Since then I have plugged the device into the lawn, no more mines are actually been dug in the garden. However, I have not known that the tone that gives the device in the immediate vicinity is quiet audible, so that I first strained an extensive search for a warning sound imaging device in the house. The tone interferes but only if it is with the head next to the device. Installation is simple, the gun makes a stable impression. Overall, the success is the shocker far right, so 5 points.
