I lost one during my giant stride at the ocean. I was so lucky it's a positive fin and it was vertical position floating ?? and the dive master could catch it and I could dive. They are very good.

I have other friends who love these fins but I couldn't make them work for me.

I bought these because I liked the old military rocket fins and these fins work very well. I like that they are short which allows me to have more maneuverability while diving while offer plenty of propulsion. They are my new "go to fins" for diving. The spring strap are easy to get on and off but are very secure while diving. I prefer these over my ScubPro Seawing Novas which are great fins as well.

I guess the jury is still out on these, used for two dives and they seem okay, I'll know better after a few more dives, they seem heavy and that didn't work well in a dive where we had to kick-out a distance from the shore to avoid kelp...

Very maneuverable, easy to don/doff. I love these fins, spring strap is excellent. I wear a 8.5/9 in shoes so medium was a great fit. These fins are powerful but dont tax your legs too hard compared to other fins.

Bought these for drysuit dives and I also wanted to try a fin with a spring mount. The fin is not too heavy and helps with keeping feet down. Additionally it is super easy to don - spring stays taught on heel and doesn't move. Lastly, it doesn't take a lot to get moving in these fins. With normal kick power, the fin offers a great amount of propulsion. Got the yellow ones so I can be easily visible.

These fins are awesome for TEC diving. Great for frog kicks and all the modified kicks you would use in SM,CCR, cave and wrench diving. Love the shorter blade that gives tons of power without fatigue. I traded up to these from the my Hollis F1 and am never going back.

Designed in collaboration with the US military and renowned for outstanding performance and reliability, the Apeks RK3 is a rugged thermoplastic rubber fin featuring an over-sized foot pocket to accommodate dry suit boots and a spring strap for easy donning and doffing. The RK3 is available in three sizes of medium, large and super. Apeks didn't give the RK3 fin a shoe size range as this can be very misleading. The environment that an RK3 is used in will tend to dictate the size of fin that you need, for example do you dive in a warm environment wearing wetsuit boots, or are you walking across pebbled beaches and wearing a dry suit and rigid dry boots? Both forms of footwear may be a size 9, but will take up different amounts of space in the fin foot pocket. Therefore, Apeks recommend that you visit your local dive store and try the fins on with your own footwear, just to ensure that you're getting the right fit for your style of diving.
Based on one of the first vented rubber fins sold in North America and popular among military and professional divers. Compact, and ultra-rugged for use in harsh environments. Improved foot pocket with spring straps for ease of use with cold hands or thick gloves. The design has been the standard gear issue fin for military, special ops, coast guard and public safety divers for decades. Short wide blade provides maximum forward thrust while maintaining great maneuverability. Vented blade design reduces resistance on the upstroke and enhances thrust on the downstroke. The vents also eliminate vortexes that can occur along the back of the blade much in the same way split fins eliminate the vortex.
The blade material designed to hold up in the toughest environments, temperatures and abuse. Two large grommet holes designed to fit most carabiners for easy storage of the fins while accessing the dive site. Spring straps as standard, and custom designed buckle holds spring straps in optimum position. Simple push pin design allows simple replacement of springs if necessary. Fins are available in multiple colors. Fin dimensions and weights are as follows: Medium has a blade length of 19.3" (49cm) with an 8.66" (22cm) foot pocket depth, 3.54" (9cm) width and weigh 34.6 oz. (982 g). Large has a blade length of 21.46" (54.5cm) with a 10" (25.5cm) foot pocket depth, 3.74" (9.5cm) width and weigh 42 oz. (1.19kg). Super has a blade length of 22.4" (57cm) with a 10.63" (27cm) foot pocket depth, 3.94" (10cm) width and weigh 45 oz. (1.27kg).
