I have been eyeing a new reg for some time now, and my awesome wife surprised me with an Apeks DST/ATX50 as a graduation (grad school)/father's day gift. She even had it converted to DIN for me. I am planning on using the new Titan octo I just bought for my old regs until I can buy another Apeks second stage. Is there anything I should know about this setup that anyone is aware of?
