Equivalent Diving Qualifications from Different Agencies

8 December 2016
There are many different bodies around the world which award diving qualifications. This table gives a rough guide to equivalent qualifications. It is only a guide though: the qualifications are not exactly equivalent. Please contact your chosen diving agency for their definitive crossover requirements.

The maximum depth guides are all on air. Some grades can go deeper than stated with additional training. Any questions? Get in touch. For instructor grades see below.

Hello,
I am commercial surface supply diver - hse level III (30m), with at least 150 hours dive time. I have read that this level is na equivalent to PADI Rescue Diver, so l could just apply for PADI divemaster directly, is it so? How to achieve such a crossover administratively, please? Via. school/club or PADI association?

, 14 November 2016

Do you also have the HSE SCUBA Diver qualification? We think you would need to be scuba qualified before progressing to the PADI divemaster course - check with your nearest PADI school. To get PADI qualified you need to take the next course up - so you would need to take a PADI divemaster course with a PADI instructor.

Hi there,
I am looking at doing a Divemaster course or equivalent (Dive Control Specialist with SSI), with the aim to work in Australia following an internship. Is there any benefit or loss of going with Padi or SSI on job opportunities? I currently have offers with both PADI and SSI.
Thanks in advance,

, 10 October 2016

Hi Adrian, with SSI you have to be affiliated to a SSI dive shop whereas with PADI you are more independent. In Australia, though, there are lots of SSI shops so there is no disadvantage in choosing SSI. Good luck.

Hi, my husband and I are looking to do a beginner diver course as we want to be able to try out (guided) diving on our honeymoon in the Maldives. We were thinking of starting eith the PADI Scuba Diver course but have also been offered a FEDAS course by our local dive centre (we live in Spain) who assure us that it is a more thorough course than the Scuba Diver and that it is internationally recognised. Do you know anymore about this organisation, have any recommendations regarding which course would be better and whether or not FEDAS is internationally recognised?
, 17 August 2016

Hi Anna
A FEDAS course is more thorough than a PADI Open Water course, and you will be a better diver at the end of it. It is affiliated to CMAS which is internationally recognised. So even if FEDAS is little known the CMAS equivalent will be recognised. Enjoy your honeymoon!

PADI Open water is rated to 40m as an Open Water Scuba Qualification, however most companies will only let you dive to 18 as that was your teaching limit in training.
PADI OWSI and MSDT are essentially the same and not one above the other. Only difference is a MSDT can teach 4 extra courses AND has paid PADI an extra 45 USD. I am OWSI and can teach 8 but refuse to pay just to change 4 letters.

Hi Bev
There isn't an equivalent nowadays as Novice I doesn't include any open water dives.

, 30 March 2016

Hi Gabi
For a PADI Instructor you need to be a PADI Divemaster who has been a certified diver for 6 months, taken an Emergency First Response course in the last two years and logged 100 dives.1 For a CMAS instructor you need to be a CMAS 3 star diver and possess a first aid and oxygen administration certificate. You also need to have taken a Rescue Diver Training Programme and have done at least one hundred dives including night dives, limited visibility dives, deeper dives, drift dives, dives in colder water and navigation dives.2 Good luck with whichever route you choose.

The overview contain some wrong information concerning NAUI. All NAUI recreational courses (Scuba Diver, Adv. Scuba Diver and Master Scuba Diver) contain rescue parts. Rescue Diver and adv. Rescue Diver are specialties. An instructor is allowed to conduct all recreational courses and specialties comparable with a CMAS 3* instructor, instructor trainer is allowed to conduct scuba leaders like divemaster and instructors. Adv. Scuba Diver max. 40 mtr. Prerequisites for a divemaster are NAUI Master Scuba Diver and NAUI Rescue Diver. Recognition of prior learning my be applied. Maybe useful for adjusting some information.

We'll update the site. Be aware though that several agencies in the table include rescue as standard - we err on the side of caution in our table. BSAC, for example, require someone has a NAUI rescue speciality before a NAUI qualification can be considered equivalent to a BSAC Sports Diver.

Is there any PADI SCUBA certification recognized by IMCA to do DMT course? Which level if any?
, 24 November 2015

IMCA stands for International Marine Contractors Association and DMT for Diver Medic Technician. The DMT course is for surface cover team members, who are not diving, to be trained in advanced first aid. To gain the IMCA DMT certification as an offshore diver, you must hold an IMCA qualification (or equivalent) in offshore diving. The equivalent qualifications are for commercial divers, so no PADI courses would be suitable.
There are also DAN Recreational Diver Medic Technician courses run for recreational divers, but these are not accredited by the International Marine Contractors Association. To participate in this course you must have the equivalent (or higher) of a rescue diver certification.

Hi Theresa
You are probably best contacting a CMAS dive centre to check their requirements. Normally you would need the equivalent of CMAS 2 star + Oxygen Administration, Rescue Diver and 50 logged dives including night, limited visibility, dives deeper than 30 m, drift dives, cold water and navigation. Which may mean the SSI Diver Control Specialist level as well as the specialist dives.

En bref, je voudrai leur obtenir l'équivalence de leur certification PADI en un autre brevet CMAS, combien cela me couterait il et comment y procéder?
(Which translates as "Well, I'm OWSI PADI Instructor and certify my students by providing PADI certification, I sometimes meet some requests from some of my students wishing to obtain the CMAS equivalence and also the PADI course and I'm currently looking how to make it possible.
In short , I want them to get the equivalence of their PADI certification in another patent CMAS , how much it cost me and how to get them?")

Hi Adil
You can't get an equivalent CMAS card for a PADI qualification. Your students would have to do an extra course with CMAS. Which level they could go in at is defined in the CMAS - PADI agreement. Other agencies though, like BSAC, do issue CMAS cards.

1) Different between dive tech. and dive master
2) Which among them is the best to know or study

, 18 June 2015

Not sure what you mean by dive tech. Which to study depends somewhat on where you will be diving. With a program like BSAC you get a more thorough grounding than with a PADI Open Water course, but it takes longer. Find out what is available in your area, contact the dive shops and make your choice.

I have many years of diving experience with HSE part 1 11, Military advanced diver from Royal Engineers, I have dived and worked all over the world and yet to convert to PADI. It seems all this experience and qualification has no transferable meaning.
, 25 May 2015

Hello Mark
Many dive shops do recognise HSE. BSAC clubs, for example, recognise HSE part 1 as equivalent to BSAC Sports Diver. If you joined BSAC you could apply for an 'Equivalency Card' from BSAC HQ. This would be recognised by PADI dive centres even if your HSE qualification wasn't. (Although PADI shops should recognise your HSE qualification as equivalent to Rescue Diver.)

I hold a UK HSE Part one from 1988 and an IMCA air diving supervisors qualification from 1993. How best would I prepare papers for holiday diving
, 11 May 2015

Hi David
The best thing to do is to contact dive centres in the area in which you are planning to dive and ask what they need. Your recent diving experience is often more important than which diving agency you qualified with.

Hi Shyam, you can't just transfert to PADI - you always have to do one of their courses. In your case a PADI Instructor Development Course would be appropriate.

Is there a special certificate for a handicapped / disabled diver?
, 24 April 2014

As far as I'm aware there isn't a special certificate for disabled divers, but we'll ask on our social media pages and in our next newsletter to see if our readers know of any. You might be interested in an article by Dave Thompson on learning to dive as a tetraplegic which we published in issue 122 of SCUBA News. Dave qualified as a PADI Open Water Scuba Diver.

Hi
I'm a qualified to HSE scuba and Police Surface supplied as I am a Police diver. I am due to go on my Honeymoon and wish to take part in recreational diving. My partner is going to do a PADI course. I was wondering how well recognised my qualification is. Would it be recognised abroad easily. What would it equate to as a PADI qualification and how easy would it be for me to get PADI qualifications with the qualifications I already have. Thanks
, 10 April 2014

HSE Scuba equates to BSAC Sports Diver or PADI Rescue Diver. You need to contact the dive centre you will be using to confirm that they will understand your qualification. There should be no problem converting to a PADI qualification - but you will have to do one of their courses. Anyone else had experience of using an HSE qualification outside Britain?

A NAUI Master SCUBA Diver is equivalent to a PADI Rescue Diver. So you would be qualifed to take the PADI Divemaster course.

Certified with US Navy Diver Certification - extensive military certification. Since I dive mostly in warm salt water, how do I convert to PADI without going through the entire PADI certification process?
, 26 February 2014

You don't need to do the entire process but will need to do one course, for example the rescue diver. PADI will accept your qualifications as a pre-requisite for the course, but will still insist you take it before giving you a PADI certification card.

It appears that Naui Master diver and SSI Master diver are in the incorrect order. I believe neither of these are professional qualifications.
Naui master diver may be accepted as PADI rescue if the rescue components are taught in that course. SSI dive controller and PADI Dive master are equivalant. Can you confirm please?

Thanks for pointing that out. We've moved them to a more appropriate position.

The listings for SSI don't include the instructor levels and the recreation diver levels are little off. After OW is specialty diver 12 dives and 2 specialties, then AOW diver 24 dives and 4 specialties, then Master Diver AOW plus Stress Rescue Diver and 50 dives. The pro levels can be found on divessi.com to add to your table.
