Compact, ultra-rugged vented rubber fin based on one of the earliest vented designs sold in North America. This model has been a standard-issue fin for military, special operations, coast guard and public safety divers for decades.

• Short, wide blade provides maximum forward thrust while maintaining excellent maneuverability.
• Vented blade reduces resistance on the upstroke and enhances thrust on the downstroke; vents also reduce vortex formation along the blade similar to split fins.
• Improved foot pocket with spring straps for easier donning and doffing with cold hands or thick gloves; spring straps included as standard.
• Durable blade material engineered to withstand harsh environments, extreme temperatures, and heavy use.
• Two large grommet holes accommodate most karabiners for convenient storage while accessing dive sites.
• Custom-designed buckle holds spring straps in the optimal position.
• Simple push-pin construction allows straightforward replacement of springs when necessary.
