What is the maximum depth limit for recreational diving according to IANTD guidelines?

According to IANTD guidelines, the maximum depth limit for recreational diving is 40 meters (130 feet). This depth is considered the appropriate threshold for divers who are trained at the open water level, as it allows for a more manageable dive experience while still providing access to fairly deep dives.

Diving deeper than this recommended depth can increase the risks associated with pressure, nitrogen narcosis, and decompression sickness, as well as complicate the dive planning and safety procedures. Recreational divers are encouraged to stay within these limits to ensure that they have the necessary skills and experience to handle the physical and psychological challenges that can arise.

Staying within the depth limit ensures a balance between the exhilarating experience of exploring deeper waters and the safety measures that are essential for a successful dive.
