Hello,
I own the dive center the OP has shared the Facebook image of and offering the deal.
In full context, SSI is offering the Science of Diving online class and certification free of charge from April 12 - June 30, 2020 to their dive centers (presumably all of them but I'm not 100% sure of that). As a dive agency is concerned, I'm very pleased SSI is offering this and am hopeful all my divers will take advantage of their generous offer. Any certified scuba diver can register through their local dive center, though it's possible your local center may have administrative or instructor fees. As I own the dive center and will be the instructor on record (and secretary, assistant, and pretty much everythign else you need), I can skip on this fees easy enough. I did originally advertise this on my Facebook page and in an email blast to my clients in my database, but I'd be happy to honor it for any certified diver that contacts me by email letsgodiving@saltyendeavors.com
As for the nitrox certification getting discussed without the practical, I won't get into the merits of it but merely rely the SSI requirements. SSi breaks their Enriched Air Nitrox class down into 2 parts. Part one is the theory. This can be completed 100% online. We can perform any instructor > student direct discussion through any number of video chatting apps. Upon completion the diver is certified to 32% nitrox. Once the diver arrives to any SSI dive center and completes the practical application and dive, the certification is upgraded to 40%. If you complete this upgrade with us in Cozumel the upgrade will be free of charge. If you do it at any other SSI dive center you will be subject to whatever fees they decide. It should be noted there is no need to upgrade to 40% unless you feel the need to use EAN36 or EAN40.
I hope everyone is doing as best they can given the situations. If you'd like to take a few hours and study some SSI Science of Diving in your downtime, give me a shout!
You also personally posted it to the Chicago Scuba Meetup FB and that’s actually where I originally saw it.
