What does Diver´s 7 mean?
Since ancient times the human race has being creating new words to describe the environments, describe connections and finally explain the world we live based on their history, culture, beliefs and their interactions.
From Mesopotamia about 2300BC, Persians, Indians, passing through the Romans, Arabs, medieval Europe, age of navigations until modern days all over the world, the term “Seven Seas” has being used to describe a stream, body of water, lagoon, rivers or even the seas that connects with a portion of land or creates more connections with more water bodies.
As Diver´s 7 this is exactly what we want. We are creating a space that people like us can connect, share, experience and enjoy the sea. People from everywhere, divers from all the Seven Seas and with the ocean that connects us to everyone and everywhere we enjoy and share great time together.
