  • SEBiger300 diving tank is crafted from 6061 aviation aluminum, and its three-layer design enables it to well withstand the corrosion of seawater. B300 has a 0.5liter capacity, which can support 5-10 minutes of underwater diving. Nevertheless, the actual diving time might be different due to factors such as diving depth, temperature and personal diving capabilities.
  • A 5K explosion - proof valve is designed at the valve head. When the pressure inside the cylinder reaches or exceeds the fixed value of 5000 psi, the gas will break through the internal explosion - proof copper sheet and leak out, so as to reduce the pressure inside the cylinder. Once the explosion-proof copper sheet is damaged, it needs to be replaced before diving. SEBiger scuba cylinder adopts a bite mouth made of food - grade silicone to ensure a healthier and safer using experience.
  • SEBiger mini diving kit is a diving system. You can disassemble the body and valve head of the diving cylinder, so that you can take it on the plane and take it around the world to fully enjoy the fun of diving. This kit can not only be used as a backup air source, but also can provide assistance for various shallow - water activities such as leisure diving, treasure hunting, ship cleaning, and rapid entry rescue diving.
  • If you have a diving qualification certificate, you can directly inflate it at the diving shop. It takes about 4-8 seconds to inflate using the SEBiger scuba adapter; it can be fully inflated in approximately 11 minutes by using the SEBiger air compressor; inflating with the SEBiger hand pump takes about 25-30 minutes, which is relatively difficult, so it is recommended as a backup device. The working pressure is 3000PSI/200bar/20Mpa.
  • You will receive a diving tank, an anti-lost rope, some additional accessories and a user manual. The contents of the user manual also provide comprehensive guidance for your use. Our scuba tanks provide technical support and after-sales service. If you have any questions about diving equipment products, please feel free to contact us and we will answer you as soon as possible.

I love this tank! I use it on my boat all the time. I have a scuba tank with a paintball whip. It takes literally 1 second to fill this tank. I do not use a hand pump at all. I love using this to go down and help set my anchor. It will last about 10 min of use. I am a bigger guy so I breathe a little more. This is a great tool for boaters. It's not meant for going deep. I highly recommend taking a scuba class to understand pressurized gases and diving. I am a certified diver and understand the risks and skills needed to safely use this tank. It is very light. I have an underwater scooter and it's nice to dive down a bit when snorkeling around. This is my second one and I love these!

This is a heavy solid well built tank (which is a plus). The mouth piece is very flexible which makes it more comfortable while in mouth. It came with replacement o rings which is also nice to have a quick replacement. Gage is small but easy to read! It has an inflation plug that I believe you need a special attachment if you were to use a air compressor?I have not used it yet because waiting for warmer weather so my kids can use it in the pool. It says tank should last 4 to 5 minutes on a full tank. Not very long but enough for kids to play around with. It also has safety features as well. Tank is about the size of a long aluminum water bottle. Easy to hold with a cord if it is dropped.

Great pony bottle! You can use it as an emergency spare air or for recreational snorkling (again, just as a back-up in shallow water). Remember that you can get bent if you breathe off of compressed air while free-diving at depth, so please be careful. Also, no reputable scuba shop will fill it if you don’t have a certification card. Also keep in mind that there is no pressure gauge, so you won’t know when it’s going to run out. Top it off after every dive to be safe!! But for properly trained divers, I highly recommend this little pony bottle.

The design of the set is very thoughtful, especially for short diving trips! The two 0.5L cylinders are lightweight and easy to carry with you in your backpack.
