Performance:

The air cell on the Hydro D is horseshoe-shaped, which enables the tank to be positioned closer to the body. Removable bungee straps rein in the air cell at depth to minimize hydro drag, and three remote exhaust valves allowed test divers to easily control their buoyancy in all diving positions. Female test divers liked the responsive and supercompact power inflator that fits neatly into smaller hands, but found the BC a bit “long waisted.” On the other hand, the female test divers found the cargo pockets functional and accessible, while male divers had trouble getting their hands into them. All test divers agreed the Hydro D was comfortable and very stable at depth. Like on the Alpha, the weight-ditch handles are positioned a ways back from centerline. But once grasped, they ditch without problem. Bonus: The Hydro D’s horseshoe wing can be removed for easy replacement.

Bottom Line:

The Hydro D offers lots of adjustment, is comfortable and behaves well underwater. It also carries 2-and-a-half pounds of inherent buoyancy, among the highest of this year’s tested BCs.
