Apeks - Fins RK3 HD tg.XL

• Designed in collaboration with the US armed forces and renowned for exceptional performance and reliability, the Apeks RK3 is a robust thermoplastic rubber fin equipped with an oversized shoe to accommodate watertight wetsuit boots and a spring strap for easy on and off.
• The RK3 is available in three sizes: Medium, Large and Super. We did not give the RK3 fin a range of shoe sizes as this can be very misleading. Will the environment in which an RK3 is used tend to determine the size of the fin you need, such as dive into a warm environment wearing wetsuit boots or are you walking on pebble beaches and wearing a watertight wetsuit and dry rigid boots?

Based on one of the first vented rubber fins sold in North America and appreciated by military and professional divers. Compact and ultra robust for use in harsh environments. Improved shoe with spring straps for easy use with cold hands or thick gloves. The design has been for decades the standard fin of equipment for military, special operations, coastguard and public security divers. The short and wide blade provides maximum push forward while maintaining great maneuverability. Ventilated blade design reduces resistance when running upwards and improves thrust when running down. Air vents also eliminate vortices that can occur along the back of the shovel in the same way as the split fins eliminate the vortex. Blade material designed to withstand harsh environments, temperatures and abuse. Two large cable grommets designed to fit most carabiners to easily store fins while accessing the diving site. Elastic straps as standard. Custom designed buckle keeps spring straps in optimal position. The simple design of the thrust pin allows for simple replacement of the springs if necessary.
