Crop Circle Handheld System


The Crop Circle Handheld System integrates our popular Crop Circle sensors, GeoSCOUT GLS-400 and our new FieldPAK PS-12 into a single, portable and easy-to-use scouting instrument. The Crop Circle Handheld System is ideal for plot work, field mapping and crop scouting. While weighing less than 8 lbs., the Crop Circle Handheld System is easy-to-handle and its light weight reduces user fatigue that is associated with similar, bulkier instruments.

Data is easily collected and stored using the Crop Circle Handheld system’s GeoSCOUT GLS-400 data logger. The data logger supports both plot and field data collection modes. To begin collecting crop data, simply toggle the instrument’s trigger switch mounted to the extension pole. Data will be automatically stored on a SD flash card for processing and analysis at a later time.
