Don’t know how much you’ve read or familiar with compressor ownership but it has it’s ups and downs, especially depending on the amount you budget for. The water cooled Yong Heng’s seem to be the most dependable of the smaller compressors. But they require cooling water which in the field is a little inconvenient. There are air cooled ones that seem to be half way decent. With any of the smaller, under $400, compressors you should be prepared or willing to do service work on it. You don’t have to be an aviation mechanic to do it but maybe have some aptitude.
If you budget a Bauer, Alkin or maybe a Coltri you’re going to get a lot more fills between service intervals but they aren’t as portable.
Also, the smaller compressors are meant more for 480, 500 or 700cc gun mounted bottles but some people do fill the large carbon fibers with good results, it just takes a while.
Now, being you have a dive shop nearby get easily get fills. Being you had a scuba tank you got fills on you are probably aware of yearly tank inspections and 5 year hydro test cycles. A carbon fiber will have the same requirements, hydro might be a bit more expensive, possibly the fill too.
Those are a couple factors to consider. Depending on how often you shoot you might be able to get by with one, maybe two 74 or 98cf carbon fiber tanks. But you’ll need to crunch numbers to make a decision.
I have an Alkin and two 74cf carbon fibers and those two carbon fibers will keep me shooting for a long time.
