Mini Scuba Tank 0.5L Capacity Inflatable Diving Tank DOT Certified Portable Scuba Tank Support Underwater Breathing up to 16ft for Underwater Work/Underwater Recreation

Excellent product I liked it very much

Not for anything deeper then 3 feet

Super portable and lightweight, it’s perfect for quick dives or underwater tasks. It's really easy to use and DOT certified, which is reassuring. On the upside, it's compact and user-friendly, and works well for shallow dives up to 33 feet. But, it only gives you 6-10 minutes of air, so you need to keep an eye on your time. Also, you need special equipment to inflate it properly but filling it using an adapter and full sized tank takes minutes. It's great for pool time as it's so easily and quicly refillable.

Overall: Recommended! Great to get you started with scuba. Have used this a few times and it works surprisingly well. Refill is kind of tricky but you can get creative with electric pumps out there. Cheers

If you are shopping for one of these, be sure to read the fine print carefully. This little unit is well made and the parts appear to be very good quality. However, you have to be able to refill them with air (and frequently, since they don't last very long) and this unit did NOT come with a pump. They require a very high pressure pump. Basically you have three options. First, you can have it refilled at a dive shop, but according to most sources, you need to be a certified diver for them to fill your tank. And because it only lasts a very few minutes, that is not real practical. Second, you can buy a hand pump, which is not very expensive but it does require 20-30 mins of hard pumping to fill the tank. The last option (and most expensive) is an electric pump. This is the best, but most expensive, option. If this is something you plan to use very sparingly then the hand pump might be a good option. However, if you plan to use it a lot, you likely would want to invest in an electric pump.
