I’m selling my Booster pump. This thing works great it will let you keep topping off your guns even when your tank has dropped below a useful level.I have toyed with the idea of using Nitrogen which most of the time comes in large tanks with a pressure of up to 6500 psi this could really come in hand as Nitrogen is not cheap. If this is you or a scuba tank guy this will allow you to get many more fills. This also comes with a line gauge for those guns with no gauge . I’m selling it and a in-line gauge for $600 shipped to lower 48 states. Feel free to text 812-449-1963 Mike.
