Diving weights are essential tools for both freediving and spearfishing, as they help divers achieve neutral buoyancy and control their descent while underwater. The appropriate weight depends on several factors, including the diver’s body composition, equipment, water temperature, depth, and individual preferences. Here are some guidelines to consider when choosing diving weights for freediving and spearfishing:

  1. Body Composition: Your body composition, including muscle mass and body fat, can affect your buoyancy. Generally, individuals with higher body fat percentages might need slightly more weight to achieve neutral buoyancy.
  2. Wetsuit or Exposure Protection: If you’re diving in colder water and wearing a thick wetsuit or drysuit, you’ll likely need more weight due to the added buoyancy of the suit. Be sure to account for the buoyancy changes caused by your exposure protection.
  3. Depth and Duration: Deeper dives require more weight to counteract the increased buoyancy from the compression of the wetsuit and the volume reduction of your lungs. Longer dives may also require additional weight, as your body becomes less buoyant with each exhalation.
  4. Equipment: The weight of your gear, such as fins, spearguns, and masks, can impact your overall buoyancy. Adjust your weight accordingly to achieve neutral buoyancy when fully equipped.
  5. Saltwater vs. Freshwater: Saltwater provides more buoyancy than freshwater due to its higher density. If you’re diving in freshwater, you might need slightly less weight than in saltwater.
  6. Trial and Error: It’s crucial to experiment with different weights to find what works best for you. Start with a weight belt that allows for easy adjustments, and gradually add or remove weights during your dives until you achieve optimal buoyancy and control.
  7. Safety: Always prioritize safety. It’s better to have slightly less weight and the ability to easily add weight if needed than to be over weighted and struggle with buoyancy issues.

Remember that the goal is to achieve neutral buoyancy, where you neither float to the surface nor sink uncontrollably.
