Open Box Seac Smart BCD

Sale price $364.00 Regular price $455.00

Product Information

The Seac Smart BCD is a traditional jacket-style buoyancy compensator built with a reinforced PU-coated Cordura bladder and a quick-release Safety Release weight system. It is sized from 2XS to XL and weighs 6.8 lbs (3,100 g) in size L complete with hose and weight pockets.

Who it is for

The Seac Smart BCD is designed for beginner divers and travelers who want a compact, durable BCD without excess bulk. Its jacket-style design and straightforward weight-release handling make ballast management simple, and the compact build suits divers packing gear for trips.

Key details

Outer bladder material is PU-coated Cordura 1000, with an inner bladder of PU-coated Cordura 500, built into a reinforced bag.
Three pull-cord overpressure and dump valves manage air release from the bladder.
Six stainless steel D-rings, each 25 mm, are positioned for attaching accessories.
The Safety Release weight system uses a silver buckle and a high-visibility handle, with weight pockets that have two Velcro openings: an upper opening to insert lead and a lower opening for quick release in an emergency.
Separate side pockets hold weights and accessories, and the accessory pockets close with anti-corrosion zippers.
Dry weight in size L is 6.8 lbs (3,100 g), complete with hose and weight pockets.

Compatibility and sizing

The Seac Smart BCD is offered in six sizes: 2XS, XS, S, M, L and XL, so divers can match the jacket to their body size and layering needs.

DiveCatalog.com is an authorized Seac dealer and a dive shop in Irvine, California, serving divers since 2003. Call 888-701-4017 or chat with us if you have questions about sizing or fit before you order.

Frequently Asked Questions

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.

What sizes does the Seac Smart BCD come in?

The Seac Smart BCD is available in six sizes: 2XS, XS, S, M, L and XL. This range lets divers of different body sizes find a jacket-style fit, and DiveCatalog.com can help you confirm the right size based on your measurements before you order.

How does the Safety Release weight system on the Seac Smart BCD work?

Each weight pocket has two Velcro openings: an upper opening used to insert lead and a lower opening used for quick release in an emergency. The system also includes a silver buckle and a high-visibility handle, which simplify ballast management and let a diver release weight quickly when needed.

What materials are used in the Seac Smart BCD bladder?

The outer bladder is made of PU-coated Cordura 1000, while the inner bladder uses PU-coated Cordura 500. Both layers are built into a reinforced bag fitted with three pull-cord overpressure and dump valves for releasing air from the bladder.

How many D-rings does the Seac Smart BCD have?

The Seac Smart BCD has six stainless steel D-rings, each 25 mm, positioned on the jacket for attaching accessories such as clips, lights or a cutting tool.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.
