How It Works
WatchTower continuously ingests over a million data points per vehicle each month, using advanced machine learning to detect potential breakdowns before they happen. When the AI engine flags an issue, a Diesel Laptops technician reviews the alert, validates the findings, and creates a repair plan. The result is a clear, actionable maintenance roadmap delivered straight to your team so you can fix problems early, avoid costly downtime, and keep your fleet moving.
