What is a key benefit of the shadow-tip method in navigation?

The key benefit of the shadow-tip method in navigation is that it provides an immediate visual direction. This technique utilizes the sun's position to cast a shadow from a stick or an object planted in the ground. By observing the shadow, navigators can quickly determine cardinal directions, which is particularly useful when other navigational aids are unavailable. This method is effective because it offers a straightforward and direct way to orient oneself in the environment without needing additional tools or technology.

While the other options mention various advantages of navigation techniques, they do not directly pertain to the shadow-tip method's core functionality. For instance, nighttime navigation requires different techniques since the sun is not visible, and while it may reduce reliance on electronic devices, it does not inherently eliminate the need for them in all situations. Simplifying map reading is not the primary focus of the shadow-tip method, as this technique primarily aids in establishing position rather than interpreting complex maps.
