Fill out your profile a little more thoroughly. People will have a better gauge as how to respond, as said earlier by JBres1. Do you own your own gear? Where do you dive/live?
I have a couple of friends that have their own compressor set-ups in their garages, they do O2, also, for nitrox fills. However, they didn't do their set-ups until they respectively had 400+ dives. Also, one is a mechanic and the other an engineer. They both did a lot of research. One is trying to design a trimix stick to use in his garage. It works well for me, because I get free fills from them often!
Start with buying your own tanks, get them filled by professionals who have the training. Make sure they fit the type of diving you want to do. I have two tanks with which I regularly dive. They fit my type of diving (recreational) and my SAC rate (the rate of which I breath). I can usually get at least an hour of bottom time, depending on my depth. They are steel, so I don't wear as much weight on my belt. I do wish I had gotten low pressure tanks, instead of high pressure ones, because I don't get very good fills on most boats. Know that it is VERY easy to sell used tanks, so if your style of diving changes, you will not be "stuck" with them.
Ask questions and learn as much as you can. There really are no dumb questions, just a few jerks who answer too quickly with smart [alecky] comments.
I used to work at a SCUBA shop. I was trained to fill tanks and inspect them. It is not rocket science, but there are things you need to be aware of for safety.Get into a club that dives a lot, spend time on here reading and use the search tool. A lot of questions have been discussed pretty thoroughly here, so research and ask for clarification. Be clear with your question so everyone knows the answer for which you are looking.
Last, have fun with this most awesome of sports! Don't be afraid to try things, just always be safety conscious.
Happy Diving! :kiss2:
