Getting accurate information on population, spacing, skips and doubles is important to your planting operation. Todays optical sensors fallshort in delivering this information. Optical sensors use light beams to detect this information. The light beams are susceptible many things which can falsely report information. Dust can be falsely reported as seeds and can coat and damage the sensor.
To keep the optical sensors out of the dust they are commonly mounted in the middle of the seed tube. Mounting the sensor in the middle of the seed tube makes it difficult to report accurate spacing as the majority of seed delays happen at the bottom of the seed tube.
Optical sensors only look at what breaks beam. Two seeds moving together will be counted as one seed causeng your population count to be off.
Precision Planting solves this with WaveVision. WaveVision uses high frequency radio waves giving you three-dimensional look at seeds. The radio waves see mass not shape and know the difference between dust and seeds. Because of seeing mass and not shape it can detect doubles. Being able to see through dust, WaveVision is mounted at the bottom of the seed tube giving you the best possible information on population, spacing, skips and doubles.
