Top 10 Things to Have for Exploring an Underwater Shipwreck

Exploring an underwater shipwreck is one of the most thrilling adventures for scuba divers. It’s a chance to encounter history frozen in time, observe marine life in an eerie new light, and challenge your diving skills in a truly unforgettable setting. But such an extraordinary experience requires extraordinary preparation. Having the right gear not only enhances your journey—it ensures your safety and success beneath the waves.

Whether you’re diving into a sunken cargo vessel, a coral-covered frigate, or a mysterious ghost ship deep beneath the surface, this guide outlines the Top 10 Things to Have for Exploring an Underwater Shipwreck.

1. Scuba Gear

Your scuba gear is your underwater lifeline. It includes essential components like a mask, snorkel, fins, buoyancy control device (BCD), and regulator. Without it, shipwreck exploration is impossible.

A properly fitted mask and fins help with visibility and maneuverability in tight or murky areas. The regulator provides steady airflow from your oxygen tank, and the BCD allows you to achieve neutral buoyancy—a must when swimming around fragile structures without disturbing silt or marine life.

Pro Tip: Invest in high-quality, well-maintained scuba gear. Always do a pre-dive safety check, and never enter a wreck without proper training and certification.

2. Dive Light

Even on sunny days, shipwreck interiors can be pitch black. A powerful, waterproof dive light is critical for visibility inside compartments, passageways, or hulls.

A primary light with high lumens (over 1000) ensures you can see detail clearly, while a backup light adds a layer of safety in case your main light fails.

Use a light with a tight beam for long-range focus and a wide beam for exploring larger interior sections.

Pro Tip: Always carry two dive lights—one main and one backup. LED lights are durable and have long battery lives, ideal for extended dives.

3. Wetsuit

Underwater temperatures can plummet at shipwreck depths. A well-insulated wetsuit protects you from cold, stings, scrapes, and cuts. It also conserves body heat and minimizes fatigue.

Choose a wetsuit thickness based on your destination:

• 3mm for warm water

• 5mm–7mm for temperate to cold conditions

A full-body wetsuit also protects against sharp rusted edges or entanglements often found on old wrecks.

Pro Tip: Pair your wetsuit with a hood, gloves, and boots for full thermal protection and safety.

4. Underwater Camera

Want to share your shipwreck adventure? A high-quality underwater camera captures the mystery, beauty, and marine life within and around the wreck.

Action cameras like GoPro are popular due to their size and depth rating. For professionals, mirrorless and DSLR systems in underwater housings deliver stunning clarity.

Look for features like:

• Depth-rated waterproof housing

• Wide-angle lens for full wreck shots

• Built-in or attachable lights for clarity

Pro Tip: Use a red filter or lighting attachments to enhance colors that are naturally lost at depth.

5. Dive Compass

Shipwrecks can be disorienting, especially large ones with interior passages or multiple decks. A dive compass helps you stay on course and safely navigate your way in and out.

It is crucial for:

• Navigating wreck interiors

• Returning to your starting point or boat

• Avoiding dangerous areas or currents

Mounted on your wrist or console, a dive compass ensures directional awareness even in low-visibility conditions.

Pro Tip: Practice compass navigation in open water before attempting a shipwreck dive.

6. Oxygen Tank & Spare Air

Your oxygen tank provides the air you need to survive at depth. Depending on your dive profile and physical exertion, it determines how long you can safely explore.

But more importantly, having a spare air source—like a pony bottle or backup air supply—can be life-saving in case your primary tank fails or if you get delayed inside the wreck.

Choose tanks with appropriate capacity and always monitor your air gauge during your dive.

Pro Tip: Always dive with a buddy and establish air-sharing procedures before entering a wreck.

7. Dive Gloves

Shipwrecks are filled with jagged metal, encrusted surfaces, and sometimes fishing lines or nets. Dive gloves protect your hands from injuries while offering better grip in tight spaces.

Choose gloves that are:

• Cut-resistant

• Thermal-insulating

• Flexible for mobility

Some shipwreck divers prefer thin gloves for tactile feedback, while others opt for thicker models in colder waters.

Pro Tip: Always be mindful not to touch marine life—gloves are for safety, not exploration by hand.

8. Dive Computer

A dive computer tracks your depth, bottom time, ascent rate, and no-decompression limits. For shipwreck diving, this information is critical due to varying depths and the risk of getting lost or staying too long.

Many dive computers also have compass, gas mix settings, and dive logging features that help you stay within safe parameters.

Always wear it on your wrist or integrate it into your console for easy access.

Pro Tip: Download your dive logs post-dive to analyze performance and improve future dives.

9. Safety Reel & Line

When penetrating a wreck, a safety reel and line can be your most valuable navigation tool. Visibility can rapidly drop due to stirred sediment, making a clear exit path nearly impossible without a guide line.

A safety line:

• Prevents disorientation

• Marks your route in and out

• Helps in team coordination

Use a durable reel with enough line length to match the complexity of the wreck.

Pro Tip: Practice laying and retrieving line in open water before using it inside wrecks.

10. Emergency Signaling Device

Surface conditions can change quickly. An emergency signaling device—like an SMB (surface marker buoy), whistle, mirror, or dive alert system—ensures you can attract attention if separated from your group or boat.

These tools are also crucial in strong currents, low-visibility weather, or when surfacing far from your entry point.

Some electronic versions even send GPS coordinates to the surface crew.

Pro Tip: Never dive without at least one signaling device; store it where it’s easily accessible.

Bonus Tips for Shipwreck Divers

Exploring a shipwreck is different from a recreational reef dive. Here are a few additional tips:

• Get certified in wreck diving or technical diving for complex wrecks.

• Check tide and current conditions before diving.

• Avoid wreck penetration unless you have training and gear.

• Respect marine life—shipwrecks often serve as vibrant ecosystems.

• Use hand signals or underwater communication for safety.

Final Thoughts: Dive Prepared, Dive Smart

A shipwreck isn’t just a pile of rusted metal. It’s a preserved piece of maritime history, an artificial reef, and a home to countless marine species. With the right tools, training, and mindset, exploring these underwater giants can be one of the most exhilarating experiences of your life.

Remember, preparation is everything. The gear you bring will not only elevate your adventure but could mean the difference between a good dive and a dangerous one.

Now grab your gear, buddy up, and descend into the mysteries of the deep.
