You need to include a Garrett carrot pin-pointer with every M-6 sold. This whay the process line worker can easily inspect flagged product units and find the metal contamination quickly and precisely for best fault failure analysis! It’s great to keep the metal contaminants from going out into the public however if they don’t identify exactly what the metal contamination is how can they trace the root source for failure trend analysis.
