The ERDI Dry Suit Diver Technician course certifies you to operate confidently in a dry suit as a working member of a public safety dive team. You will master buoyancy and trim, valve management, emergency procedures, and dry-suit-specific skills for cold-water, extended, and contaminated-water operations.

This is the advanced dry-suit proficiency level, built for public safety divers who rely on dry suits in the field.

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.
