If you're into technical diving then you know that to extend your depth range you need to use trimix - a blend of helium, oxygen and nitrogen. The Tec Trimix 65 course introduces you to using trimix down to a maximum depth of 65 metres/210 feet. There are advantages to using three gases, but you need to know how to do it right.
