Atomic Aquatics Ti2 Titanium Scuba Diving Octopus
The Ti2 Octopus combines titanium components with automatic flow control in an alternate air source. Its yellow cover helps identification, while the seat-saving design reduces pressure on the valve seat when the regulator is stored without pressure.
Features and benefits
- Balanced second stage. Pneumatic balancing reduces the force needed to open the demand valve, helping the second stage respond smoothly as you inhale.
- Automatic Flow Control. AFC changes the Venturi assistance as depth changes, reducing the need for manual flow adjustment. The Rapid Adjustment Knob provides additional control for handling and specific diving situations.
- Titanium valve components. Titanium combines low weight with resistance to seawater corrosion in the second-stage mechanism, making it useful for regular saltwater diving.
- Seat-saving design. When the regulator is depressurised, the dynamic orifice lifts away from the low-pressure seat. This reduces prolonged loading on the seat during storage.
- Visible alternate air source. The yellow hose and cover make the octopus easier to distinguish from your primary regulator when locating and deploying it.
- Compact fixed hose connection. The non-swivel connection and low-profile exhaust keep the alternate second stage compact for stowage.
- Long alternate-air hose. The supplied hose gives the receiving diver room to position the second stage during air sharing.
Setup and compatibility
Use as an alternate second stage in a compatible regulator system, with hose routing and stowage matched to your training and equipment.
Care, rinsing and storage
Clean this component as part of a complete, correctly assembled regulator system. After each dive, connect the assembled regulator to a scuba cylinder and open the valve to pressurise the system. Keep it pressurised while fully submerging the first stage, second stages and connected hoses in fresh water. This allows thorough cleaning of the exposed components and hoses while helping prevent water entering the internal air passages, where it can cause corrosion and damage. Keep the cylinder secure throughout cleaning.
For routine cleaning, Dive Gear Australia recommends Cressi Neoclean Wetsuit Wash Neoprene Cleaner 500 mL or Revivex Wetsuit Shampoo 10 oz to help remove salt, chlorine and everyday residue. Dilute according to the cleaner’s label, then rinse thoroughly with fresh water.
Keep the regulator pressurised throughout washing and rinsing. Lift it out of the water and dry the first stage and cylinder connection before closing the cylinder valve, releasing the pressure and disconnecting. Fit the clean, dry dust cap, then allow the regulator to dry in the shade. Store it with the hoses loosely curved, without sharp bends or tension.
Before each dive, inspect the mouthpiece, hoses and connections for wear or damage. Have your regulator serviced by an authorised Atomic Aquatics technician at the interval specified in its manual, or sooner if it leaks, is damaged or its breathing performance changes. Leave internal adjustments and repairs to a qualified technician.
