If you’re like me, speaking twelve different versions of English never really counts as being multilingual & languages can be a hot topic in the world of diving. Adopting the technique of expanding your credentials in diving is one way that can really help you stand out from the crowd, & an excellent way to [...]

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 [...]

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 [...]

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.

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 [...]

During the SSI Open Water Diver course we introduce the concept of working out Surface Breathing Rates or SBR’s. The amount of gas a diver consumes either at work or rest per minute at surface pressure. Also referred to as Surface Consumption Rates (SCR) & Surface Air Consumption (SAC) Rates, but not always pertaining to [...]

With high season for Koh Tao popping its head up once again, lots of enquiries have been coming my way about SSI Specialty combinations. Following up on the previous post “Threesomes” about the ability to combine up to three SSI Specialty Courses together for the SSI Advanced Open Water Diver rating to reflect the “Training [...]

A Threesome can be a tricky thing to pull off but, luckily enough SSI Instructors are molded from sterner stuff & three is, after all, the magic number! Before you get all weird I’m talking about Specialty Course combinations. Combining Specialty courses is something quite unique to SSI; the belief that you’re not task loading [...]
