The ERDI Surface Supply Operations course develops the hands-on skills to conduct surface-supplied dives as an active member of a public safety team. You will work with umbilical management, system setup and checks, topside and tender coordination, communications, and contingency procedures during real operations.

It is designed for certified public safety divers ready to operate surface-supply equipment on team call-outs.

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.
