Skaagen, some additional things to consider while you're installing the wire. When going to and from a bush/tree/flower bed the wires can touch each other. Remember, counter clockwise around the bush/tree/flower bed and make sure you take into account bush growth. You may have to trim around the bush until it reaches it's final size but it will sure beat re-installing the wire. Also, take into account that should you upgrade the newer units are wider so add a couple inches to the distant away from edge.
When the bot heads home and hits the wire going around a bush/tree it will make about 3 circular trips before it figures out it's not getting anywhere. At that point it will stop, turn and head off looking for the perimeter wire. Don't panic... :-)
Check out the 'boot' layouts if you want to break your yard up into different areas.
Note that the toe part in always next to the returning wire.
Have fun..... and you haven't seen anything yet. We name these little things and treat them like part of the family..... grown men and women doing this, so either we're crazy or......
Ahhhh, you have named your bot, right?
