Looking at putting together my own bear fence. The pronciple of how they work is not difficult. Looks like I can make a pretty light pack model for around $100. Plan is to use;
1. Fishock/Havahart Charger - http://www.fishock.com/store/electri...arger/bss-2lgx
2. Aluminum tent poles as posts and one will also act as ground spike.
3. Tese insulators for hanging wire - http://www.ebay.com/itm/7-8mm-Round-...item5d26eb55a1
4. Polywire - http://www.amazon.com/Zareba-Electri...9818955&sr=8-5
And a few other bits; reels for line, marker tape and a silnylon bag.
Plan to run as a 3-line set-up up to 40'x40' square, each line live. Also plan to have option of running a 4th ground line (in between top 2 lines) so I can run that as a ground if on gravel bank/poor earth grounding.
Any advice/thoughts from those who have built before?
