VUSE Altos are electronic vaping devices, and they are primarily composed of materials like plastic and lithium-ion batteries. While metal detectors are designed to detect metals, they may pick up only certain components of the VUSE Altos.

1. Metal Components: The device contains metallic parts, including the heating element and connectors, which can be detected by metal detectors.

2. Plastic and Battery: The outer casing of the VUSE Altos is typically made of plastic, which is usually not detectable by standard metal detectors. However, the lithium-ion battery might be detectable due to its metallic components.

3. Detection Variability: The sensitivity of metal detectors can vary significantly. Some detectors may pick up small metal components of the device, while others may not detect them at all, especially if they are minimal or covered by plastic.

In conclusion, while VUSE Altos may have some metallic components that can be detected, the overall device might not be reliably detected by metal detectors due to its predominantly plastic construction.
