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.

What it costs

Straight numbers, because this is the question everybody asks first.

• $269 per collar, one collar per adult animal. Lambs and kids under roughly six months typically follow their mothers uncollared.
• 5-collar minimum order — so the smallest order is $1,345.
• First 12 months of subscription included in that price.
• Year two onward: roughly $45 per collar per year. Nofence sets, bills and manages the subscription directly — not Powerflex — and can change it, so confirm the current rate with us or with Nofence before you budget. You can pay monthly or annually.

On 100 head that is $26,900 up front and about $4,500 a year after the first year. Run your own numbers in the calculator below.

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, plus 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."

Common questions

How much does a Nofence sheep and goat collar cost?
$269 per collar, with a 5-collar minimum order — so $1,345 to start. The first 12 months of subscription are included.

What does the subscription cost after the first year?
Roughly $45 per collar per year, billed monthly or annually by Nofence directly. Nofence sets this rate and can change it, so confirm before you budget.

Is there a minimum order?
Yes — 5 collars. The system relies on HerdNet collar-to-collar mesh, so it is designed to run as a group rather than on a single animal.

Will it hold goats?
Goats are the hardest class of stock to fence and the SG2.5 is built for them. Animals learn the audio warning quickly, and Nofence reports a 99.7% containment rate across its fleet. A trained flock stays put; expect a learning period at the start.

Do I need cell service?
Collars use LTE Cat-M1 / 2G and relay for each other over HerdNet, so the system tolerates patchy coverage without a base station. Total dead zones are still a problem — call us and we will talk through your ground.

Do lambs and kids need collars?
No. One collar per adult animal; young stock under roughly six months typically stay with their mothers.

Can I run it alongside cattle collars?
Yes. SG2.5 collars run on the same Nofence account as C2.5 or N3 cattle collars, in one app.
