How varying wetsuit thickness effects buoyancy throughout the dive for freediving and spearfishing

The reason we wear weights when we freedive or spearfish is to, on the whole, compensate for the additional buoyancy created by the neoprene of our wetsuits. The colder the water, the thicker the wetsuit, therefore the more weight we have to wear to create the correct level of buoyancy. For freediving the average rule of thumb is to create …
