Hi AdilYou can't get an equivalent CMAS card for a PADI qualification. Your students would have to do an extracourse with CMAS. Which level they could go in at is defined in the CMAS - PADI agreement. Otheragencies though, like BSAC, do issue CMAS cards.Jill Studholme, SCUBA Travel

Menekpughi Muele Lord , 18 June 2015(5*)

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 ittakes longer. Find out what is available in your area, contact the dive shops and make your choice.SCUBA Travel

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 andqualification has no transferable meaning.Mark Fender , 25 May 2015

(5*)

Hello MarkMany dive shops do recognise HSE. BSAC clubs, for example, recognise HSE part 1 as equivalent toBSAC Sports Diver. If you joined BSAC you could apply for an 'Equivalency Card' from BSAC HQ. Thiswould be recognised by PADI dive centres even if your HSE qualification wasn't. (Although PADI shopsshould recognise your HSE qualification as equivalent to Rescue Diver.)Jill Studholme, SCUBA Travel

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

Hi DavidThe best thing to do is to contact dive centres in the area in which you are planning to dive and ask whatthey need. Your recent diving experience is often more important than which diving agency you qualifiedwith.Jill Studholme, SCUBA Travel

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

(4*)

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

A NAUI Master SCUBA Diver is equivalent to a PADI Rescue Diver. So you would be qualifed to take thePADI Divemaster course.Jill Studholme, SCUBA Travel

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

(5*)

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

Where is PSAI Advanced Oper Water Diver?Greg, 27 January 2014

(5*)

I'm not sure about where exactly to place PSAI Advanced Open Water Diver - looking at what's involved Ishould think CMAS 2 star. I'll contact the PSAI though, and see what they say.Jill Studholme, SCUBA Travel

It appears that Naui Master diver and SSI Master diver are in the incorrect order. I believe neither of theseare professional qualifications.Naui master diver may be accepted as PADI rescue if the rescue components are taught in that course.SSI dive controler and PADI Dive master are equivelant. Can you confirm please?12 November 2013
