A compact scuba tank for short dives and training, designed to supply a brief, travel-friendly air reserve, the cypreason Scuba Tank. Learners and experienced divers who want a portable backup will value the lightweight construction and separable regulator. Will the 0.5-litre capacity meet practical needs for practice or emergency use?
⚡ At a Glance
- • Air Capacity: 0.5 litres, tested to support about 6-12 minutes breathing at 15 ft and 50°F
- • Best for: Novice divers for practice, snorkellers refining skills, and experienced divers needing a compact backup
- • Not ideal for: Primary supply on extended or deep technical dives where longer duration is required
Half-litre aluminium cylinder rated to 3000Psi with a separable regulator and travel-friendly weight. Short-duration breathing for practice or emergency backup, with depth guidance for training and backup use.
Portable practice and travel, with 0.5-litre capacity
A 0.5-litre cylinder, tested at 15 feet and 50°F, supports roughly 6-12 minutes of breathing; the regulator separates from the tank and the unit weighs 2.38 lbs when handled. The separation reduces bulk for carrying and simplifies packing for trips, including taking the tank on a plane according to the description.
Quick practice sessions and straightforward transport for shore trips or pool drills. A compact reserve is easy to carry when space is limited.
Corrosion-resistant construction, with 6061 aviation aluminium
Cylinder body is made from 6061 aviation aluminium, a grade noted for strength and resistance to seawater corrosion; regulator components include a pressure gauge, mouthpiece, inflation port, pressure relief valve and explosion-proof valve. The accessory kit also includes replacement parts and is described for two years of normal use.
Reduced corrosion risk helps keep the tank serviceable in marine environments. Durable materials and spare parts support repeated training or backup use.
Refill flexibility and safety monitoring, with 8mm inflation interface
Working pressure is 3000Psi and the inflation interface measures 8mm, allowing inflation via an air compressor, scuba adapter or hand pump capable of at least 3000Psi; the regulator includes a pressure gauge and safety valves to monitor and relieve excess pressure. Extra replacement parts come in the accessory kit for routine upkeep.
Refilling at shore or in a workshop is straightforward when compatible equipment is available. Pressure readouts and relief valves help manage safety during use.
✨ The 4 Key Reasons for cypreason Scuba Tank
- Aviation-grade aluminium - Resists seawater corrosion and keeps tank serviceable for longer
- Separable regulator - Allows easy carriage and plane travel when regulator is removed
- 3000Psi working pressure - Compatible with compressors, hand pumps and scuba adapters for refills
- Safety valves and gauge - Provides clear pressure feedback and automatic relief under fault conditions

❓ Frequently Asked Questions
Q: How long will a full cylinder let me breathe underwater?
A: Tests recorded about 6-12 minutes of breathing at 15 feet and 50°F, though actual duration varies by user and conditions.
Q: Can the cylinder be used as a backup for experienced divers?
A: The description specifies the cylinder can serve as a backup air source for experienced divers and cites a usable depth up to 100 feet when used that way.
Q: How do I refill the tank and what fittings are needed?
A: The inflation interface is 8mm and the working pressure is 3000Psi, so refilling can be done with a compatible air compressor, scuba adapter or a hand pump capable of at least 3000Psi; extra spare parts are supplied in the accessory kit.
🏆 Our Verdict
Suitable for learners practising in pools or shallow open water and for experienced divers who want a compact backup air source. The combination of a half-litre 6061 aviation aluminium cylinder, separable regulator and safety valves makes a robust short-duration reserve. Weigh up upfront cost against occasional use, as corrosion resistance and included spare parts point to solid long-term value.
