The Aqua Lung Dimension i3 is a special back inflation bcd for several reasons. First, let’s talk about the wrapture harness system. This bc uses patented swivel shoulder buckles as well as a proprietary, uber-thin backplate in order to achieve next level comfort and stability.
Furthemore, the design of this wrapture system limits how much the BC rides up when you’re on the surface – a well known downside of back inflation bcds. Honestly, we did find it to still ride up a little on the water’s surface – but considerably less than most other back inflate bcds.
Out of the water, the wrapture keeps the air cylinder close to one’s centre of gravity, transferring the weight to your hips. This makes the cylinder perfectly vertical, meaning it’s easy to stand upright!
Next, the patented i3 control system means you can inflate and deflate the BC with just one touch. This eliminates the need for the traditional inflator that dangles, sometimes annoyingly, at the end of a corrugated hose. It’s simple and easy to use – just lift up on the lever to inflate and push down to dump air.
Third, the patented Surelock II Mechanical Weight Release System, provides a single pull release for maximum safety. Inserting weights is easy and then they’re secure – only being released, when you pull the handle.
There’s also a bladder retraction system that’s used to pull in the sides of the bladder during deflation, keeping the unit steamlined and reducing drag considerably.
With 4 stainless steel D-rings, a security pocket attached to a larger drop down pocket and various knife attachment points, it’s easy to keep your additional gear safe, secure and organised whilst diving with this bcd.
All these features come together to form a truly awesome buoyancy control device which is why the Aqua Lung Dimension i3 is, in our opinion, the very best back inflation bcd trending the market right now.
