When the diver carries several diving cylinders, especially those made of [[steel]], lack of [[buoyancy]] can be a problem, particularly at the start of a dive when they are all full, and the variation of buoyancy during the dive as the gas is used can require high-capacity buoyancy compensators to allow the diver to effectively maintain neutral buoyancy throughout the dive.{{<ref>{{cite journal |doi=10.3389/fbioe.2020.570657 |doi-access=free |title=Front Crawl is More Efficient and Has Smaller Active Drag Than Backstroke Swimming: Kinematic and Kinetic Comparison Between the Two Techniques at the Same Swimming Speeds |date=2020 |last1=Gonjo |first1=Tomohiro |last2=Narita |first2=Kenzo |last3=McCabe |first3=Carla |last4=Fernandes |first4=Ricardo J. |last5=Vilas-Boas |first5=João Paulo |last6=Takagi |first6=Hideki |last7=Sanders |first7=Ross |journal=Frontiers in Bioengineering and Biotechnology |volume=8 |pmid=33072727 |pmc=7543982 }}</ref><ref>{{cite journal |url=https://mjssm.me/?sekcija=abstract&artid=294 | title=Comparison of the Active Drag and Passive Drag Coefficients at the same Swimming Speed Through Experimental Methods | journal=Montenegrin Journal of Sports Science and Medicine | volume=14 | issue=1 | pages=81–86 | last1=Lopes | first1=Tiago J. | last2=Sampaio | first2=Tatiana | last3=Pinto | first3=Mafalda P. | last4=Oliveira | first4=João P. | last5=Marinho | first5=Daniel A. | last6=Morais | first6=Jorge E. }}</ref>}}

A large number of cylinders, hoses and fittings passing through the water tends to increase [[hydrodynamic]] [[Drag (physics)|drag]], reducing swimming efficiency.{{citation needed|date=December 2016}}
