Zeagle Envoy II Scuba Diving Regulator
By Zeagle | High-Performance Diaphragm First Stage | 5 LP & 2 HP Ports | Venturi Assisted 2nd Stage
Experience outstanding breathing performance without the premium price tag with the Zeagle Envoy II Scuba Diving Regulator. Engineered to match or exceed the delivery rates of regulators costing significantly more, the Envoy II represents unmatched value for recreational sport divers, travel enthusiasts, and dive centres looking for bulletproof reliability.
The system pairs a lightweight, chrome-plated brass diaphragm first stage featuring a generous 5 low-pressure port layout with a compact, ergonomically tuned downstream second stage. Whether configured as your primary breathing system or an ultra-dependable octo backup, the Envoy II delivers consistent airflow and smooth inhalation across recreational sport diving depths.
Conical Precision HP Valve & 5 Low-Pressure Ports
Equipped with Zeagle's proprietary conical precision high-pressure valve and advanced polymer seat, the Envoy II first stage minimizes internal friction and seat wear. With 5 low-pressure ports (3/8"-24 UNF) and 2 high-pressure ports (7/16"-20 UNF), hose routing for drysuits, transmitters, and backup second stages is clean and effortless.
Envoy II First Stage Highlights
- High-Performance Diaphragm Design: Unbalanced diaphragm mechanism engineered for crisp pressure response and simple, low-cost maintenance.
- Generous 5 LP / 2 HP Port Array: Five 3/8"-24 UNF low-pressure ports provide ideal hose alignment for primary, octo, BCD inflator, and drysuit hoses.
- Conical Precision HP Valve: Stainless steel high-pressure valve with an advanced polymer seat delivers extended working life and consistent intermediate pressure (135–150 psi / 9–10 bar).
- Lightweight Brass Body: Compact 1st stage weighs just 1.88 lbs (0.85 kg), making it a great option for travel gear bags.
- Connection Options: Available in standard 232 Bar Yoke or 300 Bar DIN connections.
Envoy II Second Stage Highlights
- Classic Downstream Demand Valve: Time-tested downstream poppet design provides failsafe safety and smooth, predictable airflow.
- Dive / Pre-Dive Venturi Assist: Integrated venturi control lever prevents nuisance surface free-flows and boosts gas flow efficiency while submerged.
- Compact & Featherweight: Weighs only 0.42 lb (0.19 kg) without hose, reducing jaw fatigue on longer dives.
- Flexible 30" Rubber LP Hose: Durable 30-inch (76 cm) low-pressure hose included.
