The most convenient spare air cylinder tank that you refill, not the dive shop.

This is one of the smallest portable air sources available and is refillable from your own scuba tank. The Spare Air emergency air supply gives peace of mind when there is no room for error.

Why use a Hotdive spare air source cylinder?

A spare air source should be a standard piece of scuba diving equipment for every safety-minded diver. Hotdive mini tank is the preferred choice for professional and sports divers, and for a very good reason; it saves lives. This has been proven to be faster than buddy breathing and easier than an octopus.

Even if you never need to use it, it’s always there as your backup. Hotdive mini-tank cylinders will provide a limited number of breaths for an out-of-air emergency. These are suitable for relatively shallow dives without decompression.
