This is scuba gear. You get a small scuba tank and a pump to fill it up. Had another small tank but no pump. So hopefully this fills both of them. Good find. Read more

This is not what you want! It’s impossible to fill this up with this pump! Me and my husband really struggled and we were taking turns! 25 min nonstop pumping for about 5 min use ! Read more

I consider this a really unique item for anyone who enjoys the open water or has a backyard pool. In my case I have only had the opportunity to experiment with this in my pool. I've seen similar items in the movies and wondered if they really work. Well I have to tell you that I was impressed! Not only did it work it far exceeded my expectations. Of course you might already be familiar with snorkeling, but the difference here is you can breath through your nose & mouth (get the mouth piece sold separately) normally through the full face mask. It makes a nice seal around your face with little to no water leakage. You'll have to order your own mouth piece but they're available on Amazon. The included pump allows for refilling the air tank for underwater breathing and comes with the pump included to refill the air tank. All of the components are made from high grade material. Assembly required for the pump and face mask with easy to follow manuals. Tip... how long you can stay underwater breathing will depend on how deep you dive and your breathing rate. Read more
