A software tool or online resource used to determine safe ascent profiles for divers, typically by applying established decompression algorithms like Bhlmann or VPM-B. These resources often incorporate factors such as dive depth, bottom time, gas mixtures used, and personal safety preferences to generate a schedule of decompression stops, minimizing the risk of decompression sickness. For instance, such a resource might suggest a series of five-minute stops at specific depths following a deep dive.
Accurate ascent planning is crucial for diver safety, and these planning aids play a vital role in mitigating the inherent risks of pressure changes during underwater activities. Historically, divers relied on dive tables with limited flexibility. Modern computational tools offer significantly enhanced precision, allowing for personalized dive plans based on individual factors and real-time conditions, improving safety and extending dive time possibilities. This enhanced safety contributed to the growth and accessibility of deeper and more technical diving practices.
