Product Information

The ScubaPro Hydros Pro 2 BCD is available in 2 configurations. Select a configuration above to shop it, or expand each section below for that configuration's full features and specs.

Standard (up to 10 lbs) — features & specs

*This includes a Monorail Pocket Set of chosen color.

The Scubapro Hydros Pro 2 with Standard Monorail Weight (Up to 10 lbs) Pocket Set is a back-inflated, unisex, weight-integrated BCD rated for 35 lbs of lift, built around a fabric-free Monprene gel harness and the Monorail weight system that loads and releases the weight pockets with one hand. It is supplied with the BCD, a BCD carry bag and a Standard Monorail Weight Pocket Set in a matching color, which holds up to 4.5 kg (10 lbs) per pocket.

Who it is for

This is a single tank recreational BCD for divers who want one harness for travel and for diving at home. The Smart-Pack design folds to 23 x 11 x 5.5 in and the whole BCD weighs 8.378 lb, the heavy-duty quick dry bladder uses Instant Dry Technology so it dries almost instantly, and near-zero inherent buoyancy keeps your weighting predictable. The BC-4-Life modular construction lets you strip it down for travel and rebuild it for colder, heavier dives.

Key details

35 lbs lift capacity, back-inflated, unisex, with a max bottle size of 18L or 150 ft³.
Monprene Dual Compound backpack and an Ergo-Lite back plate that is 25% lighter than the original.
Monprene gel, polyester webbing and double PU coated fabric construction, with Cordura on the dorsal weight-wing.
8 D-rings in acetal, polypropylene and stainless steel, 2 back trim pockets and a Super Cinch 2 tank band.
Tri-bungee retraction system with 2-stage inflation, articulated shoulder straps with kit-up assist and body grip gel.
Choice of BPI balanced power inflator or Air2, which combines a backup regulator with buoyancy control in one unit.

Compatibility and sizing

Sizes run XS, S, M, L and XL/2XL in eight colorways. Cummerbund circumference is published as 26 to 38 in on the main product page, and 27 to 41 in for size S (item 21.963.200). Standard and Mini Monorail Weight Pocket Sets both fit, along with the Hydros Ninja Pocket, Hydros Pro Cargo Thigh Pocket and Hydros Pro Bungee Set. It is a single tank BCD and is not compatible with double tank setups, the original Hydros Pro monorail weight system or Hydros BCD Color Kits.

Mini (up to 5 lbs) — features & specs

The ScubaPro Hydros Pro 2 with Mini Monorail Weight Pocket Set is a back-inflated, weight-integrated BCD supplied with the Mini pocket set in the color you choose, giving 35 lbs of lift and weight pockets that each hold up to 5 lbs of lead. It is the Hydros Pro 2 supplied with the Mini pocket set, built around the Monorail slide-and-lock system that loads lead one-handed.

Who it is for

This package suits warm-water and travel diving: the listing's three modes pair Mini pockets with warm water and no pockets with travel and tropics. The fabric-free Monprene gel harness, body grip gel and 3D ergonomic shape keep the BCD against the body instead of letting it shift, and the Smart-Pack design folds the shoulder and waist straps flat to a packed size of 23 x 11 x 5.5 in. Because the BC-4-Life modular design is fully customizable and interchangeable, the same BCD can be rebuilt for temperate or cold diving later with Standard pockets that hold up to 10 lbs each, or dived with no pockets at all for travel and tropics.

Key details

35 lbs lift on a back-inflated, unisex air cell, with a BCD weight of 8.378 lb.
Ergo-Lite back plate in plastic, 25% lighter than the Hydros Pro back plate.
Heavy-duty quick dry bladder with Instant Dry Technology and double PU coated, abrasion-resistant fabric.
Super Cinch 2 tank band, with a maximum bottle size of 18L or 150 cu ft (single tank only).
8 D-rings in acetal, polypropylene and stainless steel, plus 2 back trim pockets.
Inflator choice of BPI balanced power inflator or Air2 alternate inflator regulator.

Compatibility and sizing

Sizes run XS, S, M, L and XL/2XL, with an adjustable harness with quick release buckles, shoulder, sternum and waist straps, and a cummerbund circumference of 26 to 38 in. Compatible accessories include the Standard pocket set, Monorail Multi-Mount Accessory Plate Set, HYDROS PRO Bungee Set, Hydros Ninja Pocket and Hydros Pro Cargo Thigh Pocket.

Frequently Asked Questions

What size ScubaPro Hydros Pro 2 should I get?

The Hydros Pro 2 is available in sizes XS through XL, and its Monprene gel harness molds to your body over time for a custom fit. Start with the ScubaPro size chart based on your height, weight, and torso length. If you are between sizes or unsure, contact us before ordering — we fit Hydros BCDs every week and can help you get it right the first time.

What is the difference between the Hydros Pro 2 and the original Hydros Pro?

The Hydros Pro 2 is the second generation of the award-winning Hydros Pro and succeeds it in ScubaPro's lineup. It keeps what divers loved — the moldable Monprene gel harness and fully modular BC-4-Life design — and adds the new Monorail slide-and-lock integrated weight system with one-handed, audible-lock operation, a roughly 25% lighter Ergo-Lite backplate, a heavy-duty quick-dry bladder, the Super Cinch 2 tank band, and a flat-folding Smart-Pack design that makes it easier to travel with.

Should I choose the Hydros Pro 2 with BPI or with AIR2?

The BPI version comes with ScubaPro's standard balanced power inflator, and you carry a separate octopus as your backup second stage. The AIR2 version combines the inflator and a backup second stage in one unit, which removes the separate octopus and one hose from your setup for a cleaner, more streamlined rig. If you already own an octopus you trust, BPI keeps things simple; if you want fewer hoses, choose AIR2.

Are weight pockets included with the Hydros Pro 2?

Weight pockets are not included with the base Hydros Pro 2 BCD — they attach via ScubaPro's Monorail system and are sold as separate pocket sets in Mini (up to 5 lbs per pocket) and Standard (up to 10 lbs per pocket) sizes. If the listing title includes a Monorail Weight Pocket Set, the pockets are included in that bundle at a package price.

How should a scuba BCD fit?

A BCD should fit snugly enough that it does not ride up toward your ears when inflated, while still letting you breathe fully. Fasten the waist and cummerbund first, then adjust the shoulder straps so the tank sits close to your back and the shoulders cannot slide off. With the BCD fully inflated at the surface you should still be able to take a deep, comfortable breath; if it squeezes your chest, loosen it or move up a size.

How do I rinse and care for a BCD after diving?

Rinse the outside in fresh water and also flush the inside of the bladder, because salt water gets in through the inflator and dump valves. Fill the bladder roughly a third full of fresh water through the oral inflator, slosh it around, then drain it out through the inflator and each dump valve. Hang it to dry out of direct sunlight and store it partially inflated so the bladder walls do not stick together.

Should I use integrated weights or a weight belt?

Integrated weight pockets carry the lead in the BCD itself, which many divers find more comfortable and easier on the hips, while a weight belt keeps the weight independent of your BCD. Either way, you must be able to release your ditchable weight quickly with one hand, and your buddy should know how your system releases. Non-ditchable trim pockets are useful for balance but should never hold weight you might need to drop.

How do I pack a BCD for travel?

Make sure the BCD is completely dry inside and out before packing so it does not mildew in transit. Remove all weights, deflate it fully, and fold or roll it around softer items such as a wetsuit to cushion the inflator and valves. Avoid hard creases in the air cell, and unpack and air it out as soon as you arrive.

When does a BCD need to be serviced?

Follow the service interval in the manufacturer's manual, which is commonly an annual inspection alongside the rest of your life-support gear. Have the inflator, dump valves, and bladder checked any time the inflator sticks, free-flows, feels rough, or the BCD holds air poorly. Between services, confirm that it inflates and deflates properly as part of every pre-dive check.

What is the difference between a jacket-style and a back-inflate BCD?

A jacket-style BCD holds air in panels that wrap around your sides as well as your back, while a back-inflate BCD keeps the entire air cell behind you. Jacket styles tend to feel very stable and upright at the surface, and back-inflate styles keep the chest clear and are often preferred for horizontal trim underwater. Neither is objectively better, so treat it as a fit and preference decision and try both if you can.

Will my BCD fit any scuba tank?

Most recreational BCDs use an adjustable cam band sized for common single-cylinder diameters, so standard aluminum and steel tanks generally work. Re-check the band tension after the first wetting, because webbing can relax slightly and let the tank shift. If you dive doubles or unusual cylinder diameters, confirm compatibility with the manufacturer before assuming it will hold.
