Dive computers, and the PADI eRDPml™ (electronic planner of multi levels), can analyse and calculate the benefits of 'off-gassing' using multilevel diving techniques and procedures.
This section explains how to extend bottom time on scuba dives by gaining credit for slower nitrogen absorption as you ascend to 'tiered' shallower depths.
Note: The Multilevel Diver Specialty certification may count towards the elite Master Scuba Diver rating. Check the PADI Specialties A to Z list for further details about more than thirty other courses.
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 most because a 'Specialty Instructor' will be supervising the training.
The PADI Multilevel Diver Course emphasises how prudent it is to make stepped ascents to progressively shallower levels throughout the dive. In short, it maximises the time allowed underwater.
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 Multilevel Diver Specialty course you will need to be (all):
Important: Even though PADI scuba certifications do not expire, we recommend reactivating it through a refresher course if you have been away from diving for a while (e.g. longer than six months).
Many years ago, the system used to calculate dive profiles would be like the letter 'U'. In other words, the diver goes from the surface down to the maximum depth and then straight back up to the surface.
Nowadays, most scuba divers will be using a dive computer or watch that analyses their depth - especially during the ascending phase of the dive.
Why is this important?
Usually, making tiered dives means you get more bottom time when you go shallower. So, the new system maximises the duration spent underwater.
The Multilevel Diver Specialty course helps you learn how to use dive computers and other calculator tools (e.g. the eRDPML).
When you know how to plan an extended dive safely, you can tryout the new skills on shipwrecks and deep dives, such as:
Having the knowledge and unique skills to explore deep diving destinations is another reason for taking the multilevel and computer course.
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 student manual.
Of course, you will learn how to enter and exit deeper water in a safe and effective manner while wearing scuba gear (often from a purpose-built dive boat).
Besides that, you will also learn about:
Note: Did you successfully complete the elective Multilevel Dive from the Adventures in Diving course? If so, an instructor may count it as being the first training dive for certification requirements in this specialty course.
You need to be wearing standard scuba gear for the two (2) training dives conducted in open water. Other specialist equipment for multilevel and computer diving that you'll use, may also include:
Note: Using different underwater torches will be useful as the surroundings become darker and if you will be navigating your way through any dangerous structures (e.g. 10 best wreck dives in the world).
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).
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.
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.
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.
We also have a list of blog posts about snorkeling - with other popular watersport tourist attractions at the beach resort of Pattaya.
Note: The short video presented by PADI highlights what to expect in the Multilevel Diver Specialty course and how to get credit for slower nitrogen absorption.
