Scuba diving has become one of my favorite ways to travel. I've explored wreck sites in Coron, dived around Puerto Galera, and spent time underwater in Tulamben, Bali. Some dives are all about colorful reefs and marine life. Others are about seeing the outside of a historic shipwreck resting beneath the sea. Both make me appreciate how much a comfortable, well-prepared dive setup matters.
As a PADI Open Water Diver, I know I don't need to own every piece of scuba equipment to enjoy a trip. Dive centers can provide rental gear, and that can be a practical choice, especially when I'm flying. But there are a few essentials I pay closer attention to because fit, familiarity, and comfort make such a difference.
Here are 11 scuba diving essentials I look for when planning a mix of wreck and reef diving, from the equipment I rely on underwater to the accessories that make each trip more comfortable.
1. BEST WETSUIT FOR SCUBA DIVING: WHAT I CHOOSE FOR WRECK AND REEF DIVES
My first consideration is always the wetsuit. Tropical water can feel lovely at the surface, but I can still get cold during a longer dive, at greater depth, or after several dives in one day.
For warm-water reef diving, a well-fitting 3 mm wetsuit is a common starting point. If the water is cooler, I'm planning longer or repeated dives, or I know I get cold easily, a 5 mm wetsuit may be more comfortable. These are general options, not fixed rules: I check the actual water temperature and ask the dive operator about conditions before choosing. PADI also emphasizes choosing suit thickness based on water temperature.
For wreck diving, I also prefer the coverage of a full-length suit. It offers a layer of protection against accidental scrapes, although I still keep my distance from rusted metal, sharp edges, and marine life. A wreck isn't automatically colder than a reef—the depth, water temperature, and time underwater make the difference.
What I look for: A snug fit without uncomfortable restriction, full coverage when appropriate, and enough warmth for my planned dives. I also check how the suit affects my buoyancy and weighting.
2. BEST SCUBA DIVING BOOTS: COMFORTABLE PROTECTION FOR BOAT AND SHORE DIVES
Dive boots may not be the most exciting thing to shop for, but they're one of the accessories I wouldn't overlook.
They help protect my feet on boat decks and during suitable shore entries, and they make open-heel fins more comfortable. For a place with a rocky entry, I look for a sole that provides dependable protection and grip. For boat diving, I still want a fit that feels secure without rubbing my heels or toes.
I also check that the boots work with the fins I'll actually use. A thick boot that doesn't fit the fin's foot pocket can be just as inconvenient as a boot that's too loose.
What I look for in boots: Comfortable neoprene, a secure fit, a useful sole, and compatibility with my fins. I always consider the fins and boots together before buying.
3. BEST SCUBA DIVING FINS: EFFICIENT KICKING FOR REEFS AND WRECKS
Fins are the other half of this setup. Good scuba diving fins help me move efficiently through the water without feeling as though I'm working harder than necessary.
When I'm diving around a reef, I want controlled kicks that help me keep my distance from coral and avoid stirring up sediment. Around the outside of a wreck, control matters just as much. I don't want to accidentally kick the structure or disturb the bottom while looking at the details.
I consider both open-heel fins, which are worn with dive boots, and full-foot fins, which can be convenient in some warm-water conditions. I also think about how stiff or flexible a fin feels and whether it suits my leg strength and the current. The best pair for me isn't necessarily the biggest or most expensive one.
What I look for in fins: A secure fit, comfortable kicking, and good control for the conditions and techniques I've been trained to use. Boots and fins have to work together, so I try them as a pair.
4. BEST SCUBA DIVING MASK: CLEAR VISION, PROPER FIT, AND ANTI-FOG COMFORT
If there's one piece of gear where personal fit really matters, it's the mask.
I want to enjoy the small details underwater—from marine life around a reef to the textures and shapes of a shipwreck—without constantly dealing with leaks or an uncomfortable frame. A mask that looks beautiful in a product photo may not fit my face properly, so I always prioritize the seal over the design.
I look for a comfortable silicone skirt, a nose pocket I can reach easily to equalize, and a field of view I like. I also prepare the mask according to the manufacturer's instructions and use a suitable anti-fog product when needed. Some coated lenses require special care, so I don't assume every cleaning method is safe for every mask.
What I look for: A good facial seal, easy equalization, comfortable straps, and clear visibility.
5. BEST SCUBA DIVING BCD: COMFORTABLE BUOYANCY CONTROL AROUND REEFS AND WRECKS
The buoyancy control device (BCD) is a major part of my scuba setup. It helps me manage buoyancy at the surface and underwater, along with proper weighting, breathing, and fin technique.
For both reef and wreck diving, I want a BCD that fits securely and lets me maintain a stable position without fussing with the straps throughout the dive. Good buoyancy is especially important around fragile coral and wreck structures, where keeping a respectful distance matters.
Before entering the water, I check the inflator, deflator, straps, releases, and the overall fit as part of my pre-dive safety checks. I also make sure I know the controls of a rental BCD rather than assuming every model works exactly like one I've used before. I look for secure tank attachment and a lift capacity appropriate to the diving conditions.
What I look for: A comfortable fit, accessible controls, suitable lift, secure tank attachment, and a BCD that has been checked before the dive.
6. BEST SCUBA DIVING REGULATOR: COMFORTABLE BREATHING AND RELIABLE PERFORMANCE
The regulator delivers breathing gas from the cylinder at a usable pressure. I treat it as life-support equipment, not another travel accessory. Whether I'm hovering over a reef or swimming along the outside of a wreck, I want a regulator that breathes comfortably and is professionally maintained.
I need to know where my alternate air source and pressure gauge are, how the hoses are routed, and how to reach everything quickly. I also make sure the regulator and BCD inflator connections are compatible. These checks matter even when I rent the equipment from a dive operator.
I don't buy a regulator just because it's popular online. If I'm choosing my own, I'll ask a qualified dive professional to check configuration, compatibility, servicing requirements, and whether it suits the conditions I actually dive in. I never assume a regulator is ready to use simply because it looks clean.
What I look for: A professionally serviced regulator, reliable breathing, properly configured alternate air source and pressure gauge, and a setup I understand well enough to use as trained.
7. SCUBA DIVING GLOVES: HAND PROTECTION FOR WRECK DIVES AND RESPONSIBLE REEF DIVING
Gloves are one of those scuba accessories I think about differently depending on the dive site. Around a wreck, exposed metal, fishing line, or rough surfaces can create hazards. A suitable pair of dive gloves can add warmth and some protection against an accidental scrape. But gloves are not puncture-proof, and they're definitely not permission to handle a wreck.
For reef diving, the environmental rules matter just as much as comfort. Coral is delicate, and touching it can cause damage even when my hands are covered. Some marine parks and dive operators restrict or prohibit gloves to discourage contact with marine life. Before packing a pair, I check the local rules and listen to the dive briefing.
I would choose the glove material and thickness based on water temperature, dexterity, and the site's guidance. I still keep my hands to myself underwater. Good buoyancy and awareness do far more to prevent contact than simply wearing thicker gloves.
What I look for: A comfortable fit, enough finger movement to operate my gear, appropriate protection, and permission to wear them at the dive site.
8. BEST DIVE TORCH FOR WRECK DIVING: A RELIABLE UNDERWATER FLASHLIGHT
A dive torch, also called an underwater flashlight or dive light, is a particularly useful addition when I'm exploring the outside of a shipwreck. Even during the day, shadows can make parts of a wreck difficult to see. A beam of light can reveal details I might otherwise miss and help restore colors that fade with depth.
I don't choose a torch based on the biggest advertised lumen number alone. I pay attention to the manufacturer's actual depth rating, beam pattern, battery runtime, switch design, and whether I can operate it comfortably while wearing gloves. A secure attachment is useful, but I also want to avoid loose, dangling equipment that could snag.
It is important to say that having a torch does not make wreck penetration safe. Entering a wreck involves an overhead environment, different risks, specialized equipment, and proper training. On a recreational dive within my qualifications, a torch is for viewing accessible exterior details and other approved areas—not a reason to enter dark passages.
What I look for: A genuinely dive-rated light, reliable sealing, useful runtime, a manageable grip, and a suitable beam for the planned dive.
9. BEST DIVE COMPUTER FOR SCUBA DIVING: TRACKING DEPTH, TIME, AND ASCENT
A dive computer is one of the pieces of equipment I want to understand before I even get into the water. It displays important information such as my depth, dive time, and no-decompression status. Many models also show ascent-rate alerts, safety-stop information, and other warnings. Having those details available at a glance helps me follow the dive plan without guessing.
I find a dive computer especially useful on trips with multiple dives in one day. It accounts for my dive history according to its algorithm and settings, although it isn't a guarantee against decompression illness. I still follow my training, the dive briefing, and conservative planning.
When comparing dive computers, I focus on a readable display, straightforward controls, audible or vibration alerts I can recognize, and a dependable battery. I also check the correct breathing-gas setting, units, and personal settings before every dive. If a model is not air-integrated, I still need to monitor my cylinder pressure using the appropriate gauge.
I don't need the most expensive smartwatch-style computer or every advanced feature. I would rather have a reliable dive computer whose information I can understand quickly, even when I'm busy taking in a beautiful reef or wreck.
What I look for: Clear depth and time readings, understandable no-decompression and ascent information, reliable power, and controls I know how to use.
10. WATERPROOF DRY BAG FOR SCUBA DIVING TRIPS: KEEPING MY BOAT ESSENTIALS DRY
An underwater camera is the fun part of my diving checklist. I love being able to bring home a little piece of the experience, especially from trips with beautiful reefs, marine life, and historic shipwrecks. Since I use a DJI Osmo Action for diving content, I also think about how easily a camera fits into my setup without distracting me from the dive.
Before every trip, I check the waterproof rating for my exact camera model and its housing. Different generations have different depth limits, and a camera's bare-unit rating isn't necessarily the same as the rating with an approved underwater case. I inspect seals and closures according to the manufacturer's instructions, check the battery and storage, and secure the camera appropriately.
For reef footage, I like wide scenes that show the underwater landscape without chasing marine life. For wrecks, I prefer calm, steady movement that lets the structure tell its own story. A dive torch or video light can help in darker conditions, but a beautiful shot is never worth losing awareness of my depth, gas supply, buddy, or surroundings.
What I look for: A suitable depth-rated housing, simple controls, good stabilization, useful battery life, and a setup I can manage while maintaining good buoyancy.
11. BEST UNDERWATER ACTION CAMERA FOR SCUBA DIVING: CAPTURING WRECKS AND MARINE LIFE

| A NOTE ABOUT WRECK DIVING
Seeing historic wrecks underwater is one of the things that makes diving so memorable for me. But there's an important difference between exploring the outside of a wreck and entering one. Wreck penetration creates an overhead environment and requires specialized training, planning, and equipment. I stay within my certification and experience limits and follow the guidance of qualified dive professionals.
The same care applies around reefs. I watch my buoyancy and fin position, avoid touching marine life, and give both coral and wreck structures space.
| FINAL THOUGHTS: I CHOOSE FIT AND FAMILIARITY FIRST
My favorite part of scuba diving will always be the experience itself: the quiet, the marine life, and the feeling of discovering another world beneath the surface. The gear is there to help me enjoy that experience safely and comfortably.
If I'm prioritizing what to own first, I usually think about the pieces where fit and familiarity make the biggest difference, such as my mask, boots, fins, and exposure protection. For larger life-support equipment, renting from a reputable dive center can still be a sensible option until I'm ready to invest in gear that's right for me.
Whether my next dive is over a colorful reef or beside a shipwreck, I want to feel prepared—not overloaded with things I don't need.
Happy bubbles and safe diving!
