Hello Community,
a couple of years ago (too many to remember when exactly) I saw a scene in a movie where a small group of bikini-girls (like usual in movies, lol) were sort of training underwater at the bottom of a deep pool.
They seemed to be breath-holding, but used something like a drinkbottle, pretty similar looking to this (http://www.industrypromotions.com.a...g/promotional-budget-drink-bottle-750ml-5.jpg) without any external hose with mouthpiece, and seemed to regularly take a breath from it before giving to the next person, sharing it.
Since then, I always wondered, does such a device exist? What would it be called?
Hope for some answers from the experienced divers here around
