The only tester that works on both your fence and your battery

Traditional electric fence testers solve one problem: they tell you the voltage on the wire. But they can't safely measure a 12V battery — and standard multimeters, while great for batteries, will be damaged by the high-pulse voltage of an energized fence.

The Premier 1 Dual Digital Tester was engineered specifically to bridge this gap. Its automatic detection circuitry recognizes whether you're probing a high-voltage fence or a low-voltage battery, and switches measurement modes accordingly — no buttons, no manual configuration.

The result is one compact tool that replaces two, built by Premier 1 Supplies, a company that has supplied Iowa-based electric fencing expertise to farmers and ranchers for over four decades.

// Who It's Built For

Real farms.
Real problems solved.

🐄

Cattle Pasture Rotation

Verify fence is live before moving cattle to a new paddock. Target 3.0 kV+ at the far end of the wire.

🔋

Solar Battery Checks

Measure your 12V SLA battery directly. Below 12.2V means it needs a recharge before the next cloudy stretch.

🐑

Sheep & Goat Netting

Electric netting needs consistent voltage. Walk the perimeter and spot weak points caused by vegetation contact.

🦌

Deer Deterrent Fencing

Higher-tension fences require higher output. This tester confirms your energizer is delivering adequate deterrence.

🏕️

Off-Grid & Remote Setups

For cabins and remote properties, battery-powered fencing is common. Monitor charge levels without extra equipment.

// How to Use It

Three steps.
That's it.

STEP 01

Ground the probe

Push the black ground probe 3–4 inches into the soil near the fence. Always hold the probe by its handle, not the cord, to prevent damage.

STEP 02

Touch the fence wire

Bring the tester's metal tip to the electrified fence wire. The LCD display activates automatically and reads the voltage in kilovolts.

STEP 03

Read and act

Compare your reading to target values. Low voltage at the energizer suggests an equipment issue. Low voltage elsewhere suggests a fence issue.

// FAQ

Common questions

Why does my fence show low voltage even though the energizer is on?
+
Most commonly, vegetation touching the wire is draining current. Walk the fence line looking for tall grass or weeds in contact with the wire. Other causes include a poorly grounded energizer, a damaged section of conductor, or a weak battery powering the unit.
Can I use this tester without pushing the probe into soil?
+
No — the ground probe must complete the circuit to get an accurate fence reading. For battery testing, connect the ground probe to the negative terminal and the tip to the positive terminal instead.
What does "HI" or "LO" on the display mean?
+
"HI" means the measured voltage exceeds the tester's range (over 13 kV for fence, or over 18V for batteries). "LO" or "low batt" means the tester's own internal 9V battery needs replacing — not a reading of your fence or energizer battery.
Is it safe to use during rain?
+
The tester is designed for outdoor farm use, but avoid immersing it in water. Wet conditions can affect probe contact and readings — if it's raining heavily, wait for drier conditions for the most reliable measurements.
How is this different from a cheap light-up fence tester?
+
Light-up testers show a rough range via LEDs — useful but imprecise. This digital tester shows exact voltage to one decimal place (e.g. 6.4 kV), so you can identify gradual voltage drops over time and catch problems before they affect containment.
