Q: What is the capacity of a small portable oxygen tank for diving?

A: Small portable oxygen tanks for diving typically hold 1-6 cubic feet of compressed oxygen, designed for short-duration dives or emergency use. They are lightweight and ideal for snorkelers or shallow divers needing backup air.

Q: How long does a small portable scuba tank last underwater?

A: A small portable scuba tank lasts 10-30 minutes, depending on depth and breathing rate. Shallow dives at 10-15 feet maximize usage time, while deeper dives consume air faster.

Q: Are portable oxygen tanks safe for recreational diving?

A: Yes, when used as a secondary air source or for surface emergencies. However, they shouldn't replace standard scuba tanks for prolonged deep dives due to limited capacity.

Q: Can portable oxygen tank diving equipment be refilled?

A: Most portable tanks are refillable using standard scuba compressors. Always check manufacturer guidelines and pressure ratings to ensure safe refilling procedures.

Q: What's the difference between a small portable scuba tank and standard dive tanks?

A: Portable tanks are 50-90% smaller in capacity (1-6 cu ft vs 80+ cu ft), weighing under 5 lbs. They're designed for emergencies or surface use, not extended underwater exploration.
