Question about filling an air venturi 4500psi tank

[ASAirifle]

Hi Folks, I finally bit the pellet and purchased a Marauder because I was tired of getting headaches shooting my Nitro piston gun.  Wavered back and forth due to cost of the Air Venturi carbon fiber tank but finally bought that too when PA had their cyber monday sale.  It comes with the connections to fill the Marauder and I couldn't tell from any of the comments on the website if anything else was needed.

So I went to my friendly dive shop who can fill to 4500psi and it was the first time they'd seen that type of tank and did not have the ability to connect to it to fill it.  I was told I need a scuba yoke or a DIN connector BUT, I don't know if I use it in conjunction with the hoses that came with the tank or just directly off the tank.  For those of you with the air venturi 4500psi tank, which connector do you use when getting it filled at the dive shop?
Thanks for your help,
adam

these two would allow you to build up an adapter to fit the DIN male they have

or just give them the CGA-347 to install on their hose
