Gettn somewhat frustrated with finding certain info and products involving boosters. I get their not cheap but who cares, I’d shell out the $ to be able to go to the range with several big bores, an scba tank and not have to bring a compressor cuz I’d have a booster. You can’t find one, you can’t buy one, it’s like the industry DOESNT want us to have one. This is what I got in reply from Altoros
