What Does BT Stand For?
BT stands for Bottom Time
Bottom Time (BT) refers to the total duration a diver spends at a specified depth during a single dive, excluding the time spent during ascent or on the surface. It is a critical factor in dive planning and safety, as it influences the risk of decompression sickness and requires careful monitoring to ensure adherence to safe diving limits and protocols.
