Sidemount Diver
I started sidemount diving over 10 years ago as part of my initial tech and deco training. Since then I’ve done thousands of sidemount dives and trained divers and instructors on this gear configuration. I am a big fan of sidemount diving and most of my cave diving is in sidemount. I generally prefer it over other configurations. Sidemount offers true cylinder independence, a low profile, and modularity.
There are many sidemount systems and methodologies. It’s crucial to develop solid foundational skills in sidemount before introducing it into cave or deco environments. A structured sidemount course is the best time value for developing those skills.
Benefits of sidemount:
- Cylinder Independence – no chance of isolation manifold failure because there isn’t one.
- Ease of Entry- You can enter that water with 0 cylinders.
- Shorter Profile – Easier access to passages that are wider than they are tall.
Drawbacks of sidemount:
- Gas Management – You must swap regulators regularly to keep pressures balanced.
- Width – Sidemount is harder to fit in passages that are narrower than they are tall (like shipwreck doors).
- Paradox of Choice – Because of the customization available some divers choose methods resulting in lots of drag and inefficiency.
Sidemount Diving vs. Diving Sidemount
Sidemount Diving is using sidemount where it’s required – like small passages or entrances which require rappelling. Diving sidemount is using the configuration in areas where doubles could also be used. Sidemount diving is much less common. We rarely need to use the sidemount configuration, but the benefits of sidemount and comfort often encourage people to dive sidemount exclusively.
Can you sidemount off a boat?
Absolutely! I’ve done this many, many times. It is, objectively, less efficient than using doubles, especially for boats in South Florida. Gearing up takes longer in sidemount than doubles and ladders are not typically wide enough to easily accommodate “widemount” but there are techniques and procedures we can use to make it easier to accomplish.
