Sidemount versus Backmount – a constant debate

An increasing proportion of divers are making the transition from recreational to technical diving for a variety of reasons, whether it be to go deeper, to stay down longer, to enter caves, or to dive bucket list wrecks. We all have our own individual diving aspirations and reasons why we love being underwater, so when it comes to choosing equipment, why should it be any different? It is all about personal preference.

People often ask me, what is the secret to relaxed and comfortable scuba diving? My answer is always the same – it has to be using the most suitable equipment for your specific dive that meets your individual needs and requirements. This is especially true when it comes to technical diving, as with increasing equipment load and task loading it becomes all the more important to ensure that you are only carrying necessary equipment which is streamlined and you are confident in using.

I dive backmount, sidemount, multistage and CCR configurations; of course, I make it no secret that sidemount is my preference, whether I’m in caves or open water. For me, it’s about taking the weight off my back in any environment. For some, having the weight on their back causes no issues, so then you have to decide what works for you, both in and out of the water in different environments.

This is where training comes in. At the end of the day there’s no substitute for experience – both an instructor’s and your own. By all means talk to people, follow forums, but ultimately there’s no vetting process for who can make comment, so whose opinion can you really trust? The obvious answer is you have to make your own opinion and the best way to do this is to give the equipment a try, but under the supervision of an experienced and reputable instructor. Most full-time technical instructors will have spent 1000s of hours underwater and many of these will have been spent perfecting their equipment, so why not make use of that experience? Skip the awkward errors and time spent analysing how the harness should fit, where the weights should go, what length regulator hoses, which D-rings to use and where – Just skip to the good bit of diving and deciding if you like how something feels. Ultimately, diving is all about feeling relaxed, not stressful or uncomfortable.

So, what’s the right equipment for the right situation? Carrying excess equipment for a dive, eg. 6 cylinders for a 1 hr dive at 10m, is just adding extra stress and strain for no reason. However, the big debate comes in when discussing sidemount outside of cave diving. People still view sidemount as just a tool to squeeze through restrictions by removing cylinders, but sidemount has a lot more to offer than this. When it comes to diving safely in open water, especially  at depths or overhead environments, it’s important to access your valves easily in the event of a gas problem. Some people struggle to access their valves in a twinset, whereas in sidemount, valves are always easily accessible and visible. Taking weight off your back and carrying cylinders separately on the surface is an advantage for those who suffer with back pain or struggle to carry weight. Conversely, if you have no physical issues, then backmount could be right for you. Ultimately, it’s about approaching the decision with an open-mind and recognising that both configurations will give you redundancy – it’s just about what you feel best and most confident in.

There has been much discussion around the difficulties of using sidemount on a boat or effectively staging multiple cylinders for deep dives, but it has to be said that these issues apply equally to backmount and ultimately it just comes down to training from an experienced instructor. Open water sidemount is the relatively new kid on the block in comparison to twinset diving, so unfortunately people are still experimenting, and as a result, getting it wrong. My experience has been that although most boats are fitted out with backmount divers in mind, a well-trained sidemount diver has much greater flexibility towards kitting up, i.e. sitting on a bench, standing up, kneeling on the dive deck, straddling the tube of a RHIB or donning/doffing in the water. There’s no denying the fact that there are pros and cons for each configuration, but it really comes down to how you feel in the water, and with adequate training you’ll learn how to make your life easier and overcome any issues. It’s all about technique, and with the right technique even the smaller, more petite divers, can readily handle multiple cylinders in a variety of situations.

Overall, if you are considering that transition from single cylinder to dual cylinders and perhaps beyond, my ultimate piece of advice would be, don’t listen to all of the talk and the hype about different configurations, but instead go out and give them a try yourself. Spend your time/research finding a reputable instructor who can give you the best taste of the different equipment – you’ll soon know what suits you best and you’ll love your diving all the more for it!

Garry, known to many as ‘Sidemount Bob’ or ‘Chewie’, is fascinated by the underwater world and is equally happy being mesmerized by the gracefulness and beauty of marine life as he is with the eerie silence of the deep and caves. Over the last 18 years, spending most of his time underwater, Garry figured that becoming an instructor and passing on his knowledge would be time well spent, and so he did just that. Having qualifications in all of the major training agencies in OC, SCR and CCR, his intrigue into various kit and configurations led him to research the theory and practicalities into Sidemount diving for which he is globally reputed. It’s in Garry’s nature to push himself to his limits, clearly evident in his cave diving explorations. Presenting at primary and secondary schools, dive centres and national dive shows, he’s a director of training agency RAID UK & Malta, an Instructor Trainer, recreational, technical and cave diving instructor, and a key member of the “Apeks Cave Exploration” and “Apeks Tek Testing” teams, and has been exploring newly discovered cenotes in the Yucatan district, Mexico as well as mines and caves in the UK and Spain. For several years, Garry has offered Sidemount training in single and/or twin cylinder configuration as well as multiple cylinder technical diver training.
