The ERDI Surface Supply Awareness course introduces public safety personnel to surface-supplied diving, where the diver air and communications are delivered from the surface through an umbilical. At the Awareness level you will learn how surface-supply systems extend a team capability, the roles of divers and topside crew, and how these operations are managed safely.

It is a strong fit for supervisors, tenders, and team members who need to understand surface-supply operations without diving them.

Why train with Sink or Swim Scuba

You’ll train with an instructor who spent years as a working public safety diver and still supports local dive teams today. As an authorized Interspiro distributor, we keep rental and demo equipment on hand and offer on-site demo dives, so your team can try gear before investing — and we can assist with your dive operations as you build capability. ERDI training runs across three levels — Awareness, Operations, and Technician — and we train public safety divers locally, nationally, and internationally, including teams as far away as Spain.
