I rented an edging device with a spool to bury the line as it dug the mini-trench. There was a lot of tension, but the wire held up. I'm glad I used this instead of the 20g wire that came with the kit. Beware, the terminals on the PetSafe/DogSport hardware are insufficient to grip this wire. I worked around that issue by connecting a few feet of 16g stranded wire between my boundary wire and their transmitter.
