all I need for scuba shops to be able to fill the dive tank, and also for me to fill my marker? and does the 300BAR fill rig screw into the existing jobby on the tank? or is it instead of this? (excuse the techinical terms! )
cool, looks good. Im certainly interested, I will let you know next week as my mate has to get back to me about the tank. I will pm you. Also can I pay you by paypal or credit card?
