Most scuba divers get excited about exploring inside caverns and cave entrances. But, you need to have the skills and knowledge to do it safely.
This section explains how to make four (4) training dives with a PADI Instructor and get certified as a Cavern Diver Specialist - and you can do it in only two (2) days.
Important: The Cavern Diver Specialty certification may count towards the PADI Master Scuba Diver Rating. So, check our PADI® Specialty Courses List for further details on fifty (50+) other specialties (listed from A to Z).
In simple terms, a Specialty Diver is someone with enhanced scuba diving abilities beyond entry level certifications (e.g. Discover Programs, Scuba Diver, Open Water Diver).
Signing up for specialist scuba courses is the ideal path to take if you want to learn new techniques and experience different kinds of underwater exploration.
Furthermore, you will get the best opportunity to acquire superior knowledge and skills in the diving activities that interest you the most because a 'Specialty Instructor' will be supervising the training.
The knowledge and skills that you learn in this course train you for swimming inside large convex overhangs. But, you must stay within the 'natural' light zone so you can make an easy exit from the undersea chamber back into open water.
There are minimum age requirements and maximum depth limits for all the specialties that require scuba training dives in open water.
As a result, before you can enrol in the PADI Cavern Diver Specialty course you will need to be (all):
Important: Even though scuba certifications do not expire, we recommend taking the PADI ReActivate® refresher course if you have been inactive from diving for a while (e.g. longer than six months).
The typical locations where scuba divers can explore caverns are freshwater springs, limestone coastlines, and the walls of volcanic islands (e.g. Barren Island dive sites).
Some divers choose never to make any cave dives. Whereas others can't wait to get certified as Advanced Open Water and sign up for the Cavern Diving Specialty certification course.
Why dive into caverns?
This course is not for beginners. But, if you are looking to improve your dive planning skills you will benefit from the specialised training.
Furthermore, some of the best scuba diving locations around the world will have a hollow crevice or cavity to swim under. Thus, the only way to go inside a dugout safely is to get certified for cavern diving.
Some of the things you can see in the natural light zones of undersea caverns, include:
It is important to understand that the techniques and procedures used when entering and exiting the water for diving into caverns will vary.
Having the knowledge and unique skills to explore distant locations away from the shore is another reason for taking the course.
Do you like swimming with big fish?
In general, it is much easier for divers with a busy schedule to choose the online learning option to start scuba lessons.
Being able to complete the independent study portion of a multiple day course offers you some flexibility and convenience.
As long as you have a computer or a mobile device, you will be able to study the knowledge development portion at your own pace (online or offline).
You need to participate in the instructor-led knowledge development sessions by completing all knowledge reviews from the Cavern Diver student manual.
Of course, you will learn how to enter and exit underwater caverns, chasms, and tunnels in a safe manner while wearing scuba gear (often from a custom-built dive boat).
Besides that, you will also learn about:
Pro Tip: Another section contains information about the Night Diver Specialty course and where to find nocturnal creatures that become active in dark environments.
You need to wear standard scuba gear for the four training dives conducted in open water. Other specialist equipment for cavern diving may also include:
The term 'deep dives' has a different meaning in recreational scuba diving than it does in technical diving.
The deepest dive made for recreational purposes should not be below forty metres (130 feet). Whereas, a professional technical diver can go down to sixty (60) metres (200 feet).
We refer to the US Navy decompression dive tables to answer this question. Divers can only stay at forty seven metres (160 feet) for around five minutes before they need to decompress during the ascent.
The Titanic is resting at a depth of 2,100 fathoms (12,500 feet). Because normal air consumption through a standard tank only lasts about fifteen minutes at 40 metres, scuba diving to the Titanic is impossible.
Fun Fact: The deepest scuba dive ever made is 332.35 metres (1,090 feet) undertaken by Ahmed Gabr in September 2014 in Dahab, the Red Sea. Using open circuit scuba, it took only fifteen (15) minutes to make the descent, but the ascent took thirteen (13) hours and thirty five (35) minutes.
Nonetheless, PADI does consent to a kind of 'solo diving' through the Self-Reliant Diver certification course, which is available in Pattaya, Thailand.
You may have seen divers make 'flying saucer' bubbles ascend from the abyss to the surface. So, what is a divers bubble ring? Our blog article explains the technique for blowing ring bubble circles underwater.
Divers share a common responsibility to protect and conserve nature. As a result, interacting passively with aquatic animals helps to safeguard the habitats of delicate and sensitive sea life.
After cleaning the gear, there are several kinds of activities that divers should avoid doing. They include:
Suppose you don't go diving for more than six months. There is a simple way to refresh the knowledge and skills that you already learned.
After a long period of inactivity, taking the PADI ReActivate® program will help you brush up on the safety procedures and scuba diving fundamentals.
You must be in good physical and mental health and be medically fit for recreational scuba diving. You can review the Diver Medical Participant Questionnaire Online to check whether you need to be evaluated by a physician.
It is not appropriate to ask dive staff (e.g. divemasters, instructors) for medical advice or clearance to go diving. Instead, you can contact the Divers Alert Network (DAN) if you have questions about your medical fitness to dive.
We have qualified instructors and expert dive guides who can teach in several languages, including English, Thai, and Chinese.
The price includes (all):
Important: You will usually be making two (2) scuba training dives in the same day. The PADI flying after diving guidelines say you need to wait a minimum of eighteen (18) hours after the second dive before you go to altitude. Please send an email to our team if you need further information.
Most of the information and advice in this section focuses on deep scuba diving activities which we usually conduct from a boat in Thailand.
Note: The short video presented by PADI highlights what to expect when taking the Cavern Diver Specialty course. It also emphasises some of the protocols and procedures for divers at some of the most dangerous dive sites around the world.
Cavern and cave diving is very popular with almost all divers because of the excitement and exhilaration that going to "out of the way places" can offer.
Even so, the PADI® Cavern Diver course combines really well with several other specialty courses such as, AWARE Shark Conservation, Boat Diver, Delayed Surface Marker Buoy (DSMB) Diver, Multilevel Diver, and Wreck Diver.
