About the Underwater Dictionary

It's a new take on organizing and documenting the world's underwater hand signals. We don't claim to list the correct signals - we aim to list all of the variations from all around the world!

We are not hand signal experts - we are enthusiasts who created a place for people to share hand signals around the world.

Different people use different hand signals, and those signals vary around the world. We want to document them all here. Ambitious, right!? Well, we are hoping you will want to pitch in.
