Cattle tags for
the open range.
A rugged, solar ear tag that sends GPS location and behavior from rangeland with no power and no coverage—and hands you the raw data to use however you want. Ranch-grade hardware, open data.
Use ours, or build your own.
Two sensors. The spatial and behavioral data rangeland research runs on.
Location (GPS)
GPS fixes become grazing distribution, terrain and slope use, distance-to-water, residency, and movement at landscape scale—the spatial backbone of rangeland and grazing studies, captured across the whole herd.
Grazing distribution and space-use, quantified.
Behavior (Accelerometer)
Triaxial accelerometer data, classified on-device into activity and rest for alerts—or pull the raw signal to train and validate your own behavior models. You decide the sample rate.
Behavior data without recapture—raw, when you want it.
Both streams come from a single solar ear tag—no collar, no gateways, no base stations—and arrive as clean, timestamped, exportable data you can publish on.
Open data. Ranch-grade hardware.
The data is completely open—export it, configure it, and send it to your own tools. The tag itself is built to disappear into the background: weatherproof, animal-safe, and running for years on solar in the roughest country there is.
- Public API
- Webhooks
- Open event schema
- CSV / bulk export
- Configurable sample rates
- Raw GPS & accelerometer
- SDKs & example notebooks
- Your dashboard, or ours
- Weatherproof & UV-resistant
- Animal-safe & strongly retained
- Years on solar — no battery swaps
- Certified for satellite
- Secure & remotely updated
- Survives heat, cold, dust, hooves
The data is open. The hardware is reliable. The system is programmable.
Collars are for virtual fencing. Location and behavior can come from a tag.
Affordable at scale
Collars run $150–$300+ per head and need large batteries to power virtual-fencing actuators. An ear tag drops the collar form factor entirely—smaller, cheaper, solar-powered, and deployable across whole herds at a fraction of the cost.
Designed for >90%
Retention in rugged country is the hardest hardware problem, and it’s the first thing we’re proving on our own ranch. Our enclosure and attachment are built to survive years in rough country—and we’ll publish the numbers.
Instrument the whole herd
Cheap, solar-powered tags make it practical to instrument entire herds—not just a small sample—so studies get larger sample sizes and longer deployments, with no battery swaps and no manual data recovery.
Built to run for years in the field.
Rugged by design
Built for longevity
Solar energy harvestingCustom hardware. Custom firmware. Standards-based satellite (3GPP NTN). Every component selected for durability, power efficiency, and years of maintenance-free operation.
Works on any network
Cellular where there’s coverage, satellite where there isn’t—so it keeps reporting from anywhere, and you’re never locked to one carrier or network.
Solar-powered & maintenance-free
Solar energy harvesting targets years of operation with no battery swaps. Deploy once; it keeps reporting through heat, cold, rain, dust, and hooves.
Offline-friendly
Built for places where the internet isn’t guaranteed: BLE setup in the field, last-known-location, low-bandwidth alerts, and sync-when-connected.
Send it anywhere. Leave anytime.
With most livestock tech, the data is the lock-in: it lives in the vendor’s app, in a format you can’t export, and the moment you stop paying, you lose your history. That’s backwards.
Export the raw data and send it anywhere—your own tools, a research pipeline, existing ranch software, or a spreadsheet. Export or delete it anytime.
- Public API, webhooks, and bulk export—send data anywhere
- An open event schema you can build alerts and automations on
- Configurable tracking profiles—tune the tag to your workflow
- Keep your existing visual / EID tag numbers—add telemetry
- No lock-in, no surprise data fees, no black-box pricing
Research-grade & exportable
Raw and classified data, timestamped and exportable as CSV, Parquet, or via API. Built for analysis, reproducibility, and publication—and we publish our own validation.
No recapture, no download
Data arrives over the air throughout the study—no collars to retrieve and no loggers to offload, so there are far fewer gaps in the dataset.
Programmable to your ranch
Configurable profiles and an open event schema let you tune sampling and wire up alerts—“text me if an animal hasn’t moved in 8 hours”—the way your ranch works.
Let’s build this together.
