Scuba diving with the use of propulsion means is clearly increasing due to the reduction in prices and the advantages in terms of distances that can be traveled and reduction of physical effort while diving. Scientific studies in this specific area are few and we know little about the real physiological effects that the use of underwater thrusters produces, on the effects on diving stress.

The purpose of this protocol is to investigate the physiological effects of using scooters while diving, in particular the effects on the formation of circulating bubbles in relation to diving profiles by increasing data collection through citizen science.
