Move cattle without moving fence.
Precise virtual boundaries and herd insight all from one collar

Virtual fencing, in plain terms
Instead of posts and wire, you set boundaries on a map in the app. Each animal wears a GPS collar. When a cow walks toward the boundary, the collar plays a sound. If she keeps going, a short electrical pulse follows. Cattle quickly connect the sound with the boundary and turn back on their own.

Full control from your phone
Create fences, move animals and track your herd at any time.
Unique insight into the herd
The app tracks each animal's location, activity, and rumination to alert producers about changes that could indicate heat, or an animal that may need attention.
A long-term overview
Record notes for individual animals to build a complete overview over time.

Instant alerts so you can act in time

I like being able to graze any shape or size of area simply by drawing the boundaries in the app. It helps me do a better job with rotational grazing and pasture management, especially during busy times on the farm.
Meet more Monil producers here ->I’d recommend virtual fencing to other cow-calf producers. It’d be hard to go back without it. Once you start using it, you start seeing all the different ways it can work on your operation.
Meet more Monil producers here ->What stands out to me about Monil is the people. The team has an energy, openness and hunger to find solutions, and you can tell they genuinely take ownership in what they’re building. I get the sense that they don’t just work for Monil, they are Monil.

My husband and I rotationally graze our herd, so moving cattle used to take up so much of our time. Now, it only takes a few minutes. We simply create a new fence in the app and lead the cows into their fresh pasture.
Meet more Monil producers here ->The collars have been really good. I’m away working most days, so being able to open the app and see where the cows are and that they’re moving about normally makes day-to-day management much easier.
