Scubapro Seahawk 2 BCD with AIR2

The Seahawk 2 is a traditional back-inflation BCD: the air cell sits behind you for a streamlined profile and stable horizontal trim, while up front you get quick-release integrated weight pouches, two rear trim pouches, and six stainless D-rings for accessories. It is built from tough 1000- and 420-denier nylon with a reinforced soft backpack and Super Cinch stainless tank band, and comes in sizes 2XS–2XL with your choice of BPI or AIR2 inflator.

Per ScubaPro's official size chart: 38.2 lbs (17.3 kg) of lift in 2XS and XS, and a substantial 54 lbs (24.4 kg) in sizes S through 2XL — enough for cold-water rigs and heavy steel tanks. Dry weight with the inflator runs 6.8–7.5 lbs depending on size, so it packs reasonably for a full-featured back-inflate.

Both are back-inflation BCDs, but they are built differently. The Seahawk 2 is the classic approach: durable nylon fabric, a padded soft backpack, and proven quick-release buckle weight pouches. The Hydros Pro 2 is ScubaPro's modular flagship: an injection-molded Monprene gel harness that molds to your body, the Monorail slide-and-lock weight system, an Ergo-Lite back plate, and an instant-dry bladder. The Seahawk 2 delivers more lift per size at a lower price; the Hydros Pro 2 offers the custom fit and modularity.

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.

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.

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.

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.

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.

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.

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.

The Seahawk 2 runs 2XS through 2XL, and one thing to know is that lift changes at the size break: 38.2 lbs (17.3 kg) in 2XS and XS, and 54 lbs (24.4 kg) from S through 2XL. Use ScubaPro's official size chart as the starting point, and if you land between sizes send us your height, weight and torso length — we fit these regularly and can get it right the first time.

Yes — unlike the Hydros Pro 2, whose Monorail pockets are a separate purchase, the Seahawk 2 has quick-release integrated weight pouches built into the front plus two rear trim pouches. For most recreational diving that replaces a weight belt entirely. If you want the exact ballast capacity for your size, ask us and we will confirm before you order.

It is one of the better-suited back-inflates for it. Sizes S through 2XL carry 54 lbs (24.4 kg) of lift — enough for a thick suit and heavy steel cylinders — and the build is tough 1000- and 420-denier nylon with a reinforced soft backpack, a Super Cinch stainless tank band and six stainless D-rings for accessories. Dry weight still lands at a manageable 6.8–7.5 lbs with the inflator.

The BPI version comes with ScubaPro's standard balanced power inflator and you carry a separate octopus as your backup. The AIR2 version combines the inflator and a backup second stage in one unit, which removes the separate octopus and one hose for a cleaner rig. If you already own an octopus you trust, BPI is the simpler choice; if you want fewer hoses, go AIR2.
