Staying fit for scuba diving: How to be? When people think of scuba diving, they often imagine slow, weightless drifting through coral gardens or exploring peaceful shipwrecks. It seems like a relaxing, low-effort activity — and it can be. But behind every safe, enjoyable dive is a diver whose body is capable of handling the unique physical and environmental demands of the underwater world. This is where the concept of “dive fitness” becomes crucial.

In this post, we’ll explore what it truly means to be “dive fit,” how physical fitness affects scuba safety, and how enrolling in an Advanced Open Water Course can be a great way to challenge your body and mind while improving your dive readiness.

Why Fitness Matters for Divers

Scuba diving is more physically demanding than many people realize. Lifting gear, swimming against currents, controlling buoyancy, climbing dive ladders, managing thermal stress, and reacting to emergencies — all require a certain level of strength, endurance, coordination, and mental clarity.

According to the Divers Alert Network (DAN), a significant number of diving incidents stem from inadequate fitness, especially cardiovascular fitness. Even recreational dives can turn physically challenging due to sudden weather changes, strong surface waves, or long surface swims. In these situation

Key Areas of fit for scuba diving

Dive fitness isn’t about having a six-pack or running marathons. It’s about conditioning your body for the specific movements and stresses of diving. Here are the most important aspects of fitness that every diver should consider:

1. Cardiovascular Endurance

Heart and lung fitness are critical. Diving places demands on your cardiovascular system, especially when you’re swimming against the current or performing repetitive dives. Good cardio fitness improves your air consumption, reduces fatigue, and helps you manage stress underwater.

2. Muscular Strength

You’ll often carry 15–25 kilograms of equipment — tanks, weights, and gear — to and from the dive site. Muscle strength, particularly in the legs, core, and shoulders, helps you handle this gear safely and minimizes the risk of injury. It also supports proper finning technique and posture during the dive.

3. Flexibility and Joint Mobility

Good range of motion makes it easier to reach your valves, adjust the gear, or maintain streamlined trim. Tight shoulders or hips can hinder your efficiency and cause discomfort, especially on longer dives.

4. Balance and Coordination

From shore entries to backrolls off a boat, diving involves body awareness and stability. Better balance helps prevent slips, stumbles, or awkward gear handling. It’s especially important for photographers or those planning to take the Advanced Open Water Diver course, where specialty dives like peak performance buoyancy or navigation test your precision underwater.

5. Mental Fitness

Stress, anxiety, or poor focus can lead to poor decision-making and accidents underwater. Fitness also means having the mental stamina to stay calm under pressure, remember procedures, and communicate clearly.

How Fit Do You Need to Be?

You don’t need to be a professional athlete to dive, but you should be able to comfortably:

Swim 200 meters without stopping (or 300 meters with mask, snorkel, and fins)

Tread water for 10 minutes

Carry your equipment short distances without gasping for air

Perform a controlled ascent or swim in mild currents without panicking

These minimums help ensure your safety and the safety of your buddy.

Warning Signs of Poor fit for scuba diving

Even certified divers sometimes overestimate their abilities. Here are red flags that suggest you might need to improve your fitness:

You’re short of breath during surface swims

You avoid diving from shore due to the effort required

You cramp easily underwater

You need help carrying your gear every time

You struggle to maintain neutral buoyancy due to lack of core control

If any of these sound familiar, it might be time to reevaluate your dive fitness program.

How to Improve Dive Fitness

You don’t need a complicated routine. Just focus on a few basic areas that support your diving lifestyle.

1. MONDAY – Cardio (Walk/Hike/Bike) + Yoga walking option for biking

2. Tuesday – Swimming + Breathing

3. Wednesday – Strength + Core + Stretch

4. Thursday or Friday – Swimming + Mobility

The Bottom Line

Being “dive fit” doesn’t mean training like an Olympian. It means honoring the physical nature of diving and preparing your body accordingly. This preparation doesn’t just make your dives easier — it makes them safer and more enjoyable.

Whether you're returning to diving after a break, taking your Advanced Open Water course, or planning a dream dive trip, take time to check in with your body. A fitter diver is a safer diver — and a more confident one, too.

So lace up those sneakers, grab your fins, and keep your body as ready as your dive gear.

When you’re a scuba diver, BCD—is a best friend
When you’re a scuba diver, BCD—is a best friend. It keeps you neutrally buoyant, lets you hover effortlessly, and plays a vital role in your safety and comfort beneath the surface. But not all BCDs are created equal, and choosing the right one for your dive style can be overwhelming, especially with terms like "jacket," "wing," and "hybrid" floating around dive shops and forums.

In this post, we’re demystifying BCDs. We’ll break down the types, how they function, and their pros and cons so you can choose the BCD that fits your diving lifestyle, body type, and experience level.

What is a BCD?

A BCD (Buoyancy Control Device) is a piece of scuba gear that allows divers to control their buoyancy. By adding or releasing air from the BCD’s bladder, you can achieve neutral buoyancy underwater, positive buoyancy on the surface, or negative buoyancy for descents.

Beyond buoyancy control, a BCD also:

Holds your tank in place

Provides D-rings or pockets for accessories

Keeps your gear streamlined

Offers surface flotation when needed

BCD design has evolved, resulting in three main types: jacket-style, back-inflate wing, and hybrid BCDs.

Jacket-Style BCDs

The most commonly used BCD—especially in recreational diving and dive training—is the jacket-style.

Features:

Air bladders are positioned around the sides and back

Worn like a vest or life jacket

Often includes integrated weight pockets

Multiple large pockets and D-rings for gear storage

Pros:

✅ Very stable on the surface—ideal for new divers
✅ Comfortable and familiar design
✅ Easy to don on and off
✅ Integrated weights reduce reliance on weight belts

Cons:

❌ Inflates around the chest, which can squeeze or feel restrictive
❌ Can ride up slightly on the surface
❌ Less streamlined for horizontal trim underwater
❌ Limited customization for tech setups

Best for:

Beginner divers

Casual recreational divers

Warm water diving

Resort or rental gear

Back-Inflate Wing BCDs

Also known simply as “wings,” this style positions the air bladder solely behind the diver, around the tank.

Features:

Air bladder located entirely on the back

More streamlined and balanced for horizontal diving

Common in technical and cold water diving

Often used with a backplate and harness system

Pros:

✅ Excellent trim and buoyancy control
✅ Less squeeze around the torso
✅ Streamlined profile—perfect for drift, wreck, and tech diving
✅ Highly customizable for individual needs
✅ Modular components (replace parts as needed)

Cons:

❌ May push diver forward on the surface—uncomfortable for new divers
❌ Less storage; may require additional gear pockets or clips
❌ Takes more time to master buoyancy
❌ Not all have integrated weights (requires a separate weight belt)

Best for:

Intermediate to advanced divers

Cold water and drysuit diving

Technical or cave diving

Divers who prioritize trim and streamlining

Hybrid BCDs

The hybrid combines features from both jacket and wing designs, aiming to provide the best of both worlds.

Features:

Bladder is primarily on the back, but may extend partially around the sides

More surface stability than a full wing, but more streamlined than a jacket

Often includes weight integration and ample pockets

Pros:

✅ Balanced buoyancy and surface comfort
✅ Improved horizontal trim compared to jackets
✅ Familiar fit with better in-water positioning
✅ Good for travel or multi-environment diving

Cons:

❌ May still push you forward slightly on the surface
❌ Not as trim-focused as a full wing system
❌ Slightly more expensive than basic jackets

Best for:

Recreational divers looking for trim and comfort

Divers transitioning from jacket to wing

Travelers who dive in varied conditions

Specialty Options: Travel and Tech BCDs

Travel BCDs:

Lightweight and compact

May sacrifice padding or pockets for weight savings

Ideal for dive vacations or carry-on-only travel

Technical BCDs:

Typically wing-style with steel/aluminum backplate

Designed for twin tanks, stages, sidemount, or rebreather setups

Modular and extremely rugged

Choosing the Right BCD for You

Ask yourself these key questions:

Where do you dive?

Warm, calm waters like in Anilao = jacket or hybrid

Drift like Puerto Galera = wing-style

Deep Pe*******on dive sites like in Subic Bay = wing style

Cold sites definitely wing because of your drysuit

How experienced are you?

Beginners often prefer jacket-style for its stability

Advanced divers may appreciate wings for precision and control

What gear do you carry?

If you need pockets and storage, jacket or hybrid may work better

If you carry slates, DSMBs, reels, or cameras, you’ll appreciate multiple D-rings or custom harness systems

Do you travel often?

Choose a lightweight BCD or travel-specific model to reduce baggage costs

Do you want modularity?

Wings and backplate systems let you replace parts individually (harness, bladder, plate, etc.)

Do you prefer comfort or performance?

Jacket = comfort and ease

Wing = performance and control

Hybrid = balance of both

Final Thoughts: Which BCD Should You Choose?

There is no one-size-fits-all when it comes to BCDs. The best BCD is the one that fits your body, your dive style, and your goals underwater.

Go for a jacket if you want easy buoyancy and surface comfort.

Choose a wing if you’re into streamlined diving and perfect trim.

Opt for a hybrid if you want a versatile blend of both.

Before buying, always try on your BCD with your gear. Do a proper weight check, test your trim in a pool or controlled environment, and pay attention to how the BCD supports your tank and fits around your body. Better yet, rent different types and log a few dives in each to find your best match.

If you're in the market for a new BCD or just want to talk through your options with an experienced diver, reach out to us at Scuba Sirens—we’re always happy to help you make the right choice for your diving adventures.

What You Need to Know About the DAN Decompression Sickness Health and Reference book is it is the most reliable source of information about DCS. Download the booklet by clicking on the link below.
https://dan.org/wp-content/uploads/2020/07/decompression-sickness-dan-dive-medical-reference.pdf
Decompression sickness (DCS) is a serious but preventable risk in diving. Every dive plan should include strategies to minimize its occurrence. This booklet offers up-to-date insights into the causes and mechanisms of DCS, its common symptoms, recommended treatment, and essential prevention practices.

This 40-page book aims to help prevent decompression sickness (DCS) from affecting as many scuba divers as possible. DAN explains in clear terms how a diver's body responds to changes in pressure, tissue tension, and gas exchange at depth. As pressure increases, inert gases like nitrogen dissolve into body tissues. The deeper the dive, the faster the rate of gas absorption. Upon ascent, the surrounding pressure decreases, and these dissolved gases begin to leave the tissues. A slow, controlled ascent allows for safe off-gassing, while a rapid ascent increases the risk of DCS. Gas exchange is driven by pressure gradients, with the lungs serving as the primary site for eliminating inert gases. Saturation is reached when tissue gas levels match the ambient pressure, but achieving full saturation requires extended time at depth.

The book also introduces the concept of tissue compartments, a cornerstone of decompression theory. These compartments are mathematical models that estimate how different body tissues absorb and eliminate gases at different rates. In each half-time period, a tissue takes up or releases half the difference in gas pressure. Supersaturation occurs during ascent and, if excessive, can lead to gas bubble formation and DCS. Dive tables and dive computers rely on these models to determine safe ascent limits, but actual decompression risk is influenced by real-world factors such as temperature, exertion, and individual physiology. For this reason, conservative diving practices are essential.

DAN also reminds divers that, despite their sophistication, dive computers have real-time limitations based on the data they can process. Chapter 2 outlines key guidelines for using your dive computer effectively and highlights the role of dehydration, a major contributor to DCS risk that no current dive computer can measure directly.

Dehydration is an internal state that requires monitoring factors like fluid balance, blood concentration, and core body temperature—none of which dive computers can detect. Although some smartwatches are exploring hydration tracking through skin sensors, this technology has yet to be incorporated into dive computers. Additionally, factors such as breathing dry gas and diving in cold environments can accelerate fluid loss, yet these too are not accounted for in most dive algorithms.

Still, some advanced dive computers offer helpful health tracking features. For example, the Garmin Descent Mk2i can monitor heart rate and skin temperature (with a compatible chest strap), provide hydration reminders between dives, and estimate workload and stress. These tools, while indirect, can support better self-awareness and safer diving decisions.

DAN also shares practical advice for using your dive computer wisely. Relying on your device isn’t inherently unsafe, as long as you recognize its limitations. Pay attention to alerts, use it as more than a logbook, and most importantly, be ready to say, “Let’s stop the dive” if something doesn’t feel right or your computer malfunctions. Your awareness and training are always your best safety tools.

In addition to foundational dive science and computer use, this book offers reliable insight into more advanced topics. Chapter 3 helps divers and dive professionals recognize the signs and symptoms of DCS, distinguish it from other conditions through differential diagnosis, and respond quickly. Chapter 4 covers vital steps in treating DCS, including on-the-scene first aid, subsequent medical evaluation, hyperbaric oxygen therapy, in-water recompression, and a list of essential emergency resources. Finally, Chapter 5 explores the factors that contribute to DCS, such as workload, thermal stress, air travel after diving, fitness to dive, hydration, gas mixtures, carbon dioxide levels, PFO (Patent Foramen Ovale), and other physiological and environmental influences.

Whether you're a new diver trying to understand your body underwater or an experienced one seeking to refine your safety practices, this book delivers the practical, science-backed knowledge you need to dive smarter and safer.

Mask Fogging: How to Prepare a New Dive Mask for Clear Vision Underwater

One of the most crucial steps after buying your first personal scuba gear is properly preparing your mask. Few things are more annoying than gearing up for a dive—excited to explore a colorful coral reef or meet a curious sea turtle—only to have your mask fog up repeatedly.

Whether you’re a brand-new diver or have hundreds of dives under your belt, a foggy mask can seriously impact your experience. It disrupts your enjoyment, compromises your safety, and makes underwater photography nearly impossible.

The good news? You can prevent mask fogging entirely.

In this comprehensive guide, you’ll learn exactly how to treat your new mask and keep your vision clear on every dive.

05/07/2025

Mask Fogging:How To Prepare A New Mask

Mask Fogging: How to Prepare A New Mask for Diving is one of the most important first steps after you buy your first personal scuba equipment. There’s nothing more frustrating than trying to enjoy a vibrant coral reef or a curious sea turtle, and your mask keeps fogging up. Whether you’re a beginner or a seasoned diver, a foggy mask can ruin your dive experience, hinder your safety, and make underwater photography nearly impossible. But the good news? Fogging is completely preventable.

This comprehensive guide walks you through how to keep it crystal clear during every dive.

Mask Fogging: Why It Happens

Mask fogging is primarily caused by condensation, the difference in temperature between the inside of your mask and the water outside. But there's more.

The Real Culprit: Factory Silicone

New masks have a thin layer of invisible silicone residue from the manufacturing process. This layer encourages fog to stick to the lenses. Until it’s properly removed, even the best anti-fog solution won’t help much.

How to Prep a New Mask (and Stop Fog )

1. The Toothpaste Method

Use a non-gel, non-whitening toothpaste. Here's how:

Squeeze a small amount onto each lens (inside only).

Rub it in gently using your fingers or a soft cloth for 2-3 minutes.

Let it sit for at least 30 minutes.

Rinse with warm water.

Repeat 2–3 times before your first dive.

To effectively clean a new mask, use a non-gel, non-whitening toothpaste—these varieties are gentle yet abrasive enough to break down the silicone residue. Make sure to use toothpaste in paste form, not gel, and avoid any whitening formulas. Whitening toothpastes often contain tiny abrasive particles or crystals designed to polish stains off teeth. While effective for dental use, these particles can scratch the lens of your mask, especially if it's made of tempered glass or has special coatings. Using a plain, non-whitening paste ensures a gentle clean that removes the silicone residue without damaging your mask.

Apply a small amount to the inside of each lens, then use your fingertips or a soft cloth to gently rub the paste across the surface for two to three minutes. Once scrubbed, let the toothpaste sit on the lenses for at least 30 minutes to allow it to work. Afterward, rinse thoroughly with warm fresh water. For best results, repeat this cleaning process two to three times before your first dive to ensure all residue is removed.

🧼 This breaks down the silicone layer, allowing your anti-fog treatments to work.

2. Always use a Defogger

After the initial cleaning with a mask scrub or non-abrasive toothpaste, apply a reef-safe commercial defogger such as 500psi or Frog Spit. These products are biodegradable and gentle on marine life. Simply apply a drop or two inside the lens, spread evenly with your finger, and rinse lightly with fresh water—just enough to leave a thin film. Avoid touching the inside of the mask afterward. With proper prep, you'll enjoy clear, fog-free dives.

500 Psi

Mask Defogger is reef-safe and biodegradable—designed to be gentle on marine environments while delivering long-lasting anti-fog performance.
✅ Key Points:

Biodegradable & non-toxic: The 12 oz instructor version is explicitly described as biodegradable and “safe for the environment, so you can protect our reefs while diving” (scuba.com).

Trusted diver favorite: On Reddit, many divers prefer 500 psi over alternatives, with comments like: “500 PSI is great!”
“It just works so well.” (reddit.com)

Usage Tips:

Apply a thin layer inside dry lenses before diving.

Rub gently with fingers, then rinse lightly—saving enough coating for effective defogging.

Avoid over-rinsing to preserve longevity—it often lasts through 3 dives per application (reddit.com, aquanauticsdive.com).

🧪 History & Background

Founded in 1994, 500 PSI introduced a proprietary mask defog formula as its flagship product, earning a loyal following for its effective prep and long-lasting clarity. The original gel/paste consistency—similar to toothpaste—is intentional: it cleans as it defogs, prepping the lens while leaving behind a durable anti-fog layer that typically lasts through three dives per application

⚙️ Formula & Features

This is a biodegradable mask defogger, labeled reef-safe to protect marine ecosystems scuba com+1scuba.com+1.

Sold in 2 oz, 4 oz, and 12 oz bottles, it’s available with or without a convenient carabiner cap scuba.com+3scuba.com+3amazon.ca+3.

The gel-like texture not only defogs but also cleans lenses post-dive, helping to remove oil and residue.

🗣️ User Reviews & Community Feedback

👍 Strong Praise from Divers

On Reddit, the /r/scuba community shared overwhelmingly positive reviews:

“500 PSI is great!”
“I have tried a few different brands and 500 PSI has worked better than Spit, Sea Gold, Stream2Sea…” amazon.ca+11reddit.com+11reddit.com+11

“5‐10% dish soap… baby shampoo… works great. Save on soap in the shower.” — context praising simple reef-safe solutions, but still singling out 500 PSI for effectiveness compared to others amazon.com+3reddit.com+3reddit.com+3.

🌊 Performance & Longevity

Shoppers and dive shops note its long-lasting clarity:

“One application works for at least three dives in a day” scuba.com+3scuba.com+3divers-supply.com+3.

Divers Supply notes its toothpaste-like consistency makes it “the most effective defog available” amazon.ca+15divers-supply.com+15reddit.com+15.

💡 Pro Tips

Use small amounts—a little goes a long way and prevents streaks.

Rub thoroughly, let it dry into a film, then rinse lightly before your dive.

Expect 2–3 dives per application; reapply if clarity fades.

Verdict

500 PSI Mask Defogger earns top marks for its effective, long-lasting performance and reef-friendly formula, with the bulk of feedback from real divers backing its reliability. Just be sure not to over-apply, and it’ll serve you well.

Frog Spit Anti‑Fog

🐸 History & Background

Frog Spit emerged around the mid‑2010s as an eco-friendly alternative in the anti-fog market. Initially showcased at dive expos like DEMA, it quickly gained attention for its “no-rinse” formula and biodegradability (reefbuilders.com). Packed in a distinctive 2-oz bottle or convenient travel-sized wipes, Frog Spit was designed to offer divers a simple, reusable solution that works on both glass and plastic lenses (extremesportsscuba.com).

⚙️ Formula & Features

Highly concentrated: Only one drop per lens is needed, creating a thin, dry film that doesn’t require buffing or rinsing (reefbuilders.com).

Eco-conscious design: Water-soluble, biodegradable, and free from silicone, alcohol, or petroleum distillates—suitable for marine environments (diversdestinationla.com).

Versatile use: Works on dive masks, snorkel goggles, helmets, face shields, and more, in both warm and cold climates (scubatoys.com).

Pleasant scent: Subtle tropical fragrance enhances user experience without overpowering.
🗣️ User Reviews & Community Feedback

👍 Positive Experiences

Reef Builders (DEMA 2017) highlighted its “stop-the-fog” capability and biodegradability (reefbuilders.com).

On ScubaBoard, a user shared a detailed review after testing it over several dives, valuing its consistency and convenience (scubaboard.com).

Reddit /r/scuba divers mentioned Frog Spit as being effective enough to beat other popular products: “Frog Spit is great for the fog” (reddit.com).

It’s also praised beyond diving—used by firefighters, motorcyclists, and industrial-wear professionals for dependable, long-lasting defogging.

💡 Best Practices

Apply just one drop per lens, spread evenly, and allow to dry fully before diving.

No buffing or rinsing needed—use the mask dry for optimal clarity.

Reapply if clarity diminishes; many divers report 2–3 dives per application.

Keep a travel tube in your dive bag—it’s compact and leak-proof.

Verdict:

Frog Spit is a highly effective, user-friendly, and environmentally responsible defogging solution. Its minimalist formula and positive feedback from divers and professionals alike make it a top choice if you're looking for a reliable way to keep your vision clear underwater.

🔥 WARNING: Flame Treatment Not an Option

While some experienced divers still use a lighter to “burn off” the factory silicone layer inside a glass dive mask, this method comes with serious risks:

❌ Here's Why You Should Avoid Flame Treatment:

Modern masks often have coatings (anti-reflective, UV, or mirrored) that can be damaged or destroyed by flame.

Many masks (especially budget-friendly ones) now use polycarbonate or tempered lenses with plastic blends, not pure glass—which can melt or warp.

If done improperly, flame treatment can void the warranty, damage the skirt, or crack the lens.

Mask Anti-Fog Solutions: What Actually Works?

1. Commercial Anti-Fog Drops or Sprays

Brands like Octo gear, Frogspit are easy to use.

Apply before your dive, let it sit for 30 seconds, rinse briefly, then wear the mask.

2. Baby Shampoo

Mix a drop of tear-free baby shampoo with water (1:1).

Apply to the inside of the lens and rinse lightly.

Cheap, reef-safe, and very effective.

3. Saliva Method (aka Spit)

A traditional method used by many divers.

Spit onto the lens, rub gently, and rinse.

While convenient, it’s less effective on new or unprepped masks.

4. Mask Scrub Gels

Specially made mask scrubs help remove film and prepare the lens for anti-fog application.

Often used as a pre-treatment for brand new masks.

Daily Dive Prep: Routine to Keep Your Mask Clear

Rinse your mask in freshwater before each dive.

Apply anti-fog solution (or baby shampoo).

Rinse gently—don’t over-rinse.

Avoid touching the inside lens afterward.

Don’t leave the mask in the sun—it can warp the skirt and degrade the lens coating.

During the Dive: What to Do if Fog Appears

Stay calm. Fog isn’t dangerous, but it’s annoying.

Slightly flood your mask with water, look down, and swish your head to let water wash the fog.

Clear the mask by exhaling through your nose while tilting your head back.

Some divers do a quick rinse like this when starting a dive—just to be sure.

Special Tips for Photographers and Instructors

Use black skirt masks to avoid glare during filming or teaching.

Anti-reflective coatings on some masks help with better light transmission.

Carry a backup mini mask in your BCD pocket just in case your main mask becomes unusable.

What to Avoid

Dish soap: Can leave residue that irritates eyes and harms marine life.

Bleach or vinegar: These are too harsh for silicone skirts and lens coatings.

Rubbing the lens with sandy fingers: Scratches reduce visibility and fog treatments’ effectiveness.

Frequently Asked Questions (FAQs)

Q: How often should I use toothpaste or flame treatments?

Toothpaste is an alternative to defog, but nothing beats the actual defogger.

Never use Flame treatments

Q: Is baby shampoo safe for the ocean?

Yes, if it’s biodegradable and tear-free. Use only a drop, and rinse away from the reef when possible.

Q: Why does my mask fog even with anti-fog solution?

If brand new, it will take a few dives to clear out leftover factory silicone. Do not use flame, but patiently wash and rewash your mask.

Do not touch the inside lens after applying the solution. Once it’s treated, leave it with the rest of the dive equipment, avoiding touching the inside of the lens as much as possible.

Q: Can I wear makeup or sunscreen under the mask?

Ideally no. Oils from makeup or lotion affect the seal and can contribute to fog. Use reef-safe sunscreen well before your dive and let it absorb.

How to Store and Care for Your Mask

Proper mask care prolongs its life and maintains performance.

Rinse thoroughly with fresh water after each dive.

Store it dry, away from sunlight and heat.

Use a hard case or mesh bag to avoid scratches.

Don’t leave your mask hanging from the snorkel or looped on a tank—this can warp the silicone over time.

Final Thoughts: Your Dive Mask Is an Investment

A good dive mask should last years and become your trusted companion underwater. Selecting one that fits well, prepping it correctly, and maintaining it with care ensures fog-free dives and clear memories.

Remember: the ocean is already mysterious—don’t let a foggy mask make it even more so.
