The BCD That Changed My Mind About BCDs

I have been diving long enough to go through three BCDs - from a basic jacket style to a hybrid back-inflate to a dedicated wing-and-plate setup. When I first heard about the Scubapro Hydros Pro, I was skeptical. Injection-molded thermoplastic? It sounded like a gimmick. After 60+ dives across destinations from Bali to Japan to California, I can confidently say this is the most well-thought-out recreational BCD on the market.

The Monprene Difference

Monprene is a thermoplastic elastomer that Scubapro injection-molds into the Hydros Pro harness and backplate. The material feels like a cross between silicone and stiff rubber. It is completely non-absorbent, unlike traditional nylon or Cordura fabric. After rinsing, a quick shake and a minute in the sun and it is bone dry. No more hanging BCDs in the garage for days hoping the inside dries before mildew sets in.

The material is also UV-resistant and will not fade or degrade. The harness spring retains its shape indefinitely. And critically for travel divers, the Monprene backplate is neutrally buoyant - it does not add positive buoyancy that needs to be offset with extra lead. This is a stark contrast to traditional back-inflate wings that require 2-4 lbs of extra weight just to counteract the lift of the nylon bladder material.

Comfort and Fit

The Body Glide Gel panels on the shoulder straps and backplate are a revelation. These soft, grippy silicone-like strips prevent the BCD from shifting or riding up, even with a heavy steel tank. No more yanking on shoulder straps to reposition during a dive. Once you dial in the fit, the BCD stays put. The ergonomic backplate contours to your spine without the hard edges of traditional hard-shell backplates.

The weight integration is the best I have used. The front-mounted weight pockets slide onto a rail system and lock with a satisfying click. They are completely secure yet release with a single pull when needed. The rear trim pockets sit flush against the backplate and add or remove easily without taking the BCD off. Total weight capacity is about 20 lbs.

Buoyancy and Diving Performance

The Hydros Pro is a true back-inflate design with the air cell positioned behind the diver. This means you float in a natural face-down swimming position underwater rather than being tipped forward by a jacket-style air cell. At the surface, you lean back slightly - not as upright as a jacket BCD, but not as extreme as some dedicated wings that have you floating face-up.

The two-stage inflation system with Tri-Bungee cords creates even air distribution across the cell. No air trapping in one corner. The bungee cords also actively retract the air cell during deflation, keeping the profile streamlined. At depth, the cell compresses naturally and the bungees maintain a smooth contour against the backplate.

Pockets and Storage

This is where the Hydros Pro makes compromises. The pockets are removable/replaceable via the Monprene rail system, but the stock pockets are smaller than what you will find on traditional BCDs. A large SMB will not fit comfortably. I found myself using a pocket snorkel keeper and clipping my SMB to a D-ring instead. The trade-off is that the BCD is much sleeker without bulky pockets, and you can swap them for different pocket configurations.

D-rings are plentiful: two on the chest, two on the waist, and a small one on the left chest for a console retainer. For tech divers, this may not be enough. For recreational diving, it is more than sufficient.

Wait, There is a Catch

The price. The Hydros Pro retails around $1,200, which is firmly in premium BCD territory. The modular design means you can replace almost any part without stitching, so long-term ownership costs are lower, but the upfront sticker shock is real. The original Hydros Pro has been replaced by the Hydros Pro 2 (late 2025), which adds the Monorail weight system (slide-and-lock instead of the original push-button) and a 25% lighter backplate. If buying new, get the Pro 2. If you find a good deal on the original, it is still an excellent BCD.
