For deep or deep technical diving or wreck diving 30 and 40 cu ft (5 litre and 7 litre) cylinders are often used. The pony bottle is a basic requirement for low risk solo diving if the dive is too deep for a safe free ascent, as there is no source of emergency air from a buddy.
How long does a pony bottle last?
The duration of breathing gas you get from a small bailout bottle will depend on your breathing rate. Manufacturers claim 114 breaths or 6 to 10 minutes at the surface for an average person using the 6-cubic-foot (0.2-cubic-meter) model.
How many breaths does a pony bottle have?
With 3.0 cubic feet of air, your Spare Air pony bottle gives you approximately 57 surface breaths (actual breaths vary by individual and depth). It’s easy to refill your Spare Air from a full 3000 psi scuba tank using the refill adapter included with every unit.
How long does a pony scuba tank last?
At a SAC rate of 1.0 (not unheard of in an emergency situation), a 4 c.f. bottle will last about 2 min at 30 feet (10 meters). That’s not a lot of time to sort through an emergency that may come up and make a safe ascent. It’s even less time if you decide to dive deeper than 10 meters.
Should I dive with a pony bottle? – Related Questions
What size pony bottle should I get?
Probably the most useful overall size for what you’re describing is a 19 cft. Anything smaller than a 13 is probably not worth carrying, and anything larger than a 19 is getting to be a stage bottle. But it might be worth it to really examine why you feel the need to carry redundant air.
Is it OK to leave SCUBA tanks full?
Do not store tanks that are full of air for prolonged periods of time (no more than 3 months. A tank should be stored with just enough pressure (200 psi) to keep moisture out. Remember the higher the tank pressure, the greater the corrosion that may form inside.
How long does a mini scuba tank last?

Do mini SCUBA tanks work?

How long does a 3000 psi scuba tank last?
Ultimately, most divers will find that a standard rental tank of 3,000 PSI will last 45 to 60 minutes during a dive at the depth of 30 feet. With greater fitness and lower breathing rates, time underwater will increase. Meanwhile, more exertion and diving at greater depth will cause your time underwater to decrease.
Should SCUBA tanks be filled with 100% oxygen?
For dives deeper than 66 m the gas mixture should contain less than 21% oxygen to avoid the risk of acute oxygen toxicity.
Can you leave SCUBA tanks in car overnight?
Heat will cause the breathing gas inside the tank to expand, increasing the pressure. It’s recommended that the tanks are in a compartment with open air circulation. Tanks should not be stored in a car during hot weather or any time there is a possibility of excessive temperatures where the tanks are stored.
At what PSI should you end a dive?
Always end the dive with at least 500 psi remaining in your tank. This statement is uttered during practically every pre-dive briefing in locations all over the world. The rationale behind it is solid; divers should plan their dives well and monitor their gauges carefully to avoid running low on — or out of — air.
Should you inhale or exhale when diving?

How deep can I dive without decompression?
How deep can you dive without decompression? Practically speaking, you can make no stop dives to 130 feet. While you can, in theory, go deeper than that and stay within no stop limits, the no stop times are so short that “well within” limits is essentially impossible.
How deep does a Navy SEAL dive?
Navy SEALS commonly don’t need to be in extremely deep water for their work. But with how extensive their training is in diving, they are likely to be certified to dive 100-130 feet or deeper with many technical certifications on top of that.
What is the safest depth to scuba dive?
The main reason why the recreational diving depth limit is 40 meters/130 feet is safety. Yes, you can exceed this point, but you need technical diving skills to do that. Beyond 40 meters/130 feet, it is necessary to make decompression stops and even use different gas mixtures, depending on the depth you reached.
