At first glance our 2008 advanced Eagle Z1 BCD design could be easily confused with a back floatation or wing type of BCD.
Our advanced designs when used correctly will NOT force a diver in a face down horizontal position  at the surface! 
Our Eagle Z1 series of buoyancy compensator devices are NOT a typical back floatation wing types, and  they DO NOT perform like one at the surface!

PROBLEM:  INCORRECT CENTER OF GRAVITY, NO ADJUSTMENTS = HIGH DRAG NOSE UP ATTITUDE.

SUPERIOR BALANCE
You really can kick and glide with our BCD's, and improve your air consumption up to 15% verses a standard jacket style BCD with wt. belt. Our design provides extremely stable roll & pitch control, a delightful method of travel. The buoyancy air cell is properly located very close to your back, and the integrated weight system is correctly located and centered on your hips. With most other designs the diver moves through the water inefficiently with a 15 degree to 30 degree nose up swimming position wasting massive amounts of energy and valuable air.
SUPERIOR HARNESS
Our harness is built directly into the air cell protector. This eliminates the droopy cylinder, and the side to side tank rocking. Our automatic depth compensating  harness is extremely comfortable and does not require constant adjustments during the dive. Anatomically correct offering unequalled freedom of movement.
SUPERIOR AIR CELL
Loss of buoyancy control is always serious. Using cheaper lightweight easy to puncture air cells may save you money, but not your life. Eagle Z1 models DO NOT utilize the substandard "Pop & Drop" bladder-less air cell technology that is impossible to repair.

SOLUTION: 3 AXIS ADJUSTMENT
PERFECT CENTER OF GRAVITY & LOW DRAG & AFFORDABLE PRICE!

1960's / CHEST MOUNT: The oldest design. Designed to support an unconscious diver in a belly up / head up position. Very uncomfortable, and very unstable when used for scuba use. These models require the use of a uncomfortable weight belt, a backpack, and unforgiving crotch strap.

1970's / BACK MOUNT: Excellent stability underwater, but very little support or stability at surface. Most required the use of a very uncomfortable weight belt & unforgiving crotch strap. Not accepted by some sport diving certification agencies. Still in use for professional cave diving.

1980's / JACKET STYLE: The 1980's designed jacket style wraps the air cell around both the front and back of the upper torso. Very bulky, high drag, and not comfortable, but offered good surface support for novice divers. Poor design and serious quality control issues were common.

1990's / WT. INTEGRATED: The concept of canceling the forces of positive buoyancy and negative ballast weights. Soon became the most popular version because it provided more comfort and convince. Many versions, some were acceptable, and others were dangerous with bad wt. design.

2000's / MODIFIED WT. INTEGRATED: This is the time period when most of the major BCD producers decided the existing products with internal bladders had too long of a life span. In an effort to cut cost and increase profits they invented the bladder-less BCD material. This is also known as "Pop and Drop" because it tears easy and the divers drops like a stone. This new design is much less labor intensive to produce, and has a much shorter life span. Another serious problem is this lightweight fabric cannot be repaired if punctured, the whole BCD must be replaced further increasing sales.

2005 / EAGLE Z1 BCD: Our designers took all the best functional features of each type of pre-existing buoyancy device, combined them, and seriously refined them. The result is the surface support of a jacket, the comfort of a weight integrated, and the stability and low drag of a back mount. All our Eagle Z1 models will reduce fatigue, feel safer, consume less air, be far more comfortable, travel lighter, and last longer. Click here to see the future in BCD design
