The ERDI Full Face Mask Technician course certifies you to dive and work in a full-face mask as a fully proficient member of a public safety dive team. You will master donning and doffing, valve and regulator management, integrated communications, and emergency procedures with the mask, operating confidently in the conditions PSD teams face.

This is the highest full-face-mask proficiency level and is built for working public safety divers.

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.
