Scubapro Hydros Pro 2 BCD + Mini Monorail Weight Pockets
The Scubapro Hydros Pro 2 BCD is a next-generation, modular wing-style BCD that builds on the original Hydros Pro, focusing on improved comfort, faster drying, easier travel, and smarter weight handling. The mini-size Monorail Weight Pockets included hold up to 2.25kg per side.
Its Ergo-Lite Backplate is 25% lighter than the original. It features an innovative Monorail Weight System, Instant Dry technology, and a new Super Cinch 2 tank band for a lightweight, customisable, and travel-friendly diving experience in warm or cold water.
The lighter, stronger, modular and compact travel companion engineered for divers who demand the best.
With a modular design, premium materials, and travel-ready features, the Hydros Pro 2 is built for ultimate performance in all dive conditions. It's suitable for recreational diving in warm and cold water.

Key features:
- Intuitive Monorail Weight System: Weight pockets slide and lock into place via a monorail system for easy, single-handed operation. Simply pull the grey D-handle to release. The included mini-size Monorail Weight Pockets hold up to 2.25kg per side.
- Dries Quickly After Use: The heavy-duty quick-dry bladder’s Instant Dry Technology enables the BCD to dry almost instantly, making it ideal for travel due to less water retention and lower post-dive weight.
- Long-Lasting Durability: Built to last with a fabric-free Monprene® gel harness and double-coated fabric bladder designed to resist abrasion and fading from pool chemicals, saltwater and sunlight. Anti-abrasion Cordura® fabric on the dorsal weight-wing adds further protection against abrasions.
- Lightweight Ergo-Lite Back Plate: The Ergo-Lite back plate is 25% lighter than the Hydros Pro’s and features a body-contoured shape, soft padding, and dual top and bottom handles for easy two-handed loading.
- Comfortable, Ergonomic Design: Body-contoured shape and 3D ergonomic design hug the body for a weightless feel. The Torso Flex Zone automatically adjusts to your torso length for excellent comfort and freedom of movement. Unrestricted internal air-flow design reduces air trapping, so you enjoy greater manoeuvrability and can easily deflate the BCD from any angle or position.
- Designed for Easy Tank Swapping: Super Cinch 2 tank band is simple, ultra-durable, and incredibly easy to use and adjust. Enables fast, easy tank switching, whether you’re swapping tanks between dives or switching between aluminium 80s and steel tanks when travelling.
- Smart-Pack Design: The shoulder and waist straps fold flat against the backpack and wrap around the wing for easy transport and storage.
- Articulated Shoulder Straps & Kit-Up Assist: Shoulder strap hinges lock in the open position for easy donning, then fold flat to allow the Hydros Pro 2 to pack down for travel.
- Stays in Place During the Dive: Body grip gel helps the BCD grip your body, preventing shifting and riding up while diving.
- Streamlined Construction: Tri-bungee retraction system with 2-stage inflation delivers a more streamlined, compact air-cell underwater, providing even air distribution and higher lift capacity at the surface.
- Neutrally Buoyant: Near-zero inherent buoyancy means less lead and better control underwater.
-
Self-Draining Weight Pockets: Weight pockets are self-draining for an easy, hassle-free experience. Standard size holds up to 4.5 kg per pocket.
-
BC-4-Life Modular Design: With the BC-4-Life Modular Design, components are fully customisable and interchangeable, simplifying repairs and extending the BCD’s lifespan.
- Customise with Accessories: The Multi-Mount System on the BCD features multiple D-rings and mounting points to easily configure your BCD. Optional Multi-Mount Accessory Plates and Hydros Bungee Sets are sold separately and easily attach knives, lights, pockets, SMBs, hoses, and more.

Product FAQs
What is the difference between Hydros Pro and Hydros Pro 2?
• Monorail Weight System: Replaces the older weight pocket insertion design with a notched rail system that allows weight pockets to slide on, lock securely, and be ditched with a single-handed pull.
• Ergo-Lite Back Plate: Redesigned to be 25% lighter than the original back plate, featuring improved body-contouring, flex zones for natural movement, and top/bottom handles for easier handling.
• Heavy-Duty Quick-Dry Bladder: Uses an Instant Dry fabric coating that repels water, reducing post-dive water retention and drying significantly faster for travel.
• Tri-Bungee Retraction System: Uses a 2-stage inflation bungee setup that keeps the air cell compact underwater and lowers drag while maintaining full surface lift.
• Super Cinch 2 Tank Band: Upgraded buckle design for faster, easier tank swaps between different cylinder diameters (e.g., aluminium 80s to steel tanks).
• Enhanced Packing Features: Shoulder strap hinges lock open for easier donning and fold completely flat against the back plate to roll into the wing.
Is the Hydros Pro 2 suitable for dive travel?
• Low Post-Dive Weight: The fabric-free Monprene® harness and quick-dry bladder do not absorb water, ensuring your gear stays light when packing up after a dive trip.
• Smart-Pack Folding: The shoulder and waist straps fold flat, allowing the entire harness structure to fold inside the wing's footprint.
• Included Travel Bag: It comes with a dedicated BCD Carry Backpack designed to fit and carry the folded Hydros Pro 2.
Is the Hydros Pro 2 also suitable for cold-water or drysuit diving?
If your regular diving is in cold water and using drysuit, we would advise considering a more traditional wing setup based on a webbing harness and a two-layer wing made out of an inner bladder and outer protective shell such as the Xdeep Zeos, Zeos Deluxe or similar.
The Hydros Pro 2 offers:
High Lift & Ballast: With up to 40 lbs of lift, it can handle the extra weight and buoyancy requirements of thick neoprene or drysuit undergarments.
Self-Adjusting Torso Flex Zones: The Monprene® harness features dynamic flex zones and articulated shoulder straps that automatically expand and contract. You can switch between a 3mm tropical suit and a bulky drysuit without tedious strap readjustments.
Zero Buoyancy Retention: Because the harness and quick-dry bladder absorb no water, the BCD adds zero positive buoyancy, meaning you don't need to carry extra lead just to submerge a waterlogged harness.
How does the new Monorail Weight System work?
• Attachment: Weight pockets slide onto a notched track until you feel and hear an audible click confirming they are locked in place.
• Release: In an emergency or during boat hand-offs, pulling the integrated grey D-handles releases the pockets smoothly with one hand.
• Sizing Options: Standard weight pockets (up to 10 lbs / 4.5 kg per pocket) and are compatible with optional Mini travel weight pockets (up to 5 lbs / 2.3 kg per pocket). Rear dorsal trim pockets on the tank band can provide additional ballast balancing.
What material is the wing and harness made of?
This is what gives the harness its soft, rubbery grip against your exposure suit, preventing water absorption and making it immune to UV or chlorine degradation.
The Wing: The wing is the actual inflatable back-inflation air bladder. It is made from a heavy-duty, double-coated fabric bladder treated with an "Instant Dry" water-repellent coating, and reinforced with Cordura® fabric in high-wear zones (such as the dorsal trim weight areas) to resist scrapes against rocks or wrecks.
How much lift capacity and total weight can the Hydros Pro 2 carry?
Integrated Lead Capacity: Main Monorail Pockets: Standard pockets hold up to 10 lbs (4.5 kg) per side (20 lbs / 9 kg total). Optional Mini travel pockets hold up to 5 lbs (2.25 kg) per side.
Rear Trim Pockets: Fixed onto the tank band, these hold up to 5 lbs (2.25 kg) per pocket (10 lbs / 4.5 kg total) for fine-tuning trim.
Please be careful when deciding how much integrated weight to use, depending on your kit configuration and diving style.
