Seco 40-Minute Heads-Up Level The Seco 5001-20 40-Minute Heads-Up Level is a safety-focused leveling accessory designed for surveying in active or high-traffic environments. Its unique “heads-up” viewing design allows operators to read the bubble level while maintaining a forward-facing position, reducing the need to look down during critical setups. This improves situational awareness in the field, helping users stay alert to surrounding traffic and site activity while still achieving accurate leveling. The direct-reading bubble provides quick, comfortable visibility for routine surveying tasks and coordinated field operations.
