The Razor Sidemount System
The Razor Side Mount System is a complete integrated system designed specifically for sidemount diving. It can be used for both cold water diving with Drysuits and Steel tanks and warm water diving with Wetsuits and Aluminium tanks.
There is no substitute for experience and finding out what really works in practice rather than just in theory.
The development and testing process of the Razor Side Mount System has taken several years and hundreds of Side Mount dives under real world conditions with most dives being conducted in the cave environment by some of the world’s most experienced side mount divers and cave explorers.
