PADI DSMB BUOY
Signal your position
The DSMB Diver course is practical training for divers who want to learn how to deploy and use a surface marker buoy correctly and confidently during a dive.
A DSMB allows you to signal your position at the surface before you ascend. This is particularly important in areas with boat traffic, in stronger currents, or when surfacing far from shore or the dive boat. The buoy line can also serve as a reference point during a safety stop.

Data Under Control
At Demon Ray, we have developed At Demon Ray, we have developed PhysioDive Lab – an innovative project that makes it possible to observe and analyse the body’s responses during a real dive..
During selected dives, we can record physiological and environmental parameters to observe how the body responds to depth, temperature, physical exertion, stress, and changing underwater conditions..
It is an additional training tool that allows you to look at technical diving not only from the perspective of the procedures performed but also to understand what is happening in your body at the same time..
- Monitoring heart rate and gas consumption
- Biometric data analysis
- Thermal monitoring and testing of undersuits
- Recording environmental conditions
- Analysis of stress and physiological strain
