Rebreather Day 1 (RD1) is a system and method for rebreather diving starting with the simplicity of oxygen-only fundamentals. The RD1 system is designed to be modular and user serviceable with most components being off the shelf with standard thread patterns. In addition, most components are designed to be user serviceable on the boat with limited tools.
Come see Jona from Explorer Technology to see how we can perform your RD1 Manufacturer Proficiency for all levels from L0 to L3.
We look forward to diving silent with you.
