A "dive buddy" is a partner who accompanies a scuba diver during underwater exploration. This practice enhances safety, as divers can assist each other in emergencies and share the experience. Having a dive buddy is essential for monitoring each other's air supply and ensuring proper communication underwater. Dive buddies typically follow specific guidelines, such as staying within a certain distance of each other and conducting regular checks. This partnership is crucial for both recreational diving and training, as it fosters teamwork and helps divers build confidence in their skills while exploring the underwater world.
