This review is from: Parmak MARK7 Low Impedance 110/120-Volt 30-Mile Range Electric Fence Charger (Lawn & Patio)

I purchased one of these to replace a failed Fi-Shock unit which died after 25 months service. That unit worked OK and made a gentle click, click, click noise every second or so as the high voltage impulse was sent down the fence.
The Parmak unit makes a noise more akin to a door banging shut - enough to cause a headache if working nearby. Since the manufacturer confirmed it was supposed to make that sort of noise, I will now have to sound proof it since is installed in my garage which is also a workshop. Even if you install this in a location where the noise won't bother you, it could well disturb any animals or livestock nearby.
A low-impedance fence charger is pretty simple to make - the only part of it that's not an off the shelf component is the inductor or transformer used to produce the high voltage output. Parmak told me the noise was caused by the laminations of the transformer's magnetic core knocking together. Probably true and a reflection of a cheap and crude manufacturing method or design.

I've now had this unit in use for 2 months and it's almost useless. My prior charger kept out deer 99% of the time. With this unit attached to exactly the same fence, they get in almost every day. The display on the unit claims an o/p voltage of about 13kV and the label says it will power 30 miles of fence. I have about 1600 ft, few or no weeds and the o/p measured with a fence tester at the terminals is just 9kV and it falls off measurably along the line.

Bottom line, this is a badly made ineffective piece of rubbish. Avoid.

After 2 other brands failed, I finally got a real fence charger. Unlike another reviewer's complaint, mine makes a little clicking sound as it's supposed to. My neighbor recommended this charger as his has been around since they were introduced. It has been energizing over 40 acres trouble free! And it is MADE IN THE USA!!!!! I love it and our cattle respect it!

I haven't used this Parmak fencer too long but it has worked fine for the time I have used it. I did have a Parmak before this one that lasted for years. So I am convinced they make a good product. I purchased this fencer through Amazon.
