yellowjacket......has worked great for years!

I've used the Yellowjacket with the 4 "D" cells for many a camp out and it works just fine.

We often pack in 1/2 mile of polystring and fence off a large meadow with 15+ horses.

Thanks for the replies.  I posted this on a couple of other sites and the Yellow Jacket seems to be the way to go.  Had one here at the house years ago and it worked good.  Just didn't know if there was something better out there now. Thanks again

I use this for my mules. It works great and is very easy to use.

When we pack into wilderness areas, We often take in some fiberglass rods and a roll or two of poly hot string. Ive used various battery chargers over the years.  I use the the Yellowjacket now because it had a good price and was available at my local farm store. But all the brands I've used have worked, The big question is how long they last.

In the photo below we have strung 2 rolls of polystring ( 1/4 mile each) around this meadow and turned out 19 horses.  The lessons I have learned are:

Make it big,  When you get a large group of strange horses, the horses will challenge each other for leadership. They need room to get away  from each other. Too small of an enclosure and a horse will get pushed thru the hot wire. We often ride in with friends and horses are being introduced to new horses when we get to camp.

Don't leave the horses in overnight.  Deer, Elk and Moose will also use the meadows and have no idea what a hot wire is and will run thru it knocking it down, Sometimes even dragging it off.  I have frequently had to re-set up my fence in the morning.  I find it is better to high line the horses at night and use the charger to power a hot wire around my tent to keep snooping bears away at night.

I use the one Brushycreekranch uses but I know a lot of people who use the yellow jacket. Both are good chargers.
