Training is essential and can be arranged through the Scottish Sub Aqua club (SSAC), which offers diver training suitable for local conditions. SSAC has a number of branches across the country. Courses range from beginner to instructor level. Some SSAC branches also accept visiting divers with qualifications from other organisations. A range of dive companies exist in Scotland, including those offering accommodation on board dive boats which can see you out at sea for up to 7 days.
