This post comes to you from the very much unmentioned subject, The Science of Diving. Now before you run to the hills after the merest hint of the S-word, remember the friendly folks at GPS are here to sooth your fears & generally want to help…….a bit! Today we’re going to be chatting about our [...]

When I was but a pup of a scuba-doo, I was given a great way of remember all of the gas law’s pertinent to diving as covered in the Science of Diving, often referred to by newbie Divemaster trainees as “SoD’s Laws”. The “cheat sheet” to help you remember the laws is based around each [...]

In our previous post we looked at how we could increase our time underwater by increasing our buoyancy skills, leading to less efforts & lower Surface breathing Rates (SBR). Of course, some may say you can always put a bagger tank on your back. You’ll most definitely need Perfect Buoyancy if you’re continuously changing tank [...]

This year’s International Training Director conference for SSI was held in Thailand, shortly after its conclusion, all of the SSI Instructor Trainers & Certifiers from the region were invited to attend our annual update at a rather swish conference facility on the Thai island of Phuket. I was delighted to hear the statistics of this [...]

When I was a child Vampires & Werewolves were the scary things that came out at night, in modern times they seem to have turned in teenage romantics with an apparent affinity for anaemic chicks, luckily for us we still have real nocturnal wonders to fire the imagination; those of or pertaining to the night. [...]

While maxing & relaxing with Go Pro SSI’s shiny new photographer Nick Shallcross, the conversation turned to our previous post “Abbrvs.” & the promise of more diving abbreviations. This post looks at the professional level Abbrvs. Dive Guide’s are the first level of professional trainees.  Abbrv’d to DG, their role in the diving industry is [...]

Sweet lordy-lord it’s Science of Diving  (SoD) o’clock again! The way I like to teach the SoD is taking all the technical information given by the manual & putting into practical application. We can use all the equations we want with all the measurements of depth, weight & volume given to us but sometimes we [...]

Building on the previous posts in our Science of Diving category I was recently presented with a Divemaster candidate stumped on a question in the SoD exam. Divers new & old can sometimes get lost in the nomenclature of diving & when divers go on about diving “the slack”, they’re often referring to the tide. [...]

Building on my previous blog concerning the Science of Diving, I’ve asked to expand on some of the subjects found in the program; of course I’m not handing out an answer key, just helping to clarify a few things. Section five of the program; The Aquatic Environment contains many topics including Scuba Oeanography, Taxonomy & [...]

The Physics section of the SSI Science of Diving (SoD) Specialty contains many subjects which truly fulfill SSI’s Diver Diamond philosophy of proper knowledge; the principles of physics, measurements & conversions, gases related to diving & amongst other subjects, gas laws. Physics is defined as; the branch of science concerned with the properties of matter [...]
