Open Box BCDs — Buoyancy Systems at Reduced Prices

BCDs come back more often than almost any other piece of dive gear, and the reason is almost always sizing. A diver orders a medium, finds it rides wrong across the shoulders, and returns it. The BCD is functionally untouched — but once the bag is opened it can't be sold as new. That's most of what's in this collection.

The category covers jacket-style BCDs, back-inflate designs, travel BCDs, women's-specific fits, and technical backplate-and-wing systems from Scubapro, Zeagle, Hollis, Aqua Lung, Sherwood, Mares, Oceanic, and others. Every item is inspected and graded before listing; see Product Conditions for full definitions.

Sizing Is the Main Thing to Get Right

Since sizing is why most of these came back, it's worth being deliberate about it. BCD sizing is not consistent between manufacturers, and a medium in one brand can fit like a large in another. Check the manufacturer's size chart for the specific model rather than relying on your size in a different brand.

Also consider what you'll wear underneath. A BCD sized over a 3mm tropical suit will be tight over a 7mm suit or a drysuit. If you dive both, size for the thicker configuration and use the adjustment straps to take up slack for warm water.

What to Check Before Ordering

• Inflator condition. The power inflator is the mechanical heart of the BCD. Have it checked and serviced along with your regulator before diving.
• Bladder integrity. Inflate fully and leave it overnight when it arrives. A bladder that holds pressure is sound; one that sags needs attention before it goes in the water.
• Weight pockets included. Integrated weight systems sometimes get separated from the BCD. Confirm the listing includes what you expect.
• Lift capacity. Match to your cylinder type and exposure suit — more lift isn't automatically better, and excess creates drag.
• Dump valve operation. Check that shoulder and lower dumps pull cleanly and seal afterward.

Frequently Asked Questions

How do I check a used BCD is sound when it arrives?

Inflate the bladder fully and leave it overnight — it should still be firm in the morning. Work the power inflator and confirm it both inflates and deflates cleanly. Pull each dump valve and check it reseals. Inspect webbing and stitching at load points, and check that buckles latch positively.

Does the BCD need servicing before I dive it?

The power inflator should be inspected and serviced, since it's a mechanical component connected to your gas supply. Have it looked at alongside your regulator service. The bladder and harness you can assess yourself with the overnight inflation test.

Do open box BCDs come with a warranty?

No. Open box and used products are not eligible for manufacturer warranty coverage. If warranty matters to you, buy new.

What if the size is wrong when it arrives?

Open box and used purchases can be returned within 30 days with RMA approval. Note that on open box and used items the customer pays for the return label rather than receiving a free one — so it's worth checking the size chart carefully before ordering.

Are the integrated weight pockets included?

Usually, but confirm on the listing. Weight pockets occasionally get separated from a BCD during a return. If the listing doesn't specify and it matters, contact us and we'll check the actual item.
