Halter

Solar collar virtual fencing and cow monitoring for dairy and beef grazing

As of 1 September 2026, Halter starts at 9.9/month. Virtual fencing sold as a solar collar plus a per-cow monthly subscription, with on-farm towers as a separate up-front install. Softwr lists it under Agriculture. Halter is available on iOS, Android, Web.

Overview

What Halter does

Halter puts a solar-powered collar on every animal and replaces internal fencing with GPS boundaries drawn on a phone. The collar cues the cow with sound and, if she ignores it, a mild pulse, so a herd can be shifted to a new break, held off a waterway or brought to the shed without anyone walking a paddock. On dairy farms the same collar does heat detection and health monitoring from activity and rumination signals, which is what turns it from a fencing product into a herd management system. On beef and rangeland operations the value is closer to labour replacement and grazing control across country too large to fence economically. The cost structure is what buyers get wrong. Halter is not a hardware purchase; it is an install plus an ongoing per-cow subscription. New Zealand dairy pricing starts around NZ$9.90 per cow per month after a substantial price cut, in tiers named Core, Pro and Unlimited, and there is a separate one-time infrastructure cost for the on-farm towers that give the collars coverage. Halter has arranged finance through the major New Zealand banks so the install can be spread over two years, with a discount for paying the subscription up front. A 500 cow dairy is therefore looking at a five-figure annual subscription forever, on top of the install, and the collars stop being useful the moment the subscription stops. That is the honest framing: this is a permanent operating cost, not a capital item that depreciates away. Buyers are grazing dairy operations in New Zealand and Australia, and increasingly large beef ranches in the United States, where the labour saved is measured in full-time equivalents. Halter is a strong fit where paddock shifts are frequent and staff are scarce, and a weak fit on set-stocked systems where fences already exist and nobody moves stock daily. The trade-off is a genuinely large labour reduction against an indefinite per-head bill and total dependence on one vendor for the collar, the towers, the app and the animal data.

What people use it for

  • A 600 cow grazing dairy that shifts breaks twice daily and cannot recruit enough staff to do it
  • A beef ranch fencing off riparian margins and wetlands without building physical fence
  • A dairy replacing a separate heat detection collar system with one collar that also does fencing
  • An operation running cell grazing on country where the cost of internal fencing exceeds the collar subscription

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Halter.

  • The subscription is permanent and per head, so a 500 cow dairy carries a five-figure annual bill indefinitely and the collars become inert if it lapses; there is no owned-outright end state.
  • On-farm tower infrastructure is a separate up-front install cost that is not in the headline per-cow price, and terrain with hills or bush can require more towers than the initial quote assumed.
  • Coverage is concentrated in New Zealand, Australia and parts of the United States; buyers elsewhere face no local support, no local install crew and uncertain regulatory acceptance of virtual fencing.
  • Virtual fencing is not universally legal or accepted: some jurisdictions and some organic or welfare certification schemes restrict aversive stimulus devices, which can decide eligibility before price is even discussed.
  • Total vendor lock-in on collar, towers, app and animal data means there is no second source for a replacement collar and no way to keep the fencing working if the commercial relationship ends.

Answered, with sources

Questions people ask

Each answer names the page it came from, so you can check it rather than take our word for it.

Do I buy the collars or rent them?

In practice you are buying into a per-cow monthly subscription plus a one-time install for the towers. The collars are not useful without an active subscription.

What does it actually cost for 500 cows?

Starting from around NZ$9.90 per cow per month, that is roughly NZ$59,000 a year before the one-time tower infrastructure cost, and it recurs every year.

Can I finance it?

New Zealand dairy farmers can finance the install through ANZ, ASB, BNZ or Westpac over two years, and paying the subscription up front attracts a discount.

Does it replace heat detection collars?

Yes on the higher tiers. That is the main reason dairies justify the cost, because it removes a second per-cow system.
