It is with the heaviest of hearts that we bring you sad news. Our Abu Mike passed away Sunday morning in New Zealand. His family were by his side. Mike touched so many peoples' lives in Vanuatu, He will be so sorely missed. He was the first dive operator to believe that Ni-Vanuatu divers...

I recently did some diving on Australia's GBR. First time ever on a dive boat setup for 50 divers or more. Definitely not my style of diving. Max bottom time 40 minutes. Dive 1-2 surface interval only 10 minutes. It seems ive been well spoiled diving in the pacific with max numbers 14 per...

Hey Guys Im just checking to see how you would deal with this scenario. Advanced open water diver 200 plus logged dives and recent dives.who had dived only tropical. Wanted a checkout dive in a 7mm suit. First issue. They had no idea of how to set up their gear.-Literally not a clue. Second...

Hey folks Ive gotten into open sea swimming.Part of this is getting your body as streamlined as possible. my swimming wetsuit is very different from a scuba suit but it got me thinking a bit about scuba suits Mens swim suits have 5mm of rubber in the legs and 2mm round the arms to give extra...

hey folks my lovely wife is a keen diver. What is stopping her is that she has limited lung expansion. This makes diving with a 5mm farmer John suit (10mm through the core) impossible. She literally doesn't have the ability to expand her lungs against the pressure of the suit. Equally she...

Sorry if this is crowing a bit folks but Im actually pretty darn proud of my Family of divers. On our recent dive based holiday we had quite a few qualifications gained. My youngest son at 12 now has his Junior Open water cert Next son at 16 is now an Advanced Open water Diver. Next...

Hey folks I'd like advice from instructors, actual dive ops etc. Ive done all the skills needed to get my Divemaster qualification. Literally I have 2 more dives to lead and Ive passed. So Im looking at what I need to do moving forwards towards a full instructor rating. Im getting conflicting...

Im almost finished my divemaster certification part of which is assisting with DSD dives in the pool and Open water students. The location is tropical so a lot of the time the dress code is bikini or a one piece swimsuit. the gear we use is a standard BCD -one strap over the chest -buckle...

hey folks am I missing something with Padi certification. As an adult you can do DSD dives Scuba Diver certification then/or Open water certification. I noticed that doesn't seem to be an option for kids. What am I missing?

Question for instructors. Lets say an OW student or maybe a DM candidate was working through a question sheet from one of the Dive agencies to pass a test. One question is using the RPD to calculate an end pressure group after some bottom time at a depth. The calculation means the diver is...

Got back Yesterday from doing as much of my Divemaster course as time permitted. I don't really know what to say. Did I work my a## off. Yep. Have I worked my a## off for the past few months. YEP. Did it pay off er um yea you could say that. The written final exam is a two parter. Part one I...

Hey folks one case study has me thinking. Senario is.--drift dive You leading and an instructor is with you. 6 certified "customer" divers One diver uses a lot more air than normal and gets to 500psi after 25 minutes. No issues with air checks etc depth is roughly 24m/80 feet.Low air...

A bit of a spin off from the multiple threads asking what tank size to use. Given the improvements in material quality over the past 40 or so years why are we still sticking with our tanks pressure restricted to 200 bar 3000psi or thereabouts? Are there compressor limitations in play as well as...

Ill preface by saying sorry to ask on here. But Im a long way and expensive toll calls away from where I'm going to do my DM course. Ok one question in the DM manual has me tearing my hair out. its the one that goes- Leading a group on a 40 foot boat. bilge is filling slowly. the cause is...

Specifically when acting in the capacity of Divemaster or instructor do you deliberately overweight yourself ? if so Why? If not Why? By how much if so? im thinking it will be easier to demo BCD use to students if overweighted a couple of KG and offers the ability to "hand off" a kilo...

Hey guys sorry to start a new thread but Ive got questions I need answered. Dive op is 3.5hours flying away and its an expensive toll call to call them I AM doing my PADI Divemaster training starting Late June. I understand the fitness requirements are 1)400m swim 2) 100m "tired" diver tow-...

hey folks My Padi EFR has just expired after 2 years. The LDS has informed me I need to redo the entire course. Padi say I need to do a refresher.Which is true ?

I was lucky enough to get to do a bit of diving in new Caledonia recently. Over there it seems the dive culture is a bit different than elsewhere in the pacific. First thing I noticed was that all tanks are set up with DIN rather than Yoke valves. The next thing I realised was that the CMAS...

The new 787 Dreamliner advertises that the cabin is now pressurised to 6000 feet /1800m rather than the traditional height of 8000feet. I still prefer to stick to a 24 hour no fly after vacation diving but in theory does the "lower" height translate to theoreticaly shorter no fly times?

Folks I will start this post by saying I'm sorry if its old news or I'm asking something that's odviously impossible. Out at the Poor Knights dive site on a surface interval I watched a couple of deep divers prepping for a dive. Given the technology available in this the 21st century why...
