The low gradient factor (GF Low) represents the beginning of decompression stops during a dive. In decompression diving, gradient factors are used to determine the ascent profile a diver should follow to minimize the risk of decompression sickness. GF Low is specifically related to the lower limits of the pressure gradient at which the diver should start making staged decompression stops.

By establishing this factor, divers can ensure that they ascend at a safe rate, allowing their bodies enough time to off-gas nitrogen and avoid the accumulation of bubbles that could lead to decompression sickness. Therefore, GF Low effectively sets the threshold at which the diver transitions from free ascent to structured decompression, making it a critical component of safe diving practices.
