The Nofence N3 Cattle Collar is the next generation of the most field-tested virtual fence on the market — and it's the only virtual fence Powerflex recommends. We vetted the options, put collars in the hands of producers in our own customer base, and Nofence is what held up on real ground with real cattle. The N3 is what they built next: a maintenance-free collar carrying a 10-year warranty, the longest Nofence has ever put on a product.

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 herd learns the line and stays put. No posts, no wire, no fence to build on ground that was never going to pay for one.

• Boundaries and exclusion zones from your phone — draw, move and resize pastures in seconds as conditions change, and fence cattle 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. Most learn the sound in a few days and rarely take the pulse again. If one pushes through, you get an escape alert and a location.
• Three ways to stay connected — cellular first, on AT&T, T-Mobile and Verizon. HerdNet™ relays collar-to-collar when the signal is weak, with no base station to buy, site or power. And satellite connectivity is coming in spring 2027, for country with no cellular signal at all.
• Health, reproduction and grazing intelligence — continuous location and activity data in one app, including alerts to behavior changes that can flag sickness, injury or distress, and a record of where the herd has grazed so you can see which ground needs rest.
• Built to be left alone — maintenance-free, with new collar and app features delivered over the air at no extra cost.
• 10-year collar warranty — the most durable collar Nofence has built, and the longest warranty they have ever offered.
• Your data stays yours — Nofence states that you retain ownership of your herd and land data, and that it is never sold or shared without your consent.
• One app, both species — run N3 cattle collars alongside SG2.5 sheep and goat collars on the same account.

Fence the unfenceable

Steep, brushy and rocky ground that could never be physically fenced becomes grazable. Powerflex producers use virtual fence for targeted brush and weed control on terrain that would never pencil out with wire — creek bottoms, rocky ridges, leased parcels with no infrastructure and no reason to set posts. 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.

The first N3 collars ship in January 2027. Nofence is taking pre-orders now at an introductory price, held until October 31 or while supplies last. If you are planning a 2027 grazing season around virtual fence, this is the window.

If you need collars before then, you do not want the N3. The Nofence C2.5 cattle collar is in stock now and ships on our normal lead time. It is the collar currently running on most of the operations we have watched. Call us and we will tell you honestly which one fits your calendar — there is no reason to wait fifteen months for a collar if you are turning out next spring.

What comes with it

Full access to the Nofence app with new features delivered automatically, a 10-year collar warranty, a U.S.-based support team, and a money-back guarantee if the system is not right for your operation. A per-collar subscription is managed directly through Nofence. One collar per animal. 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.
