How often should a diver refresh their dive training?

A diver should refresh their training every couple of years to ensure they maintain the necessary skills and knowledge for safe diving practices. Over time, diving techniques, equipment, safety protocols, and environmental considerations can change, and regular training helps divers stay current with these changes.

Refreshing training reinforces previously learned skills and addresses any areas where the diver may need additional practice. This can include emergency procedures, buoyancy control, or use of new technology in diving equipment. While regular practice is essential, formal training every few years is sufficient for most divers to remain competent and confident in their abilities.

Other options suggest training intervals that may not align with the best practices for maintaining skills. Monthly refreshers may be impractical for many divers, while only refreshing when diving in new locations may lead to skill erosion. Annual training updates can be beneficial, but a two-year cycle is generally more widely accepted among divers as a good standard.
