Chikadiv small underwater oxygen Tank

Buy on Amazon

This little tank can be used as an emergency tank in a squeeze but it only gives you 5-10 minutes of air, normally back up tanks give you a little more air time. You can easily use this product to get to depths below 15 feet, which could potentially cause harm or death. The 8mm one-way inflation valve of the scuba diving tank can connect the refill adapter to fill up. This tank has very little volume, the pressure in the tank goes down quickly with each breath. The size of this tank can easily kill people if it's not handled correctly.

It doesn't come pre-filled so you'll need to get it filled up if you don't have a high-pressure pump.

• Great backup tank or for a quick/casual dive
• You can stay up for 5-10 minutes underwater with total freedom
• You can take it in your luggage for airplane journeys

SMACO hand pump

Buy on Amazon

The smaco hand pump's material feels more premium than its price would suggest. It works well, does exactly what it needs to, and it takes a very long time to charge it up. It is suitable for professional diving backup gas sources, fishermen, novice diving, amateur diving, firefighters, lifeguards, etc. It has a capacity of 0.5l, and can be used for 170 underwater breaths at full capacity. It is made of aerospace aluminium alloy that resists internal corrosion and stands up well to damage.

The diving bottle can be transported on the plane, because it does not contain gas. It is used for 5-10 minutes of diving time. The tank pumps up fairly easily, but takes a bit of time to do it.
