Emergency Air Systems


The solution to preventing injury from a failed surface air supply while diving is simple but it costs money — carry an accessory emergency air source and regulator. The money so spent on this life saver may well be your best investment ever!

A suitable emergency air source converts a panic ascent into a leisurely trip to the surface. Compared to the overall cost of the diving, boat and other equipment, the cost is relatively small.

Please ensure your accessory air source has a scuba cylinder of the appropriate size for the maximum depth you're diving to. You should plan to have enough air for around 15 minutes of breathing on the ascent with a decompression stop if necessary. Smaller all-in-one air regulators generally do not contain enough gas for a controlled ascent, although they are definitely far better than no spare air at all.

The Scuba Doctor recommends a triple-redundant air supply system should be used while hookah diving. The primary air supply is a low pressure (LP) hookah compressor. The secondary is the diver carried bailout or emergency air system. Finally, in an emergency requiring additional time for diver extraction, there should be a scuba cylinder topside, suitably configured so that it can be used to provide air to the hookah diver.

Please read Introduction to Hookah Diving for more information about things you need to consider with a hookah diving setup.



PADI Wreck Diver

PADI Wreck Diver

Whether purpose-sunk as an artificial reef for scuba divers, or lost as the result of an accident, wrecks are fascinating windows to the past. Ships, airplanes and even cars are fascinating to explore and usually teem with aquatic life. Each wreck dive offers a chance for discovery, potentially unlocking a mystery or spying something others have missed. The PADI Wreck Diver Specialty course is popular because it offers rewarding adventures while observing responsible wreck diving practices.

Your training starts by reviewing guidelines for researching and respecting wrecks. You'll also learn:

  • Safety considerations for navigating and exploring wrecks.
  • Surveying and mapping a wreck.
  • Using penetration lines and reels to guide exploration.
  • Techniques to avoid kicking up silt or disturbing the wreck and its inhabitants.

Equipment

It's best to use your own scuba equipment, including a dive computer, plus a dive light to see the wreck, a slate and underwater compass for mapping and navigation. Your PADI Instructor can help you find the equipment that is appropriate for local wreck Diving.

Personal Equipment — You'll need to provide your own bathing suit and towel. For your personal hygiene and comfort, there are some things that we simply choose not to provide you with, and this is more out of concern for your health and well-being than anything else. These include:

  • Snorkel — Risk of orally transmitted diseases
  • Mask — To prevent masks fogging, divers spit in their masks. Would you like to put on your face something that someone else has recently spat in?
  • Gloves — Dermatitis
  • Dive Boots — Tinea is a nasty fungal bug that loves to jump from one person to another
  • Fins — Complete your own snorkelling kit

If you don't already have them, you can buy these items in our dive shop online or in-store. Our experienced dive shop staff can help you with the right equipment choices.

Rental Equipment — Rental gear is not included in the price. The Scuba Doctor has high-quality BCDs, Regulators with Dive Computers, Scuba Cylinders, Wetsuits and Weight Belts available for hire. See Scuba Equipment Rental for details.
