Visibility is the most important aspect of any dive. The M1 mask raises the bar for optical quality and distortion free vision. This lens is an extra clear glass which is valued for its attractive appearance and optical qualities. The low iron content produces a higher light transmittance and a reduced green tint inherent in other glasses. This makes the lens distortion free and helps improve color and visibility in low light conditions underwater.

From one of the world’s most renowned cave divers, a firsthand account of exploring the earth’s final frontier: the hidden depths of our oceans and the sunken caves inside our planet

Deco for Divers provides a comprehensive overview of the principles underlying decompression theory. Mark Powell has written a book that for the first time allows the average diver to fully understand the principles behind this fascinating aspect of diving. This book bridges the gap between introductory books and source scientific information.

This book is for all scuba divers and those interested in diving, regardless of diving certification level or academic background. The purpose is to present the interesting concepts behind the physiology, so all can understand and enjoy.

Most incidents and accidents are down to "human error". Unfortunately, human error is normal and common, and we can't get rid of it. However, we can reduce the likelihood of one of those - "oh shit moments" - if we have an understanding of human factors and develop our non-technical skills.

This book is a must for all divers who want to manage their risks more effectively and have fun in the process.

In this masterful account in the spirit of Bill Bryson and Ian Frazier, a longtime deep-sea diver masterfully weaves together the science and history of Earth's last remaining frontier: the sea.
