Query: Range is severely limited

In reading the documentation, you should be able to get 90 feet out of one of these, however it does state that if there are metal items near it, the range could be limited. They also tell you that you need to house it indoors. In our house, the garage is the best location, due to the shape of our yard, however being in the garage, the range was limited to just over 30 feet (on maximum setting). I returned it and will buy an in-ground wired system.
