Do you need a weight belt for spearfishing? A weight belt is often used in spearfishing to help divers achieve proper buoyancy and control underwater. The need for a weight belt depends on the diver’s body composition and the thickness of their wetsuit.

How fast do spearguns shoot? The speed at which spearguns shoot varies depending on factors like band tension, spear type, and gun design. On average, spearguns can shoot at speeds of 30 to 60 feet per second (9 to 18 meters per second).

What is the range of a 110cm speargun? A 110cm speargun typically has an effective range of approximately 10 to 20 feet (3 to 6 meters), depending on various factors, including the gun’s power and the skill of the shooter.

How long do I need to hold my breath for spearfishing? The duration of holding one’s breath for spearfishing varies from person to person and depends on factors like fitness, diving depth, and experience. Experienced spearfishers may hold their breath for 1 to 2 minutes or more.

Why is spearfishing difficult? Spearfishing can be challenging due to the need for breath-holding, diving skills, and precise aiming. It also requires an understanding of marine ecosystems and fish behavior.
