Atomic Aquatics X1 BladeFin



Atomic Aquatics X1 BladeFin

Atomic Aquatics X1 BladeFin is a high-performance Atomic Aquatics fin at a moderate price. Atomic SplitFins have a flexible blade designed for ease and efficiency of kicking. The BladeFins are designed for power and speed with a moderately firm blade. New X1 BladeFins are designed with a firmer blade for ultimate power general purpose diving, tech diving, extreme applications and alternate kicking styles.

Why X1 BladeFins?

Atomic has maximized every kick for more thrust when compared against most plastic fins and any split fin or hinge style fin. Maximize every dollar for great value.

  • Firmer, shorter blade design to maximize kicking power.
  • Solid internal frame delivers more control.
  • Maneuverability for tight spaces.
  • Perfect for general purpose diving, tech diving and extreme applications.
  • Great for alternate kicking with a flutter kick and the occasional frog kick.  This fin is not suitable for cave, technical or dir based diving, as it is incapable of doing a proper helicopter turn or back kick.

X1 BladeFin Design
Legendary Atomic Aquatics design and quality.

1. Rigid Low-Profile Side Rails and Shorter, Stiffer Blade
Makes turning and pivoting easier. Most fins have taller side rails for tracking and bending strength. The Atomic X1 BladeFin has lower profile rails with less side-to-side resistance that allow you to rotate, spin and turn more efficiently during alternate fin kicks.

2. Monocoque Structure and Power Plate
Unique structural engineering design is connected to the low-profile rails, efficiently transferring power from the leg and foot to the rails.

3. Asymmetrical Blade Bend Flexing
This design attribute is perfect for alternate kicking styles. Scissor kicks, frog-kicking and helicopter turning in tight circles put more emphasis on the up-kick or return stroke. For these kick styles, the X1 provides more feel and control of the fin to maneuver more effectively without folding under heavy load.

4. Vertical Stabilizers or Strakes
Adds stability and lowers drag to keep the fin tracking straight as an arrow. Other fin designs use taller side rails to keep the fin tracking straight. By using strakes to straighten the fin, the X1 BladeFin does not add significant side drag like tall side rails.

X1 BladeFin Kicking Styles
Optimal performance for general purpose diving and alternate kicking styles.

The X1 BladeFin has the backbone to control and maneuver in tight spaces, perfect for alternate kicking styles such as helicopter, scissors, backwards, flutter and frog-kicks. Another design attribute of the X1 BladeFin that contributes to improved alternate kicking styles is asymmetrical blade bend flexing which provides more feel and control of the fin to maneuver more effectively without folding.

EZ-LOK Buckle System
Easily snap the buckle on and off. And be confident that it will not release accidentally. Buckles rotate 180 degrees and straps adjust with a simple pull. Standard on all X1 BladeFins.

Taller Foot Pocket Design
The X1 BladeFin foot pocket design is taller with low-friction entry sections inside the pocket, perfect for large boots and drysuit boots.

Warranty & Care
Atomic Aquatics fins are warranted against defects for a period of one year. Keep out of direct sunlight when possible to avoid color fading. Store your fins with the foot pocket inserts in place and in a manner that prevents deforming.
