Not needed but it sure is nice

Well I went ahead and bought a new scuba tank regugator on e-bay for a lot less that air hog wants and I am glad I did it . I do a lot of target shooting so it probably is more benificial for me that some . No more over fills and valve lock on my big bores . Slower fills and tighter groups . Does dump a little more air at bleed off but the trade is worth it to me . Its kind of like you really dont need a scope but it sure is nice . Marvin
