Weight Systems

Master your buoyancy and improve your underwater trim with the SALT Of The Sea range of Weight Systems. Designed specifically for the needs of freedivers, spearfishers, and scuba divers, our collection focuses on stability, comfort, and reliable performance. Whether you are looking for a high-grip silicone Marseille belt to prevent slipping during your descent or precision-cast belt weights to fine-tune your ballast, we provide the essential Diving Gear required for a balanced dive. Every component is built to withstand the harsh Australian saltwater environment, ensuring you stay streamlined and focused on the blue.

What is this page best for?

This page is the primary destination for divers looking to customise their buoyancy control setup. It is best for those who need modular weight solutions that can be easily adjusted based on their environment or the specific Wetsuits they are wearing. Our systems are particularly popular with breath-hold divers who require a secure, quick-release belt that stays in place as neoprene compresses at depth. From recreational snorkelling to professional spearfishing missions, these weight systems offer the versatility needed to achieve neutral buoyancy with ease.

Choosing the right thickness

While weights themselves don't have a thickness, the amount of weight you need is directly determined by the thickness of your suit. Neoprene is highly buoyant, so thicker suits require more weight to submerge:

• 1.5mm & 3/2mm Suits: Generally require less weight, often paired with a streamlined belt setup for maximum mobility.
• 4/3mm & 5/4mm Suits: Increased buoyancy in these thicker Spearfishing Wetsuits requires a more substantial weight distribution to help you descend efficiently.
• Saltwater vs. Freshwater: Always remember that you will need more weight in the ocean than in a pool or lake due to the increased density of saltwater.

Warmth, stretch and durability

In a weight system, durability and reliability are the most critical factors. SALT Of The Sea Marseille belts are crafted from high-grade silicone, offering superior stretch and "grip" compared to traditional webbing belts. This elasticity ensures the belt stays tight around your waist even as your suit compresses, preventing the weights from shifting and affecting your balance. Our weights feature low-profile, hydrodynamic shapes to reduce drag, and our coated options provide extra protection against the elements. These systems are designed to be a long-lasting part of your kit, performing reliably season after season.

FAQs

What is a Marseille buckle and why is it better for diving?

A Marseille buckle features a classic roller and pin design that allows for a very secure fit while remaining easy to release with one hand in an emergency. It is the preferred choice for freedivers and spearfishers because it won't accidentally slip open, yet provides a reliable quick-release mechanism when needed.

How much weight do I need for my wetsuit?

The amount of weight varies based on your body composition, the thickness of your suit, and whether you are in fresh or salt water. As a general rule, start with approximately 5–10% of your body weight and perform a buoyancy check at the surface to ensure you are neutral at your desired depth.

Should I choose coated or raw lead weights?

Coated weights are often preferred as they are easier on your gear and less prone to oxidisation in saltwater. SALT Of The Sea offers black and white coated options to help you organise your kit and match your other Diving Gear, though raw lead remains a durable and functional choice for many divers.

How do I maintain my weight belt and weights?

To extend the life of your weight system, always rinse both the belt and the weights in fresh water after use to remove salt and sand. Store your silicone belt out of direct sunlight and away from sharp objects to prevent perishing or tearing, and check the buckle regularly for any signs of wear.
