Could I use a 80cf aluminum scuba tank rated to 3500psi to fill a huben k1 or would it be better to use a compressor like the CS4? Pros and cons to each one would be greatly appreciated
Filling huben k1 tank or compressor

The K1 has a maximum fill of 5000psi. You'll get one fill at 3450psi from your tank, and then lesser fills there after.
I prefer filling my k1 and gk1 straight from a compressor. I originally used my AV 4500psi compressors but recently for a GX CS4, and its amazing.

Your tank may be rated to 3500, but good luck getting any SCUBA shop to fill it to that. The best I can do locally is about 3100. (It's a liability thing) They fill my steel tanks to 3450, because they are designed for that.
I can recommend the CS4, though you may wish to look at the new CS4-i with integrated PS. It's a cleaner config, without having to drag around a separate PS.

That’s what I figured. So the best way to fill the k1 with a bottle if I was going that route would be a scba high pressure bottle right?

My local shop will fill my aluminum tanks to 3600. The will fill hp steel tanks to 4500 but I only have lp steel tanks which they will fill to 3500

Well, my experience is that I bought said SCBA tank (the biggest one), but after just a couple of fills at $10, plus the drive, I decided I wanted a compressor.
But to put it into perspective, even at $10 per fill, and let's assume $3 in gas each trip, that's $13 for about 10 gun fills, so if you divide a $600 compressor by $13, that means I could have filled my gun at least 450 times for the same price. The convenience of being able to fill anytime/anywhere is something only YOU can put a price on for your particular situation.

Wow, that's good for you! Wish mine would do that. Especially since I have my tank marked FOR PCP ONLY, and have made it clear to them that I won't be using it for diving any longer.

I’ve been friends with most of the staff at that shop for 10+ years. It’s a luxury they don’t give most customers

Doesn't matter what YOU write on a tank. Dive shops have strict protocol they have to follow regardless of what tank owners intentions are. They just follow the rules of their licensing. SCBA tank will serve you better, getting closer to the max capacity IF you verify with a shop that they can & WILL fill to 4500psi.

Pretty sure I said all of that above. I have been diving since 1990, I know the rules. Obviously, as in the case of the OP, there still exist dive shops that willingly break the rules.

If you’re in the palm beach/broward area I can suggest some shops that will give you higher fills

Sure thing! I'm in Davie, so Palm beach is a tad far of a drive for air. But if you know any closer to me, feel free to share.

Still not that close to you but Dixie divers in Deerfield used to always max my fills out. I think they still have a location in Lauderdale but I’ve never gone to that one.
