Nofence Sheep & Goat GPS Collar

The Nofence Sheep & Goat Collar (SG2.5) is a solar-powered GPS collar that lets you graze sheep and goats without building fence — and it's the only virtual fence solution recommended by Powerflex. We vetted the options, put collars in the hands of producers on our own customer base, and Nofence is what held up in the field. Set virtual boundaries in the free Nofence app and the collar guides each animal with an escalating audio warning before any mild electric pulse — so your flock learns the line and stays put. Nofence reports a 99.7% containment rate across its fleet, from the most field-tested virtual fence on the market.

• Boundaries and exclusion zones from your phone — draw, move and resize pastures in seconds as conditions change, and fence stock out of creek bottoms, food plots, young timber and sensitive ground.
• Audio first, then pulse — the collar sounds a warning as an animal approaches the line and only pulses if it keeps going. If an animal pushes through, you get an escape alert on your phone.
• HerdNet™ collar-to-collar mesh — collars relay for each other, so the system keeps working in patchy cell coverage with no base station to buy, site or power.
• Solar powered — continuous solar charging with a rechargeable lithium-ion battery built for season-long field use.
• Below-the-neck design — roughly 1.12 lb and positioned to protect both the collar and the animal working through brush.
• Live tracking and health signals — continuous location and activity data, including alerts to changes in behavior that might indicate sickness, injury or distress. The system shows you where the herd has grazed so you can identify where the land needs to rest.
• Built for the field — IP67 weatherproof, rated -4°F to 140°F, with a 5-year collar warranty from Nofence.
• Connectivity — LTE Cat-M1 / 2G cellular, Bluetooth, GPS + GLONASS.
• One app, both species — run SG2.5 collars on sheep and goats alongside C2.5 or N3 cattle collars on the same account.
• Updates arrive automatically — new collar and app features are delivered over the air at no extra cost.

Fence the unfenceable

Steep, brushy and rocky ground that could never be physically fenced becomes grazable. Powerflex producers have used the SG2.5 for targeted brush and weed control on terrain that would never pencil out with wire — creek bottoms, rocky ridges, leased parcels with no infrastructure. It has also become the standard tool for contract grazing on solar sites and public ground — multiple sites, one app, no infrastructure left behind when the job is done. We recommended Nofence because we watched it work, on real operations, with real animals.

What comes with it

Each collar includes the rechargeable battery and wired charger. The first 12 months of Nofence subscription are included with purchase; a per-collar subscription continues monthly or annually after that and is managed directly through Nofence. One collar per animal with  5 collar minimum. Nofence also includes full app access, a U.S.-based support team, a 5-year collar warranty and a money-back guarantee if the system is not right for your operation — those terms are administered by Nofence, not by Powerflex.

Grants, cost-share and financing can apply to virtual fencing depending on your state, herd size and operation. See our EQIP cost-share and funding guide for how producers are getting fencing and water infrastructure funded, and talk to us before you order.

Nofence states that you retain ownership of your herd and land data, and that it is never sold or shared without your consent.

"I dreamed of using goats to transform our land, but the challenges of fencing this terrain seemed insurmountable. With Nofence, we've made it happen."
