Carbon Monoxide is odorless and tasteless which is one of the things that makes it so dangerous. While it is busy tying up all your hemoglobin and depriving you of oxygen, you won't even know it.
A dive shop will have it air tested periodically, normally every 6 months to ensure that it meets the required standards.
Air here runs $4.00 a fill and Nitrox is $10.00 a fill at the LDS. However we also have an air club and the membership costs $30 per year for a single and $50 per year for a family. The 17 cfm automatic compressor feeds an 8 bottle air bank and lives at the LDS. There are whips for 2250 psi and 3000 psi tanks with automatic shut offs (at 2500 and 3300 psi) so the dimmer members of the club won't blow themselves up doing their own fills. The whips are in locked cabinet outside the LDS so that members can get airfills anytime day or night. I figure my airfills cost less than .40 each during the average year. The LDS gives air club members a break on Nitrox fills (5.00 per fill) as he only needs to supply the O2.
For keeping and maintaining the compressor, the LDS owner gets unlimited use of it and makes the $4.00 per fill off the non air club members. The LDS also sells the meberships, keeps the books and trains new members how to fill tanks. The LDS also monitors the air club members and their tanks to ensure the tanks are properly hydroed and inspected (violate this policy on a regular basis and you forfeit your membership). The LDS is also has a hydrotest facility on site and makes the money off the hydros ($12.50 per tank) and the VIP ($5.00 per tank). The LDS also benefits as air is very cheap and many new students get certified who would not otherwise, many more divers dive more than they would otherwise, and all of these very active divers in turn buy more equipment and get more advanced training than they would otherwise.
Business is booming for the LDS and it is a sweet deal for everyone. He saves overhead on a buying and maintainig a compressor, makes money off the air sold to non members, gets additional profits from equipment sales and training and does nearly 100% of the hydro/vip business in the area. We get free space and free maintenance for the compressor and airbank, cheap hydros and VIP's and cheap air and nitrox fills, and access to air fills 24 hours per day. .
