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 [...]

Many divers; both new & experienced, wish for one thing above all others whilst diving. More time underwater. Limiting factors in diving come in one of two basic types, time & gas supply. Fortunately for us, we live in a time where extending our limits beneath the surface has never been easier. In this blog [...]

Every human being has the capacity for self-directed behaviour change within them, whether its change with their lifestyle or the choices made about Scuba training. Behaviours are influenced by both personal & environmental factors in everyday life, with determinates of social, physical, psychological & economic nature affecting our decision making every day, diving is no [...]

Straight off the bat I think its fair I should point out that the concept of new Instructors completing Internship style programs is an excellent idea. I believe anyone new to a profession; Scuba Instruction or any other, who admits they would benefit from supervised experience before heading out into the blue under their own [...]

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.

When I first embarked on the adventure of Scuba diving, during my SSI Open Water Diver course I was first taught how to snorkel properly. Among the skills shown to me were how to clear my snorkel & mask & also how to descend correctly both head first with a duck-dive & a feet first [...]

In the world of diving we love having our own little language; our acronyms & abbreviations, its makes us feels special. I have noticed myself using them without shame in some of my blog posts without really explaining them all, silly me! The acronym that get bandied about the most with non-dives & a shocking [...]

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 [...]
