Fins and Monofins
Constant weight

Constant weight fins are crucial for deep dives, whether using bi-fins or monofins. To descend efficiently, you need equipment that propels you with minimal effort. Adequate power is essential to overcome both the positive buoyancy at the start of the dive and the negative buoyancy after ascending from the bottom. However, excessively stiff blades can waste energy with each kick, so achieving the right balance is key. For constant weight bi-fins, longer fins are typically preferred as they enhance the movements of the freediver. However, individuals with smaller statures may benefit from slightly shorter fins that offer quicker activation. In constant weight diving, it is especially important that the footpocket transmits energy to the blade with minimal loss. Comfort is also crucial, as any discomfort can impede concentration and performance.
