That would be in line with similar regs and why I dropped mine to 135. If I am diving water in the low 30's I will probably drop it lower.I thought specs were 135 to 145.
You might want to PM Chris (cerich) and ask him what the factory setting is supposed to be. If it is supposed to be high (I doubt that, but just saying . . .), then an understanding of why would be helpful. But, if it is supposed to be in the 'usual and customary' range, say 130-145, and yours came from the factory at 175, and grf88's came at 155, Chris may want to know about that. Yes, as tbone points out there may be some settling over time with seating, but new regs should be sufficiently cycled before shipping to customers.I'm using a new Deep6 regulator and was surprised to see the IP at 175 from the factory. . . . Does anybody else have an experience with a hog or Deepsix regulator starting with an IP this high?
