AquaLung Compact Retractor Kit For BCD 
Rob Allen X-Blade Knife Sheath Aqualung Axiom i3 Original BCD Size Chart
How to measure your BCD
- Waist: measure at the waistline shown in the diagram, rather than using the size on your jeans. Keep the tape level.
- Over the shoulder (OTS): run the tape from your waistline at the back, over one shoulder, to your waistline at the front.
- Check the BCD over the exposure suit and layers you will dive in. Adjust the shoulder and waist straps, then check that you can breathe and move comfortably with the BCD inflated.
- Use the chart for the exact BCD model. Height and weight are guides; waist and harness fit also matter.
If you are between sizes, contact Dive Gear Australia with your height, weight, waist and shoulder measurements, plus the suit you plan to wear.

Body measurements are in centimetres (cm); weight is in kilograms (kg). These are approximate fit ranges for this older BCD model. Check the fit over your diving suit.

Use this chart for the original Axiom i3. The Axiom i3+ has a separate guide.

Aqualung Axiom i3 BC
The Aqualung Axiom i3 BC is Aqualungs most comfortable, and easy-to-use BCD ever made. It is a feature-rich BC, Advanced style, wrap-around jacket that incorporates the innovative i3 inflation/deflation system.
The integrated Wrapture™(patented) harness system allows you to stand up straight in total comfort while the cylinder remains perfectly vertical and pulled in close. Diving has never been this comfortable.
Aqualung Axiom i3 BC Features:
- The GripLock™ tank band and buckle system is a strong, secure system that comes standard on the Axiom i3. This robust and simple system secures a safe bottle. Gone are the days of complicated web weaving and you don’t have to worry about pinching your fingers with the innovative finger-saver feature.
- The Wrapture harness system, using the shoulder swivel buckles (patented) and a customized mini-backpack, provides comfort and stability while preventing “ride-up” at the surface
- The i3 Control System (patented) provides single-touch control for inflation and deflation
- The low profile flat e-valves (patented) all open simultaneously when the i3 lever is depressed
- The GripLock tank band and buckle system provide security and easy change out of cylinders
- Technologically advanced ResisteK material resists fading and abrasion
- SureLock™ II weight pouches (patented) provide a simple, single-pull release. Loading is as simple as inserting and “clicking”
- Pull down oral inflator is easy to deploy, use and stow
- A bladder retraction system is used to pull in the sides of the bladder during deflation
- An adjustable chest strap can be raised or lowered on a rail system
- A scooped octo-pocket on the top, front of the right lobe makes it easy to stow and deploy an octopus. The octopus remains visible and accessible throughout the dive
- Some divers may find it useful to run their instruments behind the left pocket and out the scooped opening on the top front of the lobe
- Pocket within a pocket – A small security pocket is found on the flap of a larger drop-down pocket
- Knife attachment points are found on the left lobe
- Features 5 stainless steel D-rings and 2 plastic D-rings for all of your accessories
- Right shoulder pull dump
- Rolled neck collar for comfort
