Hotline 47P20B Pocket Beeper Electric Fence Tester
The Hotline 47P20B Pocket Beeper provides a quick and convenient way to check whether an electric fence is live.
Unlike conventional fence testers that require physical contact with the fence or a ground probe, the 47P20B is an audible non-contact proximity tester.
Bring it close to the fence line and the tester provides an audible indication when electrical pulses are detected.
Non-Contact Electric Fence Testing
One of the biggest advantages of the Hotline Pocket Beeper is its simplicity.
There is no need for an earth stake or separate testing lead, and the tester doesn’t need to be physically connected to the fence.
This makes it particularly convenient for carrying out a quick check when inspecting an electric fence.
Audible Fence Power Indicator
When the 47P20B detects power on the fence, it produces an audible beep, giving you a simple indication that the fence is energised.
It’s particularly useful when you simply need to answer the question:
“Is this electric fence live?”
It does not provide a voltage measurement, so customers requiring an actual kV reading should choose a voltage tester or digital voltmeter instead.
Pocket Sized with Key Ring
The 47P20B is designed as a genuinely portable electric fence tester.
Hotline incorporates a key-ring attachment, allowing the tester to be kept with your keys or carried easily in a pocket so it’s readily available when checking fencing around an estate, farm or rearing area.
Ideal for Gamekeepers & Game Rearing
The Pocket Beeper is particularly useful for quick checks of electric fencing around:
- Pheasant rearing areas
- Partridge rearing areas
- Release pens
- Predator-control fences
- Poultry enclosures
- Livestock fields
- Paddocks
- Farms and estates
For gamekeepers managing several fenced areas, its compact size makes it easy to keep with you throughout the rearing and release season.
Battery Included
The Hotline 47P20B requires one CR2032 3V lithium battery, which Hotline states is included with the tester.
Important – This Is a Power Indicator, Not a Fault Finder
The 47P20B is designed to provide a simple indication that voltage is present.
Hotline specifically states that this model is not recommended for fault finding.
If you need to measure the actual fence voltage or locate problems along a fence line, Ellmor also stocks more advanced Hotline fence testers and fault finders.
