"Brian10956"I agree 100% with humdinger. One other option is to get in the higher end dive compressor is a gasoline engine driven pump. I like my Carette just didn't like the nickle dime experience from its distributor with shipping and surcharge for not paying cash it will finally cost over $1800....... I am glad I purchased mine from the manufacturer (i was a early bird) for $$1300 shipped I think, & purchased a Alpha filter from JB at a forum member discount=299 + $17 shipping, it would have been more if I had paid w/cc , I sent a $$ order instead & saved a few $$'s, but the Kicker is , I Explained that I was an (early bird) & when I received the Alpha ( just the filter w 1 90% male & 1 St male , (mine didn't come with a hose attached), it will not connect to the Carette (Q/C will not fit on the male Q/C ), called JB , they stated You did Not buy Carette from Us, so I still don't have a working compressor yet ( I will not use until I attach the filter), I am not sure what for positive the threads are to try modify to work , Believe me I am NOT SCAREd to say 4500Psi Scares the crap out off me. so Brian ,I am still a little less than $200 from where you are at , I have a fully optioned Carette, not sure what you have , I hope all is well, I know Humdinger REally likes his.. roger
