We dive cold fresh water and warm salt water can we use this set up for both?

Hello, Yes you can. You can always dive a cold water reg in warm water but you cannot always dive a warm water reg in cold. So you will be fine. Hope this helps, Happy Diving, Instructor Bill OnlineScuba Established 1996 1 866 728 2293

Does it come with the first stage?

Hi, Thanks for your question. Yes, you will get the 1st and 2nd stage. Thanks Divemaster Chris 866-728-2293 Onlinescuba

Can this be used as a hookah 2nd stage surface supplied regulator 20-50 psi?

Thanks for your question! You will have to have a service technician calibrate the regulator down to match the lower pressures, otherwise it will not work. Once it is calibrated it can be used at that setting. Please let us know if we can further help in any way. HouseofScuba

Is there only one port?

Hi Nate, If you are referring the first stage, there is 4 low pressure ports and 2 high pressure ports. Happy Diving, Bill PADI Master Instructor OnlineScuba 1-866-728-2293 702-897-5111
