DIVE BUBBLES
The idea was simple and valid: to perfect the system in vogue in the old days of regulating one's ascent rate on the speed of the exhaled bubbles.
However, as the bubbles rise, they increase in diameter and therefore in speed, forcing you to change the reference ones often in the difficult attempt to maintain a constant pace. The "Dive Bubbles" promised just that, being calibrated to go up at a constant 20 m/min. Furthermore, there were two colors, specific for the density of fresh water and for that of salt water
