The researcher can place a wooden stake at the reference mark with plot information if desired. Can be installed on all planters and is most commonly used in conjuction with Skytrip GPS tripping. System activates when the planter trips by depositing a dollup of chalk. Fully adjustable up, down, fore, and aft to get the exact placement you require and cut down on drift on windy days. Uses standard goaline or similar chalk.
