1 Introduction
Some years ago I was talking to a very good friend of mine, a professional and very experienced cave diver, about sidemount diving.
In his broad southern German dialect he exclaimed, very upset, ‘Oh, don’t give me any of this bull… . All of a sudden everybody is an expert. Just because they’ve conducted a few dives with sidemount configuration they think they can tell us how it works. We’ve been doing this for years, but they think they know it all!’
Back then I didn’t follow this up, but later I found out: he was right!
What I mean to say is:
Sidemount diving is not really new. It has just lived in the shadows for a long time or was regarded as a second-rate variation of backmount diving (in the form of stages).
There is indeed very little instructional material on the market, presumably in order not to encourage divers to try an autodidactic approach.
There are a lot of variations and just as many instructors who propagate their own specific system. And when observing the debates on the internet, you can really get the impression that quite a few people, who are professional instructors, rail at everything that differs from their own dogma – probably because they feel their reputation and possibly their existence as a professional instructor might be in jeopardy!
But ideologies often prevent you from seeing the bigger picture. One should look at all the options before making a choice. Everybody has different preferences, and something that is suitable for one person may not be the right thing for another.
And last but not least – if the crazy cave-diving danger seekers have been using sidemount configurations for years and are still alive, it can’t be that bad!
Of course I will elaborate on all these points in the following chapters and hope that it will be as informative as interesting.
However the considerations in this book cannot be final, there are too many possible variations and different training instructors attach more importance to some points than to others. Some things are suitable for all purposes, others specifically for technical diving and so forth, but primarily this book is aimed at beginners of sidemount diving.
2 History of Sidemount Diving
Diving with Sidemount Configuration originated in the 1960s in the United Kingdom.
Cave explorers often faced the problem on their excursions that flooded syphons were not passable by foot. They therefore carried scuba diving equipment with small cylinders in order to dive through these narrow passages. Because most of the exploration trip still took place on dry ground, explorers experimented with very minimalist equipment which would hamper them as little as possible. Cylinders were mounted at the side of the body and attached with a belt to the waist and thigh. That way the equipment could be donned and removed quickly and wasn’t too bulky. The single cylinders were not broader than the body of a person and could be shoved ahead or dragged behind when passing through bottlenecks. The so-called ‘English System’ was born.
In the 1970s US-American Cave explorers applied the system to exploration trips which mainly took place under water which meant that it had to be adapted to the requirements of cave diving.
Attached to the thighs, the cylinders would have hindered paddling hence they were moved further upward, towards the armpits. However, they were still carried at the side of the body due to reasons which we will explain later on. Also, a buoyancy system was needed. Home-made belt systems and improvised buoyancy compensators were constructed, for example the legendary buoyancy compensators based on the Camelbaks® – hydration packs for endurance athletes. These were sewn, glued, or tied on to the belts and de- or inflated via the drinking tube.
Since the 1990s sidemount systems have been mass-produced by manufacturers of diving equipment, and diving with sidemount gear has been made accessible to a broader public. The purchasable systems feature different versions and in this book we will introduce the three basic configurations they are based on.
2.1 Sidemount Diving – Monkey Diving
The term sidemount diving indicates a configuration of equipment where the cylinders are mounted only at the side of the body and not on the back (backmount). Special attachment and buoyancy systems are being used, which show the benefits of this way of diving to its best advantage: freedom of movement, diving in any desired body position, perfect trim, etc.
In Anglo-American usage the term ‘monkey diving’ has become established for diving in sidemount configuration. Diving with laterally mounted cylinders obviously wasn’t regarded as sensible.
It should be noted that there is a conceptual distinction to be made when diving with side mounted cylinders when the main air supply cylinders are mounted on the back:
3 Benefits of Sidemount Diving
Even though sidemount diving has been practised for years by cave and wreck divers and although it bears a lot of benefits, as we will see in the following, it has not yet caught on in recreational diving.
Why has sidemount diving lived in the shadows so far? First of all some of the reasons, why sidemount hasn’t become more popular yet:
First obstacle: lack of instructors
The number of instructors who would offer taster courses in sidemount was low and purchasable equipment, required for beginners was not available. The configuration was developed autodidactically, then improved, but always regarded as a means to an end, mainly for technical divers. For a long time there were no instructors or manufacturers, nobody felt called to make sidemount available for the vast number of recreational divers. Only recently instructors and diving schools have picked up on the subject.
Second obstacle: Change is always scary…
But: Don’t be afraid of change, be afraid of stagnation!
Give it a try! Even if you don’t stick with sidemount you have aquired new skills and broadened your mind! And if you should ever dive backmount with a stage bottle, the insight and the practical experience you have gained with sidemount will be very helpful.
Third obstacle: money, money, money… you might have to spend a
