Test divers agreed that the Hydro D was comfortable and stable at depth, and the double-locking weight ditch handles dropped the weights without problem. They also liked the responsive, compact power inflator that has a convenient pull-dump feature. There's a lot to like in this BC!
It offers a lot of adjustment to customize your fit, and is amazingly comfortable and stable underwater. Constructed with rugged 840 Denier nylon with its technical style inner air-cell and protective, three-dimensional spandex gusseted outer shell, HydroD offers the kind of unrestricted mobility that a traditional jacket-style BCD cannot. Its harness system can be easily adjusted to provide a personalized fit. Supple, amply padded backpack with 3-remote exhaust valves, and a double-locking integrated weight system. Streamline features such as the horseshoe shaped wing (allows the tank to be positioned closer to the body) and 2 removable bungee cords (stop unwanted drag when partially inflated underwater) are hydrodynamic and translates into less energy expansion. The padded harness provides ample adjustments for personalized fitting. Removable bungee straps rein in the air cell at depth to minimize hydro drag, and during recent ScubaLab tests, the three remote exhaust valves allowed test divers to easily control their buoyancy in all diving positions.
