Why it's worth a look

• Effortless breathing with the balanced flow-through piston first stage regulator.
• Dive confidently with reliable performance, featuring five LP and two HP ports for versatility.
• A comfortable fit thanks to the pneumatically-balanced second stage design.
• A durable build with chrome-plated brass and 316-grade stainless steel construction.
• Maintain your gear easily; the titanium demand valve ensures lasting quality and simple care.
• Great value with this Nitrox compatible (up to 40%) regulator set for all your dives.

Before you buy

Match DIN or yoke to the tank valves you use most, and confirm a local shop can service it. Have it set up and bench-checked by a qualified technician before your first dive. Read How to Pick Scuba Regulators That Fit Your Diving. More options: Regulators.
