Calm instruction built around confidence, awareness and preparation.

Andrew's teaching style is practical, calm and experience-led. He is especially interested in helping divers build confidence, improve buoyancy, think clearly underwater and develop safer habits before problems become emergencies.

That safety thread runs through scuba, freediving, first aid, technical diving experience and marine rescue work.
