Apeks RK3 Fins Review & Test

These reliable fins feel comfortable in a trim position. They first caught my attention when I heard that RK3 Fins are the go-to for Special Ops & the Military.

Some people may not think that fins do that much to help with deep dives and swimming, however, they’d be wrong!  You always need a good pair of fins to make sure you cut through water with plenty of power and precision.

But how well does this pair actually hold up?  

We tried them on for size, and in the water, to find out.

The RK3 fins are some of the best-performing accessories of their kind online, which, given the fact there’s so much choice around, is definitely a good thing.  If you’re looking for a solid pair of fins that give you plenty of control on a budget, they might just be the perfect fit for you.

Perfect For: Professionals such as Public Safety Officers, Every Day Dive Professionals & those that dive in harsh environments.

Unboxing the RK3 Fins

Right away, you can tell that this is a tough pair of fins.  That’s not always a bad thing!  In fact, you may want to strap on a pair of thick fins if you struggle to cut through the water.  The manufacturer says that these fins are inspired by some of the original rubber models sold in the US.  As the saying goes, if it ain’t broke, don’t fix it.

I have done the hard work, now for the easy bit. Check out the best prices that I have found on Amazon here.

The fins come in black or white, which means anyone less fussy about the look can make an easy choice.  Spring straps seem to make things easy to handle, especially when you want to get in and out at short notice.

However, we can’t just judge these fins on looks alone!  Therefore, we made a point of checking out their performance out in the current.

There’s a lot more to take into consideration that I initially thought, find the best budget, best pro and best for newbies.


Good in Tough Conditions

These fins are reportedly preferred by professional divers, and that’s probably because they’re a solid fit, and are well ventilated.  That means they’re never too tough to manoeuvre, and they actually make for a pretty comfortable swim in faster currents.

Easy to Get On & Off

Some fins are a nightmare to handle on and off.  The spring straps here make things really simple even when you’re in the thick of it.  That’s great news for anyone who’s had to fumble around getting fins off at short notice.

Rugged & Robust

These are classic fins.  Therefore, they may not be as fancy as some of the newer, more streamlined ones out there, but they are perfect for withstanding a lot of pressure.  They will stick by you as long as you need them to.  It’s always good to have some toughness in the fins, though flexibility is great, too.  You get lots of propulsion and control here.
