The presentation introduces a Buddy-Watcher device that aims to address safety issues in scuba diving by helping divers monitor their buddy. It works by using technology solutions from the radio sector to overcome challenges with underwater communication. The device provides functions like variable distance alerts, vibration alerts, an SOS button, navigation and locating capabilities to help divers stay connected and assist each other during dives. Its goal is to enhance safety by making it easier for divers to watch their buddy as required by diving organizations.

7. Communication & Difficulties
Under water communication is difficult due to factors like :
•
multi-path propagation, (reflection, absorption)
•
small available bandwidth
•
strong signal attenuation
•
acoustic waves
Use of “Technical Support” by ESA :
• Equal problems with electromagnetic/ pressure waves
• Using solutions of radio sector
