Tec Basics bridges recreational and technical diving. You'll get used to twins or sidemount, a long hose for gas sharing and, if you're 18 or over, a stage cylinder, and find out whether Tec is for you.
If it is, it can count towards your Tec 40, as long as you use the same kit configuration. If it isn't, you leave with a card and sharper trim and buoyancy.
Tec Basics is optional. We'll decide together whether it's right for you once we've talked through your diving.
