Beyond the Basics: 4 Pieces of Safety Gear You Should Add to Your Scuba Kit

You’ve earned your certification, logged your first few incredible dives, and assembled your core life support equipment. You have your mask, fins, BCD, and regulator system. You feel ready to explore. But as you progress from a newly certified diver to an experienced one, your mindset shifts from simply diving to diving smarter and safer.

True confidence underwater doesn't just come from knowing how to breathe and swim; it comes from being prepared for the unexpected. While major incidents are rare, minor issues can and do happen. Being equipped to handle them turns a potential problem into a non-event, allowing you to stay calm and in control.

At Paragon Dive Store, we believe that safety is the foundation of every great dive. Your SDI, TDI, or SSI training gave you the essential skills, but now it's time to augment those skills with the right tools. Think of these items as your personal "plan B"—gear you hope you never need, but will be profoundly grateful to have if you do. Here are five essential pieces of safety equipment you should consider adding to your scuba kit.

1. A Delayed Surface Marker Buoy (DSMB) and Reel/Spool

If you only add one item from this list, make it this one. A DSMB, often called a "safety sausage," is an inflatable tube that you deploy from depth just before you ascend. It rockets to the surface, unfurling to stand tall and alert boat traffic and your surface support that divers are ascending in that location.


Why It's Essential:

  • Visibility: It makes you highly visible to the dive boat, especially in choppy seas or strong currents where a little head bobbing on the surface can be nearly impossible to spot. For a Tucson diver traveling to the busy waters of California or Mexico, this is non-negotiable.
  • Ascent Reference: It provides a visual reference line for you and your buddy to maintain a slow, controlled ascent rate, which is critical for preventing decompression sickness.
  • Drift Diving: On a drift dive, you often surface far from where you entered. A DSMB is the universal sign to the boat captain: "We're here, we're okay, come pick us up."

What to Look For:

  • DSMB Type: Look for a "closed-cell" or "semi-closed" buoy with an overpressure relief valve (OPV). This allows you to inflate it easily at depth and ensures it won't rupture as the air inside expands during ascent.
  • Reel vs. Spool: The DSMB is connected to a line. A spool is a simple, compact donut-shaped device best suited for deploying from a stationary safety stop. A reel has a handle and winding mechanism, making it easier to manage in a current or if you need to ascend from deeper depths. For most recreational divers, a finger spool with 100ft/30m of line is a perfect start.
  • Color: Bright orange is the standard for "all okay," while yellow is often reserved for emergencies or to signal a specific need to the surface crew.

2. A Reliable Cutting Device

Entanglement is a risk every diver should be prepared for. Discarded fishing line (monofilament), boat anchor lines, or thick kelp can easily snag a piece of gear. Panicking and twisting only makes it worse. A reliable cutting tool allows you to solve the problem calmly and efficiently.

Why It's Essential:

  • Self-Rescue: It allows you to free yourself or your buddy from entanglement without a struggle, conserving air and preventing panic.
  • Versatility: Beyond fishing line, it can be useful for a variety of minor tasks that might arise on a dive.

What to Look For:

You have a few options, each with pros and cons:

  • Traditional Dive Knife: Great for heavy-duty cutting and prying. Look for a blunt or tanto tip for safety and a serrated edge for sawing through rope. The downside is they are bulkier and require some maintenance to prevent rust.
  • Shears / Trauma Shears: Incredibly effective at cutting through line, webbing, and even old wire. They are often more effective than a knife on thin, tough monofilament. Many divers now prefer compact shears stored in a BCD pocket.
  • Line Cutter: A small, protected blade housed in a plastic handle. These are extremely safe, compact, and designed specifically for slicing through fishing line and webbing with a simple pull. They are an excellent, low-profile choice.

No matter your choice, ensure it's made from marine-grade stainless steel or titanium and is stored where you can easily reach it with either hand.

3. A Primary and a Backup Dive Light

"But I don't do night dives!" is a common refrain. It doesn't matter. A dive light is a fundamental piece of safety and communication gear on every single dive.

Why It's Essential:

  • Communication: A light beam is the best way to get your buddy's attention underwater, especially from a distance. You can signal "okay," point out marine life, or indicate a problem.
  • Exploring Overhangs & Wrecks: A light lets you peer into crevices, under ledges, or inside wrecks, revealing the shy creatures that hide from the daylight. It brings the whole dive site to life.
  • Restoring Color: As you descend, water filters out the warmer colors of the spectrum. At 30 feet, reds are already gone. Shining a light on a coral or fish restores its true, vibrant colors.
  • Emergency Backup: If a dive unexpectedly goes long and the sun starts to set, or if you find yourself in an unplanned overhead environment, a light is your lifeline. This is why having two is critical—a powerful primary light and a smaller, reliable backup stored in a pocket.

What to Look For:

  • Primary Light: Look for a robust light with at least 800-1000 lumens, a rechargeable battery, and a beam angle that suits your diving (a narrow beam for signaling, a wider one for illuminating a scene).
  • Backup Light: Should be compact, durable, and have a long burn time with simple, reliable operation. Many divers use non-rechargeable lithium batteries in their backup lights as they hold a charge for years.

4. An Audible Surface Signaling Device

You've surfaced, but the boat is farther away than you thought, and the wind is blowing your shouts away. How do you get their attention? Visual signals are great, but sound travels in ways light can't.

Why It's Essential:

  • Cutting Through Noise: In windy conditions or with a boat engine running, a high-pitched whistle can cut through the ambient noise far more effectively than the human voice.
  • Low Visibility: In fog or at dusk, when a visual signal might be missed, an audible one can be the key to being located.

What to Look For:

  • Pea-less Whistle: The classic ball-style whistle can fail when wet. A pea-less design, like those used by boaters and rescue professionals, works every time. They are inexpensive and can be easily clipped to your BCD.
  • Air-Powered Horn: For an upgrade, consider a device like a Dive Alert Plus. It connects to your low-pressure inflator hose and uses a tiny amount of air from your tank to blast an incredibly loud horn on the surface. It's an unmissable signal.
