Yep, thanks for the response. I could have sworn I turned the valve all the way on, but who knows. I went to my LDS and bought a regular SPG and we hooked it up and then put the regs on the tank. She opened the valve but not all the way. When I breathed the regular guage went up and down with the breathing, but the Cobra did not respond as quick. So instead of going up and down it just kept going down. But once you quit breathing the pressure built back up and it went to normal. Which is exactly what happened diving. It kept going down and when I would surface "and quit breathing thru the reg" it would go back to normal. So it seems I either had a bout of stupidity and did not open the valve all the way or I had a bad valve on the tank. But either way my Cobra is working perfect!!!! Hooo Hoooooooooo
Thanks for the help
