Bests & Worsts Reviews from Amazon

After 2 weeks of online research I was just getting ready to install an in-ground fence, when it occurred to me that there might be wireless units available. It turns out that there are, and this one seemed to have the features that I wanted -- the same features that I was looking for in an in-ground unit (performance, build quality, decent collar battery life). Before committing to wireless, you must understand the limitations of the wireless nature of the unit, and balance that with the your needs and the physical layout of your property. If all agree -- as it did with me -- the unit, when correctly installed and configured -- will perform almost as well as an in-ground installation. I setup the whole system in 1.5 hours, and that was taking my time. I setup the unit in the following steps, which made the most sense to me after reading the manual: 1) Measure your property and determine the radius/diameter of the free area desired. I measure the diameters and found their intersection as in woodworking. 2) Find the geometric center of your property and determine the point in your house this corresponds to. This will give you a starting point when you're going to decide where to permanently install it in the house. 3) Temporarily install the base transmitter at this location (a few feet off the ground, as indicated in the manual), and estimate the boundary line distance to set it to. 4) Walk around your property and test the farthest points that the boundary line should be set to (assuming that your property isn't perfectly round as is the case with me). Adjust the base unit setting until these points are correctly set.. 5) Permanently install the base unit, test again. 6) Train your dog. The physical construction of the base is plastic junk with a power supply, circuit board, and an antenna in it. I guess that's OK if you install it and never touch it again (as in my case), but if you're planning on using this on the go (as it is advertised) I would consider it a little on the cheap side. The construction of the collar receiver is very good. In short, if this type of unit will work for you, it's awesome compared with the installation hassles of an in-ground system. If your setup doesn't lend itself to wireless, you will be disappointed with the results. Recommended.
