I was wondering if these regs have a bad batch of High pressure seats. I purchased 3 new ones about 4 months ago, and have had all of them split the high pressure seats in half. My dive partner purchased 3 at the same time and 2 of his had to be replaced. This is of great concern to me since these regs are used in Cave and other tech diving. In fact I am thinking about getting rid of these regs because of this. I would like to know if Oceanic is planning a recall. One reg is an accident, not 5.
