I have the 800#. I had trouble trying to time the throw times and consumption. I’ve also found the rain sensor to be iffy. I probably threw out 200-250 lbs. of protein that caked and molded in the trough. I’m wishing I would have gone with the All Seasons timed protein feeder.
We have 6 of the 1500s. All work great in having some kind of control over feeding. We are HF and has helped dramatically in cost reduction in protein. I purchased the Rainbird sensors and they work great in stopping feed from going to waste during rainy periods.
I bought 16. Saved $50,000 in feed costs the first year. The animals are still heavy and healthy, but have to browse a bit more. One recent Kudu weighed 822 lbs. The timers are set for 7 & 8 am, 4 & 5 pm so animal visibility has increased. The rain sensors work, but we disabled them. If it rains at 2-3 pm and clears up, no feed is dispensed. Our animals eat the wet feed whenever it happens to get wet.
