Pony Bottle for Beginner Divers: An Essential or Superfluous Piece of Equipment?

As a beginner in scuba diving, you're likely faced with a wide range of equipment and accessories to consider. Among them, the pony bottle, also known as a "bailout bottle" or "emergency air supply," often raises questions about its usefulness and relevance for novice divers. In this article, we'll explore the advantages and disadvantages of using a pony bottle for beginners to help you make an informed decision.

What is a Pony Bottle?

A pony bottle is a small compressed air cylinder designed to provide an emergency air source in case of an underwater emergency. It is typically smaller and lighter than a main cylinder, with a reduced air capacity. The pony bottle is connected to the diver's regulator and can be used in case of a failure or issue with the main cylinder.

Advantages for Beginners

Additional Emergency Air Source

One of the main advantages of using a pony bottle for beginners is that it provides an additional emergency air source in case of an emergency. This can be particularly reassuring for novice divers who may feel more secure with an extra air reserve at hand.

Learning Tool

Pony bottles can also be used as a learning tool for beginners. Diving instructors can use them to simulate emergency situations and teach students how to handle them safely and effectively.


Although primarily designed as an emergency air source, pony bottles can also be used for short dives or training exercises, offering some versatility for beginners.

Disadvantages for Beginners

Additional Cost

Acquiring a pony bottle represents an additional cost for beginners, who already need to invest in a complete basic 

equipment set. This can be a deterrent for some novice divers with a limited budget.

Weight and Bulk

Pony bottles, although lighter than main cylinders, still add extra weight and bulk to the diver's equipment. This can make diving more challenging for beginners who are already getting used to the basic gear.

Risk of Overconfidence

Using a pony bottle can also give beginners a false sense of security and lead them to take inconsiderate risks, thinking they have an extra air reserve at their disposal.

Recommendations for Beginners

While using a pony bottle is not mandatory for beginners, it can be recommended in certain situations, including:

Cold Water or Deep Dives

For cold water or deep dives, where air consumption is generally higher, a pony bottle can provide additional safety.

Dives with Increased Risk

If diving conditions present an increased risk, such as strong currents or reduced visibility, a pony bottle can be an additional asset for beginners.

Instructor's Recommendation

In some cases, the diving instructor may recommend using a pony bottle for beginners, depending on their skill level and specific diving conditions.

Ultimately, the decision to use a pony bottle as a beginner will depend on your personal preferences, budget, and your diving instructor's recommendations. Regardless of your decision, always follow safety guidelines and never exceed your limits as a novice diver.
