There are a number of slick diving magazines available, but each month I look forward to a slim newsletter called Undercurrent.
It’s like a Consumer Reports of the diving industry. With no paid ads, they’re not beholden to anyone. Like restaurant reviewers, their critics visit diving resorts anonymously—getting the same treatment that you will—and present a full report, warts and all. Unbiased equipment evaluations, practical consumer advice, and sound safety tips round out each issue.
