What is the reason people want super high flow 1st stages when using a FFM??? Why couldn't you use a normal reg like a Scubapro or the Atomic series???
Is there a minium CFM (cubic feet per minute) from the 1st stage when using a FFM?
The reason for this question is that many FFM offer a 1st stage.
Thanks
