Bought a new-to-me 800 cyclo last spring from a dealer which was a great upgrade from my 400. The monitor was thought to be working, but I couldn"t get it working prior to planting. I have several on the shelf, I have a mix of Seed Flow II and Cyclomitor II and a Cyclomitor III. Which of these would be the best monitor? I am going to pick one and send it in to AgExpress or Sensor-1 for testing/repair and will send the six sensors in as well. I am going to have themn all converted to weatherpak connectors and get a new harness. Just wondered what monitor would serve me best and if I would need a different sensor. I believe I have the sensors with the red IH logo right now.
