Neck Weight

The Alchemy silicone freediving neck weight is designed to help you dive deeper, faster, and safer. Simply push on its sides, and watch it form with incredible precision around your neck. So adjustable, it practically disappears. Conceived to take advantage of next-level performance, its unreal hydrodynamics will enable you to glide seamlessly through the water, providing superior stability for all freediving disciplines. Whether at the pool or at sea, it pushes what’s possible, bringing a new level of efficiency, simplicity, and convenience. When it comes to freediving gear, the less is the best.

Utilizing aerospace-grade silicone and encapsulated lead, it is clearly tougher than any other neck weight of its class. The superiority of silicone, compared to common rubber, ensures stability, durability, and ease of use, while its sleek, innovative design guarantees that you’ll always stand out from the crowd.

Traditionally, freedivers and spearos wear a belt with weight around their waist to set their buoyancy as needed. However, when we freedive, we want to place the weights in the most efficient position on our body. Compared to the use of a weight belt, a neck weight has significant advantages. Why? The weight is below our lungs during the descent, pulling us down, and resulting in an effortless dive, especially while freefalling.

As the shape of the neck weight can be formed according to one’s needs, it will rest lightly on one’s jaw, without disturbing the mouthfill.

On bare skin or on a smooth, nylon, lycra, or super stretch wetsuit, the neck weight’s silicone sticks and won’t move around.

To determine the appropriate size for you, measure the circumference of your neck and choose the size that corresponds most closely to your measurement. If you plan to wear a wetsuit while diving, be sure to wear it when taking your measurements.

The neck weight you purchased is specifically designed for diving and swimming purposes. Using it for any other activity outside of water is not recommended and may result in the product failing or getting damaged, leading to potential personal injury. It is important to avoid attempting to remove the silicone material and strip the lead core, as this can expose you to dangerous substances such as lead. If you notice any damage or stripping of the outer silicone material, refrain from using the neck weight. Make sure to dispose of it responsibly by taking it to certified recycling facilities that accept materials containing lead, similar to batteries.

To prepare the neck weight for use, gently widen the opening by pulling the sides while simultaneously twisting your wrists. Continue until the neck weight expands enough to fit comfortably around your neck. When removing the neck weight, reverse the same motion to close it securely. It is important to ensure that the neck weight maintains its circular shape throughout the opening and closing process. Avoid simply pulling the edges apart forcefully, as this can create a single stress point that acts as a hinge and potentially damage the lead core of the neck weight. It is not recommended to straighten or reshape the neck weight, as doing so may reduce its lifespan. However, if absolutely necessary, you can gradually and evenly expand the neck weight until it becomes straight. Remember to avoid bending it at sharp angles to prevent any damage. Please store it in its original shape.

The Alchemy neck weight is designed to require minimal maintenance. If cleaning becomes necessary, you can use dish soap and a sponge to clean it. Rinse thoroughly to restore the silicone's adhesive properties. For stubborn stains that cannot be removed with soap, you can use a cloth dampened with pure acetone (not nail polish remover). Acetone is safe to use as a cleaning agent for silicone and will not cause any damage. Remember to clean with soap and rinse thoroughly after using acetone. If you observe bubbles emerging from the neck weight while using it, this may indicate a potential leak in the outer silicone cover. It is important to identify the precise location of the bubble formation. Please contact us so we can assist you in assessing whether a repair or service is possible for your neck weight.

Lead time may vary from 1 to 5 working days, depending on our workload and stock levels.
