I know when we did our Nitrox check out dives with Discovery in Beaufort the instructor was curious to know what pressure was left in our tanks after a 40min dive to 70 fsw. When I told him just over 2000psi in my lp121 he was amazed til I told him I started with 3000. Thats when he pointed to the Max pressure on the tank 2450psi & stated that was the highest they would fill them.
Ive had them to 3300 before & since.Our LDS said they pressure check them at the factory much higher than that. I personally like to have as much gas as possible.
