Hybrid Mode™

Hybrid Mode™ combines Soil and Crop Modes to monitor soil surfaces and crop canopies simultaneously. When canopies are patchy, it tracks the soil to create a continuous virtual canopy. This mode is perfect for in-crop spraying and navigating challenges like washed-out areas, thin or lodged crops, and wheel tracks.

Dynamic Chassis Sensor (DCS-1)

The DCS-1 sensor enhances boom control system stability and responsiveness, improving performance by over 30% in challenging conditions.

Advanced Ultrasonic Sensors

The MS-1 sensors utilize enhanced MAX Sense™ ultrasonic technology for exceptional performance in rugged terrain. Constructed from corrosion-resistant GF nylon and equipped with a protective transducer screen and multi-axis vents, these sensors offer increased durability and require less maintenance.
