Marvel:Frankly, don't have the answer to the air charge- I rent tanks at $7. Too late at night for me or I'd get you their # or website. You'll be in my back yard & I certainly have no objections to kids- in fact I kind of like the little critters ( 3 grandkids, you see). I'll get you some decent info on fills & perhaps we can get together while your down!!
Thanks! I have found that most people don't own their tanks. We brought 14 back from Okinawa with us. Paid $10-$35 for each. Otherwise we probably wouldn't own ours either. You said you rent yours for $7?? Is that for 1 day? And what if you decide to do another dive? Do they fill them for free? Thanks again! And we'd be more than happy to go dive with ya!
