I agree but as you mentioned, the cost per fill for the diver includes his cost of getting to and from the shop so he isn't getting a fill for $10.
That my point. Let's say the total cost of getting a fill includes travel to / from the shop and the divers time.
If we assume a 40 mile round trip, and figure fuel only that's $6-7. Lets say an hour of the divers time, @ $20 / hour.
Now the diver has spent $5 for a fill, and $27 dollars in time and travel, or $32 for that fill.
If the price charged by the dive shop doubles to $10, the total is now $37. Doubling the price of the fill only increased the "cost" by about 15%. It seems unlikely to me that a 15% increase in cost will motive many to buy a compressor.
Of course my example assumes one trip to fill one tank, and filling more tanks per trip will change the percentages, but of course then you need to buy the extra tanks.......
