![]() ![]() This means the diver should not spend more than 60 minutes at that particular depth. Exampleįor instance, if a diver starts with a pressure group difference of 2 and has a pressure group time factor of 30 minutes for a specific depth, the NDL will be 60 minutes. Pressure Group Time Factor (PGTF): This value signifies the allowed time at a specific depth for a given pressure group.Pressure Group Difference (PGD): The difference between the starting and ending pressure group after a dive, considering the surface interval.The central formula powering the Dive Time Calculator is: NDL = (Pressure Group Difference) × (Pressure Group Time Factor) Where: Properly Formatted Formula with Variables Description The precise nature of these calculations is essential for maintaining safety standards in diving. ![]() Once these values are entered, the calculator gives the maximum safe dive time for the diver. The most common formula used, the No Decompression Limit (NDL) formula, takes into account the pressure group difference and the pressure group time factor. Detailed Explanation of the Calculator's Workingĭivers use the calculator by inputting certain variables related to their dive. It's essential in ensuring that divers avoid potential decompression sickness. DefinitionĪ Dive Time Calculator is a tool primarily used by scuba divers to determine the length of time they can safely stay underwater at a given depth without the need for decompression stops during ascent. This device calculates the maximum allowable time one can spend at a particular depth, ensuring a safe and pleasant diving experience. One essential tool that helps them remain safe below the surface is the Dive Time Calculator. But, as captivating as it is, divers need to ensure safety. The underwater world is a place of wonder and mystery. ![]()
