Can You Scuba Dive Alone?

While scuba diving is typically done with a buddy, some experienced divers do go solo diving. Diving alone can be fun but also comes with risks.

In this comprehensive guide we will cover everything you need to know about scuba diving alone and some tips to follow.

Is it Possible to Go Scuba Diving By Yourself?

Scuba diving solo is possible for experienced divers with the right training, skills, equipment, and precautions in place. However, it is generally recommended to always dive with a buddy. It goes against standard scuba diving safety protocols and is considered high-risk.

Some key factors to consider when solo scuba diving:

  • It is only recommended for very experienced divers with specialized diving certification. It is not for beginners.
  • You take on all responsibility for your own safety when diving alone. There is no buddy to assist in the time of emergencies.
  • Most dive operators prohibit diving alone due to the risks. You may need to find specific diving charters.
  • Your diving limits should be conservative – stay well within training limits and comfort zone.
  • The use of surface marker buoys and redundant air systems is mandatory for added safety.
  • You must have mastered self-rescue techniques and emergency procedures.
  • Specialized equipment like full-face masks may help reduce risks when diving on your own.
  • Only dive at sites you’re very familiar with and with mild conditions.

While it’s possible for experienced divers, it’s generally advised to avoid going solo when you can dive with a partner for added fun and safety. Careful consideration of the risks vs. rewards is needed when planning any dive.

Is Scuba Diving Solo Legal?

There are no universal laws prohibiting solo recreational scuba diving. However, many dive operators, charters, clubs, and organizations don’t advice on going solo and impose buddy policies that require diving in pairs.

This is because it goes against standard safe diving practices taught by major training agencies like PADI and SSI.

Some key legal considerations:

  • There are no federal laws in the USA or internationally that prohibit solo scuba diving.
  • Liability waivers must often be signed by dive operators.
  • Training agencies like PADI discourage solo diving but offer specialty courses on managing risks.
  • Most dive insurance policies exclude cover for solo diving due to the high risks involved.
  • Diving by yourself on shipwrecks, in overhead environments, or in marine reserves may be illegal.
  • Local regulations may restrict or prohibit such dives at some sites, so check ahead.
  • If diving in international waters, the laws of your dive boat’s country of origin generally apply.

While it isn’t outright illegal in most cases, the associated risks mean operators and insurers often prohibit it. Carefully check all policies, waivers, and local rules before planning your dive.

Is it Safe to Go Scuba Diving Alone?

Scuba diving alone introduces significant risks and is considered extremely unsafe by diving experts. It removes your buddy – your primary source of assistance if something goes wrong underwater.

Safety issues to consider when scuba diving alone:

  • No buddy to help in an emergency like a stuck regulator, low air situation, or unconsciousness. You’re completely self-reliant.
  • No one to assist if you get entangled, trapped, lost, or experience equipment issues.
  • No one knows your planned dive profile or where you are if you fail to surface.
  • No one to share air with if your tank runs low or malfunctions.
  • Limited ability to assist your dive buddy if they have an emergency.
  • No one to help remain oriented and monitor time/depth/air levels.
  • No one to offer rescue breaths if you lose consciousness underwater.
  • First aid response times are slower if injured.

While cautious planning, specialized equipment, and training can help reduce risks, any kind of scuba emergency is far more dangerous when being alone.

Most experts advise that the only really safe way to scuba dive is with a competent buddy at your side. Consider alternatives like snorkeling or freediving if you insist on not having a dive partner.

Can You Get Scuba Certified To Dive Alone?

Major recreational scuba training agencies like PADI and SSI do certify or endorse solo sport diving scuba courses. However, instead they call it self reliant diving.

Key points on solo diving certifications:

  • PADI, SSI, and NAUI train buddy diving procedures – not solo skills. Instead you can choose their self reliant training.
  • TDI’s Solo Diver certification course teaches self-reliance skills.
  • IANTD (International Association of Nitrox and Technical Divers) also offers a solo diving certification.
  • Most agencies suggest at least 100 logged dives before attempting a specialty solo diver training.
  • Courses cover hazard avoidance, emergency protocols, redundant gear requirements, and managing dive situations.
  • Successful certification still does not guarantee dive operators will allow you to dive on your own.
  • Annual refresher training may be required to stay certified as a solo diver.

While courses exist, the certification is not a replacement for the vital safety benefits of the standard buddy system. Specialized training aims to reduce, not remove, the substantially elevated risks involved with scuba diving alone.

What Skills & Experience Are Needed to Solo Dive?

Solo diving requires very advanced skills, experience, judgment, and extensive specialized training.

Agencies suggest prerequisites before considering attempting to dive alone:

  • Certification as an autonomous scuba diver at a minimum. Technical diving credentials are preferred.
  • 100+ logged dives with extensive experience in various conditions.
  • Comfort diving to depths of 100+ feet.
  • Excellent buoyancy and trim skills diving unencumbered.
  • Mastered efficient air consumption breathing techniques.
  • Expert at monitoring dive computers/gauges and managing dive profiles.
  • Skilled with navigating by natural references without a guide.
  • Knowledge of appropriate diving equipment and configuration.
  • Regularly conduct safety drills for self-rescue techniques like ditch & recovery.
  • Current first aid, oxygen provider, and CPR training credentials.
  • Experience managing minor equipment malfunctions like free flows.

Diving alone requires an extremely high degree of self-sufficiency and competence, managing dive situations entirely independently. Don’t attempt it until you’ve mastered all standard scuba skills and have hundreds of dives under your belt in a wide variety of conditions.

Even then, it remains a very high risk.

What Equipment is Recommended for Solo Diving?

Specialized scuba gear and redundant backup systems help enhance safety when diving alone:

  • Redundant air sources – independent dual tanks and regulators are mandatory. Pony bottles or spare air systems provide backup air underwater if your primary tank fails.
  • Surface marker buoy (SMB) – deployable buoys with flags signal your position to the surface crew. Allows easy location if you’re in distress.
  • Full face mask – provides integrated 2nd stage regulator and mask in one. Eliminates a failure point between the mask and regulator.
  • Wrist mount dive computer – easy to monitor your dive status without a buddy to cross-check.
  • Audible dive alerts – preset depth and time alerts help keep you oriented without a partner.
  • Cutting device/diver’s tool – allows self-extrication if trapped or tangled in gear.
  • Signal devices – carry backup lights, whistles, strobes, and surface flares to signal for help in case of emergencies.

Having thoroughly practiced using redundant gear configurations during diving certification is key. Streamlining and familiarity with your diving equipment setup avoids trouble handling it independently in an emergency.

What Are Some Tips and Precautions for Diving Alone?

If contemplating a solo dive, experts recommend stringent precautions to reduce the considerable risks:

  • Only dive at sites you’re intimately familiar with in ideal conditions.
  • Use the most conservative dive planning tables and stay well within no-decompression limits.
  • Have a strict turn-around time and begin ascent immediately if issues arise.
  • Always over-prepare equipment by meticulously checking and streamlining it.
  • Carry multiple surface signaling devices – don’t rely just on an SMB.
  • Ensure someone ashore knows your exact dive plan and when to expect your return.
  • Stage emergency oxygen and first aid kit on site for self-administration after diving.
  • Dive only when you are in peak physical and mental condition. Avoid diving when tired or stressed.
  • Abort the dive for any hint of problems – don’t push limits when there is nobody around.
  • Consider whether it is truly necessary vs. rescheduling to dive with a competent partner.

The safest dives are ones you choose to abort before entering the water. Careful assessment of both internal and external conditions is vital to reduce risks when scuba diving by yourself.


Is solo diving considered technical diving?

Solo scuba diving falls under the umbrella of technical diving since it requires specialized training, equipment redundancies, and high experience levels beyond recreational diving limits.

Can I solo dive if I am a certified rescue diver?

The advanced skills taught in rescue diver courses help reduce risks but do not qualify you to dive alone. Specialty diving credentials are still required, along with extensive experience before attempting such a dive.

Is solo cave or wreck diving allowed?

Solo diving in overhead environments like caves or inside wrecks is extremely hazardous and prohibited by most operators, even with proper diving credentials. The confined spaces make self-rescue nearly impossible if anything goes wrong.

Can you freedive alone safely?

Freediving solo has far fewer equipment and decompression risks than scuba diving alone. But you still lack a buddy for emergency assistance. Know your limits and carefully assess conditions before attempting any breath-hold dives without a partner.


While an enticing prospect for some very experienced divers, scuba diving alone significantly increases risks in our already dangerous underwater sport.

Specialized solo training, redundant gear, and conservative profiles can help reduce, but not remove, the inherent hazards of diving alone.

Most experts agree the buddy system still provides the safest and most enjoyable way to scuba dive. Carefully consider your motivations and the risks versus rewards when considering doing a dive on your own.
