Subsurface vs Scuba Dive Signals

Subsurface-mobile is an iOS dive log application based on Subsurface, the best free open source dive log application available on Windows, Mac and Linux. Subsurface-mobile allows you to access your dive log on your tablet or phone, edit the data and even download new dive information from many Bluetooth LE enabled dive computers. Using a free Subsurface Cloud Storage account you can synchronize your dive data with the Subsurface desktop application (while significantly increasing the usefulness, the cloud account is not required to use Subsurface-mobile). To get support from the developers, please use the in-app menu entry "Ask for support" Please check out the Subsurface-mobile user manual: https://subsurface-divelog.org/documentation/subsurface-mobile-v3-user-manual (also available from within the app) Subsurface-mobile is free and open source. No ads, no commercial anything. And it comes with free cloud storage (if you decide to use that - it's optional). Your data aren't used for anything, nothing gets monetized.

Access a handy list of dive signals to safely communicate underwater while scuba diving. This contains a list of hand signals generally recognized by the Recreational Scuba Training Council and its member agencies (PADI, NAUI, SSI, and more). Once you've studied up, you can quiz yourself on what you've learned-- the app will show a series of five dive signal descriptions and give you a choice of four different pictures-- only one will match, so choose wisely! As always, safety is paramount when scuba diving, so be sure you are your diving partners are clear on their meanings before diving.
