This option can be used to make the installation of the Landroid much easier by eliminating the need to border inner turf areas with the main perimeter wire. This option is also ideal for temporarily excluding certain areas of lawn. For example, with seasonal garden equipment such as a trampoline - when you move it, the digital fence simply moves with it. You can also make a permanent change to your lawn without having to move the original perimeter wire of the Landroid. The Off-Limits option comes in two components: a sensor that is installed on board the Landroid and a roll of digital fencing strip to border the prohibited areas. The strip does not need to be connected to the perimeter wire and does not require a power supply. It works by magnetic force, which is detected by the sensor. Simply place the Off-Limits sensor on board your Landroid and border the designated areas with the digital fence strip.
