When you amortize the investment out over the hundreds of thousands of fills it will give you it ends up costing you pennies per fill (virtually free) and when you deduct the revenue generated from air sales from that initial investment it becomes even cheaper. Air fills are dirt cheap, im sure they spend more in the labor for the tank monkey to hook up the fill whips, but at margins they earn on the tanks themselves its hardly worth it.
"High-pressure" 3442psi rated cylinders do not require DIN regulators. They are usually sold with convertible valves so that you can use either DIN or yoke fittings. A yoke regulator will function just fine.
One of those myths, kinda like you can't put air in a nitrox cylinder, or that once your switch to synthetic oil in your car you can't use organic oil afterwards. Nonsense.
You learn something new on scubaboard everyday.
a LDS is offering free air for life, when you buy a steel tank from them. the tanks are 80's for $275 or 100's for $355. the way i got that figured, at $7 a fill (AL80 last years price) that is 37 and 50 fills repectively, to pay for themselves. too good to be true?
what else should i look for in the deal? they are the closest to my house with one of their stores, and on the way to nearby dive sites with the other 2 stores. i don't see them going out of business, but......
any input is valued. thanks
also, i don't know all there is to know about tanks. if some one could direct me to a thread that explains hp lp pros cons etc.
For HP steel tanks you will need to convert your regulator(s) to DIN.
I'd verify or check anything learned on ScubaBoard with other reliable sources. Everything I've seen posted is not gospel, or in some cases, even true. You are responsible for yourself.
Love your enthusiam, but I am sure you meant United States Navy Master Chief (Marine Corps does not have that rank).
Thanks for the correction. I know for a fact, he was a Marine lifer, so what would the equivalent be? I've heard the term Chief bandied around, so I assumed he was a Master Chief.
Master Chief Petty Officer in the Navy is an E-9
Marine Corp E-9 Equivalent rank/grade is Master Gunnery Sergeant or Sergeant Major (both E-9's with a slightly different job)

The earlier generation 3500 PSI cylinders do require a DIN connection. The newer models solved that by shaving a few atmospheres from the rating.
