The Scubapro Hydros Pro BCD and the newer Hydros Pro 2 BCD are both premium back-inflation buoyancy control devices designed for divers who want modularity, durability, and travel-friendly performance. While they share the same core design philosophy, the second-generation Hydros Pro 2 introduces several engineering updates, weight reductions, and usability refinements. Understanding the differences between these two scuba BCD systems helps divers choose the right model for their diving style, travel needs, and gear preferences.
Design Philosophy and Core Similarities
Both models are built around a modular BCD platform, allowing divers to customize or replace components such as pockets, straps, and accessories without stitching. This extends service life and allows configuration for recreational, travel, or technical diving setups.
Each uses a Monprene® gel harness known for durability, flexibility, and resistance to UV, chemicals, and saltwater exposure. Both are also back-inflation BCDs, providing streamlined trim underwater and unobstructed chest movement compared to jacket-style BCDs.
Key Differences Between Hydros Pro and Hydros Pro 2
1. Weight and Back Plate Design
The Hydros Pro 2 features a redesigned Ergo-Lite back plate that is significantly lighter than the original Hydros Pro back plate. This reduction contributes to improved comfort during transport and topside handling. In addition, the new plate is molded to better match body contours and includes flex zones for natural movement.
2. Overall Weight Reduction
Beyond the back plate, material updates and a redesigned pocket system make the Hydros Pro 2 lighter overall than the original model, improving portability and making it more suitable for travel diving.
3. Weight System Mechanism
The Hydros Pro 2 introduces a monorail weight system, where weight pockets slide and lock onto a rail for one-handed installation and release. This replaces the earlier pocket design on the original Hydros Pro and simplifies weight insertion and ditching.
4. Bladder Material and Drying Speed
The second-generation model uses a heavy-duty quick-dry bladder made from abrasion-resistant fabric that does not absorb water. This allows the BCD to dry quickly and reduces post-dive weight during travel.
5. Tank Strap System
The Hydros Pro 2 includes an updated tank band designed to make cylinder changes faster and easier while maintaining a secure grip. The original Hydros Pro uses the earlier version of this system.
6. Streamlining and Trim Improvements
The newer model incorporates a tri-bungee retraction system and internal air channels that keep the wing compact underwater, reduce drag, and help distribute air evenly for stable buoyancy.
7. Travel and Packing Features
While both BCDs are travel-capable, the Hydros Pro 2 adds a folding design that allows straps to fold flat and wrap into the wing for easier transport.
8. Customization Options
The Hydros Pro 2 expands personalization with optional pocket sizes depending on water conditions and offers multiple color options for weight pockets.
Specification Snapshot (Hydros Pro 2 Reference)
- BCD type: back-inflated
- Lift capacity: approximately 40 lb
- Multiple D-rings for accessory attachment
- Integrated weight system with trim pockets
- Lightweight construction for travel
- Durable gel harness and abrasion-resistant fabrics
Original Hydros Pro Strengths
The first-generation Hydros Pro remains a highly capable modular BCD with a moldable harness, adjustable fit, and multiple attachment points. It can quickly switch between a lightweight travel harness configuration and a fully integrated weight system, making it versatile for both local diving and destination trips.
Which One Should You Choose?
The Hydros Pro is still a strong option for divers who want a proven modular BCD with travel capability. The Hydros Pro 2 is better suited for divers seeking the latest engineering updates, lighter weight, faster drying materials, and improved ergonomics. In practical terms:
- Choose Hydros Pro if you want a reliable modular BCD and prefer a slightly lower cost or already own compatible accessories.
- Choose Hydros Pro 2 if you prioritize lighter travel gear, faster drying materials, and the newest weight-system design.
Summary
The Hydros Pro 2 is not a complete redesign but a refinement of an already premium scuba BCD platform. It keeps the modular architecture and durable harness of the original Hydros Pro while improving portability, ergonomics, and convenience. For most divers, the choice comes down to whether the lighter construction and upgraded systems of the second generation justify upgrading or buying the newer model.
