ULTRA-FLAT PROFILE. SHIELDED AGAINST DEBRIS EXPOSURE.
The P03 Series in Shield configuration extends the ultra-flat relief platform for buoyancy and inflatable systems built around the P03 interface. Shield Technology adds passive debris protection where external contamination exposure is more demanding. A protected ultra-flat relief platform shaped for streamlined integration and reduced snag exposure.

ITALIAN ENGINEERING.
PREDICTABLE CONTROL.
Each HYDPRO device is engineered and manufactured in Italy: one chain from raw material to release. Polymer families are selected for constant immersion, precision-drawn brass runs on in-house CNC lines, and every device leaves built, tested, and signed off under one roof.
Built to integrate. True to your setup.
Whatever the field runs, HYDPRO builds to it natively: every established mount standard, thread, and host geometry, covered from the factory. Your setup stays as it is, integration stays clean, and the response repeats: the same command, the same result, on every dive.
Proven by divers. Refined by decades.
Four decades in the water stand behind the current generation. What wears, what binds, what drifts out of tune comes back from real dives to the bench, and the next revision answers it. Control you can feel, refined one generation at a time.
