The seed censors do not really work for milo on my 2012 air pro planter. I was told seed is too small to work good with my censors. The seed plants for milo do a good job of metering the milo. I think I have the monitor set to signal a failed row after no seed for 3 seconds, and low population warning at about 25% of target rate. I plant 15" row milo with my planter, it is a YP40.
