Welcome to the online edition of Undercurrent, the serious diver's source for unbiased, ad-free reviews of dive destinations, dive operations, and dive equipment since 1975.

Editor's Pick of the month

Tropical Ice

Written by Undercurrent's publisher Ben Davison (writing as KL Smith) and set in Belize, Tropical Ice is a story of shark-finning and reef-raping, murder and politics, on an industrial scale, with plenty of diving.

It all takes place at Cap'n Jack's Rum Caye Dive Resort, where Jack's trying to save his failing resort with shark-feeding dives, until a body turns up in the damnedest place.

Tropical Ice is available online from Amazon in paperback or Kindle, and in bookstores.
