What is a primary reason divers utilize locators during night dives?

Divers utilize locators during night dives primarily to help navigate back to the entry point. Night diving presents unique challenges, including decreased visibility and the disorienting effects of darkness. Locators, such as dive lights or other marker devices, assist divers in maintaining their bearings and finding their way back after exploring underwater.

Using a locator ensures divers can track their route and return safely to where they began the dive. This is crucial because in low visibility conditions, familiar landmarks may be harder to recognize, making navigation challenging. While features like attracting fish or signaling for assistance may play roles in a dive, the primary and most vital function of locators in this context is for navigation and ensuring divers can safely return to the entry point.
