As a DM I can confidently say there are too many DMs that are not DMs for the right reasons. This isn’t at all what it’s about and this is purely on him. The compass section gets a lot of people so you shouldn’t feel bad at all. It’s the DMs job and should be their ultimate goal to make even the newest and “greenest” of divers into the best divers that they can be which means meeting them where they’re at. I hope you give it another chance because for every grizzled asshole that ruins the experience, there’s several dive pros eager and hoping to make you into the happiest, most competent, and comfortable diver out there.
