Atomic Aquatics BC2 BCD with SS1 Safe Second Inflator

Experience premium comfort, streamlined performance and dependable backup breathing with the Atomic Aquatics BC2 BCD with SS1 Safe Second Inflator. This advanced scuba diving package combines Atomic Aquatics’ high-performance back-inflation BCD with the integrated SS1 alternate air source and power inflator.

The BC2 uses an exceptionally tough double-laminated, polyurethane-coated fabric that resists abrasion, punctures and tearing. Unlike conventional nylon BCD materials, its waterproof exterior sheds water rapidly after surfacing, helping the BC2 dry faster and absorb less water during transport.

Its back-inflation design positions buoyancy behind the diver, supporting a streamlined profile and comfortable horizontal trim underwater. A quilted back pad, adjustable lumbar support, rigid backpack and secure CAM-LOK tank band combine to deliver excellent comfort and cylinder stability.

Included in this package is the Atomic Aquatics SS1 Safe Second Inflator. This premium unit combines BCD inflation, deflation and alternate-air-source functions in one compact device. It reduces hose clutter while giving the diver immediate access to a reliable backup regulator during an air-sharing emergency.

Why Choose the BC2 with SS1?

Pairing the BC2 with the SS1 creates a highly integrated scuba diving system. Instead of carrying a separate octopus regulator on an additional hose, the SS1 serves as both the BCD inflator and the diver’s backup second stage.

During an air-sharing emergency, the diver donates their primary regulator to their buddy and breathes from the SS1. This configuration allows the donating diver to retain direct control of their buoyancy while providing their buddy with the longer primary regulator hose.

BC2 Features and Benefits

Advanced Back-Inflation Design

The BC2’s air cell sits behind the diver rather than wrapping around the torso. This leaves the chest and sides feeling less restricted while encouraging a balanced, horizontal position underwater.

Benefits:

• Improves underwater streamlining
• Reduces drag while swimming
• Provides greater freedom around the chest and shoulders
• Supports comfortable horizontal trim
• Avoids the squeezing sensation associated with some jacket-style BCDs

Exclusive Waterproof Fabric

The BC2 is manufactured from a custom double-laminated, polyurethane-coated material. According to Atomic Aquatics, it holds nearly twice the pressure of standard BC materials while offering exceptional resistance to abrasion, tears and punctures.

The matte exterior is also UV-resistant, stain-resistant and resistant to chemicals, mould, rot and mildew.

Benefits:

• Exceptional durability for frequent diving
• Sheds water quickly after surfacing
• Absorbs less water for easier transport
• Dries faster between dives
• Easier to clean than traditional woven fabrics
• Maintains its premium appearance over time

Patented EZ-LOK Integrated Weight System

The Atomic Aquatics EZ-LOK system makes loading, securing and releasing dive weights fast and intuitive. Each zippered weight pouch slides beneath the arms and locks into place with a reassuring snap.

A simple one-handed pull releases the weight pouch when required. Rear anchoring helps prevent the pouches from shifting forward during the dive.

Benefits:

• Fast and secure weight installation
• Accepts hard or soft dive weights
• Audible and tactile confirmation when locked
• Simple one-handed emergency release
• Helps prevent uncomfortable forward weight movement

Each standard pouch can hold up to approximately 4.5 kg, while the Extra Large BC2 pouches can carry up to approximately 6.4 kg each.

Ratcheting CAM-LOK Tank Band

The BC2 replaces conventional woven tank-band webbing with Atomic Aquatics’ ratcheting CAM-LOK system. Similar to the closure used on ski boots, it adjusts quickly to accommodate various scuba-cylinder diameters.

The polyurethane-coated one-piece band does not absorb water, stretch or require soaking before use.

Benefits:

• Faster cylinder installation
• No complicated webbing to thread
• Adjusts easily to different tank sizes
• Resists stretching and slipping
• Does not absorb water
• Provides secure cylinder retention

Quilted Back Pad and Adjustable Lumbar Support

A padded diamond-pattern back panel cushions the diver’s back, while the adjustable lumbar pad can be positioned for personalised support. The carrying handle is discreetly integrated behind the back pad.

Benefits:

• Improves comfort with a fully loaded scuba cylinder
• Helps distribute weight across the back
• Provides adjustable lower-back support
• Makes the BC2 comfortable during extended dives

Low-Profile Trim-Weight Pockets

Two streamlined rear trim pockets help distribute weight around the cylinder and improve the diver’s underwater balance. Each pocket accommodates up to approximately 2.3 kg.

Benefits:

• Helps achieve a more horizontal diving position
• Reduces the amount of weight carried around the waist
• Improves balance and stability
• Maintains the BC2’s hydrodynamic profile

Titanium-Coated Stainless-Steel D-Rings

Strategically positioned D-rings are manufactured from corrosion-resistant 316 stainless steel and finished with a titanium PVD coating.

Benefits:

• Secure attachment points for accessories
• Excellent corrosion resistance
• Strong and durable construction
• Premium appearance that complements the BC2

Sand-Resistant Pocket Zippers

The BC2’s self-sealing zippers close completely, helping prevent sand and debris from becoming trapped between conventional exposed zipper teeth.

Benefits:

• Smooth and dependable operation
• Reduces problems caused by sand contamination
• Helps protect stored accessories
• Easier to rinse and maintain

Dry Glide Exhaust Valves

Low-friction 316 stainless-steel pull dumps are positioned for convenient buoyancy adjustment. Anti-floating pull knobs are designed to remain easy to locate without drifting awkwardly around the BCD.

Benefits:

• Smooth and controlled air release
• Convenient access in different diving positions
• Corrosion-resistant internal components
• Easier to locate by touch

Atomic Aquatics SS1 Safe Second Inflator

The included Atomic Aquatics SS1 combines three important functions in a single compact unit:

• Power inflation
• Oral inflation and deflation
• Backup regulator breathing

Unlike many traditional combination inflators, the SS1 is designed to deliver dependable breathing performance as a genuine alternate second stage. Its large controls are easy to identify and operate, including while wearing dive gloves.

Key internal components are available in corrosion-resistant stainless steel, creating a durable and serviceable unit designed for long-term use.

SS1 Features and Benefits

• Integrated safe second: Provides a readily accessible backup regulator for air-sharing emergencies.
• Power inflator functionality: Allows controlled pneumatic inflation of the BC2.
• Oral inflation and deflation: Supports manual buoyancy control when required.
• Reduced hose clutter: Eliminates the need for a conventional octopus on a separate hose.
• Large, easy-to-use controls: Designed for simple operation with or without gloves.
• High-flow quick disconnect: Supports the airflow required for regulator breathing.
• Corrosion-resistant metal components: Built for dependable performance in demanding saltwater environments.
• Serviceable construction: Designed for maintenance and long-term ownership.
• Integrated buoyancy control: Allows the donating diver to control the BCD while breathing from the SS1.

How to Share Air with the SS1

Because the SS1 is attached to the shorter corrugated BCD hose, the correct air-sharing procedure differs from using a conventional octopus.

In an out-of-air situation:

1. Donate your primary regulator to your buddy.
2. Begin breathing from your own SS1.
3. Maintain control of both divers and manage your buoyancy using the SS1.
4. Begin a controlled ascent according to your training.

Divers should receive appropriate instruction and regularly practise this procedure with their buddy.
