1. Elevation Sensing: The wands can accurately sense the elevation of the concrete surface being paved. This is crucial for maintaining a consistent thickness and smoothness across the entire paved area.

2. Steering Assistance: By sensing the elevation, the wands can provide steering assistance to the paver operator. This helps ensure that the paver stays on the correct path and maintains the desired grade.

3. Accuracy: The wands offer high accuracy in elevation sensing, which is essential for achieving precise grades and slopes in the finished concrete surface.

4. Versatility: The availability of different wand sizes (6″, 8″, 12″, and 16″) allows for versatility in application, catering to different paving widths and requirements.

5. Efficiency: Using these wands can improve paving efficiency by reducing the need for manual grade checking and adjustments, leading to faster and more consistent paving results.

Overall, these wands play a crucial role in modern concrete paving operations, helping to improve accuracy, efficiency, and the quality of the finished pavement.
