Equivalent Air Depth Tables

EAD tables show the equivalent depths for different Nitrox blends at various actual depths. This helps divers plan their dives safely when using enriched air by converting their actual depth to an "air-equivalent" depth for decompression planning.
What is Equivalent Air Depth?
The Equivalent Air Depth allows you to use standard air decompression tables while diving with Nitrox. By knowing your EAD, you can accurately calculate no-decompression limits and reduce your risk of decompression sickness from excessive nitrogen absorption.
