This wiki has been updated 11 times since it was first published in August of 2019. Sometimes called pony bottles, divers often carry a mini scuba tank with them to act as a redundant air source in case of an emergency underwater. While these can be used relatively safely at shallow depths of under three meters to clean a boat or swimming pool or even do some light exploring, scuba diving without proper training can be extremely dangerous, and we strongly advise against it. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki. Skip to the best mini scuba tank on Amazon.

Editor's Notes

September 09, 2019:

Sometimes called pony bottles, divers often carry a mini scuba tank with them as a safety precaution, to act as a redundant air source underwater in case of an emergency. While many users also report having great success using these devices in shallow water, exploring while snorkeling or cleaning a boat or swimming pool, the dangers involved with swimming in deep water without training can’t be stressed enough.

Unsafe diving practices can result in barotrauma or even death by suffocation. Make sure you receive proper training and certification from an accredited instructor before attempting any sort of serious scuba diving. While offerings in this category are commonly rated for depths of 50 meters, a safe depth to dive at without training is something closer to three meters.

Options in this category tend to be quite similar in their design and functionality, but you'll want to keep an eye out for their tank volume/capacity – as it speaks directly to the weight of the unit and the length of time it can keep you underwater for, and whether or not they include a regulator – as it’ll amount to an additional cost to you if not. Also, unless you've already got a wetsuit and harness ready to go, you might want to pay special attention to options like the Spare Air Extreme Watersports Rescue Kit, which comes with a black neoprene vest that can accommodate your new gear.

His past career landed him a depth of knowledge in tools and hardware, while his current career schooled him in audio, video and camera equipment. During his leisure time, he’s learned lots about outdoor gear, and years of tiresome backyard maintenance have taught him all about pools and hot tubs. His recreational pursuits include rest, relaxation and revolutionary action, and his roommate’s a hairless cat.
