I found an old OW manual (probably on eBay) that I bought and read prior to my first Discover SCUBA dive, and I found the information in the first few chapters both interesting enough to motivate me to take the next step, and also very helpful preparation. I now have a friend in a similar situation, but I've tossed that old OW manual. With all the resources of the inter-webs, are there any suggestions for reading prior to the Discovery dive?
