"Same as it ever was"Airshootinest has done a bunch of testing and reviews. The real good ones are ultra expensive, and the cheap ones are.....cheap.
Well, I recently bought four expired SCBA tanks in very good condition for $50 each, so I've been filling them up one at a time from empty. I imagine that after I get them all filled that filling them from empty will be a very rare occurrence. I'm thinking that once they hit 3000 I'll be topping them off again.How often does one fill a tank from empty, though? Depending on your shooting, once it's down 500-1500 psi, it gets topped off.
Though it will take awhile for the CS4 to get street time similar to where the others are now, initially it seems to be a runs slower/cooler/MUCH quieter trade-off to the YH & Tuxing pumps. I like it due to no external bucket & water pump, quiet enough to run in the house, and doesn't try to vibrate itself across the floor.
Please clarify which GX model - there are significant differences between some of them.
