SIMPLY EXPLANATION TO BALANCED AND UNBALANCED 2ND STAGES

When it comes to second stage regulators, understanding the distinction between balanced and unbalanced models is vital for divers. The second stage regulator relies on a spring to keep the valve closed, but the key difference lies in the forces acting on either side of the spring.

Unbalanced second stages operate with unequal forces on each side of the spring, which can impact breathing ease, especially when diving deeper or breathing hard. Conversely, balanced second stages, exemplified by the Aquatec RG-3100S, channel some of the intermediate pressure to one side of the spring. This engineering refinement ensures smoother and more effortless breathing, making it particularly advantageous for demanding dives or deeper explorations. By grasping this essential difference, divers can make informed choices that enhance their underwater experiences.
