In T pattern navigation, how frequently should divers check their position?

In T pattern navigation, divers must periodically check their position during the dive to ensure they are on track and navigating correctly according to their planned route. This approach allows divers to adjust their path as needed based on visual references and environmental cues they encounter underwater.

By checking their position periodically, divers can confirm they've maintained the intended course and avoid potential disorientation. This practice not only enhances safety but also improves the efficiency of the dive, ensuring they reach desired sites or landmarks as planned.

While checking before a dive, after every dive, or only at the end of the dive may seem relevant, these methods do not provide the continuous reassurance necessary for effective navigation during the dive itself. Regular position checks throughout the dive ensure divers remain oriented and can respond promptly to any unexpected changes in their environment or buoyancy.
