Anybody used the portable electric bear fences??? I will be camping on Kodiak, thought one might save my expensive tipi from an inquisitive bear.

Lets see if I can beat him (anthracitic) to it?

You did, thank you for the link.

Here is another idea, although I think it might drive you nuts worrying about all the creatures that happen by.


Scroll down the page to Campers Alert.

Might be great for a military application?

The military has some pretty astounding personnel detection gear. An SF friend of mine showed me a sophisticated piece of gear that they used with their Philippines counterparts (that they were there to train) against the abu sayyaf. Heavy though.

Paul if you go to Kodiak you will most likely incounter more than just inquisitiveness.
I talked with a guy who went to Kodiak two years ago. Said the elec fence was the only thing that saved his deer- in camp.
They would leave camp and climb the ridge. He said they could watch the bear come to camp and walk around the fence. He either never tested it, or could sense it but it kept him off the meat for sure. They said they had two chargers. One for his camp and one for his meat. Dcell chargers. I bought one shortly after and intend to use it this summer on all our pack trips on the horses to suround the tent and camp area.
I bought mine from this place.

You can put together the charger etc cheaper from country supply

Here is a great little video clip to watch bears in action.

Thanks for the links, looks like I have some "shopping" to do.

Has anyone tried the solar charged electric fence generators for this purpose? They sell them at rural hardware supply stores.

most solar chargers are heavy--built to stay on a fence 24-7-365. Look for a portable charger for building temporary hors paddocks or strip-grazing pastures. They usually can be run from D batteries or hooked up to a deepcycle.

These guys aren't cheap, but they sell good quality stuff:

My setup. Must be a good bear repellant- havent seen one in camp, but then I have had only had one in this camp twice before in years of camping.
D cell batteries, but not as powerful as recomended, but much more portable. Only one ribon wire- hopefully they would put their nose on it to investigate. don

thanks for the visual.

Don- Could you expand some on your set-up? What's it weigh? What does it consist of?

06-19-2007, 06:50 PM
Don, if that's a Gallagher PortaFence B11 Energizer, that's what I'm using too.

06-19-2007, 08:43 PM
charged up with 6 D alkalines this Gallagher B 11 weighs about three and a half pounds.
I use 1/2 inch poly wire for visibility.
I am using steel posts with insulators, but shorter fiberglass posts with clips would be much lighter.
I have it grounded with the post it is sitting on- Fiberglass posts you would need something like an aluminum rain gutter nail (light and long).
The recomended setup consists of several wires , alternating ground and hot. This entails heaver posts or some braceng.
So much wire and height, means you cannot just step over it (necessiting a gate), and longer setup time, more stuff to carry, more chance of tangled mess when taking down and setting up a moving camp.
Look in horse supply, farm and ranch type stores for this unit @ about $100 when I bought mine.
Poly wire is poly string with stainless steel strands included. It is available in string, in 1/2 inch ribbon, and one inch ribbon.
I have heard some folks use fishing line to tie the wire to trees, but then you are in a low visibility situtation, or need as much string to go around a clearing.

a second wire close to the ground will help keep out coons similar sized pests if they are a problem.

fiberglass poles are super-light and easy to cut down to the needed length. You can probably find a way to make them sectioned so they pack shorter if needed.

Here is a commercial camp unattended with a regulation setup. At my visit the battery was dead, the solar pannel was too shaded to be effective, even without the early snow. There was no bear damage,so I assume the local bears which include Grizzlies, were conditioned while it was in operation.
This model Gallagher puts out 5000 volts, but needs an external battery. Since there is an Optima battery, I assume this had been in operation for about three months to run it down.
With an effective solar pannel, and battery, I use this model all summer. One should be able to get by with a smaller battery, barring extended sun blockage. don

there are few things to do to cut weight if you are flying or carryng it. first i dont take posts but carry plastic haystring. it is tied to wood posts or trees or bushes and the wire is strung through loops in the string for insulation. also you can bury a piece of fence wire for a ground. some times you must wet the earth to get good ground- figure that one out for yourself. grounds are very important for it to work. for stock i just string it thru the bushes and turn em out. no insulators required. a couple hundred feet dont short out-at least the horses dont thing so. ray

The "good grounding" via wet earth has to do with soil composition and dialectic strength. To decrease your ohm's of resistance, the water spreads out and "fills" air voids. What works even better than water though, is urine, due to the salts that are present = very good ground!

just make sure to shut the fencer off first!!!!

07-27-2007, 08:46 PM
ooppss...kinda forgot about this one...

Thanks for the info Don. I'm looking to hit up the local Tractor Supply to see about getting such a rig together for my tipi's.

Have you ever seen this controller.
It is intended for the bear bag that they sell with it but the weight is sure right. I am sure that you could rig something up for a small fence.

I have one on order, but I intend to use it as a bear bag.


07-30-2007, 06:08 PM
Nope...that's a new one...

Thanks...I definitely like the looks of that one!
