Step 8: Mending the break

The final step is connecting the broken ends in a way that is weatherproof and secure. I bought these connectors from the local hardware store, time will tell if they are the best ones or not but you want something that is waterproof and suitable for the temperature range in your climate. This type of connector is filled with silicone to seal the twisted wires. Once you're sure the fence is operating correctly, bury the mended wires and you're done! Good luck!

In further looking over for options on the internet, I've found the $100-$200 wire break detect products range limited to 1000 ft. The Dogwatch team who did the repair used a Greenlee 501 product where the range goes to 4000 ft. (A distance that would cover a range of shapes for 6 acres). The only downside is the product is >$600 and a questionable investment I'm mulling over, for only home use with infrequent issues. http://www.greenlee.com/products/TRACKER-11%2540dCABLE-LOCATOR-(501).html?product_id=15377
your best bet for splicing the wires would be a direct burial splice tap. they are available at all electrical wholesate houses and most home improvement stores. while the connectors above will work, they can also allow current to find it's way into the ground. If it is alot of current, your breaker will trip. if it is under 80% of your breaker rating, it will just recognize a heavy load i.e. a toaster or coffee pot. this will result in you paying a higher electric bill. nobody wants that.
This kind of wire is like a alarm-system-wire, when the wire breaks a alarm will sound and the system  shuts off.
This kind of wire and system will carry a low voltage ( 3-5 volts ) with a 10 khz frequency.
If this kind of wire breaks with this system it will not increase the load but it will sound an alarm at the transmitter telling you that the loop is broken and that the system is not functioning.

I would use a propane powered soldering iron and solder the broken ends together and then put 2 layers of heat-shrink over it.

Or you could do it like electricians used to do in california 20 years ago.
Make your splice then use plumbers dough around the splice and then use electrical tape and tape wire and plumbers dough. This will give you a water tide splice for many years to come with just a few pennies worth of material invested.
