintain neutral buoyancy at the safety stop. 8. Post-dive procedures a. Signal support personnel once on the surface after a dive (if appropriate). b. Conduct a post-dive buoyancy check. Even while wearing a tank low on air, you should still be neutrally buoyant. Peak Performance Buoyancy 15 c. d. e. f. g. Achieve comfortable positive buoyancy using your BCD. Proper exit technique. Check in with the divemaster (if appropriate).

Log dive (PADI Instructor signs log) Specialty Course Instructor Outline 18 Basic Weighting Guidelines How much weight do I need? This is a tough question every diver faces from time to time. Although only a buoyancy check precisely determines the proper amount of weight needed, here are some basic weight guidelines that will get you started. These guidelines are based on individuals of average build, diving in salt water. Lean individuals or individuals diving in fresh water may need less weight, heavy individuals may need more. Basic Guidelines: Exposure Suit Type Begin With 1. Swimsuit or dive skin 0.5 - 2 kg/1 - 4 lb. 2. Thin (3 mm/1/16 inch), one-piece wet suits – shorties or jump suits 5% of your body weight 3. Medium-thickness (5mm/3/16 inch), Two-piece wet suit 10% of your body weight 4. Cold-water (7mm/1/4 inch), two-piece wet suit with hood and boots 10% of your body weight, plus 1.5 - 3 kg/3 - 5 lb. 5. Neoprene dry suits plus 3 - 5 kg/7 - 10 lb. 10% of your body weight, 6. Shell-style dry suits* (using light-weight, nonfoam underwear) 10% of your body weight, plus 1.5 - 3 kg/3 - 5 lb. 7. Shell style dry suits* (using heavy-weight or foam underwear) 10% of your body weight, plus 3 - 7 kg/7 - 14 lb. * Regarding shell-style drysuits – the lead needed beyond 10% of your body weight is primarily determined by the buoyancy of your underwear. The buoyancy of different underwear types varies greatly. Conversion Estimates for Salt or Fresh Water Convert from salt water to fresh water (or vice versa) using the following estimates. Body Weight 45 - 56 kg/100 - 125 lb. 57 - 70 kg/126 - 155 lb. 71 - 85 kg/156 - 186 lb. 86 - 99 kg/187 - 217 lb. Amount of Weight to Add (Fresh Water to Salt Water) or Subtract (Salt Water to Fresh Water) 2 kg/4 lb. 2.3 kg/5 lb. 3 kg/6 lb. 3.2 kg/7 lb. Peak Performance Buoyancy 19 Estimating Weight Change Due to Air Consumption Depending on the type of tank you use, it can become 1-2 kg/3-5 lb. more buoyant by the end of your dive. The popular 80 cubic foot/12 litre tank will become approximately 2 kg/5 lb. more buoyant. To compensate for this increased buoyancy near the end of your dive, you may need to add some weight beyond the basic guidelines above. Additional weight, beyond the guidelines may not be needed for some types of steel tanks. Using the Estimates – Three Examples 1. 2. 3. A diver weighing 70 kg/155 lb. buys a medium thickness, two-piece 5mm/3/16 inch wet suit. Using the estimates above, he decides to begin with 7 kg/15 lb. in salt water or 4.7 kg/10 lb. in fresh water. He plans on using an aluminum 12 litre/80 cubic foot tank, so he adds 2 kg/5 lb. lead to his weight system. To begin his buoyancy check he enters the water with an estimated 9 kg/20 lb. in salt water or 6.7 kg/15 lb. in fresh water. A diver weighing 85 kg/188 lb. travels to a resort, warm-water ocean destination where he decides to dive using nonbuoyant dive skins. Using the estimates above, he decides to begin with 2 kg/4 lb. Since he is a little overweight, he decides to add an additional 0.5 kg/1 lb. The divemaster informs him that the steel tanks supplied by the resort are neutrally buoyant at the end of the dive. With this information he decides conduct his buoyancy check at the beginning of his first dive with a total of 2.5 kg/5 lb. A diver weighing 50 kg/110 lb. buys a shell-style dry suit with heavyweight, cold water underwear. Using the estimates above, he decides to begin with 5 kg/11 lb. in salt water (10% of his body weight) or 3 kg/7 lb. in fresh water, and then adds 5 kg/10 lb. to compensate for the buoyancy of his underwear. This addition brings his total estimated weight requirement to 10 kg/21 lb. in the ocean or 8 kg/17 lb. in fresh water. He plans on using an aluminum 12 liter/80 cubic foot tank, so he adds 2 kg/5 lb. lead to his weight system. To begin his buoyancy check he enters the water with an estimated 12 kg/26 lb. in salt water or 10 kg/22 lb. in fresh water.
