The Hydrotank is a high-capacity, lightweight scuba cylinder featuring an internal bladder that acts as a flexible gas container. When paired with the Jetpack system, divers can add or remove water from the cylinder to fine-tune buoyancy. This integrated approach delivers exceptionally stable, neutral buoyancy by using water as your weight.

The bottom of the cylinder includes a robust protective cage that allows Hydrotanks to be stored upright, shields the built-in high-pressure hose, and provides a secure location to add lead weight if needed.
