Yes - All that is required is to watch the shadows created by the oven. When the shadows are even on all sides the cooker is directly focused. The built in leveling leg on the back of the oven allows for easy tracking.

The Global Sun Oven is equipped with a built in Levelator device, an inner shelf that pivots to always keep food level and avoid spills while the oven is being refocused.

The need to refocus depends a great deal on what you are cooking, the time of day, and the temperature you wish to maintain. A good rule of thumb is to plan to readjust every 30 minutes to maintain maximum heat.

At noon the sun is high in the sky and moves quickly past the maximum focus point, creating the need to refocus more often. Later in the day you will not need to refocus as often. Many meals can be cooked without refocusing.
