How Atomic Aquatics SplitFins Work? SplitFin Wings “Slice” Through the Water. Traditional paddle fins work by pushing water rearward. As a paddle fin is pushed through the water, much of the water spills over the top surface of the blade and sticks to it, creating drag. Extra kicking effort is required to overcome that drag. The Atomic SplitFin slices through the water with two wing-shaped surfaces, creating lift and forward propulsion more like a propeller. Any water traveling over the top of the blade is funneled into and out of the opening (split) between the wings. Drag is reduced, effort is reduced, and efficiency is increased. Propeller-Fin™ Technology Moves You Faster Atomic Aquatics SplitFins use Propeller-Fin Technology to deliver ultra-high speeds with a small-range rapid flutter kick. This works in the same manner that increasing the RPM on a boat propeller accelerates a boat to high speeds. Multi-Composite Plastics And Other Uniquely Atomic Features The Atomic signature is our use of exotic materials specifically designed to improve performance. We developed multi-composite plastics for the SplitFins to maximize the efficiency of the kick with less fatigue. Flexible side rails and a stiff foot pocket are combined with stiff battens in the blade to control the flex pattern for optimum performance. Our patented EZ-LOK Buckle System is one of those distinct Atomic features that make divers love us even more. The Universal Spring Straps share the same features found on Atomic Springs, but are made to fit almost any other brand of open heel fins. Available in medium and long.

    ... these fins now for almost two years andI absolutely love them. From the first time I got in ...

    Posted by Sidney O. Smith Jr. on Oct 31st 2018

    I have had these fins now for almost two years andI absolutely love them. From the first time I got in the water with them to this day I couldn't image using any other fin. I feel I get more power per kick, I use less air, and with the added spring straps they are a breeze to get on and off. I don't even notice I'm wearing them while diving, The one thing I would note is the strap posts are a non standard size. If you need replacement straps or you want to go with spring straps you have to get Atomic specific ones. Not a big deal because they are priced the same as the others, but if you are traveling and you break a strap you better hope there is an Atomic dealer close buy if you don't carry spares with you. In short carry spares.... If your on the fence about getting these jump off and give them a try you won't regret it.

    Best fins in 40 years of diving.

    Posted by John M. Kohler on Oct 31st 2018

    These are the best power to weight ratio fins I've used in 40 years of diving, and I've owned a lot of the classic and more advanced recent fin designs. Power and flexibility with every kick, very handy fins to put on in a crowded dive boat, and easy to take off near the ladder. The colors are also more vivid than the photos suggest, which make them fun to photograph in bright tropical waters and also make them great for finding your dive buddy in murky low visibility water. Highly Recommended.

    Love this fins, though it's probably too big for my height (153cm). I need good effort to kick in water.

    The Best

    Posted by Travis Danley on Oct 31st 2018

    The Best fins I have used, after using the split fins I am hooked, I thought since it has been so long since I have used other fins that I was just a name brand person myself, but after a recent dive trip to Utila Honduras I used the shops fins, and man did I miss my Atomics.. You do get what you pay for. if you don't get the Atomic's, at least get the spring stap.. it is a must

    I hardly noticed that they were even on when in the water and am super excited about reducing the possibility of leg cramps in .

    Posted by Stephanie on Oct 31st 2018

    Took these to key west. I get cramps a lot in my Cressies and was looking for a split fin to try and cut down on the debilitating and time draining cramping while diving. Most of the fin that initially attracted me were shorter so I was unsure with the length on these which is similar to my existing fins. Based on the reviews on different sites I decided to give these a try and although we did have some drift I did notice a big difference and did not cramp up at all. I hardly noticed that they were even on when in the water and am super excited about reducing the possibility of leg cramps in the future now that I have these bad boys. They are expensive but you get what you pay for and in this case I feel the investment was well worth it. I also saved on the manufacturer advertised price so in my mind this was a win win. I would recommend these to other divers with similar leg cramping issues.

    Exactly what i wanted. Fit just right. I am a size 10, but I ordered a size 9 (5mm) booty and L fins. Everything worked perfect.

    Finally getting rid of my foot bannanas

    Posted by David S. Wilson on Oct 31st 2018

    I've been envying my son's and daughter-in-law's fins for too long! Mine were OK, but they've warped pretty badly over the past few years and even though I've tried everything to straighten them out, it hasn't worked. The Atomic Aquatics split fins don't seem to warp even after months of storage in a flexed position and they are very efficient in terms of the amount of effort required to produce useful thrust.
