Sea Pearls Lace-Thru Dive Weight 4.0 Pounds, Die-Cast Contoured Uncoated Lead for Secure Fit

Sea Pearls Lace-Thru Uncoated Weight (4 lbs) is a contoured, die-cast lead dive weight designed to lace through standard weight-belt webbing for stable, low-profile ballast.

Built from reclaimed battery lead refined into a hardened alloy, this 4-pound Sea Pearls weight delivers consistent density and a smooth, rounded shape that sits comfortably against your body and integrates cleanly with nylon or rubber belts. The lace-thru configuration keeps the weight secured and evenly distributed, making it a practical option for both standalone weight belts and weight-integrated buoyancy compensators. Note: contains lead; follow local safety guidance and California Proposition 65 warnings.

How does the lace-thru design improve fit and security?

The lace-thru slot allows belt webbing to pass directly through the weight, locking it into place and minimizing lateral movement while you dive. This reduces slippage and keeps ballast positioned where you need it for trim and comfort.

• Webbing passes through the weight for secure attachment
• Reduced shifting compared with clip-on or loose weights
• Works with most standard nylon and rubber belts

What makes the material and construction reliable?

Sea Pearls uses reclaimed lead combined with antimony and tin to create a hardened alloy that resists deformation and keeps its shape under repeated use. The die-casting process and multi-cavity molds produce uniform pieces with consistent weight tolerance and a smooth finish.

• Alloyed with antimony for added hardness and durability
• Die-cast manufacturing for consistent, repeatable weights
• Rounded, contoured exterior to minimize pressure points

Will this weight work with integrated BCD pockets or only traditional belts?

The contoured shape and lace-thru configuration make this weight versatile: it functions well on a conventional webbing belt and is suitable for some integrated weight systems that accept lace-thru style weights. Always check your BCD pocket dimensions and retention method to ensure compatibility before use.

• Designed for use on nylon and rubber weight belts
• Compatible with many weight-integrated BCD pockets that accept lace-thru pieces
• Check pocket width and closure type to confirm fit

How comfortable and ergonomic is the 4 lb shape during a dive?

The weight’s rounded, contoured profile is specifically shaped to reduce hotspots and pressure against the hips and lower back. Its smooth edges and uniform mass help maintain diver comfort, especially on longer dives or when wearing thin exposure suits.

• Contoured edges reduce sharp pressure points
• Rounded surfaces sit snugly against the body
• Maintains balance while minimizing interference with movement

Who is this for: The Sea Pearls Lace-Thru Uncoated 4 lb weight suits recreational and technical divers seeking a durable, low-profile ballast piece for weight belts and compatible integrated systems. It is ideal for divers who want consistent, hardened lead alloy weights with a contoured fit and secure lace-thru attachment. If you require coated or quick-release style ballast, consider alternate Sea Pearls models instead.
