Good discussion here. So I am going to do the 40m cert this may for hovering around wrecks (non-penetration) and other sites interesting at 40m wherever they might be. Should I do a PADI TECREC or the SDI Course? I think ScubaZens post made me tilt towards PADI. But I'd like some quick opinions about the others - CMAS, BSAC, NAUI, IANTD, SSI, TDI for the record? I hope my question is not out of place on this thread?
Thanks
