Those older, large, robust first stages were from a time when divers usually dived locally. Dive travel mandated much lighter first stages, and the use of more plastic parts. But that doesn’t translate into better wear and tear, or even into better performance. What did was the ability to print out the plastic parts to much tighter specs that the metal parts, which Dacor was doing with its second stages toward the end of Dacor’s life.
