Apeks Fins Rk3
The RK3 fin design has been the standard for Military, Special Ops, Coast Guard, and Public Safety Divers for decades. It is a traditional all rubber design. The RK3 blade material is formulated to hold up in the toughest environments, temperatures, and abuse. The short wide blade provides maximum forward thrust while maintaining great maneuverability. The vented blade design reduces resistance on the upstroke and enhances thrust on the downstroke. The fins come standard with stainless steel spring straps.
The Apeks RK3 HD is the latest model in the RK3 range. It is made from a higher density (HD) than the standard RK3, which makes the fin stiffer and with negative buoyancy, ideal for wetsuit diving. The Apeks RK3 HD is a rugged thermoplastic rubber fin featuring an over-sized foot pocket to accommodate drysuit boots and a spring strap for easy donning and doffing. The RK3 HD is available in four sizes: Small, Medium, Large and Super. We did not give the RK3 HD fin a shoe size range as this can be very misleading. The environment that an RK3 HD 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 drysuit 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.

Great reviews from my fellow Coast Guard divers.

The Apeks Fins Rk3 are Neutrally Buoyant!!! I have been searching for a neutral buoyant fin and this is it. I have discarded my heavy tech fins.
Thank you for the review on the Apeks Fins Rk3 . If there is anything else we can do for you please let us know. Thanks again

Great fins. Neutrally Bouyant in fresh water (they float ever so lightly) Good power for being a shorter fin, which means you're less likely to kick coral/sponges if you're a not so spacially aware scuba diver. Otherwise these are great for calm dives with a moderate to no current. Solid single piece mold with an exceptional spring back strap. My go to fin for all my dives. I only wish Apeks would put them out in a Blue color as well. 10/10 would buy again if I ever lost them. Otherwise I don't see them breaking or otherwise going inop on me like other plastic/rubber hybrid fins do.
Hi Rob,

Looking forward to having RK3's. They're amazing for making minute adjustments, and still have power. They're best used while frog kicking (or modified frog kicking). Very excited!

I tried a set of MK3s on a recent trip to Roatán. My wife hated my black fins that I had prior, as they were hard to spot. I haven’t been diving with these new fins, but I can’t wait to see them pop underwater!
Thank you for the great feed back
