Why top-mounted:
There’s a reason we put the technology on top
The Monil collar is top-mounted by design, positioning the technology where it can perform at its best, with a clear view of the sky, better access to sunlight and less hardware hanging beneath the animal.
- Precise GPS performance: Positioned on top for accurate location tracking and virtual boundaries.
- Better solar exposure: More access to sunlight for reliable charging.
- Less in the way: The technology sits on top instead of hanging beneath the animal’s neck.
- Directional audio cues: Sound is directed toward the animal as it approaches the virtual boundary.
- Built for cattle: Protected electronics designed to stand up to everyday use.

Where Monil's value starts adding up
Value shows up in different ways, but for many operations it starts with time

The system practically pays for itself through the benefits it enables
Tick Creek Ranch, Missouri

Reduce feed costs: Extend grazing, improve pasture recovery, and reduce days on purchased or stored feed.

Reduced labor: Spend less time moving fence, checking cattle, and adjusting paddocks manually.

Earlier action: Spot unusual activity, stuck animals, or potential health issues sooner.

Better use of land: Make rotational grazing easier and put more acres to practical use.

Traditional fencing vs. Virtual fencing
Different tools for different jobs. Here's how the two approaches compare.

Traditional fencing
Built around physical infrastructure and manual work.
- Requires posts and wire
- Manual moves and repairs
- Fixed layout
- Visual barrier
- Escapes can affect entire herd
- Limited visibility into herd activity

Virtual fencing
Built around flexible boundaries and app-based control.
- Boundaries adjusted in app
- Adjust from phone
- Flexible layout
- Learned audio boundary
- Escapes typically limited to individual animals
- Real-time location and alerts

Now serving US producers
We know that every cattle operation looks a little different. Some producers want to start with a larger rollout, and others want to try virtual fencing with a smaller group first to learn how it works. With Monil, you can start out with as few as six collars and go from there.
Monil collars are now available for shipping, with local support in the Midwest. If you're located outside our priority support area, contact us to discuss the potential for your operation.

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.

Frequently Asked Questions
Every herd is different, but most cattle learn the audio cue within 3-7 days during the training period. Training starts inside a physical fence so cattle can safely learn the relationship between the sound and the grazing boundary.
The collar uses an audio cue first. If the animal continues moving beyond the boundary, a short electrical pulse follows. Over time, cattle typically learn to respond to the sound alone, with very few pulses needed.
Yes. The Monil app lets you see cattle locations, monitor activity, and receive alerts, helping you keep track of what is happening across the herd, even while away.
No. Monil uses existing cellular networks, so there are no towers or base stations to install before getting started. That means less setup and fewer things to manage.
The answer depends on the operation, but many producers are looking to reduce repetitive work like moving fence, checking boundaries, and making frequent pasture moves. For some, that means more time focused on herd health, pasture management, and planning the next move for the operation.
Physical fence still plays an important role around property lines, roads, and other high-risk areas. Virtual fencing adds flexibility inside those boundaries, making it easier to manage grazing areas and reduce internal fence work.
