ALLmeter Tester: Safe, Battery-Free Fence Checks
Designed for safe testing without the risk of electric shock, the ALLmeter tester hooks directly to the fence wire and ground probe for immediate, shock-free readings. It supports quick fault diagnosis and voltage assessment across livestock fences, pasture lines, and horse facilities. The device is portable and requires no batteries, instead drawing power from the fence pulse itself. With an 8-level neon display, users can gauge whether a fence provides adequate protection to contain cattle, horses, sheep, or deter deer. Its long service life supports frequent inspections in busy farms.
ALLOSUN Fault Finder: Digital Fence Voltage Tester
The ALLOSUN tester provides a precise digital readout from 0.3 kV to 9.9 kV, with a 57-inch wire length for flexible use. Its power-saving design powers up when it detects a pulse and turns off after roughly four seconds without activity, reducing energy use while offering quick voltage checks along fence lines and controllers. This makes it suitable for farms needing immediate pulse verification and fault identification without constant power draw.
Electric Fence Charger AC Powered 80 Miles
This 110V plug-in energizer delivers broad coverage for large properties, capable of electrifying up to 80 miles or 250 acres. It features a sturdy outer casing and built-in lightning arrester, plus mounting versatility for T-posts or stakes. The device provides reliable low-impedance power with a maximum pulse voltage around 6.5 kV, helping deter predators and protect livestock over extensive fencing systems.
Gallagher Live Fence Indicator
The Gallagher Live Fence Indicator provides quick visual confirmation that a fence is live. It flashes with each pulse when the voltage is above 3,000V, enabling rapid checks from a distance. It is powered directly by the fence line, eliminating battery maintenance. The device is UV- and water-resistant, offering dependable performance across varying weather conditions while remaining highly visible in low light up to several thousand feet away.
Gallagher M10,000i Mains Energizer
The Gallagher M10,000i is a high-power mains energizer unit designed for large ranches and permanent fencing. It delivers up to 100 joules of stored energy and up to 71 joules of output, supporting long-distance voltage maintenance and reliability under heavy vegetation or fault conditions. Its iSeries remote monitoring compatibility enables fault alerts and performance visibility via the Gallagher Devices App when connected to a WiFi gateway, facilitating proactive fence management.
Buying Guide: Key Purchase Considerations
- Coverage and power: Match energizer capacity to your fencing length and livestock type. Larger properties with permanent fencing benefit from high-output models, while smaller setups can rely on mid-range units.
- Testing and fault finding: Combine a safe fence tester and a fault finder to quickly diagnose voltage levels and identify weak points without direct contact with live wire.
- Ease of installation: Look for plug-in or battery-free options for simpler setup and lower maintenance. Mounting options (T-post compatibility, weather resistance) are important for rural environments.
- Monitoring and alerts: Remote monitoring features help track performance over distance. Consider systems that offer app-based fault notifications for timely maintenance.
- Durability and weather: UV resistance, waterproofing, and robust casings extend life in sun, rain, and wind exposures common on farms and ranches.
- Safety and compliance: Ensure devices meet local electrical and livestock-safety standards, and use grounded testing to prevent accidental shocks during checks.
- Maintenance needs: Battery-free testers reduce ongoing costs, while indicators and fault finders support routine maintenance without specialized tools.
Choosing the right mains electric fence energiser involves balancing power, reach, monitoring capabilities, and maintenance needs. Combining a capable energizer with reliable testing tools helps maintain optimal fence performance and livestock security across varying farm layouts.
