HYDROTANK

Size: 8L - Raptor Finish

SKU: 18008

Available early 2026.

The Hydrotank is a high-capacity, lightweight scuba cylinder with an internal bladder which acts as a flexible gas container. When used with the Jetpack, the diver can add or remove water from the cylinder to change buoyancy. This is an integral part of the system that provides perfect neutral buoyancy by using water as your weight.

The bottom of the cylinder is equipped with a protective cage to allow the Hyrdotanks to be stored upright, protects the built-in high-pressure hose, and allow you to add lead weight if necessary.

DYNAMIC BUOYANCY CONTROL

The Hydrotank uses water as weight, so it is like having a scuba cylinder that can be made smaller (less buoyant) or larger (more buoyant) while submerged.
