Gradient factors

Gradient factors (GF) are an important component of many modern dive computers and decompression models. But what do GF Low and GF High actually mean, how are they related, and how can we visualize their effects graphically? In this video, we’ll take a look at what gradient factors are and what role GF Low and GF High play. Using simple graphical representations, I’ll show how their effects on a dive can be illustrated and what lies behind these two values. The focus here is deliberately on a basic understanding of the concept. The video is intended to help you better understand how gradient factors work and to grasp the significance of GF Low and GF High. If you’re not yet familiar with the basics of decompression theory, I recommend my video on decompression theory (   • Decompression theory  . In it, I explain the key concepts related to nitrogen absorption, desaturation, tissue groups, and decompression models, which form the foundation for understanding gradient factors.
