The Monil collar has a top-mounted design that optimizes boundary accuracy and solar energy collection while protecting the electronics from impact.

A combined counterweight and buckle mechanism keeps the collar oriented and makes fitting easy.

The Monil collar is powered by the sun, continuously recharging itself while your animals graze. During the summer grazing season, solar charging alone is typically sufficient to keep collars operating without manual intervention.

In darker winter months, or in situations with extreme boundary interaction, some collars may require an occasional recharge using a physical charger. Chargers are included in the purchase, one charger for every 10 collars. With Monil, there are no battery replacements needed.

Built for real farm conditions, the Monil collar features a strong, secure locking system and a durable strap designed to stay in place. The strap is the result of extensive research and animal testing, shaped to fit the animal’s neck comfortably while remaining easy for ranchers to fit and adjust.

The locking mechanism is designed specifically for ranch use - simple to handle, secure in the field, and quick to apply. Bells can be added at the bottom of the lock for producers who want traditional audible tracking alongside virtual fencing.

Safety is built into the design. If an animal gets caught, the strap is designed to give under heavy pull rather than holding fast. This helps reduce the risk of injury. If a strap is damaged, it’s easy to replace by moving the unit onto a new strap with a screwdriver.

We take such pride in this design that we named the company after it - Monil, derived from the Latin word for necklace.

Monil guides animals using gentle, directional cues that help them learn and respect virtual boundaries. After a short training period, cattle learn to respond to sound frequencies as they approach the boundary.

As the animal turns its head, the sound frequency changes, indicating when its movement is aligned with the correct direction to move away from the boundary. Over time, livestock naturally adjust their behavior based on these cues, enabling effective, low-stress containment without physical fences.

Every Monil collar comes with a 5-year warranty, giving you confidence that your investment is built to last. It’s our commitment to quality, durability, and long-term reliability in the field.

Monil works without base stations or towers on your property.

The system operates using GPS and cellular connectivity, allowing you to set up and manage virtual fencing anywhere, with no additional infrastructure required.

All setup and fence management can be done through our self-service guides, and our customer success team is always available to support you if needed.

Because Monil collars rely on the mobile network, a minimum level of cellular connectivity is required at your operation.

What happens if connectivity is lost?

Virtual fences continue to function even if mobile connectivity disappears. The collars use GPS to keep boundaries active and animals contained. Cellular connectivity is required again to adjust fences, track animals, or receive alerts on your mobile device.
