I have already reached the reserve: at 50 kgF/cm2 it is considered "tank reserve", which indicates that you have to go up to the surface... that amount of air is enough to travel a few more minutes down there...

Ya alcance la reserva: a los 50 kgF/cm2 se considera "reserva del tanque", lo que indica que hay que subir para la superficie.. esa cantidad de aire da para recorrer unos minutos mas allí abajo...
