Understanding Neck Weights for Freediving

The Purpose of Neck Weights

The main function of neck weights in freediving is to help with your buoyancy. Having a properly-weighted neck weight facilitates smooth descents and ascents without struggle or excessive energy expenditure. Adding weight to your neck enables your body position to be more streamlined (horizontal), making your dives more efficient and enjoyable.

How do you know the right amount of weight to use? That’s where the art of weighting yourself for freediving comes in. Too little weight can make you too buoyant and too much, too negatively buoyant. It’s essential to strike a balance to optimise your diving experience.

Types of Neck Weights

Neck weights come in various designs, shapes, and materials. Generally, there are two primary types you’re likely to encounter:

  1. Pre-made neck weights: Widely available at diving shops, pre-made neck weights usually come in standard weights — ideal for most divers. Designed to be easily adjustable, they’re user-friendly, durable and practical.
  2. DIY neck weights: Feeling creative? Some divers opt for making their own neck weight for maximum customisability! These weights allow you to tailor the amount of weight precisely to your unique buoyancy needs. Get crafty with simple and accessible materials like a thick tube sock or stockings, some sand, cable ties and voila – your personal neck weight is ready for action!

Ahoy divers, now that you’ve dipped your toes into the world of neck weights, you won’t be caught off guard the next time you spot one during a freediving session. Remember, even in the deep blue sea, knowledge is your best buddy!

Selecting the Right Neck Weight

Selecting the Right Neck Weight

Finding the perfect neck weight for freediving can be a bit of a challenge, but worry not, you’re in the right place. In this section, we’ll dive into the key factors to consider when selecting a neck weight that ticks all the boxes: material and durability, weight options and adjustability, and comfort. So, let’s take a plunge into the world of neck weights.

Material and Durability

When it comes to materials, you want a neck weight that is not only comfortable but also durable. Silicone and lead shot are popular choices in the freediving community. Silicone offers a soft touch against your skin and helps distribute the weight evenly for a more streamlined position. It also has the added bonus of being resistant to saltwater, making it perfect for those ocean dives.

Lead shot, on the other hand, provides the actual weight. Encased in the silicone, lead shot adds the necessary mass to counteract your buoyancy. It’s important to ensure the lead shot used is of high quality, ensuring your neck weight is durable and long-lasting.

Weight Options and Adjustability

Neck weights are all about finding the perfect balance underwater. That’s why having a neck weight that offers adjustability is crucial. Look for neck weights with segments of varying weights, like 300g (10.5oz) segments. This allows you to add or remove segments to fine-tune the perfect weight for your buoyancy needs.

Depending on your experience level and personal preference, you might consider neck weights ranging from 1kg to 3kg. Keep in mind, though, what’s most important is getting that balance just right. After all, you don’t want to be bobbing up like a cork or sinking like a stone, do you?

Comfort and Secure Fit

Comfort and Secure Fit

Last but definitely not least, let’s talk comfort. A neck weight should fit snugly around your neck without feeling too restrictive or causing any discomfort. Adjustable straps and secure fastenings can help you find the perfect fit that stays in place during your dive.

When selecting a freediving neck weight, think about how it will feel as you move through the water. A comfortable neck weight will allow you to focus on your dive without any distractions, ensuring a smooth glide and an enjoyable experience.

In summary, a great neck weight for freediving should be made of durable materials like silicone and lead shot, offer adjustability for the perfect balance, and provide a comfortable and secure fit.

Using Neck Weights Correctly

Using Neck Weights Correctly

By now, you probably know that using neck weights correctly is crucial for an enjoyable and safe experience. Let’s cover proper weight distribution and balance, maintaining a streamlined body position, and adjusting for wetsuit thickness. So, let’s dive in, shall we?

Weight Distribution and Balance

Neck weights help you achieve neutral buoyancy, making it easier for you to glide underwater without constantly fighting to stay submerged. But how can you ensure optimal weight distribution?

Start by placing the neck weight close to your body’s centre of gravity, typically near your collarbone. This provides better balance and ensures that your head and upper body are not dragged down by the weights.

Don’t make the rookie mistake of placing all the weights at the back, as it might tilt your body position and hinder your hydrodynamic efficiency. Remember, the goal is to find the sweet spot that helps you maintain a horizontal position in the water.

Streamlined Body Position

A streamlined body position is essential for efficient freediving. It not only conserves your energy but also aids in your overall movement through the water. To achieve this hydrodynamic profile, keep your legs straight and aligned with your hips, and slightly tuck your chin towards your chest.

Funnily enough, your body acts similarly to a torpedo when streamlined, allowing you to glide more efficiently underwater. But don’t worry, you won’t be causing any underwater explosions, I promise!

Adjusting for Wetsuit Thickness

Adjusting for Wetsuit Thickness

Wetsuits come in various thicknesses, affecting your overall buoyancy. Thicker wetsuits are more buoyant, so you’ll need to adjust your neck weights accordingly.

For example, if you’re wearing a 5mm wetsuit, you might need to add a bit more weight than with a 3mm suit. Keep in mind that finding the perfect balance requires some experimentation on your part.

There you have it! Understanding proper weight distribution, maintaining a streamlined body position, and adjusting for wetsuit thickness can help make your freediving experience much more enjoyable and safe. Now, go on and have a blast exploring the underwater world with your newfound knowledge of neck weights!

Neck Weights for Different Freediving Disciplines

Did you know that neck weights can vary for different freediving disciplines? Oh yes! Let’s dive into the specifics of neck weights for pool disciplines, depth disciplines, and spearfishing. Time for submerging ourselves into the fascinating world of freediving, We think!

Pool Disciplines

When it comes to pool disciplines like dynamic apnea, freedivers need to balance their buoyancy to streamline their movement and conserve energy. In this setting, you might opt for a slightly lighter neck weight compared to depth diving.

The goal is to achieve neutral buoyancy, which means you’ll neither sink nor float. But be careful – you don’t want to go too light, as it might make it difficult to stay submerged. Practice makes perfect, so it’s crucial to find that sweet spot tailored to your unique freediving style.

Depth Disciplines

Depth disciplines, such as constant weight, free immersion, and no-fins, require freedivers to go deeper into the ocean’s abyss. In these disciplines, a heavier neck weight can prove advantageous. As you descend, your wetsuit compresses, causing you to lose buoyancy.

Therefore, having a slightly heavier neck weight helps you maintain your neutral buoyancy throughout the dive. Just remember, every freediver is different, so experiment to find the perfect weight that suits your body and diving preferences.


Now, let’s talk about spearfishing! In this discipline, stealth and agility are critical. A weight belt might get in the way, so many spearfishers opt for neck weights instead. This alternative offers more flexibility for moving through the water or quickly changing depths.

Aiming for neutral buoyancy at around 10 meters (33 feet) is ideal for spearfishing, as it allows you to minimise the effort needed to move horizontally while stalking your prey. Of course, you’ll still need to experiment to find the perfect weight for you.

So, whether you’re a pool freediver, a depth diving fanatic, or a spearfishing enthusiast, the right neck weight can make all the difference. Finding the optimal weight for your discipline might take a little trial and error, but once you’ve nailed it, there’s no stopping you from exploring the tantalising depths of the ocean with ease and grace!
