Funny hand signals

The app displays a photo of the marine animal with every hand sign. You and your dive-buddy will always be speaking about the same thing!

We acknowledge that not every existing hand signal has been included in this app. Through the active imagination of the diving community, new signals are constantly coming up. We would like to offer you this first edition as a glimpse into the diversity of underwater communication.

No internet access required, important for use during your vacation!

However, should you find any hand signals have been left out or not included, feel free to enter your suggestions in our ok2dive-Blog www.ok2dive.de/blog at "Mitmachen" or "Join in" or mail your suggestion to [email protected].

Find "your" dive signal included in upcoming editions. Help to develop and grow the divers language!

For those not owning an iPhone or iPod touch the english printed version of the Dive Signal booklet is coming soon (right now available in german).
