The LED's activity is showing the kernels as they fall. It gives the user a real sense of being in touch with his planting process.

Get an Electrolee to assist you in cutting losses due to missed rows. The Electrolee has proven over the years that it soon pays for itself. With a set of electronic sensors strategically placed in your planter units, the Basic Planter Monitor can monitor seed flow or other activity as it happens during the planting process. This technology enables you to “see”, so to say, inside the seed tubes of your planter.

And all is monitored from the driver’s seat of your tractor. 

As the driver of the tractor proceeds with the planting process, he can confidently focus on the wider planting process, knowing the Planter Monitor will report a missed row as soon as it happens. Peace of mind is an immediate result of implementing an Electrolee Planter Monitor.

The moment a blockage is recognized, the alarm sounds, prompting the driver to stop. He can then rectify the problem swiftly. Only with this early warning system are you in the position to eliminate dead rows due to missed planting. The Basic Planter Monitor is always used as basis for the DIGITAL UNIT which is in essence a Population Calculator with many added functions.
