Undercurrent, the private guide for serous divers, has been published since 1975. As a nonprofit publication, it takes no advertisements, its travel writers take no freebies, and it’s written just for consumer divers. While 11,000 subscribers receive Undercurrent through the mail, nearly 3000 subscribers receive it online and pay a lower rate.
Who doesn't love free scuba diving knowledge? We've added Undercurrent to our scuba diving links for safe keeping.
